How to Make Tofu Cat Litter Pellets? Complete Guide to Commercial Tofu Cat Litter Production

If you want to know how to make tofu cat litter on a commercial scale, the basic process is straightforward: prepare the plant-based raw materials, weigh and mix the formula, form the mixture into pellets, dry and cool the pellets, remove fines, and package the finished cat litter.

Building a reliable tofu cat litter factory, however, requires more than following this basic process.

A factory making one natural 2 mm product does not face the same production requirements as an OEM plant changing between several colors, fragrances, pellet sizes, and private-label formulas. Raw material moisture, hourly capacity, automation, packaging, factory space, and finished-product requirements all affect how the line should be configured.

For commercial production, the better starting point is therefore not “Which machines should I buy?” but “What tofu cat litter do I want to manufacture, and what production system is needed to make it consistently?”

Recent Tofu Cat Litter Projects Under Development

RICHI is currently working on tofu cat litter projects with different raw materials, product specifications, production capacities, and factory conditions. The examples below show how widely project requirements can vary even within the same tofu cat litter category.

20+ Recent Tofu Cat Litter Projects | 0.5–7 T/H+ | New Plants | Existing Factory Upgrades | Standalone Machines | Multi-SKU Production

These projects show that there is no single formula or equipment configuration for every tofu cat litter factory. Raw materials may start with soybean residue, pea fiber, starch, or other suitable plant fibers, while finished products can differ in color, fragrance, pellet size, dust level, and other characteristics.

However, most commercial tofu cat litter plants are built around the same core manufacturing stages. Understanding these stages first makes it much easier to determine which equipment your own raw materials, formula, and production target will require.

What Is Tofu Cat Litter Made Of?

Commercial tofu cat litter is generally produced from plant-based fibers combined with starch, binders, and other ingredients according to the manufacturer's formulation.

Common raw materials may include:

• Soybean fiber or processed soybean residue
• Pea fiber and other plant fibers
• Corn starch
• Cassava starch
• Wheat-derived materials
• Bamboo or other plant fibers
• Guar gum and other binders
• Deodorizing ingredients
• Coloring ingredients
• Fragrances and other functional additives

There is no universal tofu cat litter formula. A manufacturer working mainly with dry soybean fiber and starch has different material-handling requirements from a processor trying to use wet soybean residue. Likewise, a plant producing one standard product can use a simpler dosing arrangement than a private-label factory handling several formulas in one day.

The formulation therefore influences more than the finished cat litter. It also affects weighing accuracy, mixing, liquid or micro-ingredient addition, pelletizing, drying, screening, and other production-line decisions.

If you already have your own formula, RICHI can evaluate the raw material characteristics and finished-product requirements first, then configure the process and equipment around them. If you have multiple formulas, there is no need to worry; we can customize an ingredient dosing system for you that allows for flexible formula switching, meeting the needs of long-term development for various cat litter products.

What Types of Tofu Cat Litter Can You Produce?

Commercial tofu cat litter is no longer limited to one natural-colored cylindrical product. Brands now differentiate products through color, fragrance, pellet dimensions, plant-fiber combinations, deodorizing functions, dust level, packaging, and other features.

This matters when building a factory because a production line designed for one stable SKU does not need the same flexibility as a line expected to make a broad retail or OEM product range.

Natural and Original Tofu Cat Litter

For manufacturers producing one or a few stable natural products, the production system can remain relatively straightforward. A typical configuration covers weighing, mixing, pelletizing, drying, cooling, screening, and packaging, with raw material preparation added where necessary.

This type of arrangement can be a practical starting point for a new investor who wants to control initial equipment cost before expanding the product range.

Different Colored Tofu Cat Litter

Tofu cat litter can be manufactured in natural, green, pink, brown, and other colors according to the product formulation. Some manufacturers also combine different colored pellets in the same retail product.

If several colors will be produced on one line, the engineering questions are not limited to whether coloring ingredients can be added. The dosing method, mixing uniformity, batch size, production sequence, residual material, and cleaning between product changes also need to be considered.

A factory making many colored SKUs may therefore need a more flexible weighing and mixing section than one making only natural tofu cat litter.

Scented Tofu Cat Litter

Green tea, coffee, milk, fruit, floral, and other fragrances may be incorporated according to the manufacturer's formulation and market positioning.

The equipment arrangement depends on the physical form and processing requirements of the additive. A powder ingredient may be handled through a small-ingredient dosing system, while a liquid ingredient may require controlled liquid addition or spraying. The stage at which an ingredient is introduced also matters when it is sensitive to subsequent processing conditions.

For factories producing several scented products, product changeover and cleaning should be included in the operating plan from the beginning.

Functional and Premium Tofu Cat Litter

Manufacturers may also develop products targeting lower dust, improved deodorizing performance, different pellet hardness, specific absorption or clumping characteristics, different plant-fiber combinations, or premium retail positioning.

Many of these characteristics begin with formulation. The production line then has to reproduce that formulation consistently under commercial operating conditions.

Equipment does not replace product development. Its job is to dose, mix, form, dry, screen, and package the selected formula with the consistency required for commercial production.

How Is Tofu Cat Litter Made in a Factory?

A typical tofu cat litter manufacturing process is:

Raw Material Preparation → Weighing & Dosing → Mixing → Pelletizing → Drying → Cooling → Screening → Packaging

Raw materials are first prepared according to their particle size, moisture, and physical condition. Ingredients are then weighed according to the formula and mixed uniformly. Powder or liquid additives can be introduced through suitable dosing systems where required. The prepared mixture enters the tofu cat litter pellet machine and is formed into the required pellet specification. The fresh pellets then pass through the necessary drying and cooling stages before screening removes fines and off-size material.

Depending on the product and factory standard, polishing, fines recycling, dust collection, automatic conveying, or more advanced packaging can also be added. The basic manufacturing route is not difficult to understand. The real engineering work begins when these individual processes have to be turned into a balanced commercial production line.

Below, we present three common tofu cat litter production schemes, widely used across Asia, Europe, and the Americas. Each is based on real client setups and refined through years of practical operation.

[Example 1]: 1T/H Tofu Cat Litter Processing Solution - Russia Project

Process flow: feeding - mixing - granulation - drying - cooling - screening - automatic packaging scale

This project adopts a fully automated design, achieving seamless connection from feeding to packaging. The raw materials are mixed with 70% pre-weighed Russian local soybean fiber and 25% Kazakhstan corn starch, which enter the WLDH-1000 horizontal mixer through a 500kg stainless steel hopper and complete uniform mixing in 8 minutes.

The granulation stage uses the SZLH-250 ring die cat litter granulator, equipped with a unique 3.5mmD-type mold, to produce 1.2T/H high-quality granules. The three-layer gas belt dryer reduces the moisture content to 12% through a gradient temperature of 85°C-65°C, and finally after countercurrent cooling and screening, it is accurately filled by a fully automatic packaging machine. The entire line has a special anti-freeze design, and the electrical components meet the GOST-R standard, which perfectly adapts to the severe cold climate in Russia.

[Example 2]: 1-2T/H Tofu Cat Litter Production Solution - Thailand Project

Process flow: PLC weighing system - liquid addition - mixing - granulation - drying - cooling - screening - manual packaging

Specially optimized for the high temperature and high humidity environment in Thailand, the production line is equipped with a PLC intelligent weighing system to accurately mix local soybean residue and cassava starch. The SLHY-0.5 double-shaft mixer completes the uniform mixing of raw materials and antibacterial liquid within 6 minutes, and the moisture deviation is controlled at ±0.8%.

The economical SZLH-250 ring die cat litter pellet machine is used with a 4mm mold, with an hourly output of up to 2 tons. The single-layer gas dryer solves the agglomeration problem caused by tropical climate through intelligent temperature control, eliminating the cooler and using a 48-hour natural cooling solution. The final product is bagged manually, which significantly reduces the initial investment cost and is particularly suitable for small and medium-sized investors in Southeast Asia.

[Example 3]: 3-4T/H Tofu Cat Litter Production Solution - Brazil Project

Process flow: PLC raw material weighing system - liquid addition & mixing system (1 cubic meter mixing bin) - granulation (1 cubic meter granulation bin) - cooling belt - manual packaging - electric bag sewing machine

In order to adapt to the customer's 7-meter-high factory building, an innovative sinking PLC weighing system is adopted. The raw material bin and the 1 cubic meter granulation bin form a buffer system to ensure that the SZLH-320 granulator can continuously and stably produce 3.5T/H of 5mm cylindrical particles. The breakthrough use of 6-meter stainless steel cooling belts to replace traditional cooling towers, combined with the factory ventilation system to achieve cost savings.

The manual packaging station is equipped with an electric bag sewing machine, which reduces equipment investment by 35% while ensuring production capacity. The entire line is specially strengthened with anti-rust treatment and uses 220V/60Hz Brazilian standard power supply, which is perfectly adapted to South American market conditions.

Each of these tofu cat litter production schemes is tailored to different factory conditions, business models, and product strategies. Whether you're planning a compact 2t/h startup line or a high-capacity turnkey factory, our team can help you design the best-fit configuration, match the most suitable equipment, and provide detailed cost analysis.

How to Build a Complete Tofu Cat Litter Production Line

A complete tofu cat litter production line is not simply a pellet machine connected to a dryer. The raw material section, batching system, mixer, pelletizer, dryer, cooler, screener, conveyors, and packaging equipment must work together at compatible capacities.

The final configuration should be built around six things: the finished product, raw materials, required output, level of automation, factory conditions, and investment plan.

Start with the Product You Want to Sell

Before choosing equipment, define the product as clearly as possible.

• Natural, colored, scented, or functional tofu cat litter
• Pellet diameter and shape
• One formula or multiple formulas
• Number of SKUs
• Target moisture and dust requirements
• Retail, OEM, or private-label production
• Packaging size and format

A producer running one natural product every day can keep the line relatively simple. An OEM manufacturer changing formulas, colors, fragrances, pellet specifications, and bag sizes needs much more flexibility in dosing, changeover, storage, and packaging.

Check the Raw Materials Before Choosing the Line

Dry soybean fiber and wet soybean-processing materials should not automatically be put through the same production design. Moisture, particle size, flowability, cleanliness, consistency, and the number of ingredients affect how the front end of the plant should be arranged.

This is especially important for tofu factories, soybean processors, starch producers, plant-protein companies, and agricultural processors that already have a potential raw material stream and want to turn it into a higher-value cat litter product.

Determine the Real Production Capacity

A 3 t/h pellet machine does not automatically mean that the complete factory will produce 3 t/h.

If the mixing section can supply only 2 t/h continuously, the dryer cannot remove enough moisture, or the packaging machine cannot keep up with the finished product, one of these sections becomes the bottleneck of the entire line.

RICHI therefore matches the capacity of the dosing, mixing, pelletizing, drying, cooling, screening, conveying, and packaging sections as one system rather than selecting each machine independently.

Choose an Automation Level That Fits the Business

Two factories with the same hourly output can have very different automation levels.

An economical line may use manual bag opening, simpler ingredient weighing, mechanical conveying, and semi-automatic packaging. A standard commercial line can add automatic batching, controlled liquid addition, PLC operation, and more automated material transfer.

For manufacturers with high labor costs, frequent SKU changes, or larger production schedules, more automation can reduce manual handling and improve batch consistency. For a new investor with a limited product range, a simpler arrangement may be the more rational starting point.

Design Around the Factory You Actually Have

Production-line layout cannot be separated from the building. Clear height, column positions, door locations, raw material access, finished-product warehouse location, ventilation, utility connections, and available floor area can all change the equipment arrangement.

If you already have a building, it is usually better to design around its real dimensions before equipment manufacturing begins rather than trying to fit a standard layout into the factory later.

Below are some of the featured cat litter factory projects we have done. You can also go directly to our case center to view more cat litter project information!

Full Set of Tofu Cat Litter Production Equipment

A tofu cat litter plant can include the following equipment. Some systems are essential, while others depend on the raw material, formula, automation level, and finished-product requirement.

Tofu Cat Litter Mixer and Dosing System

A simple product made from a few major ingredients can use a relatively economical feeding and weighing arrangement. Once the factory starts working with several formulas, colors, fragrances, or low-dose functional ingredients, dosing accuracy and repeatability become more important.

The mixer must also be sized to work with the downstream pelletizing capacity. A line loses efficiency if the pelletizer is repeatedly waiting for the next batch or the mixer is continually waiting for downstream equipment to clear.

Tofu Cat Litter Pellet Machine

The tofu cat litter pellet machine is the core forming equipment. Selection depends on required output, formula characteristics, pellet diameter, product shape, and how frequently the factory intends to change products.

Different dies can be prepared for different pellet specifications. Where several product sizes are planned, die changing and production changeover should be considered before the line is finalized.

Tofu Cat Litter Dryer

Drying is one of the sections most likely to change both equipment investment and operating cost.

A belt dryer machine should not be selected only from the hourly tonnage of pellets. What matters is the actual moisture that must be removed. A 2 t/h factory starting with a wetter formula can require substantially more drying duty than another 2 t/h plant working with relatively dry ingredients.

Incoming moisture, final moisture target, throughput, heat source, local energy prices, product characteristics, and available factory space should therefore be considered together.

Screening, Dust Control and Packaging

Screening removes loose fines and off-size material before the product reaches the customer. Where a brand is targeting a particularly clean or premium finished product, additional polishing and dust-control measures can be considered.

The packaging section must also match the commercial model. Filling a limited number of larger bags is quite different from producing several small retail packages for an OEM or private-label business. Packaging speed can become a real line bottleneck if it is treated as an afterthought.

How Product Requirements Change Equipment Configuration

The table below shows why two tofu cat litter factories with the same hourly capacity can require different equipment.

The equipment configuration should follow the tofu cat litter you want to manufacture, not the other way around.

This is why RICHI asks about the formula, product range, capacity, packaging, and factory conditions before finalizing a complete equipment list.

Featured Tofu Cat Litter Factory Cases

Below are several tofu cat litter and cat litter production projects completed for customers in different markets:

• 1-2T/H Tofu Cat Litter Production Line in Iran
• 500KG/H Cat Litter Production Line in Bangladesh
• 3 T/H Tofu Cat Litter Factory in Vietnam
• 1-2 T/H Tofu Cat Litter Production Line in Germany
• 1-2T/H Cat Litter Production Line In Indonesia
• 3-4 T/H Tofu Cat Litter Making Machine in New Zealand

These projects should not be read simply as capacity references. Their real value is showing how raw material conditions, factory buildings, automation targets, product specifications, and investment priorities lead to different production solutions.

Have Soybean Residue or Plant Fiber? Can You Turn It Into Tofu Cat Litter?

For some tofu manufacturers, soybean processors, starch plants, plant-protein producers, and agricultural processors, the starting point is not “I want to build a cat litter factory.” It is “I already have this plant-based material—can it become a saleable cat litter product?”

Some soybean-derived and plant-fiber materials can potentially be used in tofu cat litter formulations, but suitability should be evaluated rather than assumed.

Important factors include:

• Moisture content
• Fiber characteristics
• Particle size
• Cleanliness and consistency
• Available daily or annual quantity
• Storage characteristics
• Compatibility with the intended formula
• Required finished-product properties

Wet soybean residue is a good example. It cannot simply be treated like dry commercial soybean fiber because the additional water changes storage, feeding, drying load, energy demand, and potentially the whole economic balance of the project.

If you already have a potential raw material, provide its description, moisture content, available quantity, photos or test information, and the cat litter product you want to develop. This gives the engineering team a much better basis for evaluating whether the material is suitable and what processing route would be required.

What Capacity Tofu Cat Litter Production Line Should You Build?

The right capacity should come from expected sales and production planning, not simply from choosing the largest pellet machine that fits the budget.

Hourly capacity should be checked against annual sales targets, operating days, shifts, operating hours, and realistic utilization.

For larger plants, pelletizing capacity alone becomes less useful as a planning figure. Raw material storage, dryer duty, packaging speed, dust collection, internal logistics, and production scheduling all become increasingly important.

How Much Does a Tofu Cat Litter Production Line Cost?

For preliminary budgeting, a complete commercial tofu cat litter production line can range from approximately US$50,000 to US$700,000+, depending on capacity and configuration.

These figures are useful for early project budgeting, but they are not fixed quotations.

Consider two 2 t/h factories. One uses dry ingredients, one stable formula, manual feeding, and semi-automatic packaging. The other needs automatic ingredient dosing, several colors and fragrances, liquid addition, more drying capacity, PLC control, enhanced dust collection, and automatic small-bag packaging.

The nominal output is the same. The equipment package is not.

The main factors affecting tofu cat litter production line cost are capacity, raw material moisture, formulation complexity, drying duty and heat source, number of SKUs, automation, dust control, packaging, factory conditions, and local electrical requirements.

What Does It Cost to Produce Tofu Cat Litter?

The cost of buying equipment and the cost of producing one ton of tofu cat litter are two different calculations.

Operating cost normally includes plant fiber and starch, binders and additives, electricity, drying fuel or heat, labor, packaging, maintenance, and other factory expenses.

A single global “cost per ton” is not particularly useful because soybean fiber, starch, fuel, electricity, labor, and retail packaging can vary greatly from one country to another.

For a practical estimate, start with local prices. If you know the approximate cost of your main raw materials, electricity, heat source, labor, packaging, planned capacity, and operating schedule, these figures can be used to build a preliminary production-cost calculation for the project.

Different Needs Require Different Tofu Cat Litter Production Solutions

A standard equipment list should not simply be copied from one project to another.

A factory using dry, stable raw materials and producing one standard SKU may prioritize a compact and economical process. Another project using wetter ingredients may put far more emphasis on drying. An OEM factory handling several brands may spend more on batching accuracy, flexible additive handling, product changeover, automatic control, and packaging.

The building can change the solution as well. A low workshop may require a different conveying route from a tall plant that can use more gravity transfer. An existing factory with useful mixers, dust collectors, or packaging equipment may be able to retain some assets after their capacity and compatibility are checked.

The purpose of customization is not to add more equipment. It is to use the equipment the project actually needs and avoid unnecessary investment where a simpler arrangement can achieve the required result.

Can RICHI Configure a Production Line Around Your Tofu Cat Litter Formula?

Yes. If you already have a mature or preliminary tofu cat litter formula, the equipment can be selected around the processing requirements of that formula and the product you plan to sell.

This is relevant to existing tofu cat litter brands, OEM and private-label manufacturers, cat litter factories adding a tofu product range, companies developing colored or scented products, factories making several pellet specifications, soybean-processing businesses looking for a new use for suitable byproducts, and existing plants planning expansion or automation.

You do not need to select every machine before contacting RICHI.

Tell us what you want to produce, what raw materials you have, and what output you need. From there, the engineering team can work backward to determine the appropriate process, equipment, automation level, and layout.

What Information Is Needed to Design Your Tofu Cat Litter Factory?

For an initial technical proposal and quotation, provide as much of the following information as possible:

1. Country where the factory will be built
2. Raw material types
3. Raw material moisture
4. Formula or approximate ingredient ratios, if available
5. Required capacity in t/h or tons/year
6. Pellet diameter and product shape
7. Colors, fragrances, or functional additives
8. Number of products or SKUs
9. Required packaging sizes
10. Factory dimensions or existing building drawings, if available
11. Local voltage and frequency
12. Required automation level or investment budget

With these details, RICHI can prepare a preliminary process flow, complete equipment list, production-line configuration, factory layout, and equipment quotation for the project.

Frequently Asked Questions About Tofu Cat Litter Production

1. How is tofu cat litter made commercially?

Commercial tofu cat litter is generally produced through raw material preparation, weighing and dosing, mixing, pelletizing, drying, cooling, screening, and packaging.

Crushing, micro-ingredient dosing, liquid addition, polishing, fines recycling, dust collection, and automatic conveying can be added where the formula or factory requires them. A commercial tofu cat litter manufacturing process is therefore configured around the actual product rather than copied as one fixed flow for every plant.

2. What raw materials are needed to make tofu cat litter?

Typical raw materials include soybean fiber or processed soybean residue, pea or other suitable plant fibers, corn or cassava starch, guar gum or other binders, and optional functional ingredients.

Colored or scented products may also use coloring ingredients, fragrance ingredients, deodorizing materials, or other additives. The exact formula is product-specific, so the production equipment should be selected after the material characteristics and processing requirements are understood.

3. Can soybean residue or tofu waste be used to make cat litter?

Potentially yes, but the first issue to check is moisture. Fresh soybean residue can be much wetter than dry commercial soybean fiber, which changes storage, handling, dryer load, and energy consumption.

Before designing a line around tofu waste or soybean-processing residue, provide the moisture content, physical condition, available quantity, and intended product. Wet material should not simply be fed into a standard dry-material line without evaluating the additional moisture-handling requirement.

4. What equipment is needed to make tofu cat litter?

A commercial tofu cat litter factory normally uses feeding, weighing and dosing, mixing, pelletizing, drying, cooling, screening, conveying, and packaging equipment.

Depending on the project, the line may also include a crusher, micro-ingredient or liquid addition system, polishing equipment, fines recycling, dust collection, automatic batching, and PLC control. The tofu cat litter pellet machine is the core forming machine, but it is only one part of the complete line.

5. How much does a tofu cat litter production line cost?

A complete commercial tofu cat litter production line typically requires an equipment budget of about US$50,000–700,000+, depending on capacity and configuration.

As a preliminary reference, a 1–2 t/h line may be around US$50,000–120,000, a 3–5 t/h line around US$80,000–250,000, a 6–10 t/h line around US$180,000–450,000, and a larger or highly automated 10 t/h+ plant around US$300,000–700,000+.

Raw material moisture, drying duty, automation, number of formulas, additive systems, dust control, packaging, and factory conditions can move a project within or beyond these ranges.

6. How many workers are needed to operate a tofu cat litter factory?

For preliminary staffing, a small or medium commercial tofu cat litter factory can reasonably plan for about 4–10 people per operating shift, although the number of direct production-line operators may be lower in a highly automated plant.

The total shift normally includes more than the people standing at the machines. Raw material feeding, production monitoring, bagging, forklift or material movement, warehouse work, quality checks, and basic maintenance all add labor.

In a highly automated line, roughly 3–5 people may handle the core production operation, while factories using more manual feeding, bag handling, and packaging can require considerably more staff. The final staffing plan should therefore be made together with the automation and packaging design.

7. Does tofu cat litter production require a dryer?

For most commercial tofu cat litter production systems, drying is an important stage after forming.

The main question is not simply whether a dryer is required, but how much moisture it needs to remove. A line using wetter ingredients needs more drying duty than a line working with a relatively dry formula. Incoming moisture, hourly output, final moisture target, heat source, and product characteristics should therefore be used to size the drying system.

8. Can one production line make different colors of tofu cat litter?

Yes. One properly configured line can manufacture different colored tofu cat litter products.

The main engineering considerations are ingredient dosing, mixing uniformity, production sequence, residual material, and cleaning between batches. If color changes are frequent, the batching and mixing system should be designed for practical changeover rather than only for one permanent recipe.

9. Can one line make different fragrances?

Yes. The line can be configured for several scented products, but the additive system should match the actual fragrance ingredient.

Powder and liquid additives may require different handling methods, and the preferred addition point may change according to the formulation and processing conditions. Frequent fragrance changes also make cleaning and batch scheduling more important.

10. Can one tofu cat litter line produce different pellet sizes?

Yes. Different pellet specifications can generally be produced by using suitable dies and adjusting the related production settings.

If several sizes will be made regularly, die changing, downtime between products, finished-product screening, and production scheduling should be considered when the plant is designed.

11. Can I use my own tofu cat litter formula?

Yes. RICHI can configure the production equipment according to the processing requirements of a customer's existing formula.

The most useful information includes raw material types and approximate ratios, moisture, powder or liquid additives, pellet size, required output, and finished-product requirements. If the formula is confidential, equipment selection can still be discussed around material properties and processing requirements without publishing the formulation.

12. Can one production line manufacture multiple tofu cat litter formulas or SKUs?

Yes. A multi-SKU plant can be designed with flexible weighing, dosing, additive handling, die changing, production scheduling, and packaging.

The more frequently formulas and finished products change, the more important changeover time, cleaning, recipe control, intermediate storage, and packaging flexibility become. This is particularly relevant for OEM and private-label factories.

13. Can I add a tofu cat litter production line to an existing cat litter factory?

In many cases, yes.

Existing buildings, warehouses, packaging areas, utilities, dust collection, conveyors, or other auxiliary systems may be reusable if their capacity and material compatibility are suitable.

However, tofu cat litter, bentonite cat litter, wood cat litter, and paper cat litter have different processing characteristics. Existing core equipment should be checked machine by machine rather than assuming the entire old line can simply be converted.

14. Can my existing equipment be used in a new tofu cat litter production line?

Possibly. Existing storage, crushing, mixing, conveying, dust collection, packaging, or utility equipment may be retained if it has suitable capacity, construction, and operating characteristics.

Before replacing everything, provide the model, capacity, photos, and available technical data for the existing machines. The new line can then be designed around equipment that is genuinely worth keeping.

15. Can a tofu cat litter production line be expanded later?

Yes, but future expansion is easier and cheaper when it is considered during the first layout.

Moving from 1–2 t/h to 3–5 t/h may require additional pelletizing capacity, more drying duty, larger raw material storage, faster packaging, upgraded conveying, and more electrical capacity.

If expansion is already part of the business plan, reserve floor space, conveying routes, electrical capacity, and connection points before the first-stage equipment is installed.

16. How much factory space is needed for a tofu cat litter production line?

For initial planning, a 1–2 t/h commercial project may use roughly 400–1,000 m² of production or workshop space. Once raw material storage, finished-product storage, aisles, utilities, and working areas are included, the total building requirement can reach about 800–1,500 m² or more.

Larger lines need more space, but capacity is not the only factor. A taller workshop can use more vertical conveying and gravity transfer, while a low building may need a more spread-out layout.

If you already have a factory, provide its length, width, clear height, column positions, and door locations. A real layout is more useful than applying a generic square-meter figure.

17. How much electricity does a tofu cat litter production line use?

For preliminary utility planning, a 1–2 t/h tofu cat litter line may require roughly 100–200 kW of installed electrical capacity, excluding the thermal energy required by the dryer. A 3–5 t/h line can move into roughly the 200–400 kW range or higher as pelletizing capacity, conveying, fans, screening, dust collection, and packaging increase.

These are planning allowances rather than fixed consumption figures. Actual connected load depends on the selected machines, and electrical demand should be separated from dryer heat demand because drying may use gas, biomass, steam, electricity, or another heat source.

The final power list is calculated after the complete equipment configuration is fixed.

18. How long does it take to build a tofu cat litter factory?

For many small and medium projects, equipment manufacturing may take approximately 30–60 working days. Shipping, installation, commissioning, and training come after that and vary by destination and project scope.

A practical way to shorten the overall schedule is to prepare the workshop, foundations, electrical supply, heat source, and utilities while the equipment is being manufactured rather than waiting until the machinery arrives.

19. What capacity tofu cat litter production line should I choose?

For a new commercial project or market-entry product line, 1–2 t/h is a practical starting range. An established regional producer may consider 3–5 t/h, while 6–10 t/h and larger systems are more suitable when confirmed sales, OEM orders, or export volumes justify the additional investment.

The capacity decision should come from annual sales, production days, shifts, operating hours, and realistic utilization. Oversizing ties up capital; undersizing can force an early and expensive expansion.

20. What information do I need to get a tofu cat litter production line quotation?

For a useful initial quotation, provide at least the raw materials, raw material moisture, required capacity, pellet specification, packaging size, and destination country.

If available, also provide your formula, color or fragrance requirements, number of SKUs, existing equipment, factory dimensions, required automation level, and investment budget.

With these details, RICHI can prepare a more meaningful process flow, complete equipment configuration, factory layout, and quotation than a generic price based only on hourly capacity.

Build the Tofu Cat Litter Line Around Your Product

You may be starting a new tofu cat litter factory, adding tofu litter to an existing cat litter business, developing an OEM production facility, expanding an existing plant, or looking for a higher-value use for suitable soybean or plant-fiber materials. These projects begin in different places, but they all need the same thing before equipment is finalized: a clear understanding of the raw material and the product to be manufactured.

You do not need to have every technical detail ready.

Start with your raw material, moisture, target product, required capacity, packaging, and country. If you already have a formula, factory drawing, existing equipment list, product sample, or target cat litter specification, provide those as well.

RICHI Machinery can use that information to develop the processing route and recommend the required equipment, optional systems, automation level, layout, and preliminary investment range for your tofu cat litter production project.

At present, our main projects are concentrated in the production range of 1-4t/h, but we also have several large-scale tofu cat litter production line projects. Here we will share two of them with you.

[CASE 1 ]10T/H tofu cat litter factory in Kazakhstan

This is a tofu cat litter factory in Kazakhstan project. The client is a pet food company. Based on the good development prospects of the pet products industry, the client decided to invest 430,000 US dollars to build a cat litter production line project with an annual output of 50,000 tons. The project produces 10 tons of tofu cat litter per hour.

Construction content and scale

The cat litter factory in Kazakhstan project produces 50,000 tons of cat litter per year. The project covers an area of 2,000 square meters (3 acres) and a total construction area of 2,000 square meters. The main construction area includes 2,000 square meters of factory buildings, 1,000 square meters of raw material and finished product warehouses, and 200 square meters of office areas.

This project will build 2 production lines in two phases. After the project is completed, it will produce 50,000 tons of cat litter per year. The project has a labor quota of 20 people, 300 working days per year, and adopts a two-shift 16-hour work system. The composition of the project is shown in the following table:

Raw and auxiliary materials

The main raw and auxiliary materials of this cat litter factory in Kazakhstan project are wheat flour, corn flour, tofu residue, etc. The project area has a well-developed transportation network, and raw and auxiliary materials can be purchased locally and in surrounding cities.

The market supply is sufficient to meet the production needs of the project. The consumption of raw and auxiliary materials is shown in the table below.

Production equipment

The main production equipment of the two phases of this cat litter factory in Kazakhstan project is the same, see the table below for details.

Public works

Water supply

5. russia cat litter factory Process flow design

The 16-17tph Russia automatic tofu cat litter pellet production line project uses soybean fiber, walnut wood, corn flour, water, etc. as the main raw materials to produce cat litter through batching, mixing, granulating, drying, screening, and packaging. After the whole cat litter manufacturing palnt project is completed, it will produce 40,000 tons of tofu cat litter and 40,000 tons of plant cat litter.

The production process of tofu cat litter is the same as that of plant cat litter, only the ratio of raw materials is different. This cat litter factory project has a total of 4 kitty litter pellet production lines with the same production process and capacity.

1. Material storage
   The raw materials of the cat litter factory project are soybean fiber, corn starch, and walnut wood in bags, all of which are purchased. The raw material truck is a closed transportation vehicle, which will be stored directly after entering the litter pellet factory.
2. Batching and mixing system
   The raw materials are transported to the workshop by the human material trolley, and they are manually put into the feed opening of the elevator in the batching room. The weight of the materials is automatically measured, and the materials are conveyed to the mixer by the enclosed screw elevator. Water is added in proportion, and the materials are fully mixed and the mixing is confidential. 
3. Granulation system
   The uniformly mixed wet material is transported to the cat litter sand pellet machine by the closed elevator. The steam enters the cat litter making machine through the pipeline and directly contacts the material for granulation. The granulation is confidential and the steam does not overflow. The wet material is squeezed in the cat litter pellet machine.
4. Drying system
   The finished product of granulation is conveyed to the drying bin by the airtight conveyor belt, and dried by steam heating. The drying bin is airtight. There is an induced draft fan in the drying bin.
5. Screening section
   After the material is dried, it becomes a large pellet product. The dried product is transported to a vibrating screen by a conveyor belt for screening. According to product requirements, product pellets with a particle size of <5mm are unqualified products and are screened through the screening process. In addition, unqualified products are collected and reused for production. The materials move with the vibration of the vibrating screen into the cat litter packing machine for packaging process.
6. Packaging system
   The materials are sent into the cat litter packaging machine in equal amounts along with the vibration, and the packaging machine automatically bagging and sealing. After the bagging is completed, the products are waiting for sale.
