1.5–2.0 T/H Dog Food Machine for sale in United States

Customer Background and the Reason for Buying One Extruder

The customer is an independent pet food manufacturer preparing to produce dry extruded dog food for regional distribution in the western United States. Rather than competing immediately on very large production volume, the company’s initial strategy centered on several differentiated formulas, controlled batch production, and the ability to change recipes and kibble specifications as its customer base developed.

The company had already planned the upstream grinding, weighing, mixing, and ingredient handling sections as well as downstream drying, coating, cooling, and packaging. What it needed from RICHI was the extrusion section.

For that reason, this was a single-machine project rather than a complete dog food production line. The customer selected one SPHS120×2 twin-screw extruder to establish its initial commercial extrusion capacity while retaining flexibility for future expansion.

This configuration made more sense than selecting equipment solely around an optimistic future sales forecast. A pet food startup needs enough capacity to support growth, but an unnecessarily large extruder also increases supporting-equipment capacity, utility demand, initial investment, and minimum economical production batch size.

Why the SPHS120×2 Was Selected

The customer expected the extrusion section to operate around the 1.5–2.0 T/H level for its initial product portfolio. The SPHS120×2 therefore provided an appropriate starting point for the planned commercial scale.

The capacity is treated as a working range rather than a fixed output. Extruder throughput changes with formula composition, starch characteristics, fat level before extrusion, feed moisture, screw configuration, die restriction, kibble density, expansion requirement, and cooking conditions.

This distinction is particularly important for premium pet food. Two recipes using the same die diameter can place very different loads on the extruder.

Premium Dog Food Formulations Require More Than a Different Die

The Colorado customer planned several recipes using animal protein meals together with alternative carbohydrate and fiber sources such as peas, chickpeas, potato ingredients, and selected vegetable components.

The formulations also incorporate fats, vitamins, minerals, amino acids, and other nutritional components according to the nutritional specification of each product.

Not all fat is necessarily introduced before extrusion. Excessive pre-extrusion fat can reduce mechanical energy input and influence expansion. Depending on the recipe, part of the oil or fat can instead be applied after drying through the coating section.

This provides greater control over both processing behavior and finished-product palatability.

The customer therefore did not purchase the SPHS120×2 simply because it was described as a “grain-free dog food extruder.” The machine was selected because a twin-screw extrusion platform provides useful process flexibility when a manufacturer expects to work with formulations whose starch, protein, fiber, moisture, and fat characteristics vary substantially between products.

Why Twin-Screw Extrusion Fits This Project

Alternative starch ingredients do not behave exactly like conventional cereal-based formulas during extrusion. Pea, potato, chickpea, and similar ingredients differ in starch composition, protein level, fiber content, water absorption, and extrusion response.

A twin-screw configuration gives the operator greater control over material conveying, mixing, shear, cooking, pressure development, and discharge behavior.

This does not mean that every grain-free formula automatically requires twin-screw extrusion. Well-designed single-screw systems can manufacture many pet foods successfully. For this customer, however, recipe flexibility was particularly important because the business intended to develop several premium SKUs rather than manufacture one high-volume standard formula continuously.

Raw Material Preparation Before Extrusion

Extrusion performance begins well before material enters the SPHS120×2.

Dry ingredients are ground to an appropriate and reasonably uniform particle size before batching. Protein meals, starch ingredients, fiber sources, minerals, and other dry components are then accurately weighed and mixed.

This is especially important for a manufacturer producing several formulations. Poor mixing cannot be corrected by the extruder, and inconsistent particle size can create fluctuations in water absorption, cooking, pressure, expansion, and finished kibble appearance.

Low-inclusion ingredients also require accurate dosing. A commercial dog food manufacturer cannot rely on approximate addition of premixes, minerals, amino acids, or other micro-components.

Pre-Conditioning before the SPHS120×2 Extruder

Before entering the extrusion barrel, the mixed material passes through the conditioning system, where steam and/or water are introduced according to the formula.

Pre-conditioning begins hydration and thermal treatment and helps prepare the mash for the more intensive cooking and mechanical treatment inside the extruder.

There is no single correct conditioning temperature or moisture percentage for every dog food recipe. The appropriate settings depend on starch source, protein composition, fat level, fiber, desired expansion, extruder configuration, and final kibble characteristics.

During commissioning, these variables are adjusted using the customer’s actual formulations rather than applying one fixed parameter to puppy, adult, and senior recipes.

Inside the Dog Food Extruder

Once conditioned material enters the twin-screw barrel, the rotating screws convey and process it through controlled mechanical and thermal energy.

As the material travels toward the die, pressure and temperature change while ingredients are mixed and cooked. The process modifies starch and protein structures and creates the viscoelastic mass required for kibble formation.

At the die outlet, the pressure drops rapidly. Moisture flashes from the product, contributing to expansion. A cutting system then controls the length of the individual kibble pieces.

Die geometry, cutter speed, formula, process moisture, specific mechanical energy, and pressure all influence the final product. Changing from an 8 mm product to a 12 mm product therefore involves more than simply exchanging one round die opening for another.

Kibble Size and Shape for the Initial Product Range

The manufacturer planned several dry dog food products with kibble dimensions generally between approximately 8 and 12 mm.

The manufacturer does not define a dog food only by the animal’s weight and one die diameter. Kibble thickness, length, shape, bulk density, hardness, expansion, and texture are developed together according to the target product.

Different dies and cutting settings make it possible to create additional shapes as the brand develops new SKUs.

Drying Is Part of Extruded Dog Food Production

Kibble leaving an extruder is not a finished shelf-stable product.

It still contains substantial process moisture and must be dried under controlled conditions. Drying therefore has to be sized around both the extrusion capacity and the characteristics of the kibble.

The Colorado project was designed around finished dry kibble moisture appropriate for stable storage, but the plant’s quality system evaluates product safety and stability through controlled processing and product testing rather than relying on moisture percentage alone.

For commercial pet food, water activity is particularly important. Two products with similar moisture percentages can have different storage behavior, so moisture and water-activity targets need to be validated for the actual formulation and packaging system.

Post-Drying Fat and Palatant Application

After drying, the kibble enters the coating stage.

This is where selected fats, oils, palatants, or other post-extrusion components can be applied according to the formulation. Separating part of the fat addition from the extrusion stage gives the manufacturer more freedom to optimize both extrusion performance and final product characteristics.

Uniform coating matters because inconsistent application can create differences in palatability and nutritional composition between kibble batches.

After coating, the product is cooled to an appropriate temperature before storage and packaging.

Food Safety Was a Major Part of the US Project

For a customer manufacturing pet food commercially in the United States, buying an extruder is only one part of establishing a compliant operation.

The production facility needs an appropriate food-safety system covering ingredient receiving, supplier controls, process controls, sanitation, traceability, preventive controls, storage, finished-product testing, and recall preparedness as applicable to the operation.

The customer therefore incorporated the extruder into a broader manufacturing and quality-control program rather than treating extrusion itself as proof that the finished dog food is safe.

Process parameters such as temperature and residence time must be validated within the manufacturer’s actual food-safety plan and formulation. RICHI provides the equipment and process-engineering support, while the pet food producer remains responsible for its product formulation, regulatory compliance, process validation, and finished-product release procedures.

Electrical Configuration for the United States

The machine configuration was prepared for the electrical conditions of the customer’s Colorado facility.

For US industrial installations, voltage, frequency, motor configuration, control components, protection devices, cable sizing, and local electrical requirements need to be confirmed before manufacturing.

The customer’s project used a 60 Hz electrical configuration suitable for the site’s industrial power system.

Rather than assuming that every American plant uses exactly the same voltage arrangement, RICHI confirms the customer’s actual incoming supply and control requirements before finalizing the electrical design.

Why the Customer Did Not Buy a Used Dog Food Extruder

Used extrusion equipment initially appeared attractive because of the lower purchase price.

However, the customer was entering manufacturing for the first time. Unknown screw and barrel wear, obsolete controls, incomplete documentation, unavailable spare parts, and uncertain previous operating history represented additional risk.

For an established factory with experienced extrusion engineers, rebuilding a used machine can sometimes be economically reasonable.

For this project, the company preferred new equipment with a known configuration, new wear components, technical documentation, commissioning support, and spare-parts availability.

The decision was based on production risk rather than the assumption that used equipment is inherently unsuitable.

Installation in the Colorado Production Facility

The SPHS120×2 was shipped from Qingdao Port, China, to the United States and then transported to the customer’s Colorado facility.

Before shipment, interface drawings were supplied so the customer could prepare the installation area, utilities, access space, and connections to upstream and downstream equipment.

This was particularly important because an extruder cannot be positioned in isolation. The arrangement must consider the conditioner above or ahead of the machine, material feeding, steam and water connections, product discharge, dryer interface, operator access, maintenance clearance, and removal space for screws and wear components.

The installation layout therefore reserved considerably more working space than the physical footprint of the extruder itself.

Commissioning with the Customer’s Actual Recipes

Initial commissioning focused on obtaining stable extrusion rather than immediately pursuing maximum throughput.

The engineering team worked through feed rate, conditioner settings, water and steam addition, screw speed, cutter speed, die configuration, motor load, and finished-product response.

Operators evaluated kibble shape, expansion, bulk density, internal structure, surface condition, fines, drying behavior, and final moisture together.

Once a stable processing window was established for one formulation, the settings were documented as a starting recipe. Additional formulations were then commissioned separately because a process setting developed for one dog food should not automatically be copied to another.

Actual Production Is Scheduled around Demand, Not Maximum Machine Hours

A 1.5–2.0 T/H extruder does not mean a startup manufacturer should immediately run eight hours every day.

At 1.5 T/H, even four extrusion hours represent approximately six tonnes of product before accounting for startup, changeover, cleaning, and other operating factors. That can already be substantial for a new regional brand.

The Colorado customer therefore schedules production by SKU and sales requirement. Larger batches are produced for the principal adult formula, while smaller runs are scheduled for specialty products.

This reduces unnecessary finished-goods inventory and makes better use of the flexibility that motivated the company to choose a moderate-capacity twin-screw machine in the first place.

Changeover between Different Dog Food Products

Recipe changeover is more complicated than changing the die plate.

When switching products, operators have to consider residual material in the feeder, conditioner, barrel, die, dryer, coating system, conveyors, and other contact surfaces. The required cleaning procedure depends on the ingredients and the manufacturer’s food-safety and labeling program.

This becomes particularly important when formulas contain different animal proteins or ingredients that require segregation under the company’s quality system.

For that reason, the customer groups production runs where practical instead of continuously alternating between formulas.

Wear Parts and Preventive Maintenance

Extrusion places substantial mechanical and thermal loads on screws, barrel components, dies, cutter assemblies, bearings, seals, and transmission components.

The customer therefore purchased critical wear and spare parts together with the machine and established an inspection schedule from startup.

Screw and barrel wear is monitored because gradual wear can affect pressure development, cooking behavior, throughput, and product consistency long before the machine experiences an obvious mechanical failure.

Operators were also trained to distinguish between normal wear and process problems. An unstable kibble is not automatically evidence that the screw is worn; raw-material variation, conditioning, moisture, die condition, or feeding instability may produce similar symptoms.

Training for a First-Time Pet Food Manufacturer

Because the company had pet-industry experience but limited extrusion-manufacturing experience, operator training was an important part of the project.

Training covered startup and shutdown sequences, feeder control, conditioning, extrusion adjustment, die and cutter changes, cleaning, lubrication, routine inspection, abnormal-load response, and troubleshooting.

More importantly, operators learned how individual process adjustments interact.

For example, an expansion problem should not automatically be corrected by increasing temperature. Formula moisture, starch characteristics, fat level, screw configuration, feed rate, die restriction, and mechanical energy may all contribute.

Customer Feedback after Entering Commercial Production

“We needed an extruder that gave us room to develop products without starting with industrial-scale capacity that we could not immediately use. The biggest learning curve was not operating the machine itself; it was understanding how each recipe behaves differently during extrusion. Once our team started treating feed rate, moisture, screw settings, die configuration, drying, and coating as one process, our production became much more consistent.”

The company has continued developing additional products around the same extrusion platform rather than immediately replacing the machine with a substantially larger unit.

Future capacity expansion will be evaluated against sales volume and the capacities of the dryer, coating system, material handling, packaging equipment, utilities, and warehouse. Increasing extruder motor power alone would not automatically double the output of the complete manufacturing system.

Can the 90 kW Extruder Simply Be Upgraded to Double Capacity?

Not necessarily.

Extrusion capacity is determined by the complete mechanical and process configuration, not just the nameplate power of the main motor. Screw geometry, gearbox rating, barrel configuration, feeding capacity, conditioner, die, formula, and downstream equipment all impose limits.

Therefore, a future requirement of 3–4 T/H would be evaluated as a new engineering condition. Depending on the required products, modifying selected components may be possible, but in other cases a larger extruder or second production unit would be the more technically appropriate solution.

This prevents a startup customer from making expansion plans based on the misleading assumption that replacing a 90 kW motor with a 110 kW motor automatically creates twice the production capacity.

What US Buyers Should Check When Looking for a Dog Food Machine for Sale

For an American pet food manufacturer, extruder selection should begin with the products rather than the equipment catalog.

• Target output and realistic operating hours per day
• Dry kibble formulas and major starch/protein sources
• Fresh-meat or high-fat inclusion requirements, if applicable
• Required kibble dimensions, shapes, density, and texture
• Upstream grinding, dosing, and mixing equipment already available
• Steam, water, electrical, and compressed-air conditions at the factory
• Required dryer capacity and drying control
• Fat and palatant coating requirements
• Cooling, conveying, screening, and packaging arrangements
• US food-safety, sanitation, electrical, and plant-design requirements applicable to the operation

Providing these details allows RICHI to determine whether a standalone SPHS extruder is sufficient or whether the customer actually requires additional process equipment.

Dog Food Machine for Sale in United States for Growing Pet Food Brands

This dog food machine for sale in United States project shows why equipment selection for a startup pet food manufacturer should focus on usable production capacity rather than the largest possible nameplate output.

The Colorado customer selected one SPHS120×2 twin-screw extruder with a 90 kW project configuration and approximately 1.5–2.0 T/H target throughput. It provides the flexibility needed to develop several dry dog food products while remaining appropriate for the company’s initial commercial scale.

Just as importantly, the extruder is treated as one part of the manufacturing process. Grinding, accurate formulation, mixing, pre-conditioning, extrusion, drying, coating, cooling, sanitation, process validation, quality control, and packaging all determine whether the finished kibble can become a consistent commercial product.

For US customers searching for a dog food machine for sale, RICHI Machinery can configure the extrusion system according to actual formula characteristics, required output, kibble specifications, existing equipment, plant utilities, available space, and future expansion plan. This allows the customer to invest in the production capacity it can use today while designing the surrounding system around realistic growth rather than unsupported capacity assumptions.
