3-4T/H Soybean Dregs Cat Litter Extruder in Italy

Why The Customer Chose Soybean Dregs As The Main Raw Material

Italy has a well-developed food manufacturing industry, including tofu processing, soy beverage production, vegetable protein ingredients, and livestock nutrition sectors. These industries generate large quantities of soybean dregs, also called okara, every year.

Previously, much of this material was sold cheaply for low-grade feed applications or organic composting. However, the customer recognized that soybean dregs still contain natural fiber and plant protein structures suitable for biodegradable cat litter production.

The raw materials used in this soybean dregs cat litter extruder in Italy project mainly included:

• Fresh soybean dregs from soy milk processing plants
• Corn starch powder
• Pea fiber
• Guar gum binder
• Small amounts of natural deodorizing additives

The final product produced by the customer was a 2.5-3mm tofu cat litter pellet designed for premium indoor cat owners. The pellets were marketed as flushable, fast water-absorbing, low tracking, and almost dust-free.

Compared with traditional bentonite litter, the customer believed soybean-based cat litter had stronger long-term growth potential in Italy because consumers were becoming more concerned about sustainability and indoor air quality.

Background Of The Customer’s Existing Workshop

Before purchasing this soybean dregs cat litter extruder in Italy, the customer already operated a small raw material mixing and packaging workshop near Milan. The facility initially imported finished tofu cat litter granules and only handled repackaging for local retail channels.

However, rising freight costs and unstable international supply chains pushed the customer to begin partial local production. At first, the company experimented with a small flat die pellet machine purchased locally, but several operational problems quickly appeared.

The previous equipment could not maintain stable pellet density when processing sticky soybean mixtures. Some pellets cracked after drying, while others became too soft after absorbing moisture during storage.

The customer also found that ordinary feed pellet machines were difficult to clean thoroughly, especially when switching between different plant fiber formulas. Since pet products require cleaner production standards than ordinary biomass fuel pellets, the customer started searching specifically for a professional soybean dregs cat litter pellet machine instead of modifying feed equipment repeatedly.

RICHI Machinery later proposed a ring die cat litter extruder equipped with a conditioner system specially designed for plant-based cat litter formulas.

Selected Equipment Configuration

After evaluating the customer’s daily output requirements, available workshop space, local electricity conditions, and target export demand, the following equipment model was selected.

Equipment Model: MSZLH320 Cat Litter Extruder

This model provided enough capacity for medium-scale commercial production while remaining flexible for formula adjustments and future product diversification.

The customer selected a conditioner-equipped model because soybean dregs require more stable moisture and temperature adjustment before extrusion. This configuration significantly improved pellet smoothness and reduced cracking after cooling.

Why A Ring Die Cat Litter Extruder Was Necessary

One interesting aspect of this project was that the customer originally considered purchasing a smaller biomass pellet machine. However, after detailed technical discussions, it became clear that ordinary biomass pellet presses were not suitable for premium tofu cat litter production.

Soybean residue behaves differently from wood fiber or straw. The material contains more protein, finer fibers, and higher moisture sensitivity. Without proper conditioning before pelletizing, the granules can easily become unstable.

RICHI engineers therefore adjusted several key sections of the soybean dregs cat litter extruder in Italy system:

1. Modified conditioner paddle angles for softer material mixing
2. Customized compression ratio inside the ring die
3. Improved anti-stick internal structure
4. Enhanced feeder control for wet soybean mixtures
5. Optimized cutter structure for shorter tofu litter granules

These adjustments helped the customer achieve a more consistent cylindrical pellet shape while maintaining low dust content.

Application Of The Finished Cat Litter Pellets

The final cat litter product produced by this soybean dregs cat litter extruder in Italy project targeted urban pet owners, especially apartment households where odor control and dust reduction are major concerns.

The finished pellets offered several important characteristics:

Fast liquid absorption performance

Natural plant-based odor control

Low dust generation during pouring

Flushable structure suitable for modern pet hygiene products

Lightweight packaging advantages for e-commerce sales

The customer mainly sold the products through pet stores, online retail platforms, and regional pet product distributors across Italy and neighboring European countries.

Expansion Potential Beyond Cat Litter Production

One major reason the customer selected this ring die cat litter extruder machine was equipment versatility. Although the current project focused on tofu cat litter pellets, the same machine can also process several other biomass and plant-based materials with relatively small adjustments.

In Italy, agricultural and food-processing by-products are widely available, including sunflower husk, rice husk, olive pomace fiber, wood sawdust, and cereal bran residues.

With different ring dies and formulas, this same cat litter pellet machine can also produce:

• Biomass fuel pellets
• Organic fertilizer granules
• Animal bedding pellets
• Plant fiber absorbent pellets
• Feed additive granules
• Wood cat litter pellets

This flexibility was especially important for the customer because seasonal soybean raw material supply sometimes fluctuates. The ability to process alternative plant fibers gives the workshop more long-term production stability.

Why The Customer Trusted RICHI Machinery

Before confirming the order, the customer compared several European and Asian equipment suppliers. What finally convinced the client was not simply machine pricing, but the detailed technical communication provided during the project planning stage.

RICHI engineers spent considerable time discussing:

Raw material moisture variation

Particle size consistency

Pellet density requirements

Drying behavior after extrusion

European packaging preferences

Dust control expectations for retail pet products

The customer also appreciated that RICHI did not recommend oversized equipment unnecessarily. Instead, the proposed model matched the actual operational stage of the business.

This practical approach helped establish strong confidence before production even started.

Shipping Details For The Project

The soybean dregs cat litter extruder in Italy was shipped from Qingdao Port.

The destination port for this project was:

Port of Genoa

Because Genoa is one of Italy’s most important industrial import ports, it provided suitable handling conditions for heavy pelletizing equipment and auxiliary components.

Installation And Commissioning Experience

Once the equipment arrived in Italy, installation progressed relatively smoothly because the customer had already prepared electrical systems, material storage areas, and ventilation upgrades inside the workshop.

RICHI provided:

• Equipment layout drawings
• Installation guidance
• Ring die selection recommendations
• Raw material formula suggestions
• Operator training support
• Pellet adjustment guidance
• Maintenance scheduling assistance

During commissioning, several soybean formulas were tested to determine the ideal starch ratio and moisture balance. Engineers adjusted the conditioner retention time multiple times before achieving the desired pellet hardness and absorption performance.

The customer later mentioned that these startup adjustments were extremely important because tofu cat litter production is much more sensitive than ordinary biomass pellet processing.

Customer Feedback After Production Stabilized

Several months after startup, the customer reported that pellet consistency improved significantly compared with the earlier flat die equipment.

The client particularly highlighted three operational improvements:

More uniform pellet size during continuous production

Lower dust levels after packaging and transportation

Improved stability when processing mixed soybean formulas

The customer also appreciated that cleaning and maintenance became easier than expected, especially when changing between scented and unscented cat litter products.

According to follow-up discussions, the company has already started planning additional product variations using natural herbal additives for premium pet markets.
