Tofu Cat Litter Manufacturing Plant in Thailand

RICHI MACHINERY

Project Background and Client Profile

The client is a Thai entrepreneur with a background in agricultural trading and processing. Having observed the rising trend in pet ownership and the increasing demand for natural pet care products in Southeast Asia, the client recognized the potential of establishing a tofu cat litter manufacturing plant in Thailand. The decision was further motivated by:

• The availability of soybean residue (okara) from local tofu and soy milk producers, which is often underutilized or discarded.
• Growing consumer awareness of the environmental impact of traditional clay-based and silica gel cat litters.
• Support from Thai government initiatives promoting value-added agricultural processing and SME development.

The project aims to produce 2,000 tons of tofu-based cat litter annually, equivalent to approximately 0.42 tons per hour based on 4,800 operational hours per year. The production line is designed to process a variety of natural ingredients into uniform, low-dust, and highly absorbent cat litter pellets, with typical pellet sizes ranging from 2–4 mm in diameter and 6–12 mm in length.

Raw Materials and Formulation

Thailand is one of the leading agricultural producers in Southeast Asia, with significant outputs of soybeans, corn, and cassava. This tofu cat litter manufacturing plant in Thailand capitalizes on these resources, utilizing a blend of natural, biodegradable materials to produce a high-performance product.

The primary raw material is soybean residue (okara), a by-product of tofu and soy milk production. This material is abundant, low-cost, and highly absorbent, making it an ideal base for cat litter. It is supplemented with corn starch, wheat flour, and corn flour, which act as natural binders to enhance pellet durability and clumping properties. Minor additions of bamboo fiber and calcium carbonate are included to adjust texture, density, and moisture control.

Below is the typical formulation used in this tofu cat litter production line in Thailand:

All raw materials are stored in a dedicated, dry area within the production facility to prevent moisture absorption and spoilage.

Production Process and Technology

The manufacturing process for this tofu cat litter manufacturing plant in Thailand is based on a dry extrusion and pelletizing system, specially designed for natural fiber-based materials. The entire process is semi-automated, ensuring consistent product quality while minimizing labor and energy costs.

Process Description:

1. Weighing and Pre-mixing
   Raw materials are accurately weighed according to the formulation and transferred to a pre-mixing hopper. This step is carried out in an enclosed system to minimize dust generation.
2. Mixing and Conditioning
   The dry ingredients are fed into a high-speed mixer (SLHY 2.0 type) where water is added to achieve a uniform moisture content of approximately 25–30%. This conditioning step is critical for proper gelatinization and binding during pelletizing.
3. Pelletizing
   The conditioned material is conveyed to a ring die pellet mill (SZLH 350 model), where it is compressed through 2–4 mm dies to form uniform cylindrical pellets. The mechanical pressure and friction generate heat, which partially cooks the starch, improving binding and digestibility (if used in edible applications).
4. Cooling and Drying
   The hot, soft pellets are discharged into a counter-flow cooler (SKLN 2.5) to reduce temperature and moisture surface content. They are then passed through a microwave drying system to achieve a final moisture content of below 10%, ensuring shelf stability and preventing mold growth.
5. Screening and Packaging
   The dried pellets are screened using a rotary sifter (SPJH 110×2) to remove fines and oversized particles. The on-spec product is conveyed to an automated weighing and packaging line, where it is packed into 5 kg or 10 kg bags for distribution.

Throughout the process, dust control is maintained using cyclones and pulse-jet bag filters, with all emissions compliant with Thai environmental standards.

Utility Consumption and Environmental Management

Utility requirements for this tofu cat litter manufacturing plant in Thailand are relatively modest, in line with its small to medium scale of operation.

• Electricity: Total connected load is 120 kW, with an average consumption of 80 kW during operation. Power is supplied by the provincial grid, with a backup generator for critical processes.
• Water: Total daily water consumption is 2.23 m³, used primarily for:
  • Mixing and conditioning: 1.7 m³/day
  • Cooling system makeup: 0.05 m³/day
  • Staff amenities: 0.48 m³/day

Wastewater generation is minimal. Process water is fully absorbed into the product, and cooling water is recirculated. Sanitary wastewater is treated via a septic tank and soakaway pit, in compliance with local regulations.

Dust emissions are controlled using a cyclone and bag filter system, with a single 15-meter stack discharging clean air. Noise levels are managed through equipment enclosure and building insulation.
