Tofu Cat Litter Processing Plant in Vietnam

RICHI MACHINERY

Project Background

Vietnam’s pet industry has grown steadily due to rising urbanization, increasing disposable income, and expanding e-commerce channels. Within this market, tofu cat litter has emerged as a preferred product for environmentally conscious cat owners.

The client’s decision to invest in this tofu cat litter processing plant in Vietnam was based on several strategic considerations:

1. Raw Material Accessibility: Vietnam produces large quantities of tofu dregs and corn flour, ensuring year-round availability at competitive costs.
2. Growing Market Demand: Urban households in major cities like Ho Chi Minh City and Hanoi are increasingly choosing biodegradable cat litter, valuing its safety, dust-free nature, and odor control.
3. Sustainability Advantage: Tofu cat litter is biodegradable and environmentally friendly, offering the client a competitive edge in the premium pet product segment.
4. Flexible Production: The plant’s medium scale allows for adaptable production scheduling to match seasonal demand.

Raw Materials

The raw material selection is crucial to ensuring the litter’s clumping ability, absorbency, and low dust emission. Materials are stored in climate-controlled warehouses to maintain quality throughout the year.

The primary raw materials are:

The typical mixing ratio is approximately 1:1 tofu dregs to corn flour, with additives blended according to batch-specific requirements. This ensures optimal texture, odor control, and pellet integrity.

Production Process

The tofu cat litter processing plant in Vietnam employs a mechanized continuous process, combining mechanical, thermal, and airflow treatments.

1. Mixing: Raw materials are proportionally fed into mixing tanks, with a controlled amount of water added. The mixing duration is 10–15 minutes for a homogeneous slurry.
2. Pelleting: The mixture is transported via elevators to cat litter pellet machine, forming uniform pellets (~3–4 mm).
3. Drying: Pellets are dried in an electric mesh belt dryer, with temperatures carefully controlled to reduce moisture to 8–10%. Drying cycles last about 30 minutes.
4. Cooling: Dried pellets are cooled to ambient temperature using air circulation to prevent condensation and maintain structural integrity.
5. Screening: Sieving removes fines and oversized pellets, which are recycled back into the pelleting process.
6. Packaging: Pellets are packed into bags (5–10 kg) via an automatic packaging machine.

The process incorporates dust collection systems with pulse jet bag filters and 15-meter exhaust stacks, ensuring compliance with environmental regulations. Low-noise equipment and vibration damping measures are used to minimize disturbances.
