Application: widely used for mineral cat litter, plant-based cat litter, mixed cat litter, etc.
Cat litter production line is an industrial manufacturing system specially used for producing cat litter products. Through a series of continuous production processes and mechanical equipment, raw materials are processed into finished cat litter products that meet market demand. The production line is usually composed of raw material pretreatment equipment, molding equipment, drying equipment, screening equipment, packaging equipment, etc. The raw material pretreatment equipment is responsible for crushing and stirring various raw materials such as bentonite, sawdust, tofu raw materials, etc.; the molding equipment processes the processed raw materials into specific shapes, such as extruding into strips, balls, etc.; the drying equipment removes moisture from the cat litter through heating devices such as hot air furnaces to ensure product quality and storage period; the screening equipment screens out cat litter particles of unqualified size; finally, the packaging equipment quantitatively packages qualified products. Under the deployment of the automatic control system, the entire production line achieves efficient and stable production to meet the large demand for cat litter products in the pet products market.
1. Raw material ratio: Corn/cassava starch (40%-70%) is used as the basic water-absorbing material, pre-gelatinized starch (20%-40%) provides adhesion, guar gum (1%-2%) is used to enhance the particle strength, activated carbon (1%-3%) is added for deodorization, and mesoporous materials (2%-4%) are added to improve the odor adsorption efficiency.
2. Puffing process: The screw extruder is heated to 160°C to break the hydrogen bonds of the starch molecules and gelatinize to form a porous structure.The moisture content of the raw material is 15%-25%, the extrusion time is ≤5 seconds, and the particle density is reduced by 30%-40% after puffing.
3. Granulation: The twin-screw extruder is formed through a mold, and the particle diameter is 2-6mm and the length is 5-20mm. The pre-gelatinized starch gels when it encounters water, and forms a stable network structure after cooling.
4. Drying and dehydration: The drum dryer is suitable for large-scale drying of various cat litter raw materials such as bentonite, potato residue, sawdust, etc., and the moisture content is reduced from 16% to below 8%. Microwave drying is mostly suitable for tofu cat litter, which has a sterilization function and can extend the shelf life by more than 30%.
5. Screening and cooling: The vibrating screen removes dust <0.15mm (concentration ≤5mg/m³), and the proportion of qualified particles is ≥95%. Naturally cool to room temperature to prevent starch particles from absorbing moisture and rehydrating.
6. Packaging, storage and transportation: Sealed packaging, automatic packaging machine is filled with nitrogen to prevent moisture, and the water activity (Aw) is controlled below 0.65.
