Project Process Design Solution

Process flow of 10 t/h pet feed mill in China

1. Crushing: The raw materials such as fish meal, chicken meal, beef meal, soybean meal and corn are transported to the crusher through the bucket elevator, and the raw materials are crushed.
2. Ingredients mixing: The crushed raw materials enter different silos through the rotary feeder. According to the production process, different materials are automatically weighed and batched through the PLC batching scale and batching system, and added to the mixing batch according to the ratio requirements.
3. Extrusion: The mixed material enters the pet food extrusion machine, uses steam to heat and mature the conditioned material, and then extrudes, expands and granulates.
4. Drying: use the dryer to dry the formed material, and this process uses steam to indirectly provide heat for the feed dryer.
5. Oil spraying: the dried product is transported to the spraying machine, and sprayed with oil and flavor-enhancing materials.
6. Cooling and screening: the sprayed material is cooled, and this project uses cold air to cool the material; the cooled material is screened through a screen, and the material that does not meet the product requirements is transported to the pulverizer by the elevator for crushing reuse.
7. Finished product packaging: The finished product is packaged through a fully automatic packaging system, and the packaged product is stored in the finished product warehouse for sale.

Process flow of 1.5t/h cat litter production line

1. Extrusion: In this project, montmorillonite, zeolite, and bentonite are used as raw materials, which are transported to the extruder through a loading and unloading machine, and extruded into a columnar block with a diameter of about 5 cm.
2. Drying: The extruded mixture generally has a large water content. In order to reduce the water content, drying equipment is used to dry the extruded material to the rotary dryer through the conveyor belt for drying. The heat source is steam. , The water content of the raw material is reduced to about 11%.
3. Grinding: The dried material is conveyed to the Raymond Mill by a conveyor belt for grinding, and soda auxiliary materials are added at the same time. The Raymond Mill is equipped with a material inlet and a material outlet, and the finished material is blown up by the internal wind. There is a separator inside the Raymond mill, which can separate coarse and fine powder.
4. Pelletizing: The qualified powder produced by the Raymond mill feeding port is sent to the powder silo through a closed screw conveyor. During granulation, according to the output, it is transported to the cat litter pellet machine through another screw conveyor for further processing. Granulate.
5. Drying and screening: The pellets are dried in a drying furnace, and the dried products are screened by a fully enclosed multi-stage screening machine, and unqualified products are recycled for reuse.
6. Packaging: Qualified products enter the packaging line, which is automated equipment, and the packaged products enter the warehouse for storage.
