7. Process Flow During Operation

Flow chart of feed pellet production line

Brief description of process flow

A. Pellet production process

(1) Raw material receiving and cleaning section: the raw materials that do not need to be crushed are input from the auxiliary feed port, and the debris and bulk materials are removed through the fence, and then transported through the conveyor and elevator to the primary cleaning screen to remove the ropes and larger pieces. The raw materials enter the magnetic separator to remove the metal debris, and then enter the batching warehouse, waiting for the batching, and the dust generated by the feeding enters the bag dust removal system for negative pressure dust removal. The raw materials that need to be crushed pass through the fence to remove the debris, and are sent to the primary cleaning screen by the hoist to remove the ropes, labels and other debris, and then the iron impurities are removed by the permanent magnet cylinder and then enter the warehouse to be crushed.

(2) Crushing section: the raw materials after magnetic separation enter the crusher, and the screens are selected according to the requirements of different product crushing fineness. The material first enters the feeding auger, and the feeding speed of the feeding auger is controlled by the inverter. The material passes through the feeding auger and enters the crusher for high-speed crushing. This process will generate a lot of heat and dust. This process uses a pulse dust removal system and adopts the negative pressure generated by a high-speed fan to make the crushed materials quickly pass through the screen of the crusher, which solves the heat and dust problems generated by crushing. The crushed materials pass through conveyors and elevators to the warehouse for ingredients.

(3) Batching and mixing section: The crushed materials and the raw materials that do not need to be crushed are sent to the batching process together. The batching adopts the automatic control system to carry out precision batching according to two proportions, and the liquid adding system adds soybean oil to the batching. The prepared material enters the granulating section through the conveyor and elevator.

(4) Granulation section: The materials from the mixing section are heated to 85°C by high-temperature steam for gelatinization, and then enter the granulator for granulation. The prepared teaching trough material particles enter the countercurrent cooling tower for exhaust air cooling, and the cooled particles enter the conveyor and elevator to the finished product warehouse.

(5) Finished product packing section: an electronic packing scale is installed under the finished product warehouse, and the packing scale will automatically quantify the packaging according to the adjusted and set amount, and then the bag mouth will be sewn by the sewing machine and automatically transported to the stacker to complete the processing process.

B. Production process of nursery material

The production process of nursery material is basically similar to that of granular material. The main difference is that the expansion process is added after crushing, and steam is used for material expansion. It is transported to the puffed silo through the conveying equipment, passes through the puffing machine, cooler and pulverizer, and then sent to the mixing section through the conveying equipment.

C. Premix production process

The premix production process only includes the raw material receiving and cleaning, crushing and batching mixing sections, and does not include the granulation process.
