Medium and large feed processing machinery and equipment production line equipment and process flow

1. Raw material cleaning

Bulk raw materials corn and soybean meal are received; the cleaning process is to enter all operating units of the silo that have passed the inspection by the raw material inspector. In this process, impurities in the raw materials are first removed using impurity removal equipment, and then transported to the silo as planned through receiving equipment and demagnetization equipment. Production line equipment includes receiving devices (such as discharge pits, platforms, etc.), conveying equipment, primary cleaning screens, and magnetic separation devices (such as permanent magnet drums, permanent magnet drums, etc.). For the receipt of bagged raw materials, it means that the loading and unloading personnel unload the raw materials that have passed the inspection by the raw material inspector and store them neatly in the warehouse. Four points must be achieved during the receiving process: 1. Accurately count the quantity; 2. There are no quality problems with the raw materials; 3. The receiving path is correct; 4. The receiving environment is clean.

2. Ingredients process

The batching process is to weigh the raw materials in the batching bin from the feeder under each batching bin to the batching according to the formula requirements. After each raw material is weighed by the batching scale, the raw materials are transported to the powder storage bin. The ingredients are weighed out from the silo. These weighed raw materials enter the powder silo. A small amount of materials and premixes are added and directly weighed manually and then put into the silo for mixing. The quality of the batching process directly affects the accuracy of product batching.

3. Crushing process

The crushing process means that the raw materials to be crushed in the silo are sent to the crusher to be crushed into powder, and then sent to the silo to be mixed by the conveyor before use. The purpose of this process is to control the particle size of the material. The design efficiency of the crusher in this process determines the production capacity of the process equipment, and it is also the process with the largest energy consumption in the production of powdered materials. Monitor and confirm hammers, screens, current, noise and crushing paths at any time.

4. Mixing process

During the mixing process, various crushed raw materials are discharged from the mixing chamber into the mixer, and oil is added to the feed in the mixer through the liquid addition system as needed to mix the components evenly and achieve the required mixing effect. Uniformity. The material discharged from the mixer is the finished product, which is directly sent to the packaging process of the finished product for packaging and shipment. When producing pellet feed, the mixed powder is sent to the silo for granulation. In order to ensure the efficiency of the mixer, maintenance personnel must regularly inspect and repair the equipment and regularly test the efficiency of the mixer.

5. Granulation process

After the mixed materials are magnetically separated and conditioned from the granulation bin, they are sent to the compression chamber of the granulator, compressed into pellet feed, cooled by the cooling tower, and screened by screening equipment to obtain standard granules. Magnetic separation equipment must be cleaned regularly to prevent iron impurities from causing damage to the granulator. When conditioning, the amount of steam should be adjusted according to the requirements of the particle variety, and the ring mold (pore diameter, compression ratio, material, etc.) should be selected according to the particle process quality requirements. During cooling, the cooling tower should be adjusted according to the variety, indoor temperature and humidity, season and other factors to achieve qualified results. Particle temperature and humidity. Adjust the cooling tower according to factors such as variety, indoor temperature and humidity, season, etc. to achieve qualified particle temperature and humidity.

6. Finished product packaging process

The feed is weighed from the finished product warehouse through a packaging scale, put into packaging bags, and then the packer inserts the label and seals it, and then is transported to the warehouse by a transport truck for stacking.
