Process flow of feed processing equipment
The production process of a feed factory generally includes the following processes: raw material receiving and storage, cleaning (removal of impurities), crushing, batching, mixing, pelleting, cooling, crushing, grading, finished product packaging storage, and distribution.
Medium and large feed equipment production line technology
1. Raw material cleaning
Bulk raw corn and soybean meal are received; the cleaning process is all the operating units that pass the corn and soybean meal that has passed the inspection of the raw material inspector into the silo. In this process, the impurity in the raw material is firstly removed by impurity removal equipment and then transported to the silo by receiving equipment and demagnetization equipment as planned. Production line equipment includes receiving devices (such as unloading pits, platforms, etc.), conveying equipment, primary cleaning screens, and magnetic separation devices (such as permanent magnet cylinders, 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 of the raw material inspector and store them neatly in the warehouse. In the process of receiving goods, four points must be achieved: 1. Accurately count the quantity; 2. There is no quality problem with the raw materials; 3. The receiving path is correct; 4. The receiving environment is clean.
2. Batching 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 material is transported to the powder storage bin. The ingredients are weighed out from the silo, and these weighed raw materials enter the powder silo, and a small number of materials and premixes are directly weighed manually and put into the silo for mixing. The quality of the batching process directly affects the accuracy of the product batching.
3. Crushing process
The crushing process refers to sending the raw materials to be crushed in the silo 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 capacity of the process equipment, and it is also the process with the largest energy consumption in the production of powdery materials. Monitor and confirm the hammer, screen, current, noise, and crushing path at any time.
4. Mixing process
During the mixing process, various crushed raw materials are discharged into the mixer from the mixing chamber, and oil is added to the feed in the mixer through the liquid-adding system as required so that all components are mixed evenly to achieve the desired 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 delivery. When producing pellet feed, the mixed powder is sent to the silo for pelleting. In order to ensure the efficiency of the mixer, maintenance personnel must regularly check and repair the equipment, and regularly test the efficiency of the mixer.
5. Granulation process
The mixed material is sent to the compression chamber of the granulator after being tempered by magnetic separation from the granulation bin, compressed into granulated feed, cooled by the cooling tower, and sieved by the screening equipment to obtain standard granules. Magnetic separation equipment must be cleaned regularly to prevent iron impurities from damaging the granulator. When quenching and tempering, the steam volume should be adjusted according to the requirements of the granule variety, and the ring die (aperture, compression ratio, material, etc.) should be selected according to the quality requirements of the granule process. Particle temperature and humidity. According to the variety, indoor temperature and humidity, season, and other factors adjust the cooling tower to achieve qualified particle temperature and humidity.
6. Finished product packaging process
The feed is weighed by the packing scale from the finished product warehouse, put into the bag, and then the packer inserts the label and seals it, and then is transported to the warehouse by the transport vehicle for stacking.
