1. Raw material cleaning
Receipt of raw corn and soybean meal in bulk; the clean-up process is all operation 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 impurities in the raw materials are first removed by the impurity removal equipment, and then transported to the silo as planned by the receiving equipment and the demagnetization equipment. The 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 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 of the raw material inspectors and store them neatly in the warehouse. Four points should be done in the process of receiving goods: 1. Accurately count the quantity; 2. There is no quality problem in the raw materials; 3. The receiving path is correct; 4. The receiving environment is clean.
2. Ingredient 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 silo. The ingredients are weighed from the silo, these weighed raw materials enter the powder silo, a small amount of material and premix are added directly and manually weighed 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 pulverization process means that the raw materials to be pulverized in the silo are sent to the crusher to be pulverized 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 powdery materials. Monitor and confirm hammers, screens, currents, noise and crushing paths at all times.
4. Mixing process
During the mixing process, the crushed raw materials are discharged from the mixing bin into the mixer, and oil is added to the feed in the mixer through the liquid addition system as needed, so that the components are mixed evenly and the desired mixing effect is achieved. 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 leaving the factory. 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 check and repair the equipment, and regularly test the efficiency of the mixer.
5. Granulation process
The mixed material is quenched and tempered by magnetic separation from the granulation bin, and then sent to the compression chamber of the granulator, compressed into pellet feed, cooled by a cooling tower, and sieved by a screening equipment to obtain standard granules. Magnetic separation equipment must be cleaned regularly to prevent iron impurities from causing damage to the granulator. When quenching and tempering, the amount of steam should be adjusted according to the requirements of the particle variety, and the ring die (aperture, compression ratio, material, etc.) should be selected according to the requirements of the particle process quality. 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 from the finished product warehouse by a packaging scale, packed into packaging bags, and then labelled and sealed by a packer, and then transported to the warehouse by a transport vehicle for stacking.
