Flowchart of chicken feed production line:

1. Raw material cleaning

Receive bulk raw material corn and soybean meal; the cleaning process is to pass the corn and soybean meal that passed the inspection by the raw material inspector into all the operation units of the silo. In this process, the impurities in the raw materials are first removed by impurity removal equipment, and then transported to the silo according to the plan through the receiving equipment and 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 by the raw material inspector and store them neatly in the warehouse. Four points must be taken in the receiving process: 1. Accurately count the quantity; 2. The raw materials have no quality problems; 3. The receiving route 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. In the medium amount, these high-quality raw materials enter the powder silo, add a small amount of feed and premix, and mix directly in the raw material silo after manual weighing. 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 pulverized into powder, and then sent to the silo to be mixed by a conveyor for 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 powdered materials. Monitor and confirm the hammer, sieve, current, noise and crushing path at any time.

4. Mixing process

During the mixing process, the crushed various raw materials are discharged from the mixing bin into the mixer, and grease is added to the feed in the mixer through the liquid adding system as needed to make the components mix uniformly and 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 leaving the factory. In the production of 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

After being subjected to magnetic separation and conditioning, the mixed materials are sent to the compression chamber of the granulator to be compressed into granular feed, cooled by the cooling tower, and sieved by the screening equipment to obtain standard granules. The magnetic separation equipment must be cleaned regularly to prevent iron impurities from damaging the granulator. During quenching and tempering, the amount of steam should be adjusted according to the requirements of particle varieties, and the ring die (aperture, compression ratio, material, etc.) should be selected according to the requirements of particle process quality. When cooling, the cooling tower should be adjusted according to factors such as variety, indoor temperature and humidity, and seasons to achieve a qualified level. Particle temperature and humidity. Adjust the cooling tower to achieve qualified particle temperature and humidity according to the variety, indoor temperature and humidity, season and other factors.

6. Finished product packaging process

The feed is weighed from the finished product warehouse by a packaging scale, put into the packaging bag, and then the label is inserted and sealed by the packer, and then transported to the warehouse by the transport truck for stacking.
