What is the technological process of grain processing machinery?

 　　China Win Tone Machinery shares the process flow of grain processing machinery as follows:

　　1. Raw grain removal: The purchased raw grain is sent to the specific gravity classifier through the hoist, and the weeds, stones, sand and other impurities contained in the raw grain are sorted out step by step under the action of specific gravity separation and wind selection. Get clean raw grains for use in the next process.

　　2. Raw grain cleaning: After removing impurities, the raw grain is sent into the washing machine by the elevator, and washed by the water flow in the washing machine to obtain clean refined grain.

　　3. Refined grain soaking: After cleaning, the refined grains are evenly spread on the feeding tray and loaded into the turnover car, and then put into a temperature-filled water tank for high-temperature soaking; set the temperature and time according to the variety of grains, pass After soaking for time, high temperature sterilization inactivates enzymes, and then takes out and drains the water, and transfers to the next process.

　　4. Steam puffing: The miscellaneous grains soaked at high temperature are loaded into the steam box through the turnover truck, and the miscellaneous grains are modified by curing and puffing at high temperature and high pressure for a period of time according to the different set temperature and time of the miscellaneous grains.

　　5. Refined grain drying: After the miscellaneous grains are modified by steam puffing, they are manually fed into the drying box by the turnover truck through the feeding system of the miscellaneous grain dryer for rapid drying at low temperature. The miscellaneous grains are transferred layer by layer by the conveyor belt in the drying box; the clean hot air heated and filtered by the steam heat exchanger penetrates the miscellaneous grains material layer by layer, and the moisture in the material is rapidly heated by the hot air to form saturated steam, which is carried out of the box with the airflow and complete the drying process. During the drying process of materials, because the low-temperature hot air and materials run in reverse and vertical direction, it conforms to the drying mechanism of materials and ensures the original flavor and drying consistency of the grains. The dried raw grain is sent out of the box by the conveyor belt into the cooler. The conveyor belt in the drying box is a chain-driven stainless steel mesh belt. The speed of the conveyor belt and the temperature of the hot air in the box can be adjusted. The temperature and speed can be set to suit the drying requirements of different materials, which expands the scope of application.

　　6. Cooling: After the raw grain comes out of the drying box, the temperature is high. In order to stabilize the moisture and prevent moisture regain, it must be cooled to room temperature in time and quickly, so that it can be stored. This process is completed by a cooler, which is composed of a material conveyor belt and a cooling fan. The speed of the conveyor belt can be adjusted according to the different properties of the material and the size of the output.

　　7. Grinding: After drying and cooling, the miscellaneous grains are sent into the storage tank by the elevator; and then flow from the discharge port at the lower end of the storage tank to the pulverizer body for the pulverization process. The miscellaneous grains entering the pulverizer are sucked into the machine by negative pressure, and the feeding amount can be adjusted in time according to the particle size and output requirements of the material; pressure suction into the storage tank.

　　8. Proportional powder mixing: The multigrain flour is stored in different storage tanks. According to the requirements of the food formula, through the program setting of the computer control screen, the feeding system of the storage tank is opened respectively, and the powder is measured and mixed according to the proportion; The machine is evenly mixed into the required product. The mixed product is sent to the storage tank by the elevator.

　　9. Microwave sterilization: The multigrain flour must be microwave sterilized after being mixed with the proportion of powder, and then packaged. Microwave sterilization is automatically completed by microwave sterilization equipment, mainly to kill some harmful microorganisms carried by grain flour during processing, so that people can eat immediately in the future.

　　10. Metering and packaging: The sterilized grain flour should be packaged in time; the packaging is metered and packaged by a computerized packaging scale - the whole process: the integrated operation of feeding, metering, bagging and packaging. The packaging bag requires sealed packaging, and should have moisture-proof and aseptic packaging measures.

　　11. Product warehousing (or leaving the factory): The products that have passed the test are packaged and put into the warehouse or put on the market directly.
