The vertical emery roller rice mill is mainly used for the processing of corn, millet, sorghum and other grains in northern my country. It is widely used in small and medium grain processing plants and villages, especially the processed corn ballast is round and smooth, like pebbles, and has a good cooking taste.

　　

　　1. The structure of the vertical emery roll rice mill

　　

　　1. Feeding part: feed hopper and feed gate.

　　

　　2. Whitening part: grain fins, emery roller, chaff sieve, rice fins, adjusting handwheel, blocking knife, exit gate, rice outlet, etc. 3. The chaff removing part is composed of a pulley, a fan, a chaff remover, a wind regulating plate, a chaff outlet, etc. The chaff output efficiency is controlled by the air volume adjustment. The vertical emery roller rice mill is a fast and light milling model. The linear speed of the roller is generally between 10 and 15 m/s, and the average pressure of the material is below 5 kPa. When working, the raw material enters the milling chamber from the hopper, and under the grinding action of the high-speed rotation of the roller, the skin of the raw material is peeled off and continues to be whitened, and the ground particles are discharged out of the machine through the rice nozzle. Part of the husks and bran residues removed during the whitening process of the raw materials are discharged through the sieve on the periphery of the whitening chamber, and the remaining part is drawn off by the airflow after the grains are discharged from the whitening chamber. The two chaffs are discharged by the fan Send them out of the body together.

　　

　　The pressure in the milling chamber is small, and there is less broken rice produced, but the husks of the grains will be ground unevenly. According to specific needs, it is sometimes necessary to screen the large grains and then whiten them twice or three times until they are satisfied. .

　　

　　The grain whitening efficiency is determined by the blocking knife, the grain fins, the imported gate and the whitening chamber gap and the machine running speed. The specific operation can be based on the dry and wet conditions of the raw grain and the whitening requirements to determine the number of processing passes.
