Description

[0002] Rice, also known as paddy, is one of the main foods processed from rice grains. It is an important part of the human diet and is widely used all over the world. Rice is the main part of rice after husking, and is obtained through processes such as husking, bran removal and whitening. Rice comes from rice plants and is mainly grown in Asia, Africa and America. During the rice processing process, a layer of bran (i.e. rice husk) adheres to the surface of the rice grains and needs to be completely removed. The multi-stage bran screening device can effectively remove the bran layer on the surface of the rice grains through a continuous screening process, ensuring that the processed rice is clean and free of impurities.
