[0002] A rice mill is a type of grain processing machinery, which is used to remove the bran layer (cortex and germ) of grains and grind them into finished products (for example, various types of rice sold in supermarkets). An application number CN201910971522.9 has been retrieved, which is a grain rice mill. The invention proposes a technical solution in which the rice mill does not need to set up multiple rice milling chambers to grind the grains in sequence to achieve the whitening effect; and the volume of the box becomes smaller, and the rice mill does not need to occupy a large space to use, making the rice mill more flexible to use.
