[0002] Rice is one of the staple foods of human beings. According to modern nutrition analysis, rice contains protein, fat, vitamin B1, A, E and various minerals. In terms of varieties, rice is divided into polished rice, indica rice and glutinous rice. During the rice processing, different varieties of rice, such as rice, need to be husked. After the rice is husked, the rice contains a lot of sand and husks. At this time, it is necessary to screen these sand and husks from the rice. Most of the current rice screening devices can only filter out large particles of impurities, resulting in a decrease in rice quality, and the screening efficiency is not high, which is inconvenient to screen rice varieties with different particle sizes.
