Description

Technical Field

[0001] The utility model belongs to the technical field of rice screening, in particular to a rice screening device for rice production. Background Art

[0002] Rice is a finished product made from paddy rice after processes such as cleaning, husking, milling, and finished product sorting. The bran screening process is to use suitable equipment, through appropriate process flow and proper operation methods, to remove various impurities mixed in the rice, so as to improve the quality of the finished rice product. During the production and processing of rice, due to the action of mechanical force, part of the rice will be broken into fine broken rice. If it is packaged directly, it will affect the quality of the rice. Therefore, it is necessary to screen the broken rice mixed in the rice.

[0003] The existing screening device has a slow screening speed and poor screening degree, so that the broken rice mixed in the rice cannot be completely screened out, resulting in the broken rice and the whole rice still being mixed together, resulting in poor appearance and lack of nutrition, which reduces the overall quality of the rice and affects the price of the rice.
