[0002] Rice, also known as rice, is a product obtained after a series of processing steps such as husking and peeling of rice grains. According to different growing environments and characteristics, rice can be divided into three types: indica rice, japonica rice and glutinous rice. When producing and processing rice, screening devices are needed to filter out impurities, stones, bran, etc. contained in the rice.

[0003] After searching, the patent number is CN220027679U, and the name is a utility model of a rice screening device, including a screening barrel. Through research and analysis, it is found that although the advantage of avoiding clogging during screening of the drum screen is found, the following disadvantages still exist to a certain extent.

[0004] For example, because it does not have a good screening effect when in use, multiple screening cannot be performed during screening, so that impurities in the rice cannot be fully screened out, reducing the effect of rice screening, and it does not have the function of absorbing dust during screening, so during screening, the dust will float and cannot be absorbed. After the rice is screened, the dust will also be adsorbed on the surface of the rice, affecting the quality of the rice after screening. In order to solve the above technical problems, we have designed a rice screening device. Utility Model Content
