Description

Technical Field

[0001] The utility model relates to the technical field of rice processing equipment, in particular to rice polishing equipment. Background Art

[0002] Rice, also known as rice, is a food made from rice grains after processes such as cleaning, husking, milling, and finished product sorting. During the processing of rice, in order to improve the quality of rice, rice polishing equipment is used to grind the rice, thereby facilitating the production and processing of rice and subsequent consumption.

[0003] In the Chinese patent with the announcement number CN217774201U, a rice polishing device is disclosed. The patent sets a filter plate inside the box body, and uses the filter holes on the surface of the filter plate to filter the broken rice grains and impurities in the rice grains after polishing. The full rice grains will remain on the surface of the filter plate for manual consumption, which can effectively improve the quality of the polished rice grains, solve the problem that some rice grain conveying and polishing machines do not have the function of filtering the polished rice grains, and use the second motor to drive the first brush on the surface of the rotating plate to rotate on the surface of the filter plate during the rice grain filtering process, which can avoid the clogging of the filter holes and improve the filtration efficiency; however, the above-mentioned rice polishing device drives the first brush to clean the filter plate by the second motor. After long-term use, rice will be accumulated in a ring shape around the brush. However, the accumulated rice is easy to clog the filter holes, thereby affecting the filtering effect and reducing the quality of the rice after filtration. Therefore, we propose a rice polishing device. Utility Model Content
