[0002] During the production process, rice will be mixed with a lot of stones, and the rice needs to be de-stoned. Common de-stone and de-impurity devices generally remove impurities inside the rice by adding a filter screen inside the de-impurity box and driving it to vibrate through a vibration motor. For example, the authorized patent CN209406825U, a vibrating impurity and de-stone selection device for rice processing, includes a box body, a vibrating screen and a fan to remove impurities in the rice and reduce dust during the screening process. The structure of the single filter screen added in this way can only perform a single screening of impurities that are larger or smaller than the size of the rice.
