[0002] Glutinous rice, also known as Jiangmi, is rich in carbohydrates, protein and various trace elements. It is a common ingredient for making snacks such as rice cakes and glutinous rice balls. It has rich nutritional value and various edible functions. It has rich nutritional value and various edible functions. Glutinous rice needs to be washed before grinding into powder.

[0003] Existing publication number CN109261505B discloses a glutinous rice cleaning and screening device for rice cake production, which adopts two counter-rotating cleaning motors. During the cleaning process, the glutinous rice will not sink directly to the bottom due to convection, thereby improving the cleaning efficiency.

[0004] The existing device also has the following deficiencies:
