[0002] Grain refers to the general term for various plant seeds in cooking food, also known as "grain", which is rich in nutrients, mainly protein, vitamins, dietary fiber, fat, etc. my country is a large agricultural country, and food has a vital influence. After the grain is harvested, many impurities will be mixed in it, such as small stones, soil clods, weed clippings, etc., which will affect the purity and quality of the grain, which is not conducive to preservation and use

[0003] Since the grain will be mixed with tiny impurities such as dust and grass clippings, these impurities will fly into the air during screening, causing pollution to the working environment. The organic impurities in them may cause dust explosions. , it will also cause the grain to become hot, mildewed and deteriorated; after inorganic impurities enter the equipment, it will cause damage to the equipment and affect the normal production and use. impact, and thus cannot guarantee the purity and quality of food
