[0002] Wheat is a general term for plants of the genus Triticeae. The representative species is common wheat, which is a grass plant and a cereal crop widely grown around the world. The caryopsis of wheat is one of the staple foods of humans. It can be ground into flour to make bread, steamed buns, biscuits, noodles and other foods. It can be fermented to make beer, alcohol, liquor (such as vodka), or biomass fuel. After molting, the wheat seeds need to be air-selected to remove impurities such as wheat husks mixed in the wheat. The existing wheat grading and air-selecting device generally uses a hot air blower to blow air to the wheat seeds, which can air-select the wheat seeds. However, the dust from the outside will also be blown into the interior of the air-selecting box along with the air, which aggravates the pollution of the wheat seeds, affects the dust removal efficiency of the dust removal mechanism, and reduces the air-selection effect. Improvements are needed.
