Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of wheat seed cultivation, especially to a wheat seed cultivation air separation device. BACKGROUND

[0002] Wheat is the general term for plants of the genus triticum, and the representative species is triticum aestivum, which is a kind of cereal crop widely planted all over the world. The fruit of wheat is one of the staple foods of mankind. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. After fermentation, it can be used to make beer, alcohol, white wine (such as vodka), or biomass fuel. After molting, the wheat seeds need to be air separated to remove impurities such as chaff mixed in the wheat.

[0003] Publication No. CN218902675U discloses a wheat seed cultivation air separation device, which comprises an air separation box. The top of the air separation box is provided with a feeding mechanism. The inside of the air separation box is provided with a plurality of collection bins.
