[0002] Wheat is a general term for plants of the wheat family. It is a monocotyledonous plant and a grass plant widely grown throughout the world. The caryopsis 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 made into beer, alcohol, liquor (such as vodka), or biofuel. Wheat needs to be dusted after processing.
[0003] Existing dust removal equipment for wheat processing generally uses fans or screens to clean dust, impurities and shriveled wheat in wheat. However, the fan cannot blow away larger impurities in wheat, and the impurities will still fall into the wheat grains, which need to be removed later, which is troublesome, time-consuming and labor-intensive.
[0004] At the same time, the size of the sieve holes is fixed and cannot be adjusted. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0016] The sieve at the top filters the larger impurity particles in the wheat. After the larger impurity particles are filtered, the wheat falls onto the sieve at the bottom. The sieve at the bottom screens the smaller impurity particles and shriveled wheat in the wheat, so that the impurity particles and shriveled wheat fall to the lower end of the inner part of the box, thereby cleaning up various impurities in the wheat. At the same time, the hair dryer blows air into the box, and the exhaust fan draws the air flow in the box to make the air flow in the box circulate, thereby drawing out the dust raised during the screening process, thereby cleaning up the dust in the wheat.
[0017] When adjusting the size of the mesh holes of the screen, the screw rod cooperates with the slider to drive the mesh plate to move, so that the mesh holes of the mesh plate and the mesh holes are staggered, thereby reducing the distance between the mesh holes of the mesh plate and the mesh holes, thereby adjusting the size of the mesh holes of the screen.
