[0002] Grain processing refers to the process of treating and transforming raw grains (such as cereals and legumes) through physical, chemical, and biological methods to produce edible foods or other products. The main steps in grain processing include cleaning, shelling, grinding, mixing, fermentation, baking, and drying. Common processed grain products include flour, rice, corn starch, tofu, and biscuits.

[0003] In the prior art, patent application number CN211678735U discloses a grain cleaning device with a dust removal device, comprising a box body, an inner cavity of the box body provided with a screening plate, the front and rear sides of the screening plate are respectively fixedly connected to two spring plates, the bottom of the spring plates are fixedly connected to the bottom of the inner cavity of the box body, and the top of the screening plate is fixedly connected to a fixed plate. The utility model drives the screening plate to vibrate by using a dual-axis motor and an eccentric swing block, and blows the dust in the inner cavity of the box body to the inner cavity of the filter box through the setting of a blower mechanism, thereby achieving a good dust removal effect. The grain cleaning device with a dust removal device solves the problem that most of the existing grain cleaning equipment only removes granular impurities in the grain, but cannot achieve a good dust removal effect for the fine dust in the grain, resulting in a large amount of fine dust remaining in the grain, which is not conducive to the later grain processing.
