Description

Technical Field

[0001] The utility model specifically relates to a raw material cleaning device for wheat processing, belonging to the technical field of wheat raw material cleaning. Background Art

[0002] Wheat flour is flour processed from wheat, generally refers to flour after the bran is extracted. It is one of the staple foods of residents in northern my country. Wheat flour contains protein, starch, fat, vitamins and inorganic salts. Wheat flour can be used to make food with unique quality and flavor. When processing wheat into wheat flour, the wheat needs to be thoroughly cleaned. First, the impurities in the wheat are removed, and then the dust attached to the surface of the wheat is cleaned. Generally, a cleaning device is used to clean the wheat raw materials.

[0003] For example, announcement number CN217431777U discloses a raw material cleaning device for wheat flour processing, comprising a casing, a feed port at the upper end of the casing, a discharge port at one side of the casing, a screen inside the casing, a blower at one side of the upper end of the screen, a filter at the other side, a dust box at one end of the casing, the dust box is connected to the interior of the casing through the filter, and a material receiving bucket is provided at the lower end of the filter. The equipment can pre-treat wheat and reduce subsequent cleaning pressure. The stirring blades do not contact the wheat during water cleaning to avoid impact and breakage of the wheat. At the same time, water resources are recycled to save resources.

[0004] After the wheat is cleaned, the prior art simply opens a side opening and sets a guide block so that the wheat can flow out under the action of gravity, thereby realizing the unloading of the wheat raw materials. If the slope of the guide block is set too large in this unloading method, the wheat will easily gather at the lower part of the guide block, affecting the cleaning effect of the wheat raw materials. If the slope of the guide block is set too small, the wheat raw materials will flow out at a low speed during unloading, affecting the unloading efficiency. Utility Model Content
