Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a novel rice husking machine. Background Art

[0002] Food processing refers to the grain grinding, feed processing, aquatic product processing, and processing of vegetables, fruits, nuts and other foods directly using agriculture, forestry, animal husbandry and fishery products as raw materials, as well as potato, dehydrated vegetable processing, and canned vegetable processing. It is a type of broad agricultural product processing industry.

[0003] In the prior art, the rice needs to be manually poured into the rice husking device at a uniform speed and in a quantitative manner, otherwise the rice may be piled up and the rice husk loosening effect is also poor. In addition, the rice is only husked once by a blower after the husk loosening is completed, which may result in incomplete rice husking and some residues. Utility Model Content
