[0002] Food processing refers to the processing of grains, feed, vegetable oils and sugars, slaughtering and meat processing, aquatic products, and other foods such as vegetables, fruits, and nuts, directly using agricultural, forestry, animal husbandry, and fishery products as raw materials. It also includes the processing of potatoes, dehydrated vegetables, and canned vegetables. It is a type of agricultural product processing industry in a broad sense. Many food raw materials require tools for cleaning. Chinese patent (publication number: CN105901751A) discloses a large-scale fully automatic ginger cleaning machine, including a machine chamber, rollers, and roller brushes.
