Description

Fan sieve for rice processing

Technical Field

The invention belongs to the technical field of agricultural product processing, and particularly relates to a fan sieve for rice processing.

Background

Rice is a finished product prepared by rice through the procedures of cleaning, hulling, milling, finishing and the like. The embryo and aleurone layers of the rice contain nearly 64 percent of rice nutrition and more than 90 percent of nutrient elements required by human bodies, and are main food for southern people. The rice contains about 75% of carbohydrate, 7% -8% of protein, 1.3% -1.8% of fat and rich B vitamins. The carbohydrate in the rice is mainly starch, the protein is mainly glutelin, and secondly gliadin and globulin, the biological value of the protein and the composition ratio of amino acid are higher than that of cereal crops such as wheat, barley, millet, corn and the like, the digestibility is 66.8-83.1%, and the carbohydrate is also one of the cereal proteins.

Rice is one of the indispensable important staple foods in the modern society, and the production and processing of the rice are directly related to the development of people.
