Description

Screening and grading equipment for rice processing

Technical Field

The invention relates to the technical field of rice processing, in particular to screening and grading equipment for rice processing.

Background

The rice is one of the traditional staple foods in China and is also a main food for people in the south of China. Rice is the basic food for supplementing nutrients, contains protein, fat, vitamins and 11 minerals besides carbohydrate, and can provide comprehensive nutrition for human body. 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.

In the rice processing process, the processed rice has different particle sizes due to various reasons, some of the particles are larger, some of the particles are smaller, and a certain amount of dust is also present, but in the selling process, the selling prices of large-particle rice and small-particle rice are completely different, and if the grain sizes of the sold rice are uneven and even the dust is mixed in the grain sizes, the quality and the selling price of the rice are seriously reduced, so that in order to improve the commercial value of products, the rice with higher quality is obtained, and the large-particle rice and the small-particle rice are required to be screened at the end of the rice processing.

However, some rice is only left with empty shells due to the fact that the rice is damaged by worms and the like, and if the rice is only distinguished by particle sizes, grading cannot be well achieved, the quality of high-quality rice cannot be well improved.
