Background

Rice (Rice), also known as Rice, is a food made from Rice through the processes of cleaning, hulling, milling and finishing. Rice is a major food for people in most of china. 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 protein contains less lysine and threonine, so it is not a complete protein and has a nutritive value comparable to that of animal protein. But the rice is more beneficial to losing weight compared with cooked wheaten food when being eaten in lunch and dinner. In southern areas of China, people generally eat rice as staple food, but in northern areas, there are great differences.

In the process of rice processing, filtering and screening are very important processes, and no matter shelling or rice quality screening is carried out, a large amount of dust can be generated in the screening process, so that the existing processing workshop can adopt a closed separating device for screening under the condition, but the screen used by the closed screening and filtering device is difficult to clean meshes, the machine needs to be stopped before cleaning, and then the equipment is disassembled, so that the normal production of the equipment is greatly influenced, and the equipment is very inconvenient, the importance of timing cleaning of the screen is very obvious, the effect and the efficiency of rice screening and filtering are ensured, and therefore the existing filtering device for rice processing cannot meet the use requirements of people in production and life.
