Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to rice processing dust removal equipment capable of preventing dust from overflowing. Background Art

[0002] Rice is a processed food made from rice grains (paddy), primarily composed of starch. It is a staple food in many countries and regions. Rice processing generally involves removing the husk of the rice grains to obtain brown rice, then removing the germ and outer bran to obtain polished rice. Finally, polishing the rice grains to smooth their surface, improving their appearance and quality. Dust removal is a crucial step in rice processing. This is primarily because dust, dirt, and other impurities may accumulate during harvesting and storage. These impurities must be removed during processing to ensure cleanliness and hygiene. Dust and other impurities can affect the appearance and taste of rice. Dust removal improves the overall quality of rice, making it more suitable for consumer demand. Dust and impurities can cause wear and clog processing equipment. Regular dust removal helps extend the life of equipment and maintain smooth processing. Dust removal also helps reduce the presence of bacteria and other harmful substances, ensuring the food safety of the rice. Effective dust removal can ensure rice quality and safety, improving consumer satisfaction.

[0003] Most of the existing rice dust removal methods are manual dust removal or dust removal through dust-raising fans, which often causes dust to escape to the outside, causing air pollution and easily causing physical harm to workers. In addition, if equipment is used for dust removal, most equipment requires multiple power equipment to be used in combination to achieve dust removal. This method of use is more energy-consuming and capital-intensive.
