Humans have identified 22 types of rice, but the only one used in bulk trade is Oryza sativa. my country is one of the countries with the longest history of rice cultivation and the richest rice genetic resources. Ancient cultivated rice specimens unearthed from the Yuchanyan site in Shouyan Town, Dao County, Hunan Province, confirm that rice cultivation in China has a history of more than 14,000 years, making it the known origin of cultivated rice in the world.

[0003] With the advancement of science and technology, my country's grain output has gradually increased, especially the increase in rice output, which has solved the problem of food shortage in my country. Due to the increase in rice output, rice deep-processing products have gradually entered people's lives. When rice is shelled, in order to improve the shelling effect and prevent the shelled white rice from being mixed with impurities, it is necessary to first screen the impurities in the rice and separate the impurities from the rice. The existing rice impurity removal method is mainly through filtering through a filter mesh. A large amount of dust will be generated during the filtering process. If the dust cannot be removed in time, it will be absorbed by workers and will cause certain safety hazards to the body. Therefore, this application provides a dust removal rice screening device.
