[0002] Rice is the finished product made from rice grains through various processes, including cleaning, husking, milling, and finishing. The rice germ and aleurone layer contain nearly 64% of rice's nutrients and over 90% of the nutrients required by the human body. It is a staple food for people in most parts of China. Rice processing involves removing the husk (glume) and cortex (bran). A rice grain consists of the husk, cortex, germ, and endosperm.
[0003] When processing the hulled rice, it needs to be screened. During the rice processing process, a large amount of dust will adhere to the outer surface of the rice. When the rice is screened, the dust on the rice will float up, increasing the dust in the air. Excessive dust in the air will damage the screening equipment, and the rice must be dusted after screening.
[0004] To this end, we propose a dust-free screening mechanism for rice production. Utility Model Content
