Description

Technical Field

[0002] Rice is a staple food extracted from paddy through a series of processing steps, including cleaning, dehulling, rice milling, and final finishing. After a large number of searches, the publication number is CN215784924U, which discloses a multifunctional rice processing and filtering device. Through the high-speed rotation of the fan blades, the device can blow the dust and rice bran of the rice just entering the funnel, thereby removing sundries from the rice to a certain extent.

[0003] However, in order to improve the filtering efficiency, the injection speed of rice is usually relatively fast. In this case, due to the relatively fast entry speed of rice, when blowing high-pressure air on the rice, if the rice feeding speed is greater than the air flow speed, it will be difficult to discharge the impurities in the rice. Similarly, when the rice feeding speed is lower than the air flow speed and the air flow speed is too large, the rice will be blown out from the funnel, resulting in waste of rice. Therefore, a rice processing and filtering device needs to be proposed to solve the above problems. Content of the Utility Model
