Description

Technical Field

[0001] This application relates to the field of white rice screening. Specifically, it relates to a white rice grading sieve with impurity removal function. Background Art

[0002] Due to the presence of rice husks in white rice, and when hulling rice, white rice may break to produce broken rice. However, when screening white rice currently, only the rice husks in the white rice can be removed, and it is impossible to effectively separate the whole rice and broken rice. As a result, personnel need to screen the screened white rice again to separate the broken rice, increasing the labor burden of the personnel. How to invent a white rice grading and selecting sieve with an impurity removal structure to improve these problems.
