Description

Screening device convenient for impurity removal

Technical Field

The utility model relates to the technical field of rice screening, in particular to a screening device convenient for impurity removal.

Background

In the rice processing process, the sizes of the processed rice particles are not completely the same due to various reasons, a part of the processed rice particles are larger, a part of the processed rice particles are smaller, and certain broken rice and impurities exist, but in the selling process, the price of the large-grain rice is completely different from that of the small-grain rice, and if the sizes of the sold rice particles are uneven, the price of the rice is seriously influenced, so that in order to improve the commercial value of products, the rice with higher quality is obtained, and when the rice is sold, the rice is required to be classified and screened.

The publication number is: the conventional rice screening machine proposed in CN209810667U can only process the single process of classifying rice or removing impurities, cannot perform impurity removal classification treatment once in multiple processes, cannot meet the requirement of large-batch continuous screening, and meanwhile, the conventional rice screening machine has low screening efficiency and unsatisfactory screening effect, so that the novel rice screening machine is required.

In combination with the above, the utility model mainly solves the problems as follows: 1. the rice particles are uneven in size, the screening efficiency is low, and the discharging is inconvenient; 2. the rice is not effectively removed, so that impurities such as rice hulls and the like are mixed with the rice, and the rice is not beneficial to sales.
