Abstract

The invention provides a rice screening device for rice processing with impurity removal and dust fall functions. The rice screening device comprises a processing box, the top and the bottom of the processing box are connected with a feeding port and a discharging port respectively, the outer wall of the processing box is connected with a motor, the output end of the motor is connected with a rotating shaft, the end, away from the motor, of the rotating shaft penetrates through the processing box and is connected with a rotating disc, and fan blades are connected to the outer wall of the rotating disc; and a supporting frame is connected to the inner wall of the processing box, a heating pipe is connected to the outer wall of the supporting frame, a dust opening is formed in the outer wallof the processing box, and the outer wall of the dust opening is connected with a dust falling mechanism. According to the rice screening device, impurities in rice are effectively removed, the purity of the rice is improved, the quality of the rice is guaranteed, rapid collection and arrangement of dust and crushed stone are achieved, the rice screening efficiency is favorably improved, and thelabor intensity of rice processing personnel is relieved.

Description

technical field [0001] The invention relates to the technical field of grain processing, in particular to a paddy screening device for rice processing that takes into account the functions of both impurity removal and dust reduction. Background technique [0002] Rice is the finished product of rice after cleaning, husking, rice milling, finishing and other processes. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients needed by the human body. It is also the most important food in China. The main food of the people of the region. [0003] The screening of rice is an indispensable process in the rice processing procedure. Rice processing refers to the process of removing the chaff (chaff) and cortex (bran layer) of the rice. The rice is mixed with sand, gravel, fine dust and straw, etc. A variety of impurities, which cannot be removed during processing, not only affect safe production, reduce the quality of rice, but are also harmful to huma...
