Rice magnetic separation processing method

Abstract

The invention relates to a rice magnetic separation processing method which adopts the following rice impurity rapid cleaning device, and the rice impurity rapid cleaning device comprises a conveyingbelt, a conduction plate, a side protection plate, a flattening plate, a linkage plate, an adjusting bracket and a suction mechanism; the rapid cleaning method for the rice processing blending impurities by adopting the rapid cleaning device for the rice impurities comprises the following steps: S1, conveying rice; S2, adjusting the height of the spreading plate; S3, performing magnetic separationof rice; and S4, performing rice collection. The rice magnetic separation processing method can solve the problems in the existing rice magnetic separation process: during magnetic separation of therice, the stacking heights are different, and the problems that the cleaning effect of iron impurities in rice is poor, conveying of the rice is affected to a certain extent by magnets, the rice has the hidden danger of falling off from a conveying belt, magnetic separation of the rice is incomplete, and scrap iron adsorbed by the magnets falls off due to the fact that the rice moves during conveying of the rice are solved.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a rice magnetic separation processing method. Background technique [0002] Rice is the most important staple food in our country; rice needs to go through the following processing steps from raw rice to finished product: raw rice screening, raw rice stone removal, magnetic separation, hulling, paddy separation and other steps. [0003] Rice will be doped with a certain amount of iron impurities during the harvesting and storage process. Rice magnetic separation is to absorb and separate the iron impurities doped in rice through a magnet. The magnetic separation of existing rice is generally passed above the rice conveyor belt. The iron filings doped in the rice are removed by setting a magnet block. The existing problems in the rice magnetic separation process are as follows: [0004] 1. Due to the different stacking heights of rice magnetic separation, the removal effe...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the different stacking heights of rice magnetic separation, the removal effect of iron impurities in rice is poor, and the magnet block will have a certain impact on the transmission of rice, which makes the rice fall from the conveyor belt. Hidden danger;

[0005] 2. The magnetic separation of rice will have the situation that the magnetic separation is not complete, and the iron filings accumulated in the rice cannot be absorbed, and the moving rice will cause the iron filings absorbed by the magnet to fall
