Rice primary cleaning method

Abstract

The invention belongs to the technical field of rice production equipment and particularly relates to a rice primary cleaning method. The rice primary cleaning method comprises the following steps ofextracting a screening module from an organic rice fine processing and screening device; preparing a plurality of two types of ring-shaped magnets with different outer diameters, adhering gauze onto the inner side of every ring-shaped magnet with a gap formed between the gauze and the ring-shaped magnet, mounting the two types of ring-shaped magnets with different outer diameters onto the inner walls of the outer barrel and the inner barrel of the screening module of the organic rice fine processing and screening device, and resetting the screening module; spraying clean water onto rice to bescreened, blow-drying the water-sprayed rice with an air cooler, and feeding the dried rice into the screening module of the organic rice fine processing and screening device for screening; starting the motor, the air pump and the dust cleaner of the organic rice fine processing and screening device, wherein the motor drives the screening module the screen the rice and the dust cleaning to clean dust in air. The rice primary cleaning method can improve the cleaning quality and save the workload of secondary cleaning.

Description

Technical field [0001] The invention belongs to the technical field of rice production equipment, and specifically is a method for preliminary cleaning of rice. Background technique [0002] Paddy is a finished product made from rice cleaning, hulling, rice milling, and finishing. The cleaning process is to use appropriate equipment, process and operation methods to remove all kinds of impurities mixed into the rice to improve the quality of the finished rice products, and to use magnets to remove iron nails and iron filings in the rice. To ensure production safety; the rice hulling process is to use a rubber roller hulling machine or emery hulling machine to remove the hulls of rice and separate the hulls from the brown rice; the rice milling process is to use a rice mill to mill and rub the brown rice The cortex is separated from the endosperm, and then the rice is brushed, chaff, shredded, and dried, so that the required grade of rice can be obtained; modern new rice also use...

AI Technical Summary

Problems solved by technology

[0003] Some existing rice production equipment uses magnets to remove iron nails and iron filings in the rice when cleaning rice. The iron nails and iron filings adsorbed on the magnet fall off by impact, which reduces the cleaning efficiency of the magnet on the iron substances in the rice, and needs to be cleaned again, which increases the rice production process and increases the cost.
