Rice milling device for rice processing and working method thereof

Abstract

The invention discloses a rice milling device for rice processing. The rice milling device comprises a feeding mechanism, a screening mechanism and a rice milling mechanism, wherein the feeding mechanism is connected with the screening mechanism through a first feeding channel; the rice milling mechanism is arranged below the screening mechanism; the feeding mechanism comprises a feeding groove; the lower portion of the feeding groove is fixedly connected with the feeding groove through a first feeding port; a stirring shaft is transversely fixed to the interior of the feeding groove; the left end of the stirring shaft penetrates through the left side wall of the feeding groove and then is fixedly connected with a rotating motor; and a plurality of stirring blades are fixed to the stirring shaft. When the discharge flow needs to be reduced, a driving motor drives a driving wheel to rotate in the opposite direction, so that a fixed block moves towards the inner side, and a gap between two discharging plates is reduced; and the feeding speed and flow are controlled by controlling the gap between the two discharging plates, so that quantitative feeding is achieved, the overflow of brown rice is prevented, the blockage of the brown rice is avoided, and the rice milling processing quality of the brown rice is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of rice processing, and relates to a rice milling device for rice processing and a working method thereof. Background technique [0002] Rice is the finished product of paddy after cleaning, husking, rice milling, finishing and other processes. The cleaning process is to use appropriate equipment, through appropriate technological processes and proper operation methods, to remove all kinds of impurities mixed in the rice, so as to improve the quality of the finished rice, and to use magnets to remove iron nails and iron filings in the rice. To ensure production safety. The hulling process is to use a rubber roller huller or an emery huller to remove the chaff of the rice and separate the chaff from the brown rice. The rice milling process is to use a rice mill to grind and rub the brown rice to separate the cortex and endosperm, and then to brush the rice, remove the bran, crush the rice, and dry the rice,...

AI Technical Summary

Problems solved by technology

[0003] Rice milling machine is a kind of grain processing machinery. It is used to remove the bran layer (cortex and germ) from brown rice and grind it into white rice. The brown rice is discharged from the rice outlet after the bran layer is removed in the whitening room, and the rice bran is discharged through the rice sieve. There are three main types of small rice mills in my country: separate rice mills, combined rice hullers and rice mills. Air-jet rice milling machine, separate rice milling machine is easy to operate and low in price, but the model is aging, and the quality of the milled rice is poor, and it is gradually facing elimination. The combined rice milling machine has good rice quality, but Its structure is complicated and the price is relatively expensive. The jet-type rice mill has good cost performance, and the processed finished rice is white and bright. In recent years, it has become the mainstream product in the market. The bran effect is poor, and a large amount of bran powder cannot be discharged out of the machine in time, so that the emery roller and rice sieve cannot effectively grind and screen the brown rice, so that better quality white rice cannot be obtained

[0004] Commonly used air-jet rice milling machines use air inlet holes to enter the air, the air intake resistance is large, the actual wind force is small, and the rice milling efficiency is low. In order to meet the requirements of rice processing quality, multiple rice milling machines need to be used, which consumes a lot of energy and takes up space for the equipment. Large, and because the wind is small, the heat in the rice milling room cannot be brought out in time, which will increase the temperature of the rice and increase the rate of broken rice
