Rice whitening method

Abstract

The invention discloses a rice whitening method. The rice whitening method comprises the following steps of (1) atomization treatment, namely soaking brown rice with a compound enzyme solution of cellulase, maltase and protease in a spraying manner; (2) rice milling, namely feeding the soaked brown rice in the step (1) into a rice milling device for rice milling; (3) discharging, namely conveyingmilled semi-polished rice from a rice milling box into a material distribution box; (4) primary screening, namely screening out large-grain rice and small-grain rice through a first filter screen; and(5) secondary screening, namely screening out the small-grain rice and impurity grains through a second filter screen. The invention relates to the technical field of rice processing. The method reduces the broken rice rate in the rice milling process, improves the rice milling quality and improves the rice processing efficiency.

Description

Technical field: [0001] The invention relates to the technical field of rice processing, in particular to a rice whitening method. Background technique: [0002] Rice is the staple food of southerners. In order to obtain high-quality rice, it needs to go through multiple steps of processing to obtain high-quality rice. Rice processing must first screen the rice, select good rice, and then perform preliminary cleaning, and remove the stones in the rice to avoid mixing stones in the rice. After husking, the husk of the rice is removed, and the husk is put into the rice husk and separated from the rice. The rice separated from the husk needs to be magnetically separated to remove metal debris and other impurities in the rice. Rough milling and finishing milling are performed on the rice from which impurities etc. have been discharged. Finally the rice is polished and finally packed. [0003] At present, the traditional rice milling method has a large mechanical pressure when...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional rice milling method has a large mechanical pressure when removing the cortex, which leads to high processing brittleness, and easily causes rice grains to break and crack, which not only affects the rice processing quality, but also has problems such as high energy consumption; After the completion, the rice grains of different sizes and the impurity particles mixed in the rice cannot be separated in time, which will increase the follow-up screening work
