Rice screening method

Abstract

The invention discloses a rice screening method. According to the method, thirteen processes, namely blowing, screening and washing, blasting and drying, stone removal, magnetic separation, decldding, husked rice separation, thickness classification, rice milling, rice classification, colour selection, grade separation and finished product package, are adopted for finishing ice processing. According to the rice screening method, all process of a traditional process are optimized, all the steps are simplified, and the quality is ensured; especially a screening and washing process is added, so that dust and other water-soluble impurities can be removed by virtue of screening and washing, so that the rice is relatively clean, the prepared rice and rice chaff are relatively high in cleanliness and the rice product is high in quality and clean; a traditional polishing process is omitted, and a membrane which is rich in microelements at the outer surface of rice is reserved, so that losses of rice nutritional ingredients are prevented and the rice is relatively nutritional; the rice screening method is clear and reasonable in step, high in whole rice rate and high in production efficiency, and the prepared rice is high in nutritional ingredients, good in taste, high in quality and clean.

Description

technical field [0001] The invention relates to a screening method, in particular to a screening method for rice. Background technique [0002] Rice is an indispensable food for people's three meals a day. Rice contains about 75% carbohydrates, 7%-8% protein, 1.3%-1.8% fat, and is rich in B vitamins. The carbohydrates in rice are mainly starch, and the protein contained is mainly rice glutenin, followed by rice gelatin and globulin. High, digestibility 66.8%-83.1%, is also a kind of higher in cereal protein. The traditional rice processing method is a finished product after cleaning, hulling, rice milling, finishing and other processes. The design of the rice processing process is unreasonable, the steps are cumbersome, the efficiency is low, the quality of the rice is low, and it is easy to lose the rice in the rice. important nutrients. In view of the above-mentioned defects, it is necessary to design a screening method for rice to improve the technology. Contents of ...
