Embodiment Construction

[0016] Such as figure 1 As shown, a rice finishing process adopts the following process steps: first impurity removal - roughness breaking - paddy separation - fine milling - second impurity removal - post-treatment.

[0017] One-time impurity removal is the cleaning of organic impurities. The specific gravity de-stoner machine is used to remove the mud, stone sand and barnyard grains in the rice through multiple filtrations of the sieve.

[0018] The roughening adopts the wet roughening technology. Rice processing technology is the key technology to improve brown rice yield and reduce broken rice. In the rice finishing process, in addition to using a ceramic roller rice mill, the wetting and roughening technology is adopted, that is, according to the moisture content of the rough rice, add different degrees of water, and atomize it into a mist to make it Contact with the surface of the rough rice, when the surface of the rough rice is in instant contact with the rotating ce...

Abstract

The invention relates the rice fine finishing technique. The technique comprises the primary rouging which removes non-metallic impurity, separating grain, fine rolling, second rouging which removes metal impurities and final treatment comprising selecting color which removes other color grain with inductor, polishing which makes the surface of rice form film by heating rice with saturated vapor at a short time, classifying which is length classifier and thickness classifier with many sifters. The technique improves the rate of husked rice, reduces the broken rice and the waste of grain and increases the grain availability ratio.

Description

Technical field [0001] The invention relates to a rice finishing process. Background technique [0002] my country is a large agricultural country, and grain planting is still the main industry and the main source of economic income for the vast number of farmers in our country. However, due to historical reasons, my country's grain planting and grain processing technology still lags behind developed countries, with high labor intensity and high production costs. Reasons such as the low degree of mechanization have restricted the development of my country's grain commercialization and marketization. As far as rice processing is concerned, traditional rice mills are still used for workshop-style roughening and whitening. The lagging processing technology leads to a decrease in the whole grain rate and a large number of broken rice grains, which destroys the grain shape of the rice. The traditional milling technology processing actually causes the rice grains to collide, rub a...
