Rice production method capable of reducing broken rice rate

Abstract

The invention discloses a rice production method capable of reducing the broken rice rate. The rice production method capable of reducing the broken rice rate is characterized by comprising the following steps: removing impurities in unhusked rice by using a roller precleaner and a vibrating screen to obtain pretreated unhulled rice; stirring potassium carbonate and water, adding the pretreated unhulled rice in a stirring state, and continuously stirring to obtain alkali-treated unhusked rice; drying the unhusked alkali-treated rice, adding a high-hardness adsorption compound, uniformly mixing, hulling, separating brown rice from the unhusked rice through a husked rice separator, adding automatic grading to separate rice grains and rice husks through the difference of specific gravity, granularity and the surface friction coefficient between the rice grains and the rice husks under the action of a working plate which tilts in two directions and reciprocates; peeling and whitening the rice grains, automatically sorting out and removing different-color grains in the rice grains, and then classifying the rice grains into rice, medium rice, small rice and broken rice according to the sizes of the rice grains by using an automatic sorting machine; and packaging.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production method for reducing the broken rice rate. Background technique [0002] Rice has become one of the staple foods in our country, and its nutritional value is also very rich, about 75% of carbohydrates, 7%-8% of protein, 1.3%-1.8% of fat, and 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. Therefore, edible rice has higher nutritional value. [0003] At present, the commonly used rice processing technology has many defects: when processing rice, there is no special cold rice warehouse, so that the storage time of rice is not long, and it is prone to deterioration; when polishing, it is often only polished once , due to many processes, the original polished rice cannot maintain ...

Problems solved by technology

[0003] At present, the commonly used rice processing technology has many defects: when processing rice, there is no special cold rice warehouse, so that the storage time of rice is not long, and it is prone to deterioration; when polishing, it is often only polished once , due to many processes, the original polished rice cannot maintain the original smoothness; in the grading process, only one grading is often performed, and the rice will be broken again in the last process in the follow-up process, resulting in The grading effect is not ideal; rice processing is carried out on the production line, if the previous process is too fast, it will also cause problems such as untimely packaging; the above series of problems will not only greatly reduce the product quality of rice, but also give Related production enterprises bring certain economic losses
