Method for processing and purifying rice

Abstract

The invention provides a method for processing and purifying rice. The processing technology of the method is completed by thirteen technological processes as follows: unhulled rice screening, drying, stone removing, magnetic separating, rice hulling, husked rice separating, thickness grading, rice milling, white rice grading, color sorting, polishing, white rice grading and finished product packaging. According to the method for processing and purifying rice, impurities are removed through screening; after drying, the finished product rate can be increased in subsequent processing; the quality of rice can be improved through grading for multiple times; the processing course is pollution-free; and a low-temperature rice-rubbing and rice-milling mode is adopted, so that the broken rice rate is reduced, and the economic benefit is increased.

Description

technical field [0001] The invention relates to a rice processing technology, in particular to a method for removing impurities in rice processing. Background technique [0002] At present, in the rice processing technology, the raw grain is basically harvested by machine, and farmers basically do not over-process the grain, resulting in mixed raw grain, more impurities, and uneven moisture content, which brings great difficulties to rice processing. , after husking and rice milling, the temperature of the rice is higher. If it is directly sent to the polishing machine for polishing, it will cause the appearance to be rough and the rate of crushing will be high. In addition, the concept of consumers continues to increase the emphasis on the smoothness and taste of rice. Now the rice processed by a single variety cannot meet the needs of consumers. Contents of the invention [0003] The invention provides a rice processing impurity removal method capable of reducing the br...

[0002] At present, in the rice processing technology, the raw grain is basically harvested by machine, and farmers basically do not over-process the grain, resulting in mixed raw grain, more impurities, and uneven moisture content, which brings great difficulties to rice processing. , after husking and rice milling, the temperature of the rice is higher. If it is directly sent to the polishing machine for polishing, it will cause the appearance to be rough and the rate of crushing will be high. In addition, the concept of consumers is constantly increasing and they pay more attention to the cleanness and taste of rice. Now the rice processed by a single variety cannot meet the needs of consumers.
