Embodiment 1

[0022] A rice finishing process, comprising the following steps: initial cleaning→microwave drying→cleaning→husking→separation of paddy and coarse grains→atomization and moistening→multi-stage rice milling→primary grading→polishing→sieving→color sorting→ultraviolet rays Irradiation→Measurement packaging and warehouse storage.

[0023] Early cleaning: The old or new sun-dried rice is first checked and accepted by the chemical industry to ensure that it meets the national standard GB1350, and then sent to the vibrating cleaning screen to remove large and medium impurities such as large gravel and sand.

[0024] Microwave drying: The rice after initial cleaning is sent to microwave drying equipment for drying treatment until its moisture content is 12%, and the working temperature of microwave drying equipment is 50°C. The rice is dried by microwave through the microwave drying equipment, which can increase the soluble amylopectin content of the rice, so that the rice processed b...

Embodiment 2

[0037] The processing method of this embodiment is consistent with the process of embodiment 1, and the working temperature of the microwave drying equipment is 45°C. After the rice is dried, the water content of the rice reaches 13%.

Embodiment 3

[0039] The processing method of this embodiment is consistent with the process of embodiment 1, and the working temperature of the microwave drying equipment is 47°C. After the rice is dried, the water content of the rice reaches 13%.

Abstract

The invention relates to a fine processing technology of rice. The fine processing technology comprises the steps of preliminary cleaning, microwave drying, clearing, unshelling, separation of rice from brown rice, atomization moistening brown rice, multilevel grinding rice, preliminary classifying, polishing, separating screening, color sorting, ultraviolet irradiating, calculating for packing and storing. According to the fine processing technology disclosed by the invention, microwave drying is additionally performed, so that the content of solubility amylopectin in rice is improved, and the taste of the rice is enhanced; the brown rice is atomized and moistened, and the water content of the brown rice is kept to be 14%-16%, a bran layer and an embryo expand after absorbing water and are softened, extrusion force required for grinding a surface layer can be reduced, crushing and cracks during the process of grinding rice is reduced, the rate of broken rice is reduced, and the rate of entire rice is increased; ultraviolet irradiation is additionally performed, so that residual bacteria or larval cells are destroyed, the expiration date of the rice is prolonged, and the rice is beneficial to human health.

Description

technical field [0001] The invention relates to the field of rice processing, in particular to a rice finishing process. Background technique [0002] The existing rice processing technology mainly includes: dry raw grain→primary clearing→stone removal→magnetic separation→hulling→separation of paddy and rough rice→rice milling→polishing→color sorting→grading→packaging, the above-mentioned multiple processes are combined and arranged, But in actual work, the whole rice rate and the rice yield rate of rice are low. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a rice finishing process with high rice yield, high rice yield, long shelf life and good taste. [0004] In order to achieve the above object, the technical solution of the present invention is: a rice finishing process, comprising the following steps: initial cleaning → microwave drying → cleaning → shelling → separation of grain and roughne...
