Rice grain production and processing technology

Abstract

The invention provides a rice grain production and processing technology, and relates to the technical field of rice processing. The rice grain production and processing technology comprises the following steps that after acceptance of unhusked rice, the unhusked rice is stacked in a warehouse, the unhusked rice is screened in sunny days and impurities such as weeds, rice stems and stones are removed, then the unhusked rice is placed in a magnetic separator for iron removal, then the unhusked rice is dried for 1-3d and then transferred to a drying room, and a hot-air blower is used for hot-airdrying of the unhusked rice; the unhusked rice is transported by a belt conveyor to a rice huller for husking; brown rice is transported to a rice mill for three times of rice milling treatment in sequence, the brown rice is atomized between the first and second times of rice milling treatment, and the brown rice is dried by 1-5 DEG C drying air between the second and third times of rice millingtreatment; and the rice cooled to the room temperature is polished and then placed in a color sorting machine for color sorting, and then rice finished products can be sterilized and packaged. Compared with a general rice grain production and processing technology, the broken rice rate is greatly reduced, the quality of rice grains is greatly improved, and the added value of the products is increased.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a process for producing and processing rice grains. Background technique [0002] Rice (Rice) is a finished product made of rice after cleaning, husking, rice milling, and finished product finishing. The germ and aleurone layer of rice contain nearly 64% of the nutrition of rice and more than 90% of the nutrients needed by the human body. It is the main food of the southern people. [0003] Traditional Chinese medicine believes that rice is sweet and flat, and has the effects of nourishing the middle and nourishing qi, strengthening the spleen and nourishing the stomach, benefiting the essence and strengthening the will, harmonizing the five internal organs, clearing the blood vessels, improving ears, improving eyesight, relieving restlessness, quenching thirst, and relieving diarrhea. It is known as "the first of the five grains" , is the main food crop in China, accoun...

AI Technical Summary

Problems solved by technology

[0006] In the actual production process, the rate of broken rice in rice obtained by rice processing technology accounts for 15-30%. Due to the following two reasons, the rate of broken rice will increase: the first is various treatments before rice processing, including rice The state of harvesting, during the process of threshing, tumbling, loading and unloading machine transportation, etc., the rice is crushed by mechanical impact; the second is the process performance of rice processing machinery and equipment and operation management level, etc.
