Technical Field

The invention relates to the technical field of agricultural product processing, in particular to a rice processing method.

Background

With the gradual rise of the rice yield in China and the demand of consumers on refined rice, the rapid development of a plurality of rice processing enterprises is promoted. Refined rice is now required to have higher and higher quality requirements, such as uniform rice grain size, large grains, white surface, no pesticide residue, and the like.

The rice processing mainly comprises three procedures: cleaning, rice hulling and rice milling. However, the existing processing method has relatively few steps for processing the rice, and cannot ensure the early processing quality and the processing efficiency of the rice.

Disclosure of Invention

step 2, putting the plump rice into a cleaning cylinder for cleaning, when putting the rice into the cleaning cylinder, firstly pouring the rice into a reticular cleaning barrel, then extending a cleaning brush into the cleaning barrel to clean the surface of the rice, and taking the cleaning barrel out of the cleaning cylinder after the rice in the cleaning barrel is cleaned;

step 3, pouring the cleaned rice into a drying box for drying, and removing the moisture on the surface of the rice;

step 4, sterilizing the rice by using a magnetic sterilization method, and grading the rice according to the grain size by using a thickness grading machine, wherein the large grain size is A-grade rice, and the small grain size is B-grade rice;

step 5, shelling the A-grade paddy to obtain an A-grade paddy mixture, and shelling the B-grade paddy to obtain a B-grade paddy mixture;

step 6, separating the A-grade brown rice mixture and the B-grade brown rice mixture respectively, and separating the hulled brown rice from unhulled rice to obtain the A-grade brown rice and the B-grade brown rice respectively;

step 7, grinding the A-grade brown rice by using a rice mill to obtain A-grade rice, and grinding the B-grade brown rice by using the rice mill to obtain B-grade rice;

step 8, respectively pouring the grade A rice and the grade B rice into a storage box placed in cold water, so that the grade A rice and the grade B rice in the storage box are rapidly cooled;

step 8, polishing the grade A rice and the grade B rice respectively by a polishing machine;

step 9, mixing the grade A rice and the grade B rice to obtain a semi-finished product rice, and screening the semi-finished product rice by using a rice separation sieve to remove all broken rice;

step 10, screening the screened semi-finished rice again by using a color selector, removing the heterochromatic rice grains to obtain finished rice, checking the screened heterochromatic rice grains by using another color selector, separating normal rice grains from the heterochromatic rice grains, and mixing the checked normal rice grains into the finished rice;

and 11, finally, packaging the finished rice product.

In a preferred embodiment of the present invention, the grade a rice is rice with a grain size of more than 1.5mm, and the grade B rice is rice with a grain size of less than 1.5 mm.

Due to the adoption of the technical scheme, the invention has the beneficial effects that: the invention can grade the rice, improve the processing quality, facilitate the subsequent sale and improve the processing efficiency.

Detailed Description
