Problems solved by technology

[0003] However, even though the prior art has done a lot of research and discussion on rice, the technical effect it achieves is still unsatisfactory, and it is difficult to meet the needs of human life quality for nutritional elements to a large extent. Therefore, we urgently need to process rice. Provide a new way of thinking under the premise of reducing costs

Embodiment 1

[0025] Embodiment 1 adopts the paddy rice that Northeast produces as raw material to process refined rice according to the method of the present invention, and concrete processing method is as follows:

[0026] Put 1 ton of rice produced in Northeast China in a winnowing machine to screen the plump rice, so that the dry rice remaining in the rice is removed, and finally 0.86t of rice is obtained;

[0027] The obtained 0.86t plump rice is subjected to impurity removal treatment, and the remaining straw and other larger granular substances in the rice are excluded to obtain 0.79t rice;

[0028] The dust contained in the 0.79t of paddy after the cleaning process is blown by a wind pressure of 100MPa to remove the dust remaining on the surface of the paddy and obtain 0.786t of paddy;

[0029] Put 0.786t of dedusted rice in a magnetic separator for a magnetic separation to reduce the content of iron filings in the rice and obtain 0.785t;

[0030] Then remove the remaining stones i...

Embodiment 2

[0038] Embodiment 2 adopts northern Guizhou paddy as raw material, processes and produces polished rice, and its specific processing method is as follows:

[0039] Put 0.5t of rice in northern Guizhou into a winnowing machine to screen the plump rice, so that the dry rice remaining in the rice is removed, and finally 0.45t of rice is obtained;

[0040] The obtained 0.45t plump paddy is subjected to impurity-removing treatment, and the existence of residual straw and other larger granular substances in the paddy is excluded, and 0.43t paddy is obtained;

[0041] The dust contained in the 0.43t paddy after the cleaning process is turned over and blown with a wind pressure of 100MPa to remove the dust remaining on the surface of the paddy to obtain 0.421t paddy;

[0042] Put 0.421t of dedusted rice in a magnetic separator for a magnetic separation to reduce the content of iron filings in the rice and obtain 0.420t;

[0043] Then remove the remaining stones in the rice according ...

Abstract

The invention relates to the technical field of rice processing, particularly to a polished rice processing method with the rice embryo content more than 80%. The method comprises steps as follows: winnowing, impurity removal, dust removal, primary magnetic separation, primary stone removal, husking, rice bran separation, secondary stone removal, secondary magnetic separation, coarse grinding, fine grinding, classification, polishing, wind screening, color sorting and packaging. Proper embryo pulp or mixed pulp is sprayed on surfaces of rice grains repeatedly, so that nutrient elements in the rice are difficult to remove during processing, on the contrary, the content of the nutrient elements in the rice is increased, the nutrient structure and the taste of the rice are improved, all nutritive indexes meet requirements of the Food Hygiene Law, the rice embryo content of the processed rice is more than 80%, the polished rice degree is more than 95%, and the broken rice content does not exceed 5%.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a method for processing polished rice with a rice germ content of more than 80%. Background technique [0002] Rice is one of the staple food products in our country, which is peeled from the rice paddy; with the improvement of people's living standards, the quality requirements of rice are also getting higher and higher. For this reason, many researchers have studied rice processing technology and A lot of research and improvement have been done on rice processing equipment to enrich the nutrients in rice and the structure of rice; for example, the patent No. is CN92107126.4 "Processing Method of Clean Rice and Its Complete Equipment" and the patent No. is CN90102651. 4 The two patents of "Refined Pearlescent Rice Production Method and Equipment" both use special equipment and production technology to improve the quality and nutritional structure of rice, and change the ...
