Problems solved by technology

[0002] At present, with the development of science and technology, in order to ensure the color and purity of rice, people use multi-channel polishing and multi-channel color sorting processes to finish the rice in the process of processing rice. , although it can produce rice with clean and bright surface and remove yellow, black, brown and other bad rice grains, many nutrients of rice are also lost during the polishing process. After polishing, multiple color selection and impurity removal are performed , higher broken rice rate

Abstract

The invention discloses a rice processing method for removing impurities efficiently. The method comprises the steps that coal gangue and water are mixed, concentrated nitric acid is added in a stirring state, stirring is carried out during boiling, filtration, washing and solid drying are carried out, a sodium hydroxide solution is added, stirring, filtration, washing and drying are carried out,P-aminophenyl trimethoxysilane, sodium dodecyl benzene sulfonate and water are added to be mixed evenly, the system pH value is adjusted to be 4-5, the temperature is adjusted, stirring, filtration, washing, drying and calcination are carried out, and a first material is obtained; sodium bicarbonate and water are stirred, impurity-removed unhulled rice is added in a stirring state, and stirring continues to be carried out to obtain a second material; the second material is dried and added into the first material to be mixed evenly, the mixture is fed into a rice huller for hulling, the distance of rubber rollers of the rice huller is 0.8-1.2mm, coarse rice is separated from unhulled rice through a rice-hull separation machine, and hulling, whitening and polishing are carried out.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a rice processing method for efficient impurity removal. Background technique [0002] At present, with the development of science and technology, in order to ensure the color and purity of rice, people use multi-channel polishing and multi-channel color sorting processes to finish the rice in the process of processing rice. , although it can produce rice with clean and bright surface and remove yellow, black, brown and other bad rice grains, many nutrients of rice are also lost during the polishing process. After polishing, multiple color selection and impurity removal are performed , The rate of broken rice is higher. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a rice processing method with high efficiency of impurity removal, which not only has high impurity removal efficiency, but a...
