Description
Technical field
The present invention relates to food processing technology field more particularly to a kind of big rice processing methods of efficient impurity removal.
Background technique
Currently, with the development of science and technology, color and purity in order to guarantee rice, people during processing rice,
Rice is finished using multiple tracks polishing and multiple tracks color sorting process, using multiple tracks polishing and multiple tracks color sorting process, although energy
Produce surface is very clean, bright rice and the variegated bad grain of rices such as removal is yellow, black, brown, but many nutrition of rice at
Divide and be lost also with polishing process, carries out multiple color sorting removal of impurities after polishing again, broken rice rate is higher.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of big rice processing methods of efficient impurity removal, no
Only dust removal rate is high, the water content of strict control paddy, and can promote rice husk quick separating, and rice husk removal is strong, mentions
Broken rice rate is reduced while high shelling rate.
A kind of big rice processing method of efficient impurity removal proposed by the present invention, includes the following steps:
S1, gangue, water are mixed, concentrated nitric acid is added under stirring, fluidized state stirring is filtered, washing, solids
It is dry, sodium hydroxide solution stirring is added, filters, washs, it is dry, p-aminophenyl trimethoxy silane, dodecyl is added
Benzene sulfonic acid sodium salt, water are uniformly mixed, and regulation system pH value is 4-5, are adjusted temperature stirring, are filtered, wash, dry, and calcining obtains the
One material；
