Abstract

The invention discloses a rice germ process which sequentially comprises the steps of: selecting high-quality rice; screening; removing stone; hulling rice; separating husked rice; storing brown rice; whitening; polishing; grading; color-sorting; packaging in vacuum; and obtaining a finished product. The whitening step is as follows: in a rice germ machine, the brown rice is fed to a sieve cage of the rice machine by using a feeding auger, hulls on surface layers of the brown rice grains, seed husks and perispern are removed by using mutual extrusion and friction actions among the brown rice grains, and aleurone layers and germ parts of the brown rice grains are maintained as far as possible, thus the taste of the rice germ is improved, and nutrients of the rice germ are remained furthest. The polishing step is as follows: water is added in the mutually extruded and rubbed rice germ in a sieve cage of a polishing machine, and the brightness of the rice grains is improved by using mutual friction action among the rice grains and wetting action of water to the rice grains so as to improve the commercial value of the rice germ. The rice produced by adopting the process has the characteristics of fully remained nutrients, freshness and better taste, and is rich in various trace elements without causing loss of more nutrients in a processing process. In order to activate the vitality in the germ, the germination process is implemented before eating, thus the purposes of saving energy, reducing consumption and ensuring the vitality of nutrients are achieved.
