The invention relates to the technical field of rice processing, and discloses a refining method for processing of rice. The refining method comprises the following steps of removing impurities from unhulled rice, screening the unhulled rice without impurities, removing husks of the screened unhulled rice, separating husked rice, performing careful selection, performing rice milling and polishing,performing color sorting and classifying, performing sterilization and performing packing. The weight of the unhulled rice is weighed, early stage experiment can be performed, and the results show that the weight of the unhulled rice is the same as that of water. An appropriate amount of water is added to an atomization plant, and is uniformly sprayed for wetting the unhulled rice, so that the brown rice moisture in the unhulled rice is maintained to 13.5%15.0%. The brown rice is atomized, sprayed with water and moisturized for some time, so that the friction coefficient of the surface of thebrown rice is increased, grinding, cutting, applying and separating of the cortex of the brown rice are facilitated, the milling pressure can be reduced, the brown rice in the rice milling process can be reduced, and the milled rice rate is increased. The refining method for processing of rice can solve the problem that the moisture of the brown rice in the unhulled rice is low to cause more broken rice during processing.
