Description

Technical Field

[0001] The utility model belongs to the technical field of rice bran removers, and in particular relates to a rice bran remover for processing. Background Art

[0002] Rice grains are composed of husk, cortex, embryo and endosperm. Rice processing refers to the process of removing the husk and bran layer of rice to finally make rice of better edible quality. The bran remover is mainly used to remove the bran layer and impurities in the rice. It separates the bran layer and impurities in the rice by setting the speed and wind pressure.

At the same time, the buckle assembly 10 is provided to facilitate the opening and closing of the flip plate 11.

[0032] Working principle: When in use, pour the rice into the feed box 1, and then it falls from the feed box 1 to one side of the sieve plate 506.

Finally, the separated rice will fall into the discharge funnel 7, so as to achieve the effect of clean bran removal.
