Background

The rice bran is mixed in the rice in the processing process of the rice, the taste of the rice is influenced if the rice bran is not screened and separated, and meanwhile, research results and data at home and abroad show that the rice bran is rich in various nutrients and physiologically active substances. Edible rice bran is published in developed countries such as the United states at present, similar products are invented in China, namely, the modern food processing precise grinding technology is applied to precisely grind and separate non-beneficial substances (rice hulls, fruit peels, seed coats, dust, microorganisms and the like) and beneficial food nutrient substances (outer endosperm of embryos, aleurone layers and the like) in rice bran in a clean production workshop, the separation technology can be used for classifying the rice bran into feed-grade rice bran and food-grade rice bran, wherein the food-grade rice bran accounts for about 80% of the total weight of the rice bran and accounts for more than 90% of the nutrition. Food grade rice bran, although only 6% by weight of the rice and about 60% by weight of the rice nutrients, is a ground product in the rice whitening process, it is also called "rice bran" or "rice meal".

Consequently, it is very necessary to sieve out rice and rice bran, but directly carry out the chaff to the rice among the prior art, because the rice bran is more tight with the rice laminating, the screening process is slower, inefficiency, and most devices only adopt single vibrations screening simultaneously, and screening efficiency is low, and the screening result is unsatisfactory simultaneously
