[0002] Millet (original name: millet, also known as sorghum, foxtail grass, yellow millet, millet, Poaceae, foxtail grass annual herb, thick fibrous roots, thick stalks, millet is the result of peeling millet, millet is a cereal plant, a kind of grass, millet has high nutritional value, rich in protein, fat and vitamins, it is not only for food, but also for medicine to clear heat, quench thirst, nourish yin, nourish the spleen and kidney and stomach, promote urination, treat watery diarrhea, etc., and can also be used to make wine. Its stems and leaves are also excellent feed for livestock. It contains 5-7% crude protein, which is 1.5-2 times more than the content of general forage, and it has less cellulose and a softer texture. It is liked by mules and horses; its bran is also a good feed for pigs and chickens.

[0003] Millet needs to be debranched during processing. Existing debranning equipment generally uses specific gravity difference to debran millet, resulting in a large amount of dust in the rice bran, which makes it inconvenient to recycle the rice bran.
