Dry milling and fractionation of grain Wikipedia

Dry milling of grain is mainly utilized to manufacture feedstock into consumer and industrial based products. This process is widely associated with the development of new biobased associated byproducts. The milling process separates the grain into four distinct physical components: the germ, flour, fine grits, and coarse grits.The separated materials are then reduced into food products
