ABSTRACT
The various types of milling systems are aimed toward the production of refined products such as decorticated kernels, grits, semolina, and flours which are further processed into an array of prepared foods. These industries break away the anatomical parts of kernels with the purpose of obtaining the starchy endosperm as whole, grits, or flour. The industry also produces coproducts such as glumes, brans, germ, and lowgrade products. In general terms, the dry-milling industry is divided into four major segments: (1) traditional milling systems that yield semirefined products; (2) decortication and polishing for the production of white rice, pearled barley and oats, and decorticated sorghum or millets; (3) roller milling for the production of semolina and an array of wheat and small-grain flours; and (4) degerming-tempering systems for the production of an assortment of maize grits.
