Roller Milling | Baking Processes | BAKERpedia

Roller milling is one of many methods used to produce flour. It is a process used to separate the anatomical parts of grain kernels —like the bran, aleurone layers, germ and endosperm—and grind them down into fine flour particles. The flour is then used in the production of bakery products, pasta, breakfast cereals, pet foods and snacks. 1.
