  • Flour Mill - an overview ScienceDirect Topics

    The first roller mills are employed in the break system. This is the part of the milling operation designed to remove the endosperm from the bran and germ. Rolls in this process have spiral grooves called “corrugations” cut parallel to the long axis of each roll (Fig. 2.7). Generally there are about five roller mills or five “breaks” in the system.
