The flour milling process begins with cleaning the grain and tempering it by adding water. The tempered grain is ground in a series of rollermills to remove the bran and to cut the endosperm. Between each rollermill cycle, the ground grain is sifted and separated into various sizes. Middle-size material is sent to a purifier, or shaking sifter, and on to another set of rollermills for further reduction and sifting into a variety of flours and flour blends. These are then stored in large bins.
