Roller Milling

A C19th development (Budapest 1839. Britain 1880) in which the grain is gradually reduced to flour by being repeatedly passed between pairs of rollers. The rollers are set progressively closer together and sieving takes place between each pair, to separate flour from bran and germ. The rollers rotate with different surface speeds to facilitate the grinding process. Rollers which deal with whole grain & coarser particles are fluted to enable them to operate effectively. Some rollers may employ water cooling to limit the temperature rise of the product. See HOLDING ROLL.
