Hulling Mill

 

a machine for hulling (removing the shell from the kernel) rice and oats for the production of groats. The principal working member consists of two horizontal millstones; the lower turns on a vertical axis, and the upper is fixed. The working surfaces of the millstones are coated with an abrasive. Grains are loaded into the gap between the millstones, where they are compressed and subjected to friction, which frees the kernels from the shells. The intensity of hulling depends mainly on the clearance between the millstones, which is regulated by a special lifting device. Hulling mills with millstones 1.25 m in diameter can process from 0.33 to 0.5 kg of grain per sec, depending on the type of grain. (SeeGROATS PRODUCTION.)
