Abstract
A pretreatment system for wheat to be floured comprises a plurality of friction type wheat polishing machines disposed in series relation to form a continuous wheat polishing process line. Each polishing machine includes a perforated tubular polishing member mounted on a frame and a frictionally polishing roll rotatably mounted on the frame. The polishing roll is disposed with the polishing member and cooperates therewith to define therebetween a polishing chamber. Upon the rotation of the polishing roll, it causes wheat grains supplied into the polishing chamber to be agitated and brought into frictional contact with each other to strip a pericarp from each wheat grain, to thereby polish the same. A moisture supplying device supplies moisture to the polishing chamber of at least one of the polishing machines, to add the moisture to the wheat grains flowing within the polishing chamber, to thereby increase a frictional contact force between the wheat grains. The friction between the wheat grains by the polishing roll causes each wheat grain to be moisturized and softened, to thereby facilitate the stripping of the pericarp from each wheat grain and the exposure of an endosperm part…
