Whitening apparatus for super-glossy white rice

摘要

Disclosed is the improvements in whitening apparatus for producing strongly glossy white rice without using any gloss additive. The improved apparatus wherein: friction between half-finished white rice grains which have been moistened while being supplied to a whitening chamber of the apparatus is caused by the rotation of a whitening roll axially disposed in a perforated bran-removing and whitening cylinder, said roll and said cylinder are defining therebetween said whitening chamber, whereby the surfaces of grains are fully cleaned of bran which is constantly discharged through the perforated wall of said cylinder, thereby enabling to expose hard portions of white rice grains devoid of bran. The ratio between the length and diameter of said cylinder experimentally substantiated for best results may be between 2:1 to 20:1.
