Yamamoto, S.
A vertical frictionally abrasive roll rice polishing machine in which a vertical rotary shaft extended in the vertically axial direction of a framework assembly. A vertical frictionally abrasive roll was mounted at the upper end of the shift. A polishing cylinder surrounds the abrasive roll in coaxial and peripherally spaced relationship to the roll to define an annular polishing chamber there between. The polishing cylinder rotates and moves depending upon load applied thereto. The abrasive roll rotates but does not move vertically, a material supply passage was formed above the polishing chamber and a polished rice discharge passage was formed below the polishing chamber
