Abstract

The invention relates to a rice polishing machine including a housing with a shaft which is mounted essentially horizontally therein and which carries a drive coupling member on one end thereof and a polishing rotor with a polishing surface on the opposite end thereof, and also carries a conveyor screw connected coaxially and fixedly to the polishing rotor. The housing is provided with a rice feed orifice at the conveyor screw, and with a rice discharge orifice at the end remote from the conveyor screw. In addition, a screen housing is provided, surrounding the rotor at a short distance therefrom, and a funnel member is provided underneath the screen housing for collecting and discharging the polishing powder. The present invention contemplates an uncomplicated and easily understandable construction which can easily be dismantled and is easily maintained. The polishing rotor and the screen housing are arranged conically with their wider or thicker edges being adjacent to the conveyor screw, and are mounted overhanging on the side of the conveyor screw by means of the bearing tube. The bearing tube surrounds the shaft and is fastened so as to be axially displaceable within a housing cover closing of the housing beyond the rice feed orifice, the internal diameter of the housing in the region of the conveyor screw being greater than the maximum diameter of the rotor, so that the housing cover could be removed from the housing together with the bearing tube, the shaft, the rotor, the conveyor screw and the drive coupling member. The machine requires no fans and can, therefore, be operated with only a mechanical drive without the need for an electrical connection.
