Abstract
A grain polishing machine of a vertical shaft and friction type in which a vertical polishing rotor and a bran removing polishing cylinder surrounding the former have each different diameters so as to have step parts dividing a polishing chamber defined between the polishing rotor and the polishing cylinder into a plurality of parts which are communicated with each other through connection passages that are defined between the step parts of the polishing rotor and the polishing cylinder thereby to prevent the weight of grain in the upper part of the polishing chamber from affecting the polishing pressure in the lower part thereof so that the polishing pressure in the polishing chamber is made to be uniform as a whole.
