Device for peeling and/or grinding grain and seeds has helical bulges around rotor on working surface(s) of rotor or rotor segment(s) that protrude into processing chamber

摘要

The device has a processing chamber with an inlet and outlet, a shaft in the chamber driven by a drive, a processing rotor on the shaft and a filter drum enclosing the rotor at a distance. The working surface of the rotor, or the working surfaces of one or more of its segments (4a,4b) for a segmented rotor, has helical bulges (12) around the rotor that protrude into the processing chamber.
