Abstract
A re-threshing apparatus and method for a combine harvester includes a rotor having threshing elements mounted thereon extending substantially radially. The rotor is rotationally mounted within a housing at least partially surrounding the rotor. The housing includes an inlet and an outlet. The housing has a wall portion with rasp bars extending toward the rotor. The wall portion is substantially solid, i.e., material re-threshed by the rasp bars remains within the housing until it moves through the housing outlet. The rotor and the housing are configured for tailings to be flung tangentially into the housing against the rasp bars and re-threshed between the threshing elements and the rasp bars within the housing.
