Claim:
1. A distribution unit for separating individual grains from a plurality of grains of a granular material comprising a housing having an inner circumferential surface, at least one inlet opening for conveyed granular material, a conveying device concentrically rotating in the housing for the conveyed granular material, and at least one outlet opening, which outlet opening connects approximately tangentially to the inner circumferential surface, the conveying device having one or more openings and/or steps at the outer periphery thereof, which, in a conveying region of the housing, form a pocket with the housing inner circumferential surface into which a plurality of the grains are urged and conveyed circularly by centrifugal forces, supported by the conveying device, and, in a separation region of the housing, only one individual grain of the plurality of grains remains in the opening or against the step of the conveying device due to a modified contour of the inner circumferential surface of the housing and under the influence of centrifugal forces, excess grains are advanced radially outward from the opening or from against the step of the conveying device and in turn are conveyed back to the conveying region of the housing for re-conveying.
