Abstract:
Apparatus for dispensing measured doses of granular and powdery bulk materials, comprising a balance for weighing the doses to be dispensed; a reservoir container for the bulk material with a bottom opening; a cover to close the bottom opening; a conveying and delivering device with a vertically displaceable conveyor body rotating about an essentially vertical axis; as well as an outlet passage for the bulk material to be dispensed; wherein the conveying and delivering device is incorporated in the cover; the conveyor body has a ring-shaped bottom with a tapered radial profile; the radial profile reaches into a ring-shaped conveyor channel recessed in the cover, the channel having a channel profile conforming to the tapered radial profile of the ring-shaped bottom of the conveyor body; and the outlet passage is arranged eccentrically of the vertical axis in a ring-shaped path swept by the conveyor body, thereby effecting a directionally guided and locally concentrated discharge stream of bulk material.
