Abstract
Apparatus and method for the independently regulated distribution of granulate to a plurality of points of consumption. A container (1), at least partially filled with granulate (10) to be distributed, includes a plurality of container apertures (4) each covered by a slide (5). A rotatable shaft (2) longitudinally disposed in front of apertures (4) is driven by a drive (3) at controllable rates. Granulate (10) adheres by friction to the surface of shaft (2) when rotated and is conveyed via the shaft to a plurality of troughs (6) where the granulate is collected. The granulate then flows through feed tubes (7) to air injectors (8) where it is entrained into an airstream and propelled to a plurality of points of consumption. The method according to the present invention includes the steps of: Storing granulate in a container having slide controlled apertures; rotating a shaft in the vicinity of these apertures; conveying granulate along the surface of the shaft; receiving the conveyed granulate into a plurality of troughs, each trough corresponding to an aperture; and conducting the granulate at each trough through an associated air injector to distribution pipes for conduction to a …
