Abstract
On the bottom surface of a store or silo for granular material is placed a system of air channels, which are at one end connected both with an outlet sluice for the grain material and with a blower housing, which is also connected with the free atmosphere. The blower housing is switchable between blowing drying air into the grain through the channels and through wall openings therein and sucking out air from the channels for outlet conveying the grain inwardly through the wall openings and further through the channels to the outlet sluice. By this suction emptying arrangement dust problems in the store are eliminated, and the necessary motor effect is surprisingly low.
