<p>Method for evacuating a storage space for bulk goods, preferably granular material, e.g. cereal grain, by means of an evacuating conveyor constituting the floor of the space. The evacuation conveyor (15) is provided with perforations arranged in bands as passages for air streams. The air streams, which are directed along the floor (16), blow the bulk material (22) towards an outlet (21) or at least one outlet chute. At least portions of the perforation bands closest to the side walls (12) of the storage space, and some of the bands along essentially their entire and/or part of their length, emit an air stream, which in quantity and/or pressure differs from the air stream emitted in the remaining perforation bands.</p> |
