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.
L'invention concerne un procédé permettant de vider un silo destiné à des produits en vrac, de préférence, granuleux comme des grains céréaliers, à l'aide d'un transporteur d'évacuation constituant le fond du silo. Le transporteur d'évacuation (15) est doté de perforations disposées en bandes qui permettent le passage de flux d'air. Les flux d'air dirigés le long du fond (16), soufflent la matière en vrac (22) vers une sortie (21) ou au moins vers un tuyau d'évacuation. Au moins les parties des bandes de perforations les plus proches des parois latérales (12) du silo, et certaines des bandes le long sensiblement de tout ou partie de leur longueur, cèdent un flux d'air dont la quantité et/ou la pression diffèrent de ceux des flux d'air cédés par les autres bandes de perforations.
