which can no longer or only with difficulty be conveyed being loosened again this desired effect is obtained in that the lifting unit in one embodiment lowers itself faster than the flexible receptacle with the granulate 10 present therein can fall back into the bottommost position under its own inertia another embodiment describes the change of position of the plate 21 which proceeds simultaneously with the change of position of the base 17 of the flexible receptacle 4 since these are in constant contact as a result of either the bottom or top dead center having abruptly been reached the granulate 10 present in the receptacle 4 is likewise abruptly stopped and thus the material structure or the bridging of the granulate 10 is altered as a result of the in both cases sudden mass stoppage of the receptacle 4 and the granulate 10 present therein the material structure of the granulate 10 or of the bulk material is altered such that the granulate is set into a free flowing state or this state is maintained after this the granulate 10 is conveyed out of the receptacle 4 in an upwardly directed material flow direction 25 by means of the suction lance 14 since the primarily vertical movement of the plate 21 transmits a primarily vertical movement to the lance 14 the guide 15 for the lance 14 is provided on the closed container lid 7 this guide 15 enables a motional play within a defined range and prevents.
