ABSTRACT:
A central immersion pipe (40) projects from above into a receptacle (10) which is axially symmetrical in relation to a perpendicular receptacle axis (A) and has an annular lower portion (12) with downwardly decreasing diameter. The lower portion (12) leads into a basin (16) which is likewise axially symmetrical in relation to the receptacle axis (A). At the lower end of the immersion pipe (40) is a bulge (42) which, together with the basin (16), reroutes by 180.degree. a gas flow introduced from above through the immersion pipe (40) so that the gas, for example, warm dry air, flows upwards in a tubular flow formation around the immersion pipe (40) and fluidizes material (C) contained in the receptacle (10), said material being circulated with low consumption of energy.
