ABSTRACT:
The container of the fluidized-bed apparatus has two wall parts detachably connected to one another and contains a pivotable perforated bottom arranged approximately at the height of the abutment point of the two wall parts. Each of the two wall parts is provided, at the abutment point, with an annular groove essentially arc-shaped in cross-section. The two grooves together form a channel open toward the container interior and contain a hollow seal which is circular in cross-section in the relaxed state. Said seal can be deformed by a fluid under pressure which is passed into it, for example compressed air, in such a way that, at a first fluid pressure value, it connects the two wall parts tightly to one another and at the same time tightly to the perforated bottom and that, at a second, lower fluid pressure value, it still connects the two wall parts tightly to one another but is separated from the perforated bottom by annular gap, so that said perforated bottom can be swivelled.
