ABSTRACT:
A vessel (10) is formed with a convexity of the shape of a dish (24). An immersion tube (40) protrudes into the vessel (10) and terminates inside the dish (24), being adapted for connection to a source of gas which will flow through the immersion tube in the direction of the dish by which it will be deflected so as to fluidize pulverous or granular material (30) contained in the vessel (10). A filter casing (50) is placed on top of the vessel (10) and it contains a filter (56) to hold back particles of material being treated which left the vessel. A rotating vane (60) is associated with the filter (56) and driven by a turbine (70) arranged in the immersion tube (40) so that the rotating vane will sweep across the filter (56). A slot nozzle (74) is formed at the rotating vane (60) and sucks off material from the filter (56) so as to keep it clean. The particles of material sucked off pass through a hollow shaft (62) into the immersion tube (40) and then back once more into the vessel (10).
