Apparatus for continuous treatment and transportation of a material (7), consisting of piece goods or granules of solid material, in an at least partly fluidized bed, which apparatus comprises a perforated trough bottom (5) for the material and means (3) for creating an upwardly directed air or gas flow through said trough bottom (5) and said material (7). The trough bottom (5) is disposed to move, from a starting position, in the conveying direction of the material (7) and opposite to the conveying direction of the material, the trough bottom in motion opposite to the conveying direction being disposed, relative to the material (7), to exhibit greater acceleration (a2) than a maximum acceleration (a1) relative to the surroundings in motion in the conveying direction. |
