Abstract
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.

An apparatus for treatment and transportation of a material (7), consisting of piece goods or granules of solid material, in an at least partly fluidized bed, the apparatus comprising:
- a perforated trough bottom (5) for the material (7);
- means for moving the trough bottom from a starting position, in a conveying direction of the material (7) and also opposite to the conveying direction of the material (7), the means for moving the trough bottom being arranged to accelerate the trough bottom (5) in the direction opposite to the conveying direction at a greater acceleration (a2) relative to the material (7) than a maximum acceleration (a1) in the conveying direction;
- and
- means (3) for creating an upwardly directed air or gas flow through said trough bottom (5) and said material (7).
A method for treating and transporting a material (7), consisting of piece goods or granules of solid material, in an at least partly fluidized bed, the method comprising the steps of:
- moving a perforated trough bottom (5) with material (7) thereon from a starting position, in a conveying direction of the material (7) and also opposite to the conveying direction of the material (7), said step of moving including accelerating the trough bottom (5) in the direction opposite to the conveying direction at a greater acceleration (a2) relative to the material (7) than a maximum acceleration (a1) in the conveying direction;
- and
- creating an upwardly directed air or gas flow through said trough bottom (5) and said material (7).
The method according to 16, further comprising moving an overflow edge (6) together with the trough bottom (5).
