An apparatus for fluidizing a bed (2) of a cohesive powder, situated in a container (1), comprises means (4, 5) for making a gas flow through the powder bed, means (13, 14) for stirring the powder bed, and means (3, 6) for vibrating the powder bed. Furthermore, in a method for fluidizing a bed of a cohesive powder, situated in a container, a gas flow is led through the powder bed, the powder bed is stirred, and the powder bed is vibrated. Herein the cohesive powder fluidizes well, without the powder grains coagulating or cracks or channels occurring in the powder bed. |
