Abstract: A fluidized bed of solid particles, for instance of spray dried milk, is formed along a funnel wall by conveying the particles supplied to the upper funnel edge from above along the wall or by a body of gas which is introduced through a plurality of slits in the wall preferably in a direction substantially tangential to the circular cross section thereof to form a gas vortex. The gas vortex is preferably so distributed that its velocity is in direct proportion to the diameter of the conical wall.
