Liquids containing solid materials in soluble or suspended form are atomized in a chamber (1) while admitting a drying gas. Subsequently, partially dried particles settle on the bottom of the chamber or under this chamber on a perforated conveyor belt (8) where they are subject to a final drying in order to obtain a homogeneous porous layer while sucking drying gas through the layer. The generation of a whirling movement in the lower part of the chamber or in a zone (12) immediately over the part of the conveyor belt (8) where the particles settle ensures an even distribution of the particles while forming a layer (13) of a constant thickness on the conveyor belt (8). |
