Abstract

The invention is based on a star-shaped rotation dryer (1) for segmenting a fluidizing chamber 4) into process compartments (11), whereby the star-shaped rotation dryer (1) is pivot mounted and features dividing wall (9) or similar for the conveyance of solid particles along a conveyance path, whereby a flow-receiving base (10) is detachably mounted below the star-shaped rotation dryer (1); the invention further relates to a method of spray-coating solid particles for the purpose of agglomeration, coating, layering, spray granulation or pelletization, whereby the retention time spectrum of the solid particles inside the fluid-bed apparatus (2) has a margin of at least 1:3 (alternatively tRTD90≤3 tRTD10).
