A fluidized bed granule coating assembly discharges effluent air containing unused high-value particles of an active ingredient, which is trapped in a collar-shaped filter (28). The filter dimensions are especially smaller in the longitudinal axis than in the transverse direction. The filter surface is consists of numerous small pockets (40) in a radial array. A fluidized bed granule coating assembly discharges effluent air containing unused high-value particles of an active ingredient, which is trapped in a collar-shaped filter (28). The filter dimensions are especially smaller in the longitudinal axis than in the transverse direction. The filter surface is consists of numerous small pockets (40) in a radial array. The pocket (40) outer surface is the dust-collecting face and the inner face (44) is the clean side. The pockets are separated by narrow gaps and linked by a common frame (48). The individual pockets have convex outer surfaces. The filter pocket (40) longitudinal axis is transverse to the filter longitudinal axis, especially approximately radial. Process air emerges from each pocket through the end-face. The filter is a woven textile, a metal gauze or a compound material. An Independent claim is also included for an associated pellet coating assembly.
