Abstract

An apparatus for the multi-stage refining of organic bulk materials according to the fluidized bed principle comprising a plurality of horizontally aligned cells (23) including an upper drying chamber (1), a middle degasification chamber (2) and a lower refining chamber (3) separated from each other by an individual gas permeable floor (19) or a gas impermeable floor (20). Adjacent cells are connected to each other by common discharge/charge chutes having vertical separation walls extending therein.
