The invention relates to an appliance (1) for the removal of fluids and/or solids from a mixture of particulate materials with a container (2) that constitutes a ring-shaped processing space (20) with a cylindrical outer contour with devices for the charging and discharging of the particulate material into and out of the processing space (20) and with a fan device (5) for supplying a fluidization agent from underneath into the processing space (20) as well as devices (6) for the processing of the fluidization agent in the flow direction in front of the fan device, whereby in the processing space (20) cells (15, 16, 17) are formed extending in the vertical direction, where one cell constitutes a discharge cell (17) through which there is no fluidization agent flow from underneath, where at the lower end of the discharge cell the discharge device is arranged, and where another cell (15) is provided with a charge device, and where the cells (15, 16, 17) are open at their upper ends in order to enable the transport of the material to the discharge cell (17), whereby above the processing space (20) twist scoops (9) adjoin, which are inclined or curved in the flow direction from the charge cell (15) to the discharge cell (17), the outside diameter of said twist scoops not being greater than the outside diameter of the processing space (20) and said twist scoops being surrounded by an outer jacket (3) that does not radially protrude over the outer jacket (3) of processing space (20).
