Patent ID: 7578073

Claim:
Appliance for the removal of fluids and/or solids from a mixture of particulate materials with a container that constitutes a ring-shaped processing space with a cylindrical outer contour with devices for the charging and discharging of the particulate material into and out of the processing space and with a fan device for supplying a fluidization agent from underneath into the processing space as well as devices for the processing of the fluidization agent in the flow direction in front of the fan device, whereby in the processing space, cells are formed extending in the vertical direction through vertically extending walls where one cell constitutes a discharge cell through which there is no or a diminished fluidization agent flow from underneath where at the lower end of the discharge cell the discharge device is arranged and where another cell is provided with a charge device and forms a charge cell and where the cells are open at their upper ends, characterized in that, above the walls ( 8 ), there are arranged twist scoops ( 9 ), which are inclined or curved in the flow direction from charge cell ( 15 ) to discharge cell ( 17 ) and where the outside diameter of the twist scoops ( 9 ) is not greater than the outside diameter of walls ( 8 ) and where twist scoops ( 9 ) are surrounded by an outer jacket ( 3 ), which cell does not radially protrude outside over the outer jacket ( 3 ) that surrounds walls ( 8 ).
