Device for dewatering and drying solids, especially plastics granulated under water, in form of a centrifuge dryer comprising a housing ( 1 ) having an inlet opening ( 2 ) for the solid material with adhering water and an outlet opening ( 3 ) for the dehydrated solid material, a screen cylinder ( 4 ) fixedly disposed inside the housing ( 1 ), a rotor ( 5 ) arranged inside the screen cylinder ( 4 ) and wings ( 6 ) attached to the rotor at a distance from one another, a water drain ( 7 ), and arrangements ( 8, 8 ') for the introduction and removal of an air stream passing vertically through the device. It is distinguished on the one hand in that the inlet opening ( 2 ) is arranged tangential to the screen cylinder ( 4, 10 ). On the other hand it is distinguished in that the fixed screen cylinder ( 4 ) is comprised of at least three screen cylinders ( 10, 11, 12 ) arranged vertically one over another, each of the screen cylinders ( 10, 11, 12 ) is being comprised of at least two segment shells ( 10, 10', 11, 11', 12, 12 ') where the lowermost screen cylinder ( 10 ) is comprised of a screen-like shell ( 10 ') and a solid segment shell ( 10 '').
