摘要： For separating and drying pellets from a suspension, centrifugal dryers have proved successful wherein a rotor equipped with conveyor blades and disposed vertically in an outside housing for collecting the liquid is enclosed coaxially by a hollow body formed of screen elements. The suspension of pellets and liquid is supplied continuously to the lower area of the space between the hollow body and the rotor. The pellets are transported upward by the conveyor blades rotating with the rotor while being thrown back and forth and dried between the conveyor blades and the screens. At the upper end of the rotor the dried pellets are thrown off. The liquid separated from the pellets passes through the screen jacket and flows out of the discharge port of the outside housing. In a centrifugal dryer the hollow body enclosing the rotor (1, 28) equipped with conveyor blades (8, 13, 12, 27) consists of screen elements (15) only in the lower area or not at all, consisting rather of an unperforated jacket (21, 29) on whose inside wall the separated liquid flows downward in a spiral shape. An outside housing (17) is omitted in the area of the unperforated jacket.
