ABSTRACT:
Apparatus for dewatering and drying plastic granulate comprising a multistage dewatering rotor having conveyor and aerating blades and surrounded by a screening member located within a housing between a product inlet and a product outlet. In order to simplify the handling of a wide variety of plastic granulate with only a small amount of space being required, a collection container which is open at its top coaxially surrounds the first stage of the dewatering rotor and accumulates separated water in a reservoir region for discharge by a suction pump. The product inlet discharges into a feed vessel secured in the collection container. The first stage of the dewatering rotor is provided on its circumference with worm segments of increasing pitch in the direction of granulate conveyance.
