Beschreibung
Zusammenfassung:	A device for the dehydration and drying of solids, especially granulated plastic materials, in the form of a mixture of granulate and water. Water passes through a curved sieve by an air current that flows in the direction in which the water passes through the sieve and also flows along the sieve. The mixture of granulate and water is delivered to the curved sieve through a delivery channel and whirled, by the energy of the air current, over the curved sieve and conveyed to an outlet duct, at the end of the curved sieve. On the curved sieve, an air jet that runs at an angle to the sieve, is directed for the admission of the air current. The mixture of granulate and water that is carried along by the air current, hits the curved sieve at an angle ranging, approximately between 25 DEG to 75 DEG in relation to the curved sieve. In the direction of flow, behind the air jet, is a cover which covers the curved sieve. The cover is adjacent to the rear wall of the air jet, and extends to the outlet passage. The cover is mounted to guide the granulate executing a shuttling rebound movement between the cover and the curved sieve.
