Abstract

In order to create a sifting device with integrated static sifter member and dynamic sifter member having at least one rotatably disposed rod basket such that the two sifter members are optimally coordinated so as to operate efficiently, particularly with moist sifting material to be dried, it is proposed in accordance with the invention to have a bypass line leave from the intermediate area between the static member and the dynamic member of the sifting device for drawing off a partial flow of the sifting air flow/sifting gas flow and to supply only the remaining outgoing sifting air of the static sifter member (static cascade sifter or V-sifter) to the dynamic sifter member with the at least one rotatably disposed rod basket.
