摘要： The dryer comprises a dryer receptacle having an inner space for receiving herbaceous material and a driving device for rotating the dryer receptacle about a rotation axis of the dryer receptacle. Vanes for engaging herbaceous material received in the inner space of the dryer receptacle extend from an inner surface of the dryer receptacle into the inner space of the dryer receptacle. In a cross-section with a sectional plane perpendicular to the rotation axis, the vanes are inclined with respect to the radial direction. Vane heating elements are incorporated into the vanes.
