Claims19
A rotary dryer for drying herbaceous material, comprising:
- a dryer receptacle having an inner space for receiving herbaceous material;
- a driving device for rotating the dryer receptacle about a rotation axis of the dryer receptacle;
- and
- a channel-shaped collector being at least partially open in its upper portion and provided in the inner space of the dryer receptacle for collecting and retaining dried herbaceous material,
- wherein the channel-shaped collector is stationary during rotation of the dryer receptacle;
- and
- wherein the channel-shaped collector is asymmetrical with respect to a plane defined by the rotation axis of the dryer receptacle and a vertical direction extending through a center of the channel-shaped collector.
