- wherein the elevations rise at a distance from one another and traverse the drum in a path that varies circumferentially as the elevations travel in an axial direction;
- wherein agitators are disposed on an inner periphery of the drum jacket;
- and
- wherein the throughflow holes are disposed in the cylindrical regions.
