Abstract

A housing having a heatable housing jacket, which surrounds a treatment chamber and forms a rotationally symmetrical treatment surface extending in the axial direction, and a drivable rotor, arranged in the treatment chamber and extending coaxially, for producing a material film on the treatment surface. The rotor comprises a hollow shaft, arranged in a manner distributed over the circumference of which are spreading elements. The hollow shaft surrounds a condensation space, in which a condenser is arranged. At least some of the spreading elements are configured as transport elements, which impart a transporting component to the material in the direction from the material inlet to the material outlet. Some of the spreading elements are configured as transport elements and some as distributing elements, which project from the hollow shaft and which comprise teeth, the shearing edge of which encloses an angle of less than 45° relative to the axial direction.
