Abstract
A device for the thermal treatment of material comprises a housing having a heatable housing jacket, which surrounds a treatment chamber and forms a rotationally symmetrical treatment surface extending in an axial direction, and a drivable rotor, which is arranged in the treatment chamber and extends coaxially. The rotor comprises a shaft, arranged in a manner distributed over the circumference of which are spreading elements. The device also comprises a condensation space, in which a condenser is formed and into which gaseous material components escaping from the material during the thermal treatment can pass, a condensate outlet for discharging the material components condensed in the condensation space, and a vacuum connection, which is fluidically connected to the condensation space. The vacuum connection is arranged in a region of the housing that lies downstream of the treatment surface, as viewed in the transport direction of the material.
