ABSTRACT:
In a thin film evaporator for the evaporation of solutions, colloids, suspensions, or the like, to concentrates, which has a heatable cylindrical evaporator casing coupled with a rotary drive, which evaporator casing has a feed inlet at one end, in the form of a feed distributor that runs on bearings and is coupled with a rotary drive, and at the other end has a concentrate discharge, the axis of the evaporator casing is arranged horizontally. The distal end of the feed distributor can reach the inside surface of the evaporator casing to within less than 2 cm. Wiper elements can work together with the effective surface of the evaporator casing. This thin film evaporator makes possible an optimal setting of the retention time of the process material to be treated in the evaporator casing and has the effect that the thickness of the layer of the process material changes very little over the entire axial length.
