ABSTRACT:
Internally of an insert arranged within a container there is disposed a pre-evaporator, which at its lower end has an inlet for the starting material and at its upper end opens into a treatment compartment or chamber. The pre-evaporator is surrounded by a heating jacket whose outer surface serves as a heated treatment wall. For forming a thin layer there coact, with such treatment wall, up and down movable wiper elements. Arranged coaxially with respect to the insert or insert member, within the container, is a surface condenser. The starting material or product which is to be processed, is pre-evaporated within the pre-evaporator and subjected, along the treatment wall, to a final evaporation. The lighter volatile constituents condense at the surface condenser, and the condensate can be separately outfed from the concentrate which is formed during the final evaporation.
