ABSTRACT:
A thin layer evaporator comprises a container forming a body, a container cover on the one side, a drive shaft projecting into the container from the opposite side, a rotor fixed to the drive shaft and which has one or more conically outwardly widening evaporator areas and whose evaporator chamber is connected to the body, as well as a heating chamber separated from the body. The starting product is fed to the inner periphery of the evaporator areas, spreads outwards therefrom in a thin film and the concentrate is removed on the outer periphery by means of a draw-off pipe. In order to be able to absorb dynamic forces in a vibration free manner, the drive shaft is partly constructed as a hollow shaft and is mounted on a fixed spindle projecting into the container and rotor.
