This evaporator consists of a cylindrical tube provided with a steam heating jacket and with a three-blade inner rotor that produces a very thin film of liquid on the walls. The automated version mod. Equipped with PID controller that enables to control the flow rate of steam to the evaporator and the vacuum degree of the plant, automatically. This type of evaporator is widely used in the industries for concentrating thermosensitive, viscous products, or dirtying products such as solutions containing sugar, enzymes, vitamins, proteins, fruit juices, fermentation broths, etc. The solution having to be concentrated is transferred from the storage tank to the evaporator by a metering pump; the vaporized solvent is condensed in a shell-and-tube condenser and then it is collected into a tank.
