Description
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 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. 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 automated version is equipped with PID
controller that enables to control the flow rate of steam to the evaporator and the vacuum degree of the plant, automatically.
TRAINING PROGRAM
This unit enables to deepen the following issues:
• Mass balances
• Energy balances
• Determination of global heat transfer coefficient
• Optimization of evaporation process
• Automatic flow and vacuum control by PID controller
• Plant supervision by P.C.
