Description
This unit consists of a falling-film evaporator equipped with a shell-and-tube condenser. The evaporator is fed by a metering pump and it operates under vacuum thanks to a liquid-ring vacuum pump. The concentrated product and the evaporated solvent are
collected into two glass tanks. The automated version includes a PID controller that enables to control automatically the flow rate of steam sent to the evaporator and the vacuum degree of the plant.
TRAINING PROGRAM
This unit enables to deepen the following issues:
• Mass balances
• Energy balances
• Determination of heat transfer coefficient
• Optimization of evaporation process
• Automatic flow and vacuum control by PID controller
• Plant supervision by P.C.
TECHNICAL SPECIFICATIONS:
• Framework of AISI 304 stainless steel with castors
• Metering pump of AISI 316 stainless steel, flow rate: 0-24 l/h
