Types of heat exchangers

In a vacuum evaporator, the heat necessary for the evaporation of the solution to be treated (latent heat of evaporation) is transferred through a specific heat exchanger. There are various types of exchangers:

• Submerged coil exchanger
• Shell and tube exchanger
• Plate exchanger
• Jacketed exchanger

Depending on the type of liquid to be treated (fouling, possible salt precipitations, etc.) and the goal to be achieved (liquid, solid, or semi-solid concentrate), certain types of exchangers are more suitable than others.
