How an Evaporator Works?

The working principle of the evaporator is to use the method of evaporation to vaporize and remove part of the solvent after heating the solution, thereby increasing the concentration of the solution, that is, the process of concentration of the solution. The equipment that performs the evaporation operation is called an evaporator. The basic parts of an evaporator usually consists of a heat exchanger, a vacuum pump, a vapor separator and a condenser.

What is difference between evaporator and condenser?


Evaporator absorbs heat; condenser discharges heat


The evaporator is mainly composed of a heating chamber and an evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation, so that the liquid is boiled and vaporized; the evaporation chamber is the part that separates the gas and the liquid.

The condenser is a component of the refrigeration system; it is also a component of the entire evaporator system.


The evaporator uses the principle of heating to heat the solution containing different substances to boiling, so that part of the solvent is vaporized and removed.

The condenser is mainly used to discharge heat, it can convert gas or vapor into liquid. During the evaporation process, the device that converts the vapor into a liquid state is called a condenser.
