Vacuum evaporators are designed to increase the solids content (concentration) in the substrate.
Is the gradual removal (evaporation) of moisture due to the introduction of heat into the body of the evaporator itself. Live steam is usually used as a heat agent. To generate heat, it is possible to use natural gas, liquid or solid fuel.
To optimize heat consumption, evaporative plants are designed in such a way as to be able to use the secondary heat that is generated during operation (recuperative cycles).
The design of such an installation assumes the presence of three-, four-, five-case apparatuses, where "fresh steam" is introduced into one casing of the installation, while others operate under vacuum.
