Evaporation Technology
Often used in combination with the Falling Film Evaporator. Shell-and-tube heat exchanger or plate heat exchanger as calandria. With flash/vessel separator arranged above the calandria and circulation pump.
The Forced Circulation Evaporator is often used in combination with the Falling Film Evaporator as high concentrator or as crystallization evaporator for saline solutions.
Especially adequate for highly viscous liquids or with a high tendency to fouling as well as a high concentration step in multiple-effect evaporation plants. GEA offers different design options depending on product specifications and customer requirements.
The liquid is circulated through the calandria by means of a circulation pump, where it is superheated at an elevated pressure, higher than its normal boiling pressure. By entering the separator, the pressure in the liquid is rapidly reduced, resulting in some of the liquid being flashed or rapidly boiled off.
Since liquid circulation is maintained, the flow velocity in the tubes and the liquid temperature can be controlled to suit the product requirements independently of the pre-selected temperature difference.
Best suited for temperature-sensitive products and liquids with small amounts of solids and going up to high concentrations
Best, but not only, for extreme evaporation conditions or liquids containing only small amounts of undissolved solids with a low tendency to form incrustations
Concentrated food products need to be sterilized before they can be stored, packed or dried.
Test facilities available for laboratory and pilot plant testing for different kinds of evaporator systems.
