Evaporation Technology
Plate heat exchanger and separator of compact design, short connecting lines and low overall height. Employs special plates with alternate product and heating channels.
Well suited for its use with temperature-sensitive or viscous products as well as under extreme evaporation conditions.
A plate-and-frame configuration employs special plates with alternate product and heating channels. The plates are sealed by gaskets located within specially designed slots that do not require adhesives. These gaskets can be inserted and removed without special tools.
The concentrated liquid and vapors are separated in a downstream centrifugal separator.
With little space requirements thanks to its compact design, short connecting lines and overall low height (between 4 and 6 meters), the plate evaporator is especially appropriate for low to medium evaporation rates and the treatment of liquids containing only small amounts of undissolved solids and with low tendency to form incrustations.
GEA will find the appropriate design according to the product and plant requirements.
Product and heating media are transferred in counterflow through their relevant passages. Defined plate distances in conjunction with specially shaped plates generate strong turbulence resulting in an optimal heat transfer.
Intensive heat transfer causes the product to boil while the generated vapor drives the residual liquid, as a rising film, into the vapor duct of the plate package. Residual liquid and vapors are separated in the downstream centrifugal separator.
The wide inlet duct and the upward movement ensure optimal distribution over the total cross-section of the heat exchanger.
Best suited for temperature-sensitive products and liquids with small amounts of solids and going up to high concentrations
Test facilities available for laboratory and pilot plant testing for different kinds of evaporator systems.
Concentrated food products need to be sterilized before they can be stored, packed or dried.
