A multiple effect evaporator (MEE) isa device that uses steam to evaporate water in a series of stages, or "effects", to concentrate dairy products and other liquid foods:
How it works
|
---|
Stages |
Each stage operates at a lower pressure and temperature than the last. |
Heating |
Steam in tubes heats the feed water at each stage. |
Evaporation |
Some water evaporates, and the resulting steam flows into the next stage. |
Condensation |
The vapor from the previous stage is condensed and used as the heating source for the next stage. |
In the dairy industry, MEE's are used to concentrate dairy products, which helps preserve flavors and reduce transportation costs.They can also be used to collect water from wastewater for reuse in industrial processes.
