During the plate evaporation process, liquid is pumped between thin plates with the heating medium on the mating surfaces. The product is then evaporated with the vapour generated forming a high velocity core. This expansion in volume causes a high-velocity, thin film on the heat exchange surface providing efficient heat transfer.
Plate evaporators should be considered for applications that have:
* Capacities up to 27,000 kg/h water removal
* A need for future expansion
* Limited head space
* A particle size smaller than 600 Micron
APV Product Range:
* Rising/falling film plate evaporators
The original plate type evaporator.
* Falling film plate evaporator
Combining all the advantages of the original Rising/Falling Film Plate Evaporator with the added benefits of even shorter product residence time and larger capacities.
* Paravap
The APV Paravap is specially designed to process high solids concentrates or those having non-Newtonian viscosity characteristics.
* Paraflash
For products which tend to crystallize during concentration or those that contain a high percentage of suspended solids.
