APV Plate Evaporators


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 vapor 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 Plate Evaporator Features:
  • Improved product quality. The short heat contact period resulting from single pass operation and low liquid holdup eliminates product deterioration even when highly heat sensitive liquids are involved. The resulting concentrate is of the highest quality possible.
  • Higher product concentration. The variety of plate evaporators available from APV allows custom concentrates to be produced. Ninety seven percent total solids or better are possible depending on feed material characteristics.
  • Low liquid holdup. Very little product is actually in the plate evaporator at any time. This permits rapid start-up and shutdown with minimal waste. Small quantities of product may be processed economically.
  • Easily cleaned. All stainless steel surfaces within the plate packs are fully accessible for easy cleaning. Normal CIP is done with low consumption of cleaning chemicals due to the low liquid holdup.
  • Flexible capacity. By simply adding or removing plate units, varying evaporation rates may be achieved. Large expansions are possible with additional frames and plate units.
  • Low installation costs. Due to the compact size and low weight, no cranes or special foundations are required for installation. Typically, an existing building on site is suitable and installation time is minimal.
