  • Improved product quality
  • Higher product concentration
  • Low liquid hold up
  • Flexible capacity
  • Low energy consumption


Generally for steep water or corn syrup liquor (CSL) concentration, two types of evaporators are employed: Falling Film evaporator and Plate evaporator, each one has its own advantages.

Falling Film Evaporator

CSL is evenly distributed on the inner surface of some tubes. CSL will flow downwards forming a thin film, from which evaporation will take place because of the heat applied by the steam. The steam will condense and flow downwards on the outer surface of the tubes.

Falling film evaporators can be operated with very low temperature differences between the steam and syrup, they also have very short product contact times, typically just a few seconds per pass. These characteristics make the falling film evaporator particularly suitable for heat-sensitive products. It is today the most frequently used type of evaporator.

Plate Evaporator

During the plate evaporation process, syrup is pumped between thin plates with the heating medium on the mating surfaces. Syrup 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.
