Plate Type Concentrator
Plate falling film evaporator has the lowest pressure losses, the compact design having lower footprint area and higher turbulence on the liquid side with the highest heat transfer coefficient.
Plate Type Falling Film Evaporator (PTFFE) is efficiently developed for optimizing evaporation of sugar solutions with full utilization of the heat transfer surfaces.
PTFFE has the lowest pressure losses and higher turbulence on the liquid side to achieve the highest heat transfer coefficient. Due to the very high heat transfer rate of these evaporators, evaporation from a sugar solution at very low △T can be easily accomplished. It provides flexible capacity merely by adding more plate/units, shorter product residence time resulting in a superior quality concentrate, a compact design with a low installation cost.
PTFFE is the most advanced tool which completely reformed the bleeding scheme and backpressure requirement of the evaporator set. PTFFE is suitable for heat/temperature sensitive material. During the plate evaporation process, the liquid is pumped between thin plates with the heating medium on the mating surfaces. The product is then evaporated with vapor generation forming a high-velocity core. This expansion in volume causes high velocity, thin film on the heat exchange surface providing efficient heat transfer.
