Plate Falling Film Evaporator
SEDL proudly presents the Plate Type Falling Film Evaporator (PTFFE), a revolutionary solution designed to redefine evaporation efficiency in sugar processing. With a focus on innovation, excellence, and sustainability, PTFFE offers superior performance while minimizing environmental impact. This advanced solution has the lowest pressure losses and higher turbulence on the liquid side to achieve the highest heat transfer coefficient.By utilizing advanced technology in a user-friendly manner, PTFFE ensures high-quality concentrate production with reduced energy consumption and shorter product residence time.
OperatingPrinciple
Heat Transfer
The evaporator operates on the principle of transferring heat to the liquid to facilitate evaporation.
DISTRIBUTION OF JUICE
Liquid is fed at the top of a vertical tube, forming a thin film that is heated through the tube's surface, facilitating rapid evaporation.
EVAPORATION PROCESS
Liquid is fed at the top of a vertical tube, forming a thin film that is heated through the tube's surface, facilitating rapid evaporation.
ENTRAINMENT SEPARATION
The process involves separating the vapour from the liquid, utilizing mechanical means to achieve efficient separation.
Why IsIt Needed?
Operates at low ∆T (1–4°C), reducing energy use and scale formation.
Preserves quality of heat-sensitive products with short residence time.
Compact, modular design lowers space, installation, and maintenance costs..
Easily scalable by adding or removing plate units for flexible operations.

IndustrialApplications
Higher Efficiency
The short height plate pack/unit patterns and narrow gaps allow for very high turbulence at relatively low fluid velocity and a reduction in vapour piping from one evaporator effect to another.
Lowest ∆T Operation
PTFFE enables evaporation at the lowest ∆T (1-4˚C), which further eliminates the need for high-pressure steam and consequently reduces scale formation
Superior Quality Concentration
Plate evaporator can also be designed for once through operation with suitable design improvement which is not possible in any other type of evaporator.
Flexible Evaporation Rates
A significant benefit of the plate evaporator is that it is expandable; and allows to accommodate more number of effects in given ∆T and ∆P with increased heat transfer capability.
Improved Product Quality
The short heat contact period resulting from single pass operation and low liquid holdup eliminates product
Ease of Maintenance and Cleaning
Due to the plate modular arrangement, the plate unit is easily removed from tie bolts and slides back; the movable plate units then can be inspected,
