Falling Film Evaporator
FALLING FILM EVAPORATORS (FFE)
Our aim is to bring benefits to the chemical/process industry with practical advice backed by extensive factory-based knowledge and process automation. We have modified the conventional evaporation systems by modifying the evaporator design, developing efficient bleeding system from the evaporator bodies and developing flashing system with maximum flash recovery thus attaining high energy efficiency & reduced steam consumption. The competent design modification of evaporators helped in achieving various marvelous consequences in chemical / process industry generating peak client satisfaction.

Falling Film Evaporators are generally used to concentrate heat sensitive materials where the stability of the original product properties is very important. These evaporators have long tubes and are most suitable for low temperature applications. They are generally used to handle non-fouling and relatively non-viscous products. In falling film evaporators uniform distribution of liquid in each tube is the most important feature for efficient performance.

SED DESIGNED FFE ARE HIGHLY COST EFFECTIVE WITH OPTIMIZED FEATURE DESIGNING.

TUBULAR FALLING FILM EVAPORATOR TYPES:

  • FFE with external entrainment separator.
  • FFE with inbuilt entrainment separator.

ADVANTAGEOUS FEATURES:

Efficient Distribution of liquid:
Constant wetting of heating tubes with juice is of critical importance for a trouble-free operation of a falling film evaporator. We provide FFE with hi-tech distributor design with the following features:

  • Non-choking distributor design.
  • Easy to clean and maintain.
  • Easy installation and alignment of distributor.
  • Uniform flow in each tube ensuring high wetting rate and increased heat transfer coefficient.
  • Inbuilt recirculation line makes it more compact (optional).
  • Top cover with hinge assembly for easy maintenance of distributor.

Mist Separator: Compact entrainment separator, internal or external depending upon the vapours capacities.

Heating tubes :
  • Corrosion resistant Stainless Steel tubes.
  • Hassle free tube replacement.
  • For optimum steam distribution baffles are provided.

High Heat Transfer Coefficient:Higher heat transfer coefficient due to uniform wetting rate and formation of thin film.

Easy process control with fully automated system: Consistent concentrated product is obtained when equipped with well designed automated control system. Convenient manual or auto online cleaning, troubleshooting and various other features.

Uncomplicated erection:
  • Self supporting structure requiring less floor space.
  • No distributor adjustment required at site.
  • Prefitted with all the accessories.
  • Least erection time at site.
  • Fastest delivery.

STANDARD CONFIGURATIONS AVAILABLE WITH HEATING SURFACE AREA (m2):

1500, 2000, 2500, 3000, 3500, 4000, 6000.
