Rising Film Evaporator
Our Rising Film Evaporator is designed for efficient concentration of heat-sensitive liquids in chemical and pharmaceutical industries.
The feed is given at bottom of shell & tube type heat exchanger and rises in tubes. Heat is given on the shell side by heating medium. As feed receives heat, vapor generated pushes the liquid on the wall as a film and lifts the liquid upwards. As more vapor is formed, the centre of the tube will have a higher velocity which forces the remaining liquid against the tube wall forming a thin film which moves upwards. The mixture of liquid & vapor are separated at top in vapor- liquid separator.
Frequently Asked Questions (FAQs) –
It is an evaporator where liquid rises inside heated tubes as a thin film to concentrate the solution efficiently.
The liquid enters from the bottom, gets heated, and vapor formation pushes it upward, separating vapor and concentrate at the top.
It works best for low-viscosity and heat-sensitive liquids.
It is used in chemical, pharmaceutical, food, and wastewater industries.
