A “Falling Film Evaporator” is a highly efficient heat transfer system used to concentrate liquids in various industrial processes. At Mehar Engineering, we provide reliable evaporation solutions designed for maximum performance, energy efficiency, and consistent product quality.
The process begins by pumping the material liquid to the top of the heating tubes. The liquid flows downward as a thin film along the inner walls of the tubes while heat is applied from the outside. As the liquid travels downward, it gradually boils and partially evaporates. The remaining liquid and vapor are then separated in the next stage of the process.
The controlled flow of the liquid ensures the ideal film thickness, preventing the tubes from becoming excessively dry. This results in excellent heat transfer, reduced energy consumption, and efficient evaporation performance. The system is suitable for both single-pass (one-way) evaporation and recirculation (cyclic) evaporation processes.
Key Features
- High heat transfer efficiency
- Low power and energy consumption
- Uniform liquid film for consistent evaporation
- Suitable for continuous industrial operation
- Supports both cyclic and one-way evaporation
- Reliable performance with minimal scaling
Applications
The Falling Film Evaporator is widely used in food processing, starch production, chemical processing, pharmaceutical manufacturing, and other industries where gentle and efficient liquid concentration is required. It is especially suitable for:
- Heat-sensitive materials
- Low-concentration liquids
- Liquids with low solid content
- Materials with minimal scaling tendency
A single unit can handle processing capacities of up to 200 tons per hour, making it an ideal solution for medium and large-scale industrial operations.
