ustrial Falling Film Evaporator for Heat-Sensitive Materials & Solvent Recovery
The DJM new design falling film evaporator is a high-efficiency single effect falling film evaporator designed for continuous concentration, solvent recovery, and low-temperature distillation of liquid materials.
It is widely used in the pharmaceutical, traditional Chinese medicine (TCM), food, beverage, chemical, and light industries, especially for heat-sensitive materials that require gentle evaporation to preserve active ingredients.
This advanced vacuum falling film evaporator also provides efficient ethanol recovery with a recovery rate of ≥95% and final ethanol concentration of ≥90°, making it ideal for industrial solvent recycling systems.
Why Choose DJM Falling Film Evaporator?
Our industrial falling film evaporator is engineered for performance, efficiency, and stability:
- Suitable for heat-sensitive materials
- High ethanol recovery efficiency (≥95%)
- High ethanol output concentration (≥90°)
- Compact and flexible design for easy installation
- 2-in-1 system: concentration + solvent recovery
- Low-temperature evaporation for product protection
Working Principle of Falling Film Evaporator
In this falling film evaporation system, liquid material is evenly distributed from the top of the heating chamber and forms a thin film along the inner wall of the vertical tube.
As the film flows downward by gravity:
- It is continuously heated by the heating medium
- Evaporation occurs instantly in a vacuum environment
- Vapor rises into the separation system
- Condensate is collected and automatically discharged
- Concentrated liquid is discharged from the bottom
This design ensures short residence time, high heat transfer efficiency, and minimal thermal degradation.
