Operating Principle:

 Kadate Evaporation and Crystallization Co., Ltd. produces film蒸发, where the feed liquid is added to the tube box of the film evaporator's heating chamber, distributed evenly through the liquid distribution and film-forming device, and flows uniformly through the heat exchange tubes. Under the action of gravity, vacuum induction, and airflow, it forms a uniform film that flows downward. During this process, the liquid is heated and vaporized by the heating medium in the shell side, and the vapor, along with the liquid phase, enters the separator of the evaporator. The vapor and liquid are then fully separated; the vapor is condensed in the condenser (single-effect operation) or fed into the next evaporator as a heating medium, thereby enabling multi-effect operation. The liquid phase is discharged from the separator. For more information, please call our technical hotline for detailed inquiries.

2Low operating temperature

3Short heating time

4High evaporation intensity

5Great operational flexibility

Main Types:

Single-effect falling film evaporator, multi-effect falling film heat exchangers, etc.

Application Range:

Film Evaporator, suitable for low-temperature concentration in industries such as milk, glucose, starch, xylose, pharmaceuticals, chemical engineering, biotechnology, environmental protection engineering, and waste liquid recycling. It is also widely used for waste liquid treatment in these industries. Particularly suitable for thermosensitive materials, the equipment operates continuously under vacuum and low-temperature conditions, featuring high evaporation capacity, energy saving, low operating costs, and ensuring the material remains unchanged during the evaporation process.
