Falling Film Evaporator
The falling film evaporator is a high-efficiency evaporation equipment. Its working principle is to add the material liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it to each heat exchange tube through the liquid distribution and film forming device. Under the action of vacuum induction and air flow, it flows into a uniform film shape from top to bottom. During the flow process, the material liquid is heated and vaporized by the shell-side heating medium, and the steam and liquid phase generated enter the separation chamber of the evaporator together. After sufficient separation, the steam enters the condenser for condensation (single-effect operation) or enters the next-effect evaporator as The medium is heated, thereby achieving multi-effect operation, and the liquid phase is discharged from the separation chamber.

Introduction to Falling Film Evaporator
The falling film evaporator is an efficient evaporation and concentration device that evaporates by forming a thin film on the inner wall of the heating tube and flowing downward. Its main advantage is that it has high liquid film evaporation efficiency and is suitable for handling heat-sensitive and high-viscosity solutions. Widely used in food, pharmaceutical, chemical and other fields, falling film evaporators can achieve rapid concentration at lower temperatures and reduce heat loss of materials. They are ideal equipment for high-quality product processing.

Working Principle of Falling Film Evaporator
- Liquid film formation: The liquid enters from the upper part of the heating tube, forms a uniform liquid film on the tube wall, flows downward, and gradually evaporates.
- Rapid evaporation: The liquid film is evaporated by heating to form secondary steam, which can be further utilized to improve the thermal efficiency of the equipment.
- Concentrated discharge: The concentrated liquid after multiple evaporations is discharged from the bottom to reach the required concentration concentration.
