Technical Principles

A falling film evaporator is a vertical high-efficiency evaporation equipment, mainly composed of three parts: a distributor and film-spreading device, an evaporation chamber, and a separation chamber. In the evaporator, the feed liquid is uniformly distributed as a thin film on the inner wall of the heat transfer tubes via the distributor and film-spreading device, and is heated and evaporated while flowing downward.

During the Boiling Process

Performance Advantages

Ultra-thin liquid film (0.1–2 mm):Extremely low thermal resistance, the overall heat transfer coefficient is 50%–80% higher than that of the immersed type.
No boiling point elevation caused by static head:The material does not fill the tube, achieving high utilization of effective temperature difference; s evaporation can be realized at a small temperature difference of only 4–5℃.

Typical Applications

Chemical industry: MVR wastewater, inorganic salt, and polymer solution concentration Food industry:Concentration of milk, fruit juice, coffee, syrup and whey HVAC / Refrigeration: Falling film evaporators for water chillers (high efficiency on refrigerant side)
