What is falling film evaporator

Three common equipments for removing solvents and recovering alcohol, wiped film evaporator, falling film evaporator, and rotary evaporator.  Between these three evaporation equipment, falling film evaporators have the characteristics of high heat transfer efficiency, small temperature difference loss, short material residence time, and not easy to deteriorateare, etc.

So falling film evaporators are commonly used to evaporate solutions with greater concentration and viscosity, and are widely used in the evaporation and concentration process of liquid materials in pharmaceutical, chemical, food, light industry and other industries.

The structure of falling film evaporator is composed of evaporator (heat exchanger), separator, preheater, condenser, condensate tank, circulation pump and other components.

• Falling film evaporator can evaporate materials with higher concentration and higher viscosity.
• Because the solution flows like a film in a single-pass evaporator, the heat transfer coefficient is high.
• Short residence time, not easy to cause material deterioration, suitable for processing heat-sensitive materials.
• The falling film evaporator is suitable for evaporating and concentrating foaming materials. Since the material liquid evaporates in the heating tube in the form of a film, the material liquid does not cause much impact during the whole process, avoiding the formation of foam.

So falling film evaporators are commonly used to evaporate solutions with greater concentration and viscosity, and are widely used in the evaporation and concentration process of liquid materials in pharmaceutical, chemical, food, light industry and other industries.
