50L Single-Effect Falling Film Evaporator
A 50L single-effect falling film evaporator can be used to evaporate extract liquid under reduced pressure or vacuum condition so that ethanol and liquid material can be separated, condensed and recycled. The single-effect falling film evaporator used for evaporating ethanol solution is different from the one used for evaporating general aqueous solution. The ethanol has a relatively low boiling point, which is volatile. It’s easy to evaporate ethanol solution under reduced pressure or vacuum condition. So it’s relatively difficult to condense and recycle ethanol steam with a smaller evaporation area. Thus the heat exchange area of the condenser is larger. To obtain a better cooling effect, the two-stage or several-stage method is frequently used for cooling and recycling, which also varies from the evaporation of general aqueous solution.
The liquid material is distributed evenly into each falling film tube by distributors and flows downward along the tube wall in the form of liquid film. The liquid material is evaporated during the process of flowing downward under actions of gravity and secondary steam flow. The liquid material and secondary steam are separated basically after reaching the lower part of falling film tubes and separated completely after reaching the separation chamber.

One-Stop Solution Process
A single-effect falling film evaporator is widely used in food, dairy, chemical, pharmaceutical, biological engineering, environmental engineering and deep processing of corn. For example, it is applicable for the evaporation and concentration of aqueous solution, organic solvent solution, fruit and vegetable juice, milk, egg product, vitamin C, collagen, infusion of tea, sodium glutamate and other liquid materials. It is especially suitable for the evaporation and concentration of heat-sensitive materials, because the beneficial elements can be protected to the greatest extent during the heating and evaporation of materials.
