Falling film evaporator is widely used for concentration of solutions in dairy product industry, food industry, fruit juice industry, beverage, chemical industry, environmental protection industry, pharmaceutical industry and etc, also is used for sewage treatment of relative industries. 

It is operated continuously under vacuum and low temperature condition, with features of high evaporation capacity, low energy consumption, low operating cost and could keep the original color, flavor and active ingredient maximize. 

Particular features 

1 Best product quality due to gentle evaporation, mostly under vacuum, and extremely short residence times in the falling film evaporator. 

2 High energy efficiency due to multiple-effect arrangement or heating by thermal or mechanical vapour recompressor, based upon the lowest theoretical temperature difference. 

3 Simple process control and automation due to their small liquid content falling film evaporators react quickly to changes in energy supply, vacuum, feed quantities, concentrations, etc. This is an important prerequisite for a uniform final concentrate. 

4 Flexible operation quick start-up and easy switchover from operation to cleaning, uncomplicated changes of product.
