Rising film evaporator new design

Evaporation equipment include wiped film evaporator, rising film evaporator, falling film evaporator, rotary 
evaporator. Today let us discuss the rising film evaporator together.

The rising film evaporator is an evaporator where the feed liquid is preheated to the boiling point, is added 

from the bottom of the heating chamber, and is strongly vaporized in the heating tube, so that the generated 

steam drives the feed liquid to rise in a film shape along the tube wall. 

The heating chamber of the rising film evaporator is composed of single or multiple vertical tubes. The ratio

of the length and diameter of the heating tube is 100-150, and the tube diameter is between 25-50mm. The 

raw material liquid is preheated to reach the boiling point or close to the boiling point, and is introduced into 

the tube from the bottom of the heating chamber, driven by the high-speed rising secondary steam, which 

flows in a film shape along the wall and evaporates while reaching the desired concentration at the top of 

the heating chamber, The completion liquid is discharged from the bottom of the separator.
