Rising Film Evaporation Plant

Rising Film Evaporation Plant
The liquid to be concentrated is supplied to the bottom and rises to the top in accordance with the “mammoth pump” or rising film principle. Due to external heating, the liquid film starts to boil on the inside walls of the tubes and is partially evaporated during this process. As a result of the upward movement of the steam bubbles, the liquid is transferred to the top. During the ascent more and more vapours form. The film starts to move along the wall, i.e. the liquid “rising”. The vapours and liquid are then separated in the top-mounted separator.


Particular  feature:
High temperature difference between heating chamber and boiling chamber
High turbulence in the liquid 
Stable high-performance operation


Fields of application:
For large evaporation ratios,for high viscosities and products having a tendency to foul.
Can be used as high concentrator in single pass operation based on extremely short residence times.
