Rising Film Evaporator

Product Description

Rising Film Evaporator

In this type of evaporators feed product enters the bottom of the tubes and steam is introduce from top of the calandria and condensate comes out from the bottom. The ascending force of this steam produced during the boiling causes liquid and vapors to flow upwards in parallel flow. At the same time the production of vapor increases and the product is pressed as a thin film on the walls of the tubes, and the liquid rises upwards. This co-current upward movement against gravity has the beneficial effect of creating a high degree of turbulence in the liquid. This is advantageous during evaporation of highly viscous products and products that have a tendency to foul the heating surfaces.

Applications:

• Fruit Juice concentration.
• Sugar Cane Juice Concentration etc.
