The feed is concentrated up to 45-48% solid concentration in Multiple Effects Falling Film Evaporator with Thermal Vapor Recompression System (T.V.R). Evaporation of water takes place under vacuum conditions and at low temperature.
A Five Effect Falling Film Evaporator with TVR over 3rd effect will have specific steam consumption of 0.12 kg/kg whereas a seven effect plant with TVR over 4th effect gives specific steam consumption of 0.09 kg/kg which is equivalent to energy consumption in MVR (mechanical vapor re-compression )evaporator.
Advantage of Sahiba Fabricators Evaporator is:
- Compact design and flexibility in operation
- Energy conservative design of powder plant.
- Lower requirement of Steam, power and cooling water requirement.
- No scale formation in tubes needs only CIP from balance tank for cleaning.
- Fewer breaks down time.
