Falling film evaporator 


Falling film evaporator basic working principle

The feeding liquid will flow into the tubular falling film evaporator from the upper part of the heater, the feeding liquid flows down along the heater surface by the liquid distributor, By gravity and airflow effect, the feeding liquid flows from top to bottom, and be evaporated. After then the vapor-phase and liquid-phase flow into separator together, The separator will separate the vapor and liquid totally, consequently bring about the secondary vapor and concentrated liquid.
For increasing the concentration of the discharging liquid, even avoiding fouling drywall condition, forced circulation falling film evaporator applied in such situation. That's saying to equip forced circulation pump to falling film evaporation system. 


Evaporator System components

Evaporator, separator, condenser, vacuum and discharging system, delivery pump, PLC, electrical appliance and instruments, valves, pipelines etc.


Falling film Evaporation concentration equipment

The Live steam as the thermal energy for heating the first effect evaporator then generates secondary vapor which drawn into the second effect evaporator and so on. The multiple evaporators attached to form the whole multiple effect evaporation system. The latent heat will be recycled and reused, thus reducing the energy consumption and enhance thermal efficiency.


Features

  • The classic popular evaporation and concentration equipment.
  • As the effects increased, the more vapor energy shall be saved.
  • Lower up-front investment, but a large amount of vapor energy consumption bring about a strong energy consumption intensity.
  • It's suitable to use in low-cost vapor energy field.
  • Friendly to the concentration of thermally sensitive material.


Application Range

Solution for concentration. Garlic juice concentration.
