MVR and TVR joint evaporation

For materials with the concentration of higher than 50%, the MVR—TVRjoint evaporation is recommended, which means evaporation and concentration are done in following two steps:

 

  • Step 1: MVR evaporation, which concentrates materials to approximately 50%.
  • Step 2: TVR evaporation, which further concentrates 50% of the intermediary materials until a thick concentration of 70% is achieved.
