MVR falling film evaporator

1. Introduction Of MVR 
MVR is short for mechnical vapor recompression technology. MVR is an energy saving technology to re-use the second effect steam produced itself as source, then reduce the requirement of outside source. When in early 1960, Germany and France have adopted this technology in fields of chemicals, foodstuff, paper making industry,pharmaceutical, seawater desalination and sewage treatment. In the system of MVR evaporating, use the second effect steam compressed by compressor, pressure, temperature and enthalpy increase, then the steam is transmitted to heater as heating steam, keep the material liquid of system in boiling state, the heating steam changes to condensate water. So the steam that shall be abandoned is full of use, recycle the potential heat, enhance the heat efficiency, the economy of MVR steam is 30times than multi-effect evaporation. 
2. Application range of MVR evaporator 
MVR evaporator is suitable for low-temperature concentration for projects of milk, glucose, organic acid, VC, xylopyranose, pharmaceuticals, chemicals, biologicals, environmental protection. 
3.Components Of MVR Evaporator 
MVR evaporator includes pre-heater, heater, separator, vacuum system, pump, compressor system, automatic control system, cleaning system. 
4 .Features Of MVR 
Advantages of MVR compared with multi-effect evaporator: 
(1)Low energy consumption, low operation expense, when starting, the equipment only needs a little steam, it almost doesn’t need steam when working; 
(2)it needs cooling system and not much public project settings, to save 90% cooled water; 
(3)the occupation scale of equipment is small and the space is also small; 
(4)steady operation, high automation; 
(5) use cleaning source, no any pollution; 
(6)it doesn’t belong to pressure vessel scale, so it doesn’t need supervising and with high security; 
(7)the system equips with CIP cleaning tubes, meets the standard of GMP
