MVR is the abbreviation of Mechanical Vapor Recompression. It takes use of the compressor to re-compress the second vapor (low temperature and low pressure) which is evaporated from the liquid material, to rise its temperature and pressure, so as to reuse it as heating source to evaporate the liquid material again.

During the evaporation of normal multi effect evaporator, the second vapor of one effect could not be used as the heating source of its own effect, can only be used for the other effect. If want to use for its own effect, must provide extra energy to increase its temperature(pressure), and the steam jet pump can only compress part second vapor, while MVR Evaporator can compress all the second vapor inside the evaporator.

The evaporation process of MVR is low temperature steam compressed by compressor, temperature and pressure increase, increase in enthalpy, and then enters the heat exchanger in order to take full advantage of the latent heat of steam. Apart from the drive started, the entire evaporation no need steam. MVR evaporator from Chengdong Medicine Machine adopts digital intelligent automatic control Product, automatic control system uses high reliability of the Germany Siemens equipment. Use high efficient and high quality compressor to improve the heating efficiency, it is energy-saving at the same time the Product efficiency goes beyond traditional concentration equipment.
