THE MVR PROCESS

The temperature of the resulting process steam (vapor) is increased with a radial fan (mechanical vapor recompressor, MVR), and therefore to a higher energy level, and then fed back into the process as fresh heating steam. The energy contained in the steam is not lost; only the energy required to increase the temperature must be additionally raised.

The closed process enables to evaporate temperature-sensitive fluids such as milk in high vacuum at approx. 60 °C and even blood plasma at 35 °C. Valuable components for the end product (e.g. milk powder) remain unaffected and thus increase the quality and value of the product.

MVR Technical Principles
Mechanical Vapor Recompression (MVR) is a proven energy-saving evaporative concentration technology, which reduces evaporation energy use by 90% or more.

MVR uses energy recovered from the condensate to create a pure liquid distillate and a concentrated product/waste.

From Boyle’s law it is known for a gas that PV/T (Pressure * Volume / Temperature) is constant (PV/T=K). During compression of vapor, the pressure and temperature increase. From this, the heat energy can be reused.
The energy normally lost in the compression is recovered, leading to a highly-efficient evaporation process.
Since this compression is realized by a simple mechanical compressor, the process is called MVR

Equipment Structure
Double-effect forced circulation evaporator is composed of heater, separator, vapor-liquid separator, condenser, vacuum pump, forced circulation pump, discharging pump, condensate pump, electrical cabinet, operation platform and all the pipe fittings, valves, instruments and etc.
Heater: Two sets of vertical type tubular heater connect in series. The feed liquid is pumped into the first heater by forced circulation pump, then enters into the second heater. The heated liquid flow downwards in tubes, and flow into separator by tangential direction, better performance of vapor-liquid separation.
Separator: Vertical type, the secondary steam is discharged from the top, pass through a vapor-liquid separator before entering into condenser. The bottom of separator is connected with a forced circulation pump.
Vapor-liquid separator: Is used to prevent tiny liquid drops produced during evaporation from escaping with secondary steam, reducing loss of feed liquid and prevent pollution to pipeline and cooling water.
Condenser: Condensate the huge secondary steam produced during evaporation into liquid by cooling water, making concentration carrying on smoothly. Meanwhile, separate non-condensable vapor from secondary steam and cooling water, make it easily pumped out by vacuum pump to guarantee vacuum degree.

Application

Distillation
During distillation, liquid mixtures of substances with different vapor pressures and boiling temperatures are separated. Examples include distillation of alcohol, or the recovery and purification of solvents.

Concentration
Evaporation produces a concentration of the substance being processed. In applications such concentrated milk or fruit juice production, evaporative systems are also used as a precursor to dryers in the food industry.

Crystallization
During the crystallization process, substances are separated from one another by using different solution equilibria. Applications include salt extraction and fertilizer production.
