Principle:

 mechanical steam recompression (MVR) evaporator uses the secondary steam produced in the evaporator, compression by the compressor, pressure, temperature increase, enthalpy increase, it is then sent to the heating chamber of the evaporator for use as a heating steam to keep the feed liquid boiling while the heating steam itself condenses into water. In this way, the steam that was to be discarded was fully utilized, latent heat was recovered, and thermal efficiency was improved. The economy of raw steam was equivalent to 30 effects of multi-effect evaporation, the utility model reduces the demand for external heating and cooling resources, reduces the energy consumption and reduces the pollution.

Key Features:

 01. MVR energy-saving evaporator technology is the international advanced evaporator technology at present, only a small amount of steam is needed (a small amount of steam is needed when the machine starts up, almost no steam is needed in normal operation) , greatly reduce the cost of enterprise operation, reduce environmental pollution. 

02. Compared with the traditional evaporator, the temperature difference is much smaller, which can achieve mild evaporation, greatly improve product quality and reduce scaling.

 03. No condenser or only a small area of the condenser, the structure and process is very simple, fully automatic operation, continuous operation, safe and reliable. 

04. CIP cleaning pipeline in the equipment, can realize on-site cleaning, the whole set of equipment is easy to operate, no dead angle. 

05. The evaporator evaporates the material at low temperature (50 ° C-100 ° C) and without forming foam, the material liquid is uniform, does not run the material, is not easy to coke, and the material heat denaturation is small. 

07. The traditional multi-effect evaporator uses fresh steam as its energy source. If the five-effect evaporator evaporates 1 ton of water, it generally consumes 0.23 tons of fresh steam. The energy consumed by the MVR mechanical compression evaporator is electrical energy, evaporation of 1 ton of water generally consumption of 15-27 degrees, the general boiling point of materials can rise to a smaller amount of water and electricity consumption of less than 20 degrees per ton. The degree of energy saving is closely related to the unit price of local fresh steam and the price of electricity. For example, the unit price of steam is 180 yuan per ton, and the price of electricity is 0.7 yuan per kilowatt hour compared with the five-effect evaporator, for every ton of water evaporated, energy consumption would be saved by 0.23 * 180.20 * 0.7 = 27.4 yuan. For 100 tons of water evaporated, the annual operating time would be 330 days and the daily working hours would be 24 hours. The annual energy consumption would be 27.4 * 100.24 * 330.21700800 yuan. MVR evaporator than five-effect evaporator energy saving of more than 60% . 

08. MVR mechanical compression evaporator is about twice the price of multi-effect evaporator, for new projects, compare the difference in investment, investment procurement MVR spend more investment is generally within 300 days of operation can be recovered.
