Forced Circulation MVR Evaporator System For Thermal Vacuum Evaporation

New Design Mvr/Tvr Plate-Type Evaporators For Dairy Processing

Description

Mechanical vaporization re-compression system, which is called MVR which principle is to compress the second steam generated by evaporator by high efficiency steam compressor; this process transfers electric energy to heating energy and higher the pressure and temperature of second steam. The second steam with higher temperature will be sent to evaporation room to heat the product for evaporation. So the latent heat of vaporization of the second steam can be circularly used. Making use of less energy which is the mechanical energy of compressor blade wheel as the compression heat pump, energy is added into the heating medium and is circularly used in heating process. Under this circumstance, no need to add first steam as heating medium.

Technical characteristics

◆ Main driven power of MVR evaporation system is electric energy. Electric energy transfer to mechanical energy and improve the quality of second steam which is more economic than produce or purchase fresh steam.
◆ Under most of the evaporation process, system no need fresh steam during operation. Only need some steam compensation for pre-heating the raw material when heat energy from product discharged or mother liquid cannot be recycled due to process requirement.
◆ No need independent condenser for second steam condensation, so no need circulating cooling water. Water resource and electric energy will be saved.
◆ Compared with traditional evaporators, MVR evaporator temperature difference is much smaller, can achieve moderate evaporation, greatly improve product quality and reduce fouling.
◆ Evaporation temperature of system can be controlled and very suitable for evaporation an concentration of thermal sensitive product.
◆ Lowest energy consumption and operation cost,electricity consumption of one ton water's evaporation is 2.2ks/C.
