To meet the increasing demand for energy-saving and efficient concentration technologies, our company has developed the MVR Forced Circulation Evaporator, a low-consumption and energy-saving concentration and crystallization equipment designed for industrial evaporation applications.
With the advantages of fast liquid flow rate, high evaporation efficiency, and reduced scaling tendency, the MVR forced circulation evaporator is especially suitable for high-viscosity liquids, scaling-prone materials, and salt solution crystallization processes.
By utilizing mechanical vapor recompression technology, the system effectively recycles secondary steam and reduces external steam consumption, providing a more efficient and sustainable evaporation solution for chemical, pharmaceutical, food, and wastewater treatment industries.
The MVR forced circulation evaporator consists of an evaporator separator, heat exchanger, and forced circulation pump.
During operation, the material is heated inside the heat exchanger tubes by steam outside the tubes. Under the action of the circulation pump, the heated material enters the evaporator separator.
Due to the reduction of static pressure inside the evaporator separator, part of the material evaporates and generates secondary steam. The secondary steam escapes from the liquid, while the concentrated material reaches a supersaturated state, promoting crystal growth.
After removing supersaturation, the material returns to the forced circulation pump and enters the heat exchanger again. This process continues continuously, allowing repeated evaporation, concentration, or crystallization.
The crystal slurry is discharged from the circulation pipeline through a discharge pump.
The secondary steam generated in the evaporator separator passes through the separation and defoaming device for purification before entering the compressor. The compressor compresses the secondary steam and sends it to the shell side of the heat exchanger as heating steam, realizing continuous evaporation through thermal energy recycling.

Heating chamber
Evaporation and crystallization chamber
Heat exchanger
Forced circulation pump
Condenser
Vacuum and drainage system

The integrated design ensures stable operation, convenient maintenance, and efficient evaporation performance.
The complete system features a reasonable and compact design, stable operation, and low energy consumption.
With forced circulation technology, materials with higher viscosity can flow smoothly through the system, improving evaporation efficiency and shortening concentration time.
The secondary steam recycling system significantly reduces steam consumption and improves thermal energy utilization.
The special design allows simple switching and adjustment of evaporation effects, enabling the equipment to adapt to different production requirements.
This flexibility makes the system suitable for various concentration and crystallization processes.
The evaporation process operates at relatively low temperatures, allowing heat energy to be fully utilized.
The gentle heating process reduces thermal impact on materials and makes the equipment suitable for concentrating heat-sensitive products.
Through forced circulation, the material is heated evenly inside the tubes.
The advantages include:
High heat transfer coefficient
Prevention of dry wall phenomenon
Reduced scaling risk
Improved equipment operating stability
The high flow velocity inside the heating tubes helps maintain efficient heat exchange performance.
After evaporation, the material enters the separator for further separation.
This improves the separation effect and provides the entire system with greater operational flexibility.
The MVR forced circulation evaporator supports continuous feeding and discharge.
The liquid level and required concentration can be automatically controlled, improving production consistency and reducing manual operation requirements.
