Description
MVR Evaporator | Energy-Efficient Low-Temperature Evaporation, Concentration, and Crystallization Equipment
💡 MVR evaporators (Mechanical Vapor Recompression Evaporators) are a new generation of highly efficient, energy-saving integrated evaporation, concentration, and crystallization equipment. Based on the principle of secondary vapor recompression and recycling, they significantly reduce energy consumption and cooling water usage, making them suitable for large-scale, continuous production in industries such as pharmaceuticals, food, plant extraction, chemicals, and high-salinity wastewater treatment.
I. Product Overview
MVR evaporators (Mechanical Vapor Recompression Evaporators) are highly efficient and energy-saving devices for evaporation, concentration, and crystallization. The core principle involves using a compressor to compress and heat the low-temperature, low-pressure secondary vapor generated during evaporation, allowing it to be reused as a heat source in a closed-loop system. Compared to traditional multi-effect evaporation,Energy Consumption Reduction: 60%–90%... with a sharp reduction in cooling water requirements, it is suitable for applications in the pharmaceutical, plant extraction, food, and chemical industries, as well as for the treatment of high-salinity wastewater; it is particularly well-suited for the continuous production of high-concentration, heat-sensitive, and crystallization-prone materials.
II. Structural Configuration Description
The system consists of core components and auxiliary systems. It features a fully enclosed design and is manufactured to sanitary standards, with the entire production line compliant with GMP standards:
✅ Core Component: Steam Compressor
Available in three models—centrifugal, Roots, and magnetic levitation—this unit serves as the core component of the entire system’s closed-loop energy cycle, providing a stable source of thermal power.
✅ Main Evaporation Equipment
There are two types of designs: falling-film and forced-circulation. The falling-film design is suitable for heat-sensitive materials, while the forced-circulation design is suitable for complex materials that are highly viscous, prone to scaling, or prone to crystallization.
✅ Separate condensation system
Equipped with a high-efficiency gas-liquid separator, plate-type/tubular condensers, and a condensate collection tank, the system enables precise gas-liquid separation, heat recovery, and the collection and reuse of condensate.
✅ Material Circulation and Vacuum Systems
It consists of a material recirculation pump, a waste heat preheater, a vacuum pump, and a vacuum tank. It preheats the material in advance, recovers waste heat, reduces energy consumption, and stabilizes the vacuum low-temperature evaporation environment.
✅ Intelligent Automatic Control System
PLC control cabinet + touchscreen visualization, supporting fully automatic interlocked control of temperature, pressure, liquid level, and flow rate; can be integrated with a CIP (Clean-in-Place) system to enable unattended production.
III. Key Features
✅ Maximum energy efficiency, low operating costs
Powered entirely by electricity, it requires no fresh steam during normal operation, with energy consumption per metric ton of water evaporated ranging from just 23 to 70 kWh. Compared to traditional multi-effect evaporation (150–300 kWh), this system achieves energy savings of 60%–90%, significantly reducing production costs for enterprises.
✅ Gentle evaporation at low temperatures protects heat-sensitive materials
Low-temperature evaporation at 50–80°C in a vacuum environment prevents high-temperature oxidation, carbonization, and loss of components in the material, making it ideal for concentrating heat-sensitive materials such as traditional Chinese medicine extracts, fruit juices, and enzyme preparations.
✅ Extremely adaptable to various operating conditions
It can effectively process materials with high salt content, high viscosity, or a tendency to crystallize or form scale. A single unit can handle both concentration and crystallization processes, making it suitable for complex production conditions across multiple industries.
✅ Water-saving and eco-friendly; resources can be reused
It significantly reduces the cooling water consumption of traditional equipment, and the resulting condensate is of such high purity that it can be directly reused in production, thereby conserving water, reducing energy consumption, and promoting environmental sustainability.
✅ Fully Automatic Smart Operation
The entire process is controlled by a PLC system, which supports remote monitoring and automatic parameter adjustment, enabling 24/7 unattended continuous production with stable operation and low labor costs.
✅ Meets hygiene standards and is suitable for high-end production
Available in 304/316L stainless steel or titanium; the equipment features a mirror-polished finish with no blind spots and supports CIP (Clean-in-Place) cleaning, fully complying with GMP and food safety production standards.
IV. Scope of Application
✅ Pharmaceutical Industry
Concentration and crystallization purification of liquid medications such as traditional Chinese medicine extracts, oral solutions, antibiotics, and vitamins.
✅ Botanical Extract Industry
Plant essential oils and natural active ingredients are concentrated at low temperatures to maximize the protection of heat-sensitive active compounds.
✅ Food Industry
Low-temperature concentration and preservation of food ingredients such as fruit juices, syrups, dairy products, fermented liquids, and honey.
✅ Chemical / Environmental Protection Industry
Volume reduction treatment of RO concentrate and high-salinity industrial wastewater; concentration of chemical intermediates; and salt recovery through crystallization.
