Mechanical MVR Evaporation System Vapor Recompression Vacuum Machine

The Mechanical Vapor Recompression (MVR) evaporation system is a vacuum-based machine designed for concentrating and crystallizing high-salinity or heat-sensitive solutions. By mechanically compressing secondary vapor and recycling it as the heating medium, the system delivers exceptional energy efficiency, low operating costs, and continuous stable performance.

Widely used in chemical, pharmaceutical, food processing, environmental, and salt industries, the MVR vacuum evaporator is ideal for:

• Brine concentration and salt crystallization
• High-COD wastewater zero liquid discharge (ZLD)
• Pulp black liquor treatment
• Value-added product recovery

• Feed preparation: Includes pre-filtration, softening, and deaeration
• Evaporation under vacuum: Forced circulation with precise ΔT control for optimal performance
• Mechanical compression: Vapor recompression provides heat energy
• Crystallization: Controlled supersaturation ensures desired crystal size
• Solid-liquid separation: Centrifugation, drying, and mother liquor recycling

• MVR forced-circulation evaporator/crystallizer with circulation pumps
• Mechanical vapor compressor (turbo/Roots) with VFD and protection systems
• Vapor-liquid separator, heat exchangers, condensers, and vacuum system
• Automation controls with PLC/HMI/SCADA for continuous operation
• CIP skid and anti-scaling dosing system for extended uptime

*Performance depends on feed quality, compression ratio, and heat-exchanger design.
