- Separation chamber
- Preheater
- Crystallizer
- Condenser
- Vacuum pump
- Material pumps
- Electrical control cabinet

Forced Circulation Design
Our system employs a forced circulation evaporator, balancing:
- High material flow rates (preventing scaling)
- Low motor power consumption (30% less than traditional designs)
- Seamless integration with crystallizers for continuous solvent evaporation, vapor-liquid separation, and crystal growth.
Operational Control Mechanisms
-
Crystal Growth Regulation:
- Internal mother liquor circulation controls crystal growth rate.
- External mother liquor circulation adjusts heat transfer coefficient and supersaturation.
-
Anti-Scaling Measures:
- Precision flow control minimizes wall scaling.
- Crystallizer with overflow function ensures uniform particle size.
-
Enhanced Crystallization:
- Extended legs and 出料 pumps (discharge pumps) transfer crystals to cooling tanks for secondary crystallization.
MVR Evaporator Technical Advantages
-
Exceptional Energy Efficiency:
- 50% less steam consumption by recycling secondary vapor as heating source.
- Low-temperature evaporation reduces thermal energy loss.
-
Compact & Space-Saving:
- 40% smaller footprint than multi-effect evaporators.
- Eliminates need for cooling systems (saves 30% installation cost).
-
Process Optimization:
- Short material residence time (ideal for heat-sensitive substances).
- 10–15% higher concentrate yield than traditional extractors.
- 30% less solvent usage with 50–70% reduced consumption.
-
Operational Flexibility:
- Stable performance under partial load conditions.
- Automated controls reduce manpower by 50%.
