Heat Pump Doulbe Effect Evaporator
Heat pump distiller
Application
This evaporation system embodies an energy-efficient design by recovering residual evaporation heat. It represents a fundamental departure from the linear logic of conventional evaporators, achieving a closed-loop energy cycle. The system transitions the heat source from external steam to an internal Carnot cycle, which captures and reuses the heat contained within the evaporated solvent.
Equipment Structure:
Electric pure evaporation module, preheater, condenser, evaporator, evaporator room, vapor-liquid separator, receiver tank, compressor, pump, system internal pipe fittings and valves, etc.

Working Principle
Within the compressor-driven closed loop, the refrigerant undergoes continuous phase transitions to facilitate heat transfer.
The condensation of the refrigerant provides the thermal energy required for both evaporation and secondary steam condensation.
Conversely, the condensation heat of the secondary steam (produced during feedstock evaporation) is absorbed by the refrigerant during its evaporation phase.
Through this integrated cycle of heat exchange, the system efficiently accomplishes feedstock concentration, solvent evaporation, and solvent recovery.
Features

High Efficiency & Energy Savings
Electrically driven pure technology delivers low specific energy consumption. Low-temperature negative pressure evaporation protects heat-sensitive materials.

Enhanced Safety
Compressor processes refrigerant only-not material vapor-ensuring safe heat exchange without altering the core evaporation process. Explosion-proof construction with interlocking controls.

Smart Modular Design
Fully automated intelligent operation with realtime parameter monitoring. Compact skidmounted module reduces footprint.

Scope of Application
The system is primarily designed for evaporation and concentration of aqueous solutions and organic solvents-such as ethanol, methanol, ethyl acetate, acetone, and n-hexane-as well as for solvent recovery. It is widely applied across the biopharmaceutical, chemical, food, and dairy industries.
