Core Operating Principles
1. Vacuum Evaporation Principle
Operating under low-pressure conditions reduces the boiling point of liquids. Under a vacuum of -95 to -97 kPa, the boiling chamber maintains a highly efficient temperature of 35–37°C. This negative pressure enables automatic suction of raw materials directly into the chamber, saving energy while ensuring optimal performance.
2. Compressor System Principle
A Freon-based compressor system facilitates heating and cooling. Notably, the system eliminates the need for a feeding pump—materials are drawn into the boiling chamber, transferred to a heat exchanger, and water is evaporated. A forced circulation pump ensures continuous atomization, while the evaporation chamber’s liquid level is auto-regulated. Once concentration targets are met, a built-in device discharges the concentrated liquid.
