Vacuum Freeze Dryer

This vacuum freeze dryer freezes moisture first, then utilizes the principle of sublimation to remove the moisture from pre-frozen materials without going through the melting process of ice. The moisture is directly sublimated from the frozen state to water vapor, thus achieving the goal of freeze-drying. Compared to traditional drying methods, it has advantages such as preserving the original flavor, color, nutrients without loss, and maintaining the original structure.
