Fruit Freeze Drying Machine Work Principle

The core principle of a fruit freeze dryer is sublimation. The water in the fruit is converted directly from solid (ice) to gas (water vapor), skipping the liquid phase. The working principle of a commercial fruit freeze dryer machine is based on two core technologies: low-temperature freezing and vacuum dehydration:

1. Pretreatment and quick freezing: Fresh fruit is carefully selected, cleaned, peeled, and pitted. It is then cut and sliced according to product requirements. The processed fruit is then transported to the freeze drying chamber. The temperature is rapidly lowered to below the eutectic point (typically -30°C to -50°C) within a short period of time. The purpose of this rapid freezing is to cause the water within the fruit cells to form tiny ice crystals.This prevents larger ice crystals from piercing the cell walls.
2. Vacuum: Once the fruit is completely frozen solid, a vacuum pump reduces the air pressure in the freeze drying chamber to an extremely low level (typically tens of Pascals). This vacuum causes the triple point of water to change, creating the physical conditions for ice sublimation.
3. Sublimation heat generation: The fruit freeze drying machine uses heating plates to provide controlled, gentle heat to the fruit. After absorbing this heat, the ice crystals sublime directly from a solid state into water vapor. Because the vacuum inside the chamber allows this water vapor to escape unimpeded.
4. Water Vapor Capture: The sublimated water vapor flows to the extremely cold condenser (water trap). There, it recondenses as frost on the condenser’s surface. This continuously separates and captures water from the fruit.
5. Rehydration: After the ice crystals sublime, a porous, sponge-like structure forms within the fruit. The fruit’s volume remains largely unchanged, and upon rehydration, it returns to its original shape.
