Freeze Drying Method Explained
Three basic steps define the freeze drying process: freezing, primary drying (sublimation), and secondary drying (desorption).
- Freezing: You have to first freeze the fruit at very low temperatures—usually between -40°F and -50°F. This guarantees the maintained cellular structure of the fruit.
- Primary Drying (Sublimation): The frozen fruit is then put in a vacuum chamber, in which the pressure is lowered. This lets the fruit's ice turn straight into vapor rather than going into the liquid phase. This phase of the freeze drying process is the most important one, as it eliminates most of the water content.
- Secondary Drying (Desorption) This stage consists of gently heating the fruit to eliminate any last moisture. The end effect is a long shelf life and lightweight, crunchy fruit.
