How Freeze Drying Works
Principles of Freeze Drying
In essence, Freeze Drying is a dehydration process that enables the preservation of perishable material. It operates primarily on three principles – freezing the product, reducing surrounding pressure, and then removing the water by sublimation.
During sublimation, frozen water molecules directly change from solid (ice) to gas (vapor), skipping the liquid state. This process helps in maintaining the physical structure of the food, preventing shrinkage, and thus preserving texture and flavor.
Stages of Freeze Drying Process
The complete freeze-drying process unfolds in three main stages: Freezing, Primary Drying, and Secondary Drying.
- Freezing Stage: The food product is rapidly frozen at low temperatures. This forms large ice crystals within the product, which aid in a more efficient drying process.
- Primary Drying: During this stage, as much as 95% of the water in the food is removed through sublimation.
- Secondary Drying: The purpose of this stage is to eliminate any residual water left in the product after the primary drying phase.
