Vegetable Freeze Dryer is a batch freeze dryer and active freeze dryer specifically designed for vegetables. Featuring automatic operation,
Here is a step-by-step overview of the freeze-drying process:
1.Freezing: The material to be dried is first frozen. Typically, this is done by lowering the temperature below its freezing point. Freezing converts the water in the material from a liquid state to a solid state (ice). The freezing process helps retain the structure and integrity of the material.
2. Vacuum: Once the material is frozen, the freeze dryer creates a vacuum environment. The vacuum reduces the pressure inside the drying chamber, lowering the boiling point of water and facilitating sublimation. The lower pressure helps prevent the ice from melting and instead allows it to transition directly from a solid to a gaseous state.
3. Sublimation: Heat is applied to the frozen material, usually through heated shelves or coils. This heat energy causes the ice to undergo sublimation, where it changes directly from a solid to a vapor without passing through the liquid phase. The water molecules in the frozen material gain enough energy to break free and transition into a gaseous state.
4. Condensation: As the water vapor sublimates from the frozen material, it needs to be removed from the drying chamber to prevent reabsorption. The water vapor is transferred to a condenser, which is cooled to very low temperatures. The water vapor condenses on the condenser surface, forming ice, and is collected as liquid water.
5. Final drying: After most of the water has been removed through sublimation and condensation, a secondary drying phase may be conducted. This step involves raising the temperature slightly to facilitate the removal of any remaining moisture from the material. The duration of this step can vary depending on the specific requirements of the drying process.
