Product Description:

The working principle of a vacuum freeze dryer (also known as a lyophilizer) involves several key phases that preserve food or other materials by removing moisture under low-pressure conditions. Here’s a breakdown of the process:

1. Freezing:
Initial Preparation: The material (e.g., food) is first prepared by cleaning, slicing, or cooking as necessary.
Rapid Freezing: The material is loaded into the freeze dryer and rapidly frozen to a temperature typically between -40°C to -80°C (-40°F to -112°F). This step ensures that the moisture in the food forms small ice crystals, which helps maintain the food's structure.
2. Vacuum Creation:
Once frozen, the chamber is evacuated to create a vacuum. This significantly lowers the atmospheric pressure around the frozen material, which is crucial for the next phase.
3. Sublimation (Primary Drying):
Controlled Heating: The temperature of the frozen material is gradually increased under vacuum. This causes the ice to sublimate, meaning it transitions directly from a solid to a gas without becoming liquid.
Removal of Vapor: The water vapor produced during sublimation is continuously removed from the chamber by a vacuum system. This allows for effective drying while minimizing the risk of melting the food.
4. Desorption (Secondary Drying):
After primary drying, some moisture may still remain in the material. This phase involves further heating to a slightly higher temperature to remove the residual moisture.
The process ensures that the water content

5. Cooling and Packaging:is reduced to a level that allows for long-term storage and shelf stability.

Once the drying process is complete, the vacuum is released, and the material is cooled rapidly to prevent moisture reabsorption.
The freeze-dried products are then packed in airtight containers or vacuum-sealed bags to protect them from moisture and extend shelf life.
