Our freeze dryer is a dehydration machine that preserves perishable materials by removing moisture through sublimation. This process involves freezing the material and then reducing the pressure to allow the frozen water to change directly from a solid to a gas , without passing through the liquid phase. This gentle process preserves the product's structure, flavor, color, and nutritional value better than traditional drying methods that use high heat.
Key components:
Drying Chamber: Where the product (in trays or flasks) is placed for the process.
Refrigeration System: Cools the product initially and maintains the low temperature in the condenser.
Condenser (Cold Trap): A surface maintained at a very low temperature (e.g., around -50°C to -60°C) to capture and solidify the sublimated water vapor, protecting the vacuum pump.
Vacuum System: Includes a high-quality vacuum pump to lower and maintain pressure in the chamber, enabling sublimation.
Heating System: Controlled heaters (e.g., via heated shelves or ambient heat) provide the necessary energy for the sublimation process.
Control System: Automates and monitors the temperature and pressure throughout the cycle via touch screens and sensors, ensuring optimal drying conditions.
Main applications:
Pharmaceuticals & Biotechnology: Essential for preserving sensitive biological products, such as vaccines, antibiotics, proteins, enzymes, and diagnostic kits, ensuring long-term stability and efficacy without refrigeration.
Food Industry: Used to produce high-quality instant coffee, dried fruits, vegetables, and ready meals that retain their original taste, aroma, and nutritional value.
Laboratories & Research: Ideal for preparing and preserving a wide range of samples for analysis and long-term storage, from cell cultures to archaeological artifacts.
Cosmetics: Preserving active ingredients like collagen and peptides in skincare products to ensure their potency is maintained.
Space Exploration: The lightweight and long shelf-life of freeze-dried food make it ideal for astronaut meals during long space missions.
