Vacuum freeze drying process
1. Frozen original material first,
2. Ensure the condition of vacuum and adequate heating, then the water will be removed from frozen product by sublimate,
3. Finished product will maintain frozen state and biological structure.

FAQ:
How long is the production time of Seasoning vacuum freeze dryer?
It is 120-150 days in Europe and the United States, and 90-120 days in other regions.
Retains nutrients: Freeze-dried food retains up to 97% of its nutrients, including vitamins, minerals, and antioxidants. Long shelf life: Freeze-drying removes the potential for bacterial growth, so freeze-dried food can last for years. Maintains flavor and texture: Freeze-drying preserves the original shape, flavor, and texture of food. Sustainable: Freeze-drying reduces food waste and transportation and storage costs.
Freeze drying works by first freezing a substance, then lowering the pressure around it to a vacuum, which allows the frozen water to directly transition from a solid (ice) to a gas (water vapor) through a process called sublimation, effectively removing the water content without going through a liquid phase, thus preserving the material's structure and properties; this is often used to preserve food, pharmaceuticals, and biological samples by significantly extending their shelf life.
We Dalian Iceberg produce and supply freeze drying equipment with the below types and sizes: 1)Type: Industrial scale of freeze dryers with internal assembly of vapor trap(s) with separate condensers performing the functions of alternative vapour trapping and de-icing Sizes: A50, A75, A100, A125 and A200 2)Type: Pilot Freeze-dryers with one-time condenser Size: A5, A10, A20, A30 We can also develop other model of pilot freeze-dryers according to customer’s demands
