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

FAQ
How freeze-drying works?
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.
Delivery Vacuum Freezer Lyophilizer

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.
