Key Benefits of batch freeze dryer
-Low-Temperature Preservation: Prevents thermal degradation, maintaining bioactive compounds (e.g., proteins, vitamins, and volatiles).
-Minimal Structural Damage: Sublimation of ice under vacuum preserves cellular integrity, avoiding shrinkage or hardening.
-Oxidation & Microbial Stability: Near-elimination of water inhibits enzymatic reactions and microbial growth, extending shelf life without preservatives.
-High Rehydration Capacity: Open porous matrix enables rapid and complete water restoration, approximating fresh material properties

Advantage of alternative vapor trap for batch freeze dryer
Vapor trap is built into the bottom of the batch freeze dryer drying chamber and is equipped with a double steam condenser for continuous deicing (CDI).
During the whole freeze-drying process, When the right condenser in the chamber begins to melt ice, the sealing door plate of the condenser in the chamber moves from the left side to the right side to close the right condenser, and the left condenser communicates with the chamber for water vapor capture. The de-icing tank connects the negative pressure water vapor on the right side of the chamber into the right condenser which has been closed by the sealed door, and melts the thin ice collected on the bundle into water, which flows into the de-icing tank through the lower part of the same pipeline. After the right condenser completes the ice melting, it turns to the left side to achieve the alternating ice melting of the two condensers. During the whole freeze-drying process, no additional time is required to melt the ice individually, which helps to increase the capacity of production.

FAQ
How soon can we respond to the customer's inquiry?
Within 24 hours.
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.
