Freeze Dryer

Freeze Dryer – Vacuum Freeze Drying Equipment

A freeze dryer is an advanced drying technology based on the principle of sublimation. The material to be dried is quickly frozen at a low temperature, and under appropriate vacuum conditions, the frozen water molecules directly sublimate into water vapor and are removed. The product obtained through this process is called a lyophilized product, and the process is known as freeze drying.

During the entire drying process, the material remains in a low-temperature frozen state, with ice crystals evenly distributed inside. The sublimation process avoids concentration caused by dehydration, effectively preventing side effects such as foaming and oxidation caused by water vapor. The final dried product presents a porous, sponge-like structure with almost unchanged volume, and can be quickly dissolved in water to restore its original state. This technology greatly prevents physical, chemical and biological denaturation of the dried materials.

Key Features of Freeze Drying

1. Minimal loss of nutritional ingredients. The freeze-dried product maintains a porous structure and appearance similar to its original form.
2. The physical, chemical and biological properties of the material remain basically unchanged after vacuum freeze drying.
3. Effectively preserves the original color, aroma, taste, shape and freshness of food products.
4. Rapid rehydration when exposed to water, with a long storage life in sealed containers.
