The freeze-drying machine is a technical method in which the aqueous article is previously frozen and then the water is sublimated in a vacuum state to obtain a dry product. 

Industrial Freeze Dryer Lyophilizer technology is the most advanced technology for food dehydration processing at present. Compared with the common drying method, the freeze-dried food produced with this technology features long period of quality assurance, good re-hydration nature, good-looking color, good flavor, taste, shape and high content of nutritious components. The dried food basically remains unchanged in its volume and shape, it looks like sponge and has no shrinking. This kind drying technology can be widely used in process of vegetables, fruits, condiments, aquatic products, biological products, beverage and etc.

The freeze-dried article is easy to store for a long period of time, and the water can be restored to the pre-freeze form Keep the original biochemical characteristics.For freeze-drying technology, such as antibiotics, vaccines, blood products, enzymes, hormones and other biological products, can show its superiority, suitable for food,vegatable fruit production.
