Industrial Xinyang Atlas Vacuum Freeze Dryer With Vacuum Pump for food freeze drying machine
Freeze-drying—technically known as lyophilisation, lyophilization, or cryodesiccation—is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works byfreezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimedirectly from the solid phase to the gas phase.
Vacuum freeze drying 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, medicine, beverage and etc.

Under vacuum condition, material is freeze dried via principle of sublimation. The moisture in the pre-frozen material is directly sublimed from solid state (ice) to gaseous state (vapor), without melting. Freeze dried products are formed to be sponginess, without shrinkage and excellent in rehydration, containing little water only. The freeze dried product in sealed packaging can be stored and transported at room temperature for a long time.

Advantages of Freeze Dried Food
2. Look fresh Freeze-dried foods maintain their original shape and texture, unlike dehydrated foods, which shrink and shrivel due to high-temperature processing. Freeze-drying removes water under low temperatures which keeps intact the moisture channels and food fibers. Just add water, and in minutes every fresh food detail returns.
3. Weigh less than fresh Freeze-dried foods have 98% of their water removed. This reduces the food's weight by about 90%. Because of its light weight per volume of reconstituted food, freeze-dried products are popular and convenient for hikers. More dried food can be carried per the same weight of wet food, and remains in good condition for longer than wet food, which tends to spoil quickly. Hikers reconstitute the food with water available at point of use.
4. Stay fresh Freeze-dried foods can be stored at room temperature, without deterioration or spoilage. This is because freeze-drying and packaging remove both water and oxygen - the two primary causes of food deterioration.
Advantages of Our Freeze Drying Equipment
1. Efficient in heating plates. The material of heating plates is aviation aluminum after being anodized on the surface, releasing over 100% heat from the product by radiation. This makes heat more uniform and complete.
2. Alternate vapor trap. Double trap is installed under the heating plates in drying chamber. Trap 1 condenses vapor to its maximum cpacity, then trap 2 starts to work. In the meantime, trap 1 begins to melt ice for another condensation cycle.
3. Continous de-icing. When the trap 2 begins to catch vapor, the trap 1 begins to melt ice on the coil during drying. After melting, the clean coil is ready for another condensation cycle.
4. Automatic control system. Advanced intelligent control system keeps the system running stably and reliably in a long time. Furthermore, simple operation can be much easier to handle.
