What is 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.

Working Princple of Freeze Drying Machine

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 Our Freeze Drying Equipment

1.Two cold traps
continuous work, continuous vapor trapping
Denmark atlas technology. continuous de-icing system(CDI system)

2. 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.

3.Reflection plates
The upper, lower, left, and right sides of the heating plate have reflector plates to ensure that all heat is used in the material.
Concentrate all the heat on the products, accelerate the products freeze-drying, reduce energy consumption, shorten the freeze-drying time.

4.Heating method :Double side radiation

There is a certain distance between the tray and the heating plate, not directly accepted, the product is heated evenly. good quality.

5. 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. So save human resources. About fully automatic display screen, We can design it according to your requirements.

6.Prodct tray

The loading capacity of the normal tray is 5KG, but the maximum loading capacity of our tray can reach 9KG, only the time of freeze-drying will be extended appropriately.

7.De-icing system

save water:The water used to melt ice comes from the products.

save energy consumption:Our equipment uses negative pressure steam melting ice, So, water is converted to steam when 15 ℃, Then melt the ice.

Advantages of Freeze Dried Products

1. Taste fresh Freeze-dried foods, like frozen, retain virtually all their fresh-food taste and nutritional content. Freeze-drying removes the water, not the flavor.

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.
