Freeze drying equipment prices for meat, freeze dry meat machine for freeze dried food

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, meat, condiments, aquatic products, biological products, medicine, beverage and etc.

Advantages of Freeze Dried Food

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. 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.
