Product DescriptionWhat is Vaccum freeze dryer ？
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 by freezing 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.
Vaccum 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.
After Freeze Dry
Under vaccum 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.
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.

Q: Why vaccum freeze dried food is so popular?
A: Freeze-drying is a scientific art, combining science and controlled process to result in beautifully preserved food. It retains the most nutrients than any other food preservation method, and maintains its color and flavor. Freeze-drying is also one of the safest methods of food handling used today.
In the food service environment, freeze-dried products require no further handling. They’re ready to eat or be incorporated into products and recipes. In contrast, frozen foods may need to be thawed, then cut, sliced, or diced. Proper thawing measures can stave off pathogen multipliers, but bacteria flourish at room temperature.
Freeze-dried food can help you deliver clean ingredients to consumers. Not only are freeze-dried products easy and versatile, they have a long shelf life and add unique flavor and texture to your new or existing products.
Q: What is freeze drying processing ?
A: 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 by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublime directly from the solid phase to the gas phase.
Q: How many properties of freeze-dried products?
A: If a freeze-dried substance is sealed to prevent the reabsorption of moisture, the substance may be stored at room temperature without refrigeration, and be protected against spoilage for many years. Preservation is possible because the greatly reduced water content inhibits the action of microorganisms and enzymes that would normally spoil or degrade the substance.
Freeze-drying also causes less damage to the substance than other dehydration methods using higher temperatures. Freeze-drying does not usually cause shrinkage or toughening of the material being dried. In addition, flavours, smells and nutritional content generally remain unchanged, making the process popular for preserving food. However, water is not the only chemical capable of sublimation, and the loss of other volatile compounds such as acetic acid (vinegar) and alcohols can yield undesirable results.
Freeze-dried products can be rehydrated (2017 microwave hot sale 1000kg capacity vaccum freeze dryer manufacture of Chinastituted) much more quickly and easily because the process leaves microscopic pores. The pores are created by the ice crystals that sublimate, leaving gaps or pores in their place. This is especially important when it comes to pharmaceutical uses. Freeze-drying can also be used to increase the shelf life of some pharmaceuticals for many years..
Q: Do you provide food samples test? Is it free or extra ?
A: Yes, we could offer the sample test for free charge.
