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.

FAQ
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 (reconstituted) 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.
Q: What is your terms of payment ?
A: The buyer shall pay 30% of the contract amount to the seller by T/T as down payment within 10 days after the contract is signed and shall open 120 days. Irrevocable letter at sight of Documentary credit 65% of the contract amount and shall be effected against the presentation of the seller’s drafts drawn at sight, on the opening Bank accompanied with the shipping documents. 5% of contract amount will be paid by T/T to the seller within 10 days against the presentation of signed acceptance letter by the buyer.
