Freeze drying is a process in which water is frozen, followed by its removal from the sample, initially by sublimation (primary drying) and then by desorption (secondary drying). Freezedrying is a process of drying in which water is sublimed from the product after it is frozen. It is a drying process applicable to manufacture of certain and biologicals that are thermolabile or otherwise unstable in aqueous solutions for prolonged storage periods, but that are stable in the dry state.

5.Low operating current and low energy consumption
6.Solid stainless steel sample tray and chamber reliable for sample safety and easy for cleaning.
7.Clear organic glass door with direct observation of sample processing
8.Optional: stainless steel exterior and oil-free vacuum pump
2. When drying at low temperature, the loss of some volatile components in the substance is very small, which is suitable for drying some chemical products, and food.
3. In the freeze-drying process, the growth of microorganisms and the role of enzymes can not be carried out, so the original sex suit can be maintained.
4. Because it is dried in the frozen state, the volume is almost unchanged, the original structure is maintained, and the concentration phenomenon will not occur.
5. The dried material is loose, porous and spongy. After adding water, it dissolves rapidly and completely, almost immediately restoring its original properties.
6. As the drying is carried out under vacuum, there is very little oxygen, so some easily oxidized substances are protected.
7. Drying can remove more than 95-99% moisture, so that the dried products can be stored for a long time without deterioration.
Freeze dryer is a small vacuum freeze dryerIt is suitable for lab use and small amount of freeze-dried useIt is widely used in freeze-drying of fruits , vegetables , meat , health care products , etcFreeze-dried food and medicinal materials are easy to be stored for along time , which can retain the taste , nutritional content and shape ofthe original material to the greatest extent.
