is now producing many freeze-dried products, all thanks to the role of freeze-dried . The four-ring freeze-drying experimental lyophilization machine is a cold-drying equipment that can freeze some aqueous substances into solid state, and then sublimate the moisture from solid state to gaseous state to remove moisture and preserve substances. Freeze-drying is a technology that uses the principle of sublimation to dry. It is a process in which the dried substances are quickly frozen at low temperatures, and then under an appropriate vacuum environment, the frozen water molecules are directly sublimated into water vapor escape. Advantages of
Four-ring freeze-drying experimental freeze-dryer.
1. Low-temperature drying is achieved under ultra-low temperature conditions, so many thermosensitive chemicals are especially suitable. Freeze-dryer has been widely used in biomedical , such as proteins, microbial bacterial species, etc.
2. The volume will hardly change, and because it is dry and dry under locking, it maintains the original structure without extracting.
3. The chemical substances dried by the refrigerated dryer are loose and porous structures in honeycomb shape and melt quickly after being released. They are repaired almost immediately.
4. Some chemicals that facilitate air oxidation are maintained, because the freeze-dryer is very dry under the vacuum pump .
5. The freeze-dryer does not cause much damage when the freeze-drying ingredients are dry at lower temperatures, and is suitable for drying some chemical raw materials, drugs and foods.
6. During the entire process of low-temperature drying, the growth and development of microbial bacterial species and the action of enzymes cannot be carried out to maintain the original characteristics.
7. The drying machine can remove more than 95-99% of the moisture, so that the product can be stored for a long time after drying without being easily changed.
8. The carbonate type melted chemicals that were originally melted in water, because the moisture in the raw materials exists in the frost after prefrozen and is evenly distributed in the raw materials;
9. After drying in the refrigerated dryer, the chemicals are loose and porous, and are honeycomb-like. After water release, they melt quickly and thoroughly, and they are almost immediately repaired;
10. Some chemicals that are prone to oxidation are maintained. Because they are dry under vacuum pumps, there are very few O2.
