Functional principle
1. The basic principle of the freeze dryer is based on the three-state changes of water. Water has solid, liquid and gaseous states,
and the three states can convert into each other and coexist. When water is at the triple point (temperature is 0.01°C,
water vapor pressure is 610.5Pa), water, ice, and water vapor can coexist and balance each other.
In a high vacuum state, the principle of sublimation is used to make the moisture in the pre-frozen material directly sublimate
into water vapor in the ice state without melting the ice and be removed, thereby achieving the purpose of freeze drying.
Freeze-dried products are sponge-like, have no drying shrinkage, have excellent rehydration properties, and contain very little moisture.
After being packaged accordingly, they can be stored and transported at room temperature for a long time.
Since vacuum freeze drying has unparalleled advantages over other drying methods, this technology has become more and more popular
and concerned since its inception. Applications in medicine, biological products and food have become increasingly widespread.
Biological products such as serum, bacterial strains, Chinese and Western medicines mostly contain some biologically active substances,
and vacuum freeze-drying technology also provides a good solution for preserving biological activity.
2. Freeze-drying is a technology and method that uses the principle of sublimation to freeze-dry. It quickly freezes the dried material at low temperature,
and then directly sublimates the frozen water molecules into water vapor to escape in an appropriate vacuum environment. the process of.
The product obtained by freeze-drying is called lyophilizer, and the process is called lyophilization. The material is always at a low temperature (frozen state)
before drying, and the ice crystals are evenly distributed in the material. The sublimation process will not cause concentration due to dehydration,
and avoids side effects such as foam and oxidation caused by water vapor. The dry substance is porous in the shape of a dry sponge,
ith basically unchanged volume, and is easily soluble in water and restored to its original shape. To prevent physical, chemical and biological denaturation
of dry substances.
