Freeze-drying does not destroy the original chemical structure and morphology of the sample

A cryolyophilizer is a technical method
of pre-freezing water-containing items and then sublimating their moisture in a vacuum to obtain dried goods.

Freeze-dried items are easy to store for a long time, and can be restored to the pre-freeze-dried state after adding water and maintain the original biochemical properties
.

For heat-sensitive substances such as antibiotics, vaccines, blood products, enzyme hormones and other biological products, freeze-drying technology can show its superiority
.

Freeze-drying is a technique that uses the principle of sublimation for drying, which is the process of quickly freezing the dried substances at low temperatures, and then directly sublimating the frozen water molecules into water vapor escape under the appropriate vacuum environment.
The product obtained by freeze-drying in a cryophilizer is called lyophilizer, and the process is called lyophilization
.

Lyophilized products of low-temperature lyophilizer are spongy, non-drying, good rehydration, very little moisture, and can be stored and transported
at room temperature for a long time after corresponding packaging.

Freeze-drying equipment, excellent performance, can make the moisture in the food in the pulp and vacuum conditions by the solid state directly sublimated and dried, without liquid evaporation
.

Can maximize the preservation of the original color, aroma, taste, shape, the original nutrients and active substances are rarely destroyed, and rehydration quickly, no need to use preservatives, dried products popular international market energy-saving food freeze-drying machine energy-saving food freeze-dryer, mainly including the material freezing freezer and sublimation dehydration drying warehouse and refrigeration, vacuum, heating and other auxiliary systems
.

Freeze-drying does not destroy the original chemical structure and morphology of the sample, and the biologically active material can still restore the conformational and biological functions
before lyophilization after re-dissolution.

As long as it is watery, non-toxic and non-corrosive, it can be made into lyophilized products by vacuum freeze-drying technology to achieve the purpose of
long-term storage.
