Freeze drying is a drying technology
that uses the principle of sublimation. It freeze the dried material quickly at
low temperature, and then in a proper vacuum environment, the frozen water
molecules are directly sublimated into water vapor and overflow. The substance
is always at a low temperature (frozen state) before drying, and the ice
crystals are evenly distributed in the substance. During the sublimation
process, concentration will not occur due to dehydration, thus avoiding side
effects such as foaming and oxidation caused by water vapor. Freeze-dried
products are spongy, have no shrinkage, good rehydration properties, and low
water content. It can be stored and transported for a long time at room
temperature after being packaged accordingly.
Freeze dryer is suitable
for freeze drying, strain preservation, etc. in biological research, medicine
and pharmaceuticals, chemical industry, food processing, colleges and
universities, etc.
Freeze drying can protect
the activity of heat-sensitive substances, preserve the nutritional value to
prevent oxidation, have no additives, and maintain their freshness for an
extended period of time. The dried substance is loose and porous, sponge-like.
It dissolves quickly and completely after adding water, and almost immediately restoring
its original shape.
