The basic principle is in high vacuum condition, using the
principle of sublimation, the pre frozen material in the water, not
after the melting of the ice, ice sublimation is directly to the
water vapor is removed, so that the material drying, vacuum freeze
drying products can ensure the nutrition of protein, vitamins and
other food, especially the volatile loss of heat sensitive
components. It can maximally keep the original nutrients,
effectively prevent oxidation during the drying process, the
transformation and change of state nutrition, freeze-dried products
into sponge, no shrinkage, rehydration, excellent edible
convenience, moisture content is few, the corresponding packaging
at room temperature can be kept for a long time and transport.
Application scope:
The food industry: vacuum freeze drying technology can be used for
fruits and vegetables, meat, aquatic products, condiments,
convenient food and high quality products such as drying, can keep
food original color, flavor and taste, shape and freshness of the
same purpose, and the rehydration of special product, easy storage
and transportation, reduce the cost, save time extended.
Nutrition and health:
in the dry sea cucumber, Cordyceps, ginseng, royal jelly, turtle,
turtle, earthworms and other nutritional health products, vacuum
freeze-drying technology, more people believe that the pure natural
nutrition.
Pharmaceutical industry:
vacuum freeze-drying method can be applied to serum. Plasma,
vaccines, enzymes, antibiotics, hormones and other Chinese and
Western medicine dehydration and preservation.
Biological research:
the use of vacuum freeze drying technology for long-term
preservation of blood, bacteria, artery, bone, skin, cornea, nerve
tissue and organs, in use only supply water can be recycled, still
maintain its biochemical physical properties.
As in other aerospace insulation ceramic products, Mubo preserved
in archaeological specimens, application of preparation of special
materials, can receive a unique effect
