B. owing to being low temperature drying, make nutritional labeling and the fragrance ingredient loss of volatile ingredient in material and heated denaturalization very little, be therefore the high-quality drying means of chemicals, medicine and food.
C. in low temperature drying process, the effect of microbial growth and enzyme almost cannot be carried out, thereby can keep best the original proterties of material.
D. volume after dry, shape are substantially constant, and it is spongy that material is, without drying shrinkage, during rehydration and the contact-making surface of water large, can also become rapidly original shape.
E. because being generally dry under vacuum, therefore oxygen is few, make oxidizable material obtain protection.
F. can remove in material 95%～99.5% moisture, the long shelf-life of goods.
2. the application of freeze-drying
Freeze-drying is a kind of drying means of high-quality.But it needs more expensive special equipment, and the energy consumption in dry run is larger, so processing cost is higher, is mainly used at present the following aspects.
A. biological products, pharmaceutical preparations: as the preservation of antibiotic, antitoxin, diagnostic article and vaccine.
B. microorganism and algae aspect: as the long-term preservation of various bacteriums, yeast, ferment, protozoan, fine algae etc.
C. biological sample, biological tissue aspect: as make various animal or plant specimens, kept dry is for edge tissues such as animal xenogenesis or homoioplastic skin, bone, sustainer, heart valves.
D. make the cell sheet for light microscope, electron scanning and transmission microscopy.
E. the dry aspect of food: as coffee, tealeaves, meat fish eggs, marine alga, fruit, vegetables, condiment, bean curd, instant food etc.
F. senior nutrition and Chinese herbal medicine aspect: as royal jelly, honey, pollen, Chinese herbal and crude drugs preparations etc.
G. the preparation aspect of super fine: as produce the super fines such as Al2O3, ZrO2, TiO2, Ba2Cu3O7～8, Ba2Ti9O20.
H. other aspects: as the catalyst in chemical industry, can improve 5～20 times of catalytic efficiencies after freeze-drying; Plant leaf, soil freeze-drying are preserved, in order to study soil, fertilizer, the effect of weather on the impact of plant growth and the factor; Moist Wooden Cultural Relics, to flood bad books contribution etc. dry by desivac, can maintain the original state to greatest extent etc.
3. cryodesiccated basic process is as follows:
A. the preparation of goods (pre-treatment): as the cultivation of medicine, sterilizing, packing, wash bottle, partly jump a queue etc., the selecting of raw-food material, cleaning, cutting, the enzyme that goes out, packing etc.
B. the freezing of goods (pre-freeze): goods are frozen into solid-state.
C. the first stage is dried (lyophilization): the ice crystal in goods is removed in distillation mode.
D. second stage is dried (adsorption stripping and dry): the moisture that residues in goods is evaporated to a part under higher temperature, make residual moisture reach pre-provisioning request.
E. pack: dried product generally should, in vacuum or filling with inert gas condition lower seal packing, be beneficial to store.
