Freeze drying technology is widely used in biological engineering, pharmaceutical industry, food industry, material science and deep processing of agricultural and sideline products etc.. So freeze drying technology what are the advantages? Now Qingdao Creatrust Co.,Ltd will supply you sample introduction.
1, in freeze drying process, microbial growth and enzyme function cannot be performed, it can maintain the original nature. Because in the frozen state is dry, so that the volume is nearly constant, maintained the original structure, not concentrated phenomenon.
2, due to drying under vacuum, oxygen is few, therefore some easily oxidized substances are protected.
3, dry can eliminate 95-99% above the water, the post drying product can be stored for a long time without spoilage.
4, the dried material is loose and porous, a sponge, water dissolves quickly and completely, almost immediately to restore the original characters.
5, the freeze dryer at low temperatures, therefore particularly suitable for a lot of heat sensitive material. Such as protein, microbial and so does not occur degeneration or loss of biological activity. So it has been widely used in medicine.
6, in the low temperature drying, material in some loss of volatile components is very small, suitable for some chemical products, medicine and food drying.
Qingdao Creatrust Co.,Ltd main product laboratory freezer dryer (table type and upright type ）and production freeze dryer.
