Freeze drying profess is finished under low temp, especially suitable for heat-sensitive material, can prevent the isolation membrane contraction.
- Vacuum Freeze Dryer
Vacuum freeze dryer is widely used in medicine, pharmacy, biology research, chemical industry and food production, etc. Goods are easier for long-term store after freezing-drying processing, they can be restored to the original state and maintain its chemical and biological characteristics after being watered.
- Freeze drying profess is finished under low temperature, so it’s especially suitable for many heat-sensitive material, can prevent the isolation membrane contraction.
- Drying under low temperature, ther loss of the material’s volatile component is very small.
- Because the material is in the frozen state to dry, so almostly keep the same size, maintained the original structure, enrichment phenomenon will not occur.
- After dry, the material is porous, in sponge state, avoids the vacuum cracking problem of pole piece. After adding water could dissolve quickly & completely, and almost immediately restore the original character.
