What are the advantages of vacuum freeze drying techniques?

1. freeze drying at low temperatures, it is especially suited for many heat sensitive substances, can prevent membrane shrinkage.

2. when drying at low temperatures, some of the volatile components of the material are lost very little.

3. because of the drying in the frozen state, the volume is almost unchanged, and the original structure is preserved without condensation.

4. the dried material is loose and porous, which is sponge like, avoiding the problem of vacuum cracking.
