Working principle of vacuum freeze dryer:

Instead of traditional vaporization dehydration method, the vacuum freeze drying technology is dehydrate products by sublimation directly from ice to vapor. During the Freeze drying process, the materials will be frozen to - 18°c, then move into the vacuum drying hydration, automatic control system will set the vacuum and heating temperature 

according to the freeze dryingcirve of each products to maintain thed water vapor will be co proper circumstances for FD processing. The materials stay in frozen status during the drying processtank for de anndensed on the surface of cold trap coils to absort the water out from the materials.( food freeze drying machine )
