Vacuum freeze drying technology is the most advanced technology for
food dehydration processing at present. Compared with the common
drying method, the freeze-dried food produced with this technology
features long period of quality assurance, good re-hydration
nature, good-looking color, good flavor, taste, shape and high
content of nutritious components. The dried food basically remains
unchanged in its volume and shape, it looks like sponge and has no
shrinking. This kind drying technology can be widely used in
process of vegetables, fruits, condiments, aquatic products,
biological products, medicine, beverage and etc.
Working principle
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
tank for dehydration, automatic control system will set the vacuum
and heating temperature according to the freeze drying cirve of
each products to maintain the proper circumstances for FD
processing. The materials stay in frozen status during the drying
process and water vapor will be condensed on the surface of cold
trap coils to absort the water out from the materials.
Application
The vacuum freezing and drying machine can be widely used in
various fields, such as vegetables, fruits, condiments, seafood,
biological products, medicine, beverage, specimen, etc.
