Vacuum Freeze Dryer is an advanced Hi-Tech dehydration technology,
It makes hydrous materials frozen in the low temperature status,
then under the vacuum condition, it adopts thermal radiation method
for heating, to sublimate ice to gas directly. After the moisture
comes out, it uses ice-condenser (cold trap) and vacuum device to
dehydrate the water content. It is a combined application
technology based on multidisciplinary development, including
refrigeration, heating, vacuum, biological, electrical and etc.
Vacuum freeze drying technology has widely application, such as for
chemical products, biologics, health product, herbs, agricultural
products ( meat, poulty, egg, sea food, vegetables and fruits and
1) Suitable for food lyophilization processing in the area of
vegetables and fruits, dietary supplements, instant food,
condiments, biological product, medicine, beverage and etc.
2) Lyophilization is a dehydration method that to sublime the
material containing water from frozen solid state to steam state
directly under the vacuum and low temperature condition.
3) It's the most advanced dehydration technic in the world
currently with the advantages of long period quality assurance,
good-rehydration, good condition of the looking, flavor, taste and
high content nutritious remains. The finished product has basically
unchanged volume and shape with spongy appearance.
4) Easy storage and transportation.
5) High automatic control with time and temperature adjustable
6) Adopt the water-sealed pump and oil-sealed pump vacuum system,
closed circulation heating system, postposition and bottom-position
cold trap to make sure the efficient operation with equal quality.
7) Extraordinary freezing efficiency is guaranteed by the extremely
efficient evaporator, optimized design and quality finishing.
