Bird's Nest Vacuum Freeze Dryer Yogurt Cube Soup Congee Lyohilizer
Vacuum Freeze Dryer
Working principle
After some pretreatments, in a low temperature and vacuum
surroundings, the inner moisture of the foodstuff will sublimate
from solid state to gaseous state so that the foodstuff is dried.
The whole processing line including the following parts
1. pretreatment system
2. freezing and drying tank
3. heating system
4. vacuum system
5. refrigeration system
6. material conveyor
7. control system

Product Description
The vacuum freezing and drying technology is currently the most
advanced dehydrating processing technology in the world. Compared
with the commonly used drying method, the freezedried food produced
by lyophilizer features long period of quality assurance, good
re-hydration nature, good-looking color, good flavor, taste and
high content of nutritious components the dried food basically
remains unchanged in its volume and shape,looks like sponge and has
no shrinking.
Brief introduction
FDG series lyophilizers are consisted of food pre-freezing system,
freezing and drying pot, heating system, vacuum system,
refrigerating system, material conveying system and control system,
etc.
The vacuum system adopts the combination of water-sealed pump and
oil-sealed pump. The way of heating is closed water circulation
heating. And the condenser is placed inside heating tank besides
the heating plates. Of course, it can be customized according to
the practical condition, for example, placed above the drying pot.
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.
