Application
Fruits and vegetables vacuum freeze drying machine is suitable for fruit, vegetable, aquatic, meat, instant foodstuff, chemical stoneware etc.
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
pretreatment system→frozen(controled by refrigeration system)→vacuum drying(controled by heating&vacuum system)→packing
