Application

FDG series vacuum freeze dryers are suitable for fruit, vegetable, aquatic, meat, instant foodstuff,condiments, medicine,beverage, speciman and etc.

Working principle

After some pretreatments, foodstuff 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
