vacuum freeze dryer, 1,Long shelf life, 2,No shrinking, 3,No shape changing, 4,Good re-hydration - details see: https://www.machineto.com/fruit-freeze-dryer-10297350

Application

Vacuum freeze dryer suitable for ruit, vegetable, aquatic, meat, instant foodstuff, chemical stoneware etc. except grease.

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
