Fruit, vegetable, aquatic, meat, instant foodstuff, chemical stoneware ect.

Working principle of lab-use freeze dryer

After some pretreatments, put the 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
