freeze dryer

Specifications

Vacuum freeze dehydrator,Working principle,

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.

Applicable range,

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

The whole equipment includes the following devices,

1.    pretreatment system

2.    freezing and drying tank

3.    heating system

4.    vacuum system

5.    refrigeration system

6.    material conveyor

7.    control system

main features:

1. water-sealed pump unit works at the initial stage( energy saving, prevents the oil pump from    being emulsified and deteriorated by the vapor);

2. three-way regulating valve adopted to automatically adjust the heat supply of water circulation system and precisely control the temperature of the heating plate;

3. the water catching cold traps adopts the unique ammonia single-base cycle refrigeration, which has good stability of liquid supply and easy operation.

4. Freon refrigeration system adopted for small and mdedium-sized equipment.
