Product Use

Main Principle

After starting up, put the materials into the material box for the freezing process of the frozen materials. On the one hand, the vacuum system performs vacuuming to remove some of the moisture; On the other hand, when the material is frozen, the moisture contained in certain molecules is discharged onto the surface of the material to freeze. After meeting the freezing requirements, the material is heated and dried by the heating system, and the moisture contained in the material is brought to the freezing capture box for freezing by vacuuming, achieving the freeze-drying requirements of the material.
