Description
1. Freeze-drying machine applies a technical method by which moisture-bearing samples frozen in advance become dry in the vacuum owing to vaporizing away the moisture.
2. The samples frozen can be well-storage for a long time and returned to their former state once being watered without losing their original biochemical properties.
3. The freeze drying technology is especially ideal for those bio-products sensitive to antibiotic, vaccines, blood products, enzymesand hormones.
4. This machine is also suitable for sample freezing experimentsin labs and small-scale production.
5. The series can be divided into four type: Ordinary, Top-Press, Ordinary Multi-Pipeline, Top-Press Multi-Pipeline, T-Frame with Pre-Freeze Function.
Freeze drying is a process whereby water is removed from frozen materials by converting the frozen water directly into its vaper without the intermediate formation of liquid water. The basis for this sublimation process involves: The absorption of heat by the frozen sample in order to vaporize the water, the use of a vacuum pump to enhance the vapor onto a condenser; the removal of water vapor from the surface of the sample; the transfer and deposit of water vapor onto a condenser; the removal of heat, due to ice formation, from the condenser by means of a refrigeration system. In essence, the freeze dry process is a balance between the heat absorbed by the sample to vaporize the water and the heat removed from the condenser to convert the water vapor into ice.
