 Pharmaceutical Freeze Dryer Machine

Advantages of vacuum freeze-drying of pharmaceutical freeze dryer machine: The working principle of the pharmaceutical freeze dryer is to use the sublimation principle in a high vacuum state so that the moisture in the pre-frozen material is directly sublimated into water vapor in the ice state without melting ice. be removed for freeze-drying purposes.

Pharmaceutical freeze dryers are suitable for heat-sensitive substances. Because freeze-drying is performed at low temperatures, it is particularly suitable for many heat-sensitive substances without denaturation or loss of biological activity. Therefore, it has been widely used in the pharmaceutical industry. The advantages of vacuum freeze-drying of pharmaceutical freeze dryer are mainly as follows:

1. The material loss is small. When drying at low temperature, the loss of some volatile components in the substance is very small, which is suitable for drying some chemical products, medicines, and food.

2. Maintain the shape of the material. During the freeze-drying process, the growth of microorganisms and the action of enzymes cannot be carried out, the volume is almost unchanged, the original structure is maintained, no concentration phenomenon occurs, and there is very little oxygen. Therefore, the freeze-drying machine can maintain the original properties, will not oxidize, and will not change the material structure.

3. The substance is easy to dissolve. The dried substance is loose and porous, in the form of a sponge, dissolves rapidly and completely after adding water, and returns to its original shape almost immediately.

4. Substances can be stored for a long time. Drying can remove more than 95-99% of the moisture so that the dried product can be stored for a long time without deterioration. Therefore, freeze-drying is currently widely used in the pharmaceutical industry, food industry, scientific research, and other departments.
