Biological Products Freeze Dryer

The freeze-drying curve of the freeze-drying machine is the curve relationship between the plate temperature and time of the freeze-drying box. Generally, the temperature is the ordinate and the time is the abscissa. It reflects the changes of the plate temperature at different times in the freeze-drying process.

Different time has different requirements for residual moisture, different storage time, different requirements for residual moisture, and different freeze-drying time. In addition, the amount of loading, the variety of sealer, the performance of freeze-drying machine and other factors are directly related to the formulation of freeze-drying curve. Users should set the freeze-drying curve according to the nature of freeze-drying products and referring to previous freeze-drying experience, In order to obtain high-quality freeze-dried products.

The products produced by biological products freeze dryer need to have certain physical form, uniform color, qualified residual moisture content, good solubility, efficient survival rate and long storage life. Therefore, it is not only necessary to control the manufacturing process and sealed storage after freeze-drying, but also more important to comprehensively control all parameters at each stage of freeze-drying process, In order to obtain high-quality products, freeze-drying curve is the basic basis for freeze-drying process control. Therefore, some sample materials with high value and high requirements for temperature control need to select appropriate freeze dryer with freeze-drying curve, data process and high temperature control precision

Advantages of freeze drying of biological products:

1. Repack before freezing, and the dose is accurate.

2. Drying at low temperature can keep the heat sensitive substances in the dried drugs.

3. When dried under low pressure, the dried drugs are not easy to oxidize and deteriorate, and can sterilize or inhibit the activity of some bacteria due to hypoxia.

4. When frozen, the dried medicine can form a "skeleton", which can maintain its original shape and form a porous structure after drying, and the color is basically unchanged.

5. Good rehydration, lyophilized drugs can quickly absorb water and restore to the state before lyophilization.

6. Complete dehydration, suitable for long-distance transportation and long-term storage.
