Shanghai Yetuo freeze-drying machine is a technology that uses sublimation principle for drying. This is a process of rapidly freeze-drying substances at low temperatures, and then directly sublimating frozen water molecules into water vapor in an appropriate vacuum environment. Yonghe Innovation's pilot scale freeze-drying machine is widely used in industries such as biopharmaceuticals, pharmaceuticals, and food. For example, the production of biological products such as BCG vaccine, meningitis vaccine, measles vaccine, influenza vaccine, etc; In the production of Western medicine, antibiotics, and drugs for the circulatory system.

Advantages of using Shanghai Yetuo freeze-drying machine:

1. The heat consumption is lower than other drying methods.

2. Many thermosensitive substances do not denature or become inactive.

3. During low-temperature drying, the loss of some volatile components in the material is minimal.

4. During the freeze-drying process, the growth of microorganisms and the action of enzymes cannot be carried out, so the original properties can be maintained.

5. Due to being dried in a frozen state, its volume has hardly changed, maintaining its original structure without concentration.

6. Drying can remove over 95% to 99% of moisture while maintaining the original chemical composition and physical properties of the dried material, such as porous structure and colloidal properties.

7. Due to the fact that drying is carried out under vacuum with little oxygen, some easily oxidizable substances are protected.

8. The dried material is loose, porous, and sponge like. After adding water, it quickly and completely dissolves, almost immediately restoring its original properties.

Application areas of Shanghai Yetuo freeze dryer:

1. Preservation of biological products and drugs, such as antibiotics, antitoxins, supplies, and vaccines.

2. Biological tissues and specimens, such as skin, bones, aorta, heart valves, and other peripheral tissues, are dried and preserved for transplantation into different or homologous animals; Produce various animal and plant specimens.

3. Microorganisms and algae: Long term preservation of various bacteria, yeast, enzymes, protozoa, microalgae, etc.
