Mulberry Yellow Traditional Chinese Medicine Vacuum Freeze Drying Machine

　　Chinese herbal medicine vacuum freeze-drying machineIt is a vacuum freeze-drying machine equipment that applies freeze-drying technology to the drying and processing of traditional Chinese medicine. Its working principle is that the processed traditional Chinese medicine is pre frozen and crystallized in the freeze-drying machine, and then directly sublimated and dried in a vacuum environment of about 1-30pa to obtain a freeze-dried traditional Chinese medicine product with a water content of about 1%. The main features are the ability to preserve the original medicinal properties of traditional Chinese medicine, making it convenient to store and carry at room temperature for a long time. It has strong rehydration properties, is easy to use, is easily absorbed, and does not require further boiling or decoction. The traditional Chinese medicine freeze-drying technology of the freeze-drying machine solves the problem of inconvenient storage, carrying, and use of traditional Chinese medicine, providing high efficiency and convenience.

　　Chinese herbal medicine vacuum freeze-drying machineAfter obtaining a traditional Chinese medicine formula, the decoction is prepared by mixing and boiling, and then enters the SFD traditional Chinese medicine freeze-drying machine for low-temperature cooling to crystallize into a solid state. It is frozen at a crystallization temperature of -50 ℃ for about 3-5 hours, and then enters the first drying stage of vacuum drying. The temperature control range for the first drying is -50~10 ℃, and the vacuum control of the freeze-drying machine is 15PA ± 3. The drying time is about 12~20 hours. After one drying session, the traditional Chinese medicine freeze-drying machine enters the analytical drying stage, with a temperature control range of 15-55 ℃. The vacuum control of the vacuum freeze-drying machine is 10PA ± 3, and the freeze-drying time is about 10-15 hours. After the analysis drying is completed, the freeze-drying machine automatically enters the insulation stage. Before discharging, a pressure rise test is conducted to ensure that the freeze-drying effect is achieved. Finally, the freeze-dried material of traditional Chinese medicine with a water content of 1% is obtained, which is then crushed at low temperature to obtain the freeze-dried powder of traditional Chinese medicine decoction. The entire vacuum freeze-drying process involves physical dehydration in a low temperature and vacuum environment, effectively ensuring that the material does not mutate, oxidize, or undergo chemical reactions to ensure the pharmacological properties of traditional Chinese medicine.

After the vacuum freeze dryer, the material is put into the material box for freezing The freezing process of materials involves, on one hand, the vacuum system evacuating and removing a portion of the moisture; On the other hand, when the material is frozen, the moisture contained in the molecules is discharged to 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.

Traditional drying can cause material shrinkage and damage cells. The structure of the sample will not be damaged during the freeze-drying process, as the solid components are supported by the solid ice in their positions. When ice sublimates, it leaves pores in the remaining dry material. This preserves the integrity of the biological and chemical structure and activity of the product. In the laboratory, freeze-drying has many different uses, and it is widely used in many biochemical and pharmaceutical applications. It is used to obtain biomaterials that can be preserved for a long period of time, such as microbial culture, enzymes, blood, and drugs. In addition to the stability of long-term preservation, it also retains its inherent biological activity and structure. For this purpose, vacuum freeze-drying machines are used to prepare tissue samples for structural studies (such as electron microscopy). Freeze drying is also used in chemical analysis, which can obtain dried samples or concentrate samples to increase analysis sensitivity. Freeze drying stabilizes the composition of the sample without changing its chemical composition, making it an ideal analytical aid. Freeze drying can occur naturally. Under natural circumstances, this process is slow and unpredictable. Through freeze-drying systems, people have improved and subdivided many steps, accelerating this process.
