The entire freeze-drying process of the Shanghai Yetuo pilot freeze-drying machine is carried out in a low-temperature and low-pressure environment, and the freeze-drying method can effectively preserve the thermosensitive components and original biological characteristics of the freeze-dried product. The freeze-drying process is a gradual and slow heating process from low temperature. If the heating is too fast or too high, it can easily lead to the collapse of the appearance and poor appearance of the freeze-dried product. The freeze-drying process is divided into three stages: pre freezing, sublimation drying, and analytical drying.

The Shanghai Yetuo pilot freeze-drying machine has strong refrigeration capacity, meets temperature control requirements and water capture capacity requirements. Has strong vacuum capability, meets requirements and vacuum control requirements. The stable operation of the circulatory system meets the requirements of uniform temperature. The electronic control system is fully functional, meeting the requirements of accurate, stable, safe operation control, and data recording, preservation, and traceability.

Freeze drying is the process of pre cooling and freezing substances containing a large amount of moisture into solids, and then directly sublimating water vapor under vacuum conditions, leaving the substance itself in the frozen ice shelf. Therefore, after drying, its loose and porous volume remains unchanged.

Causing a decrease in the temperature of the product itself and slowing down the sublimation rate, in order to increase the sublimation rate and shorten the drying time, the product needs to be heated appropriately. The entire drying process is carried out at a lower temperature.

Due to the preservation of the original characteristics and mechanisms of substances after freeze-drying, such as color and shape, they remain basically unchanged and can be stored for a long time at room temperature. Therefore, freeze-drying machines are widely used in drying processes such as pharmaceutical freeze-drying, food freeze-drying, biological product freeze-drying, microbial freeze-drying, industrial material freeze-drying, and cultural freeze-drying. Choosing a good freeze-drying machine has an impact on the effectiveness of substance freeze-drying, whether the substance freeze-drying is successful, and the importance of meeting freeze-drying requirements.

The Shanghai Yetuo freeze-drying machine has the advantages of meeting the freeze-drying process, stable operation, low failure rate, and long service life. Choosing a good and fully functional vacuum freeze dryer is important for ensuring the requirements of material freeze-drying and long-term stable operation.
