Traditional Chinese medicinal materials require higher storage and transportation conditions due to their precious medical value. Among the currently known drying methods, vacuum freeze-drying technology can remove moisture from materials while maintaining their physical, chemical, and biological properties unchanged, with no loss of original components and strong rehydration properties. Freeze dried medicinal herbs have higher value and are now widely used in the industry.

The academic community has now widely applied vacuum freeze-drying technology in traditional Chinese medicine research. Beijing University of Traditional Chinese Medicine, a century old prestigious university, is a "powerhouse" in the field of traditional Chinese medicine. With strong capabilities, it has made significant contributions to the academic research and development of traditional Chinese medicine in China. To expand the research methods of traditional Chinese medicine and deepen the study of Chinese medicinal materials, Beijing University of Traditional Chinese Medicine has purchased an LGJ-S50 vacuum freeze dryer from Beijing Sihuan Qihang.

LGJ-S50 Vacuum Freeze Drying Machine

The standard cold trap temperature of LGJ-S50 vacuum freeze dryer can reach -80 ℃, and the maximum cold trap temperature can reach -83 ℃. The freeze-drying area is 0.69 square meters, and the bulk material can hold 15L with a maximum water capture capacity of 15kg. It has dual machine cascade refrigeration technology, using imported fully enclosed compressor units and international standard green and environmentally friendly refrigerants, with fast refrigeration, low cold trap temperature, and strong water capture capacity.

The design of the freeze-drying chamber complies with biopharmaceutical standards, and the freeze-drying chamber and condenser are designed separately to ensure pressure and temperature balance inside the freeze-drying chamber, achieving pharmaceutical grade pilot machine standards while improving water capture efficiency and capacity.

The control system is stable and reliable, using a PLC programmable logic control system and a 10 inch color touch screen. The operating system is more stable and reliable, and can achieve remote control on both mobile and PC ends, with three-level permissions. Real time display and recording of vacuum degree, cold trap temperature, material temperature, shelf temperature, and formation of freeze-drying curves. Freeze drying curves and tables can be exported in batches. The freeze-drying process is automatically controlled by a programmable program, with real-time switching between semi-automatic and fully automatic control. The entire freeze-drying process can be parameter modified for easy process adjustment.

The overall model is beautiful and elegant, with stable performance and powerful system, making it a good helper for scientific research experiments. Freeze dryer, choose Beijing Fourth Ring Road to set sail, good reputation, trustworthy!
