Current situation of drying methods for Chinese materia medica extract and analysis on existential problem / 中草药

The Chinese materia medica extract (CMME) is an important intermediate for the CMM preparation, and the drying process is a key link in the pharmaceutical process of CMM and has a direct impact on the quality of the drug. The development of new drying technology is the key point of the industry technology transformation and upgrading about traditional Chinese medicine manufacturing, and plays an important role in the process of modernization of CMM. In this paper through the literature research statistical analysis, the current research situation of the CMME common drying methods were reviewed, the characteristics and adapt scope of commonly used extract drying technology were analyzed and summarized, some of the problems which exist in the promotion of the CMME drying technology were discussed and the corresponding countermeasures were put forward. Then, the suitable drying technology for different CMMEs were summarized. Finally, the paper illustrates the drying CMME development trend in China. This paper provides a useful reference for the research and development applied to medicine extract efficient drying techniques, and provides new ideas for the optimization and upgrading of related equipment.

Status and problem analysis of drying process and equipment for traditional Chinese medicinal materials and preparations / 中国中药杂志

Drying is the critical link during pharmaceutical process of traditional Chinese medicine (TCM), which is directly related to the quality of drugs. The key to technology upgrading of pharmaceutical equipment in Chinese materia medica enterprise is the development of new drying techniques, which concerns the modernization of TCM. The study provides new ideas for the drying technology and equipment by means of reviewing the research status of drying process for the traditional Chinese medicinal materials and preparations, and analyzing the traditional and modern drying methods and equipment, as well as their existing problems and corresponding measures for the drying processes and equipment. In addition, this paper expounds the development trend of traditional Chinese medicinal materials and preparations of drying process and equipment.
