| 摘 要： | 目的研究中药材低温超微粉碎的粉碎机理。方法采用低温超微振动粉碎机组,对中药甘草进行常温和低温下的超微粉碎;采用激光粒度仪、扫描电镜等对粉体特征进行表征。结果与常温粉碎相比,低温粉碎不仅能在更短的时间内得到超微粉体,而且粉末粒径分布更窄,休止角更小,从而流动性得到较大改善。结论振动磨可以在低温下简单、高效、超细地粉碎甘草。

| Abstract: | Objective: To discuss the mechanism of superfine comminution of traditional Chinese medicine (TCM) at low temperature. Method:Glycyrrhiya uralensis roots were at room superfinely comminuted temperature and at low temperature by cryogenic vibration mill;The superfine powders were observed and analyzed by laser particle size analyzer and SEM. Result: The powder processed at low temperature was of smaller effective diameter and narrower size distribution and was also with smoother surface and smaller angle of repose. Conclusion: The G. uralensis roots could be superfinely comminuted with high efficiency and simple procedure by vibration mill at low temperature. |
