目的 :研究制备中草药超细微粉的新型装置及工艺。方法 :对Trost型气流粉碎机作改进 ,借助特制的四通连续将进料与经圆盘分级出的粗料均分成二股 ,混合为高速二相流逆向对撞 ,产生极强的粉碎力 ,制备超细微粉。结果 :成功制备了 10～ 15 μm人参、胖大海、罗汉果、苦瓜等的超细微粉。 结论

Objective: To study the new device and technology in prepartion of superfined Chinese herbal medicine powders. Methods: Improving the Trost jet mill was to divide continually the feed and the coarse grains classified from a circular disc into two two phase flow by means of a especial four way pipe in mixing. and to impact with high speed oppositely each other, the superfined powders are prepared. Results: The superfined powders of ginseng, boat fruited sterculia seed and balsam pear are successfully prepared to guarantee 10～15μm in diameter. Conclusions: It is very effective to pulverize Chinese herbal medicine with this device in mass production.
