摘　　要：目的:研究滚动床结构对其内部颗粒传热特性,探讨其对中药炮制过程的影响。方法:以径向截面多点测温法对滚筒内物料温度进行实时监测,优化滚筒结构;以水红花子爆花率及槲皮素的含量为评价指标,采用HPLC法进行含量测定。结果:滚动床最佳结构条件为转速为rpm=50,内置8个135°"L"型挡板,此时其内物料颗粒传热最为均匀,且此条件机械化炮制水红花子爆花率达50%以上,槲皮素含量为0.69mg.g-1,明显高于传统方法炒制的水红花子槲皮素的含量。结论:滚动式炒制机内物料设计合理,传热迅速、均匀、使用方便,能够保障和提高中药炮制品的质量,此研究对药材炒制机械化生产提供科学依据。objective ： Research on rolling bed structure on its internal particles heat transfer characteristics, and discussing the in fluence on processing for TCM. methods： Roller structure was optimized by monitoring materials temperature in roller with radial section of multi-point temperature measurement method ; With fructus Polygoni Orientalis frizzling rate and its internal quercetin content as evaluation indexes ; HPLC method for content determination, results ： Optimal structure of the rolling bed as following： stir frying speed 50 r ~ rain - 1 , 8 flights with L-shaped, and then the oPtimization of mechanization processing fructus Polygoni Orientalis has a high frizzling rate above the 50%, and the content of the quercetin is 0. 69mg · g^-1, this method is better than the traditional processing. conclusion： The rolling bed had a optimal structure, heat transfer quickly and evenly, it can be improved a quality of processing TCM. This research can provide a experimental basis for mechanized frying production of Chinese material medicine.
