目的：建立中药材干燥数学模型，为优化干燥工艺提供理论依据。方法：运用传热学原理，探求中药材干燥过程中影响因数及能量变化过程，建立中药材干燥数学模型，并对参数进行分析。结果：现有中药材的干燥研究多为经验知识的总结，在干燥方法、工艺及设备的选择上存在很大的盲目性。本文量化了中药材干燥过程，建立起中药材干燥数学模型，建立起干燥条件参数：热传导参数C、热辐射参数D、为热交换参数E，用于评价干燥设备的干燥性能；建立起干燥物性参数：孔隙率Ф、比热Cp、药材表面积S等，用于评价药材可干燥能力。结论：加强中药材干燥基础理论的研究，为选择合理的干燥方法、设备及工艺参数，提高干燥效率，降低能耗提供了新的方法和思路。

This study was aimed to establish the drying mathematical model of Chinese herbal medicine. The energy changes and influence factors were studied in the process of Chinese herbal medicine dried by thermodynamic theory. The Chinese herbal medicine drying mathematical model and analysis of the parameters ere established. The results showed that the existing drying research of Chinese herbal medicine is the summary of experienced knowledge. There is a big blindness in the choice of the drying method, process and equipment. We quantized the process of drying, and established Chinese herbal medicine drying mathematical model. The established parameters of the external environment are the heat conduction parameter C, the thermal radiation parameter D, and heat exchange parameters E. These parameters reflect the drying efficiency of the drying equipment. The established parameters of medicinal properties are the porosity Ф, specific heat Cp, herbs surface area S. These parameters reflect the herb drying capacity. It was concluded that the strengthening of basic theory study on Chinese herbal medicine drying will provide new methods and ideas for the reasonable selection of drying methods, processes and equipments. Therefore, the drying efficiency will be improved and the energy consumption will be reduced.
