| 摘 要： | 本文研究了片状中药材淮山的微波干燥规律,并根据微波辐射干燥的质量扩散和热传导原理,建立了微波辐射干燥片状中药材淮山的数学模型.试验了用不同能量的微波辐射不同厚度的片状淮山样品在干燥过程中样品的温度、水分和体积变化等物理特性变化及干燥效果,并与数学模拟曲线进行对照.结果表明,试验结果与模拟计算结果基本吻合,所建立的中药材微波干燥数学模型可成功解释其微波干燥行为.

| Abstract: | A new mathematical model, aimed at investigating the behaviors of microwave drying of traditional chinese medicine was established. It based on mass-energy. eonsersvation law. Dioscorea opposita Thunb. was used as sample and its drying efficiency have been developed at different levels of microwave power and sample thickness. The results shown that the levels of them have a strong influence on drying process. The experimental values were approximately in accord with the calculated values by mathematical model. It explained successfully the behaviors of microwave drying of Diosorea opposita Thunb. slices. . |
