应用热力学基本理论,建立中药饮片水分吸附与解吸附过程中的热力学参数及相关方程,分析中药饮片的水分吸附与解吸附特性。探讨微分吸附焓、微分吸附熵、积分吸附焓、积分吸附熵和吸附结合自由能等热力学参数的物理意义,为中药饮片的水分吸附与解吸附机制、最佳干燥工艺参数、贮存条件、包装方法等方面研究提供理论依据。
Based on the basic theory of thermodynamics, the thermodynamic parameters and related equations in the process of water absorption and desorption of Chinese Herbal Medicine Pieces were established, and the characteristics of adsorption and desorption of Chinese Herbal Medicine Pieces were analyzed. The physical meaning of differential adsorption enthalpies, differential adsorption entropies, integral enthalpies of adsorption, integral adsorption entropies and free energy of adsorption and adsorption are discussed in this paper. The mechanism of adsorption and desorption of water for Chinese Herbal Medicine Pieces, the optimum drying process parameters, storage conditions, packaging methods And other aspects of research to provide a theoretical basis.
