ABSTRACT
This paper was aimed to study the moisture adsorption of Chinese herbal medicine ingredients at different environment.The film mass transfer model and Fick's second law were applied to evaluate the moisture diffusion for Chinese herbal medicine ingredients.The results showed that under the temperature of 25℃ and 50％ relative humidity,the diffusion coefficient of 13 medicine ingredients reached the highest.The diffusivity was controlled by film mass transfer.However,both film mass transfer and Fick's second law can be existed at the same time under different temperature and humidity.It was concluded that the diffusion of water in the traditional Chinese medicine might have been driven by a variety of diffusion mechanism,which was obviously affected by environmental factors.
