| Abstract: | Research on vacuum infrared radiation drying of Rehmanniae was carried out using an improved vacuum infrared radiation dryer.By means of logarithm of experimental data and linear regression,the pattern of thin-layer vacuum infrared drying model of Rehmanniae,which was related to the temperature of radiation board and pressure in the chamber,was set as Modified Page equation,and the expression and values of model parameters were also obtained subsequently.The model could describe and predict change regulatio... |
