Abstract:The influence of the temperature of the radiation heater, pressure in the chamber and sample mass on the drying characteristics of vacuum far-infrared radiation drying on honeysuckle was studied by using a self-transformed dryer. By means of linearization of moisture ratio curves, the kinetics model equation was determined as MR=exp(-Ktn). Quadratic orthogonal regression was employed to fit the relationship between modeling coefficients (n and K) and drying parameters. The results showed that the calculated values of mathematical model were quite suitable for the experimental data, and the model could illustrate moisture ratio changing regulation of vacuum far-infrared radiation drying on honeysuckle very well.
