    摘要:

    利用改裝的干燥設備，考察了輻射板溫度、干燥室壓力和物料量對金銀花真空遠紅外輻射干燥的影響。通過水分比曲線的線性化，確定了動力學模型方程為MR=exp(-Ktn)。采用二次回歸正交試驗設計，擬合了模型參數(shù)n、K與各干燥參數(shù)的關系式。結果表明，該模型的理論值和實測值吻合良好，能夠很好地表達和預測金銀花真空遠紅外輻射干燥的水分比變化規(guī)律。

    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.
