热风微波耦合干燥牛蒡动力学模型研究

热风微波耦合干燥可以很好地保护干后物料的品质，并且减少物料的干燥时间。利用Newton、Henderson and Pabis、Lagarithmic、Page、Wang and Singh等5种干燥模型方程，对热风微波耦合干燥过程中牛蒡含水率随时间的动态变化进行模拟，并通过试验对各模拟结果进行验证。结果表明，Lagarithmic方程模拟的结果与实际含水率变化较为接近。

Study on dynamic model of coupled hot air and microwave drying of burdock

With microwave hot air combined drying， high product quality and short drying period can be achieved. In the present study， 5 kinetic models based on Newton， Henderson and Pabis， Lagarithmic， Page， Wang and Singh equations， respectively， were built with the drying curves of burdock. Experiments were carried out to verify the effect of the built models. It was shown that the model based on Lagarithmic equation was the most suitable one for predicting the dynamic of the moisture content during microwave hot air combined drying.
