为研究不同配方片烟的混合干燥特性，考察了河南平顶山和驻马店两个产地C2F片烟及其在2∶1、1∶1和1∶2质量配比下混合样品干燥过程的含水率变化情况；比较了5种常用的干燥模型，在此基础上建立了描述不同产地片烟混合干燥特性的数学模型。结果表明：①确立了Newton薄层干燥模型作为基础模型；②不同片烟混合干燥动力学过程的数学模型分配系数包含不同原料初始干基含水率和平衡干基含水率两个因子，理论上可以描述任意质量比混合片烟的干燥过程；③Newton模型参数拟合值和混合干燥模型参数计算值之间的相对误差小于5%。该模型可以预测不同质量比混合片烟的干燥动力学参数，评价混合后片烟干燥特性。

In order to study the drying characters of tobacco of different makeup, the changes of moisture content in C2F strips from Pingdingshan and Zhumadian, Henan, and their mixtures at the mass ratios of 2∶1, 1∶1 and 1∶2 during drying were investigated. Five conventional drying models were compared, and then a mathematical model was established to describe the drying characters of the mixtures of strips. The results showed that: 1) Newton thin layer drying model was determined as the basic model. 2) The distribution coefficient in the dynamic drying model contained two factors, initial moisture content and equilibrium moisture content of the dried strips. 3) The relative error between the fitted values of Newton model parameters and the calculated values of drying model parameters were less than 5%, the established mathematical model could predict the drying dynamic parameters of mixed strips and evaluate the drying characters of mixed strips.
