为准确预测烟丝在滚筒干燥中的停留时间,采用单因素实验的方法,利用装有12块抄板的冷态滚筒设备分别研究了滚筒转速、筒内气速、烟丝流量、滚筒倾角和烟丝含水率对停留时间的影响,建立了两种新的烟丝停留时间预测模型,并将该模型与其他3种经验预测模型进行了验证对比.结果表明:①5种试验因素对停留时间均有影响.其中,滚筒转速与停留时间为指数关系,筒内气速、烟丝含水率与停留时间均为线性关系,烟丝流量与停留时间可视为线性或倒数关系,滚筒倾角与停留时间为倒数关系.②所建新模型预测结果与试验结果一致性较高,更适用于试验用冷态滚筒设备.

In order to predict the residence time of cut tobacco in a cylinder dryer accurately, the effects of cylinder's rotational speed, air velocity in cylinder, cut tobacco throughput, cylinder's inclination angle and moisture content in cut tobacco on the residence time of cut tobacco in a cold-state cylinder dryer equipped with 12 shoveling plates were studied by single factor experiments. Two prediction models were developed and compared with three other empirical prediction models. The results showed that: 1)All of the five experimental factors influenced the residence time of cut tobacco, among them, the influence of cylinder's rotational speed was exponential, that of air velocity in cylinder and moisture content in cut tobacco was linear, that of cut tobacco throughput could be regarded as either linear or reciprocal, and that of cylinder's inclination angle was reciprocal. 2) The predicted results by the developed models well agreed with experiment results, the models were more suitable for experimental cold-state cylinders.
