为明确太阳能辅助热源密集烤房烘烤过程中烟叶的烘烤特性及其与普通密集烤房的差别,采用挂式重力传感器对太阳能辅助热源密集烤房和普通密集烤房烘烤过程中样本烟叶的重量进行实时测定,并通过Origin软件对太阳能辅助热源密集烤房的实验数据进行拟合得到烟叶的含水量变化曲线的模型。结果表明:太阳能辅助热源密集烤房和普通密集烤房烘烤过程中烟叶含水率变化特性基本一致;烘烤前期的部分时间段太阳能辅助热源密集烤房的失水率低于普通密集烤房;太阳能辅助热源密集烤房烘烤烟叶质量与普通密集烤房所烤烟叶质量相当且每烘烤1 kg干烟可以节约标煤0.42 kg;三次多项式模型比Logistic模型和Page模型更适合模拟太阳能辅助热源密集烤房烘烤过程中烟叶的含水率变化过程。
In order to clarify the baking characteristics of tobacco leaf and the difference with ordinary intensive curing barn in baking process of solar assisted heat source intensive curing barn, the hanging tobacco gravity sensor was used to sample the tobacco during the baking process of solar assisted heat source intensive barn and common intensive barn The real-time determination of the weight of the tobacco leaves was carried out. The software of Origin was used to fit the experimental data of solar assisted heat source intensive curing barn to obtain the model of the water content curve of tobacco leaves. The results showed that the variation of moisture content of tobacco leaves during the baking process of solar assisted heat source intensive barns and ordinary dense barns was basically the same; the water loss rate of solar assisted heat source intensive barns was lower than that of common dense barns during the pre-baking period; The quality of baked tobacco leaves in solar assisted heat source intensive curing barn was similar to that of the tobacco in normal dense barns and 0.42 kg of standard coal per 1 kg of dry smoke was saved. The cubic polynomial model was more suitable than the Logistic model and Page model for simulating solar assisted heat source Intensive barn baking process of tobacco leaf moisture content change process.
