摘　　要：为完善叶丝加料工艺技术,探索叶丝加料效果的影响因素,采用正交试验,考察了物料流量、滚筒转速、加料助喷压力、热风温度等参数对叶丝加料效果的影响,采用偏最小二乘法建立了试验参数与加料效果的回归模型。结果表明物料流量、助喷压力对叶丝加料效果有显著影响,各参数对料液有效利用率的影响大小为:物料流量>助喷压力>滚筒转速>热风温度;对加料均匀性的影响大小为:助喷压力>物料流量>滚筒转速>热风温度。建立的回归模型对料液有效利用率和料液含量变异系数有较好的预测效果,偏差分别为0.7%,0.5%。In order to improve the technology of cut strip casing, the factors influencing the casing effects of cut strips were examined by an orthogonal experiment in terms of tobacco throughput, cylinder rotating speed, nozzle pressure and hot air temperature, meantime, the regression models between the tested parameters and the casing effects were established by partial least square method. The results showed that tobacco throughput and nozzle pressure significantly influenced the casing effects, the tested parameters in the order of their influences on the effective utilization rate of casing were tobacco throughput 〉 nozzle pressure 〉 cylinder rotating speed 〉hot air temperature, while in the order of their influences on casing uniformity were nozzle pressure 〉 tobacco throughput 〉 cylinder rotating speed 〉 hot air temperature. The established regression models had satisfactory prediction accuracy; the deviations between predictive and measured values of the effective utilization rate of casing and the variation coefficient of casing content in cut strips were 0.7% and 0.5%, respectively.
