Abstract[Objective] To study effects of SH9 feed moisture content on tobacco comprehensive quality after drying. [Method] The change of tobacco comprehensive quality under different feed moisture content was studied. [Result] The results showed that, different feed moisture content has significant effects on tobacco, filling value and sensory quality, while has no significant effects on whole tobacco rate and broken tobacco rate. [Conclusion] The study can provide reference basis for adopting proper control parameters in tobacco processing with SHP online expansion equipment.

SH9在线高速膨胀系统是我国自主研发的一种烟丝干燥设备,国内有较多应用[1]。在卷烟加工过程中,干燥工序对卷烟加工质量有重要影响,一般情况下干燥工序的进料含水率、工艺气流温度是SH9在线高速膨胀系统的主要参数[2-3]。该种干燥设备在干燥烟丝过程中由于系统热损失的变化,工艺气流温度变化明显,在控制过程中常常通过调整进料含水率来影响工艺气流温度。为此,笔者研究了SH9进料含水率对干燥后烟丝综合质量的影响,以期为卷烟企业在用该设备对烟草加工时选择合适的控制参数提供依据。

1材料与方法

1.1材料

长春卷烟厂生产的A牌号三类烤烟型配方烟丝,SH92在线高速膨胀系统系统(常州智思),InfraLab710实验室用红外水分仪,YDZ430智能填充值测定仪,YQ2烟丝振动分选筛。

1.2方法

在正常生产过程中,调整进料含水率,满足工艺气流温度在标准中心(190±5)℃范围内波动,其他工艺指标

控制稳定,以进料含水率为变量因素,取4个试验水平,水平1~4的进料含水率(平均值)依次为24.50%~24.3%、2410%~24.3%、23.90%~24.10%、23.70%~23.90%,以烟丝填

充值、整丝率、碎丝率为考察结果指标,评价干燥后烟丝的综合质量状况。

依据试验要求,对所选批次烟丝在贮丝时间满足工艺标准(4 h)后,在贮丝柜取样(取样时避开柜头、柜尾300 kg,剥去表层10 cm),每批次取样1 500 g。检测烟丝整丝率、碎丝率、填充值,整丝率、碎丝率检测1次,填充值检测3次取平均值,每个水平取9批次。另每个水平选1个批次按上述方法取样15 kg,制作品吸样品。

2结果与分析

2.1进料含水率对烟丝整丝率的影响每个水平9个批次烟丝的整丝率见表1。对表1中试验数据进行单因素方差分析,得每个含水率水平9个批次的烟丝整丝率平均数与标准差,Levene检验显示方差齐,F(3,32)=1.39,P=0.264,不同

2.2进料含水率对烟丝碎丝率的影响4个进料含水率水平9个批次烟丝碎丝率见表2。对表2中试验数据进行单因素方差分析,得每个含水率水平9个批次的烟丝碎丝率平均数与标准差,Levene检验显示方差不齐,事后多重比较Dunnett T3检验显示处理间差异不显著。

2.3进料含水率对烟丝填充值的影响4个进料含水率水平9個批次烟丝填充值见表3。对表3中试验数据进行单因素方差分析,得每个含水率水平9个批次的烟丝填充值平均数与标准差,Levene检验显示方差齐,F(3,32)=7.57,P=0.001,方差分析显示,不同试验水平结果差异显著。

2.4进料含水率对烟丝感官质量影响

从不同试验水平的品吸样品与标准样品三点检验结果(表4)可以看出,24.50%~24.30%进料含水率水平的品吸样品与标准对比样差异显

3结论

该试验条件下,进料含水率对烟丝加工质量有一定影响,尤其对填充值及感官质量影响显著。

SH9在線高速膨胀系统生产过程中为保证烟丝质量的稳定,应尽量保持进料含水率稳定;当工艺气流温度有大范围波动时,可小范围调整进料含水率来干预工艺气流温度,进料含水率调整范围不宜大于0.3%。
