微波膨胀烟梗二次切丝工艺参数研究

Effects of Technical Parameters of Twice Cutting on Quality of Microwave Expanded Cut Stem

为研究微波膨胀烟梗二次切丝工艺参数对微波膨胀梗丝品质的影响,采用均匀实验设计法分析了不同切片厚度、切丝宽度组合对微波膨胀梗丝填充值、梗丝耐加工性、感官质量的影响,在此基础上建立了切丝参数组合对梗丝品质影响的回归方程,并进行了外部验证。结果表明：1整丝率、填充值与切片厚度、切丝宽度极显著正相关;碎丝率与切片厚度、切丝宽度极显著负相关;2切片厚度相同时,感官质量随切丝宽度的增加而降低;切丝宽度相同时,随切片厚度的增加,感官质量得分先增加后降低;3切片厚度范围0.75-0.85 mm、切丝宽度范围0.30-0.35 mm时,微波膨胀梗丝的综合品质最优。

In order to investigate the influences of technical parameters of twice cutting on the quality of microwave expanded cut stem, uniform experimental design was adopted to study the effects of different combinations of sliced thickness and cutting width on the filling value, processing endurance and sensory quality of microwave expanded cut stem. Based on that, a regression equation for cutting parameter combination and cut stem quality was developed and verified via external validations. The results showed that： 1） The percentage of long strands and filling value extremely significantly positively correlated, while the percentage of broken strands extremely significantly negatively correlated to sliced thickness and cutting width. 2） At the same sliced thickness, the sensory quality decreased with the increase of cutting width; at the same cutting width, the sensory quality scores increased first then decreased with the increase of sliced thickness. 3） The best integrated quality of microwave expanded cut stem achieved when sliced thickness ranged from 0.75 to 0.85 mm and cutting width from 0.30 to 0.35.
