【摘要】 为了研究不同再造烟叶的物理特性及其对切丝质量与卷制质量的影响,对国内不同产地再造烟叶进行物理特性的测定及单独切丝、卷制试验研究。结果表明:①再造烟叶厚度、形状及面积大小、抗张强度、剪切力对切丝质量有明显影响,适当的再造烟叶厚度(≤0.11 mm)、形状及大小(长度55 mm左右,宽度40 mm左右)及抗张强度(≤0.54 kN/m)、剪切力(横向<17 N,纵向<29 N)有利于切丝机进行切丝;②再造烟叶外形尺寸对于卷制质量影响较大,再造烟叶尺寸过大时(长度大于65 mm,宽度大于50 mm),不利于卷制质量及其稳定性。随着再造烟叶在卷烟配方中比例的提升及单独切丝的需要,建议再造烟叶生产过程适当减少加纤量,控制片形尺寸,以提高再造烟叶切丝质量,同时开发适宜于较大抗张强度的再造烟叶切丝机。更多还原

【Abstract】 In order to study the physical characteristics of reconstituted tobacco and their influences on tobacco cutting and cigarette making, the physical characteristics of different reconstituted tobacco were determined, the tested tobacco was cut and made into cigarettes separately. The results showed that: 1)The physical characteristics(thickness, size, tensile strength and shearing force)obviously affected cutting quality, the appropriate physical characteristics were thickness ≤0.11 mm, about 55 mm × 40 mm in size, tensile strength ≤ 0.54 kN/m, and shearing force <17 N in transversal direction and <29 N in longitudinal direction. 2)The major factor affecting cigarette making was the size of reconstituted tobacco, cigarette making quality and stability deteriorated when the size was larger than 65 mm in length and 50 mm in width. In the case that reconstituted tobacco was separately cut, it was recommended to properly reduce fiber addition and control the size of finished strips within a preferable range during reconstituted tobacco production. Moreover, it was also necessary to develop a cutter adapting to the reconstituted tobacco with higher tensile strength.更多还原
