技术领域 technical field

背景技术 Background technique

辊压法再造烟叶以其设备简单、能耗低、成本低，被国内大多数卷烟企业所采用，但其生产的再造烟丝因抗张强度小、耐水性差、填充性能低而使有效利用率低，影响了卷烟配方的吻合性和产品质量稳定性；同时，辊压法再造烟叶掺配比例的稳定性和配方比例的符合性也是评价卷烟生产工艺工序能力的重要指标。目前通常的做法有三种：人工挑选法、单耗比值法、填充比值法，这些方法具有工作量大、结果准确性差等缺点，且无法判断烟丝内各组分在微小单元内是否也符合设计的配方，更无法判定烟丝在立体空间内是否分布均匀。因此，建立准确测定卷烟烟丝中辊压法再造烟叶掺配比例及其转化利用率有非常重要的意义。 Roller-pressed reconstituted tobacco is adopted by most domestic cigarette companies due to its simple equipment, low energy consumption and low cost. , affecting the conformity of the cigarette formula and product quality stability; at the same time, the stability of the blending ratio of the reconstituted tobacco leaves by the rolling method and the conformity of the formula ratio are also important indicators for evaluating the capability of the cigarette production process. At present, there are three common methods: manual selection method, unit consumption ratio method, and filling ratio method. These methods have the disadvantages of heavy workload and poor accuracy of results, and it is impossible to judge whether each component in shredded tobacco meets the design requirements in the tiny unit. formula, and it is impossible to determine whether the shredded tobacco is evenly distributed in the three-dimensional space. Therefore, it is of great significance to establish an accurate determination of the blending ratio and conversion utilization rate of reconstituted tobacco leaves by rolling method in shredded cigarette tobacco.
