Description

一种烟丝分类装置及工艺 A shredded tobacco sorting device and process

技术领域 technical field

本发明属于对烟丝进行在线分类技术领域,具体涉及一种烟丝分类装置及工艺。 The invention belongs to the technical field of on-line sorting shredded tobacco, and in particular relates to a shredded tobacco sorting device and process.

背景技术 Background technique

随着卷烟加工技术和工艺理念的持续创新和发展,卷烟加工正在全面进入精细化加工阶段。其中分组加工、柔性加工和产品均质化是实施精细化加工的难点和技术开发热点。从目前的发展现状看,根据烟叶原料不同产地、等级加工特点分别采取不同加工方式和加工参数的原料模块化加工技术已经较为成熟,为提升原料使用价值,拓宽原料使用范围奠定了重要基础。但是从精细化加工的关键评价标准产品质量均质化水平来看,还有一些问题需要解决,主要是批内批间烟丝各组分掺配均匀性和加香加料的均匀性还有待进一步提升,其关键影响因素在于烟丝长度的均匀性。 With the continuous innovation and development of cigarette processing technology and process concepts, cigarette processing is entering the stage of refined processing in an all-round way. Among them, group processing, flexible processing and product homogenization are the difficulties in the implementation of fine processing and the hot spots of technology development. Judging from the current development status, the raw material modular processing technology that adopts different processing methods and processing parameters according to different origins and grades of tobacco leaf raw materials is relatively mature, which has laid an important foundation for improving the use value of raw materials and broadening the scope of raw materials. However, judging from the level of product quality homogeneity, which is a key evaluation standard for refined processing, there are still some problems to be solved, mainly the uniformity of blending of each component of shredded tobacco within a batch and the uniformity of flavoring and adding materials that need to be further improved , the key influencing factor is the uniformity of tobacco length.

现有的研究表明叶丝结构分布的最佳长度应为2.00~4. 75 mm(不同配方产品略有差异),但是实际生产中叶丝长度分布极不均匀,检测数据表明>10mm的叶丝比例占40%左右,最长叶丝能达到的100mm以上,这些过长叶丝在加工过程中易互相纠缠卷曲、交织在一起形成结辫或结团烟丝,不易与为其他烟丝混合均匀,且在卷制过程中排列方式的波动性也较大。不但影响卷制物理质量的稳定性,而且直接影响不同组分烟丝、不同模块烟丝实际掺配的均匀一致性,进而影响加香加料均匀一致性。对消费者来说即为每一支卷烟吸食质量的稳定性和一致性存在差异。因此需要对叶丝结构进行优化调控,消除过长叶丝,降低长丝率,从而获得长度均匀性较好的叶丝。但是烟丝过短也有不利影响,首先烟丝过短影响烟丝的填充性能,其次短丝率过高会使卷烟空头率增加,端部落丝量变差,从而增加残次品,影响卷烟消耗。 Existing studies have shown that the optimal length of shredded leaf structure distribution should be 2.00-4.75 mm (different formula products have slight differences), but the length distribution of shredded leaf is extremely uneven in actual production, and the test data show that the proportion of shredded leaf > 10mm Accounting for about 40%, the longest shredded leaves can reach more than 100mm. These over-long shredded shreds are easy to entangle and curl each other during processing, and intertwined to form braids or agglomerated shredded tobacco, which is not easy to mix evenly with other shredded tobacco. The fluctuation of the arrangement during the rolling process is also relatively large. It not only affects the stability of the physical quality of rolling, but also directly affects the uniformity of the actual blending of different components of shredded tobacco and different modules of shredded tobacco, which in turn affects the uniformity of flavoring and feeding. For consumers, there are differences in the stability and consistency of the smoking quality of each cigarette. Therefore, it is necessary to optimize and regulate the structure of leaf silk, eliminate excessively long leaf silk, reduce the filament rate, and obtain leaf silk with better length uniformity. However, too short shredded tobacco also has adverse effects. Firstly, too short shredded tobacco affects the filling performance of shredded tobacco. Secondly, if the shredded tobacco ratio is too high, the short-cut ratio of cigarettes will increase, and the amount of shredded shreds at the end will deteriorate, thereby increasing defective products and affecting cigarette consumption.
