本发明属于卷烟生产技术领域，具体涉及一种提高卷烟烟灰白度的方法。The invention belongs to the technical field of cigarette production, and in particular relates to a method for improving the ash whiteness of cigarettes.
背景技术Background technique
消费者在购买卷烟时很在意烟支燃烧后烟灰的颜色，烟灰颜色发白的卷烟能够得到消费者更多的青睐，然而现在很多国产卷烟的烟灰却呈现出黑灰色。卷烟抽吸后烟灰的颜色反映了卷烟抽吸时烟丝的燃烧是否完全，烟灰颜色越白，表明烟丝燃烧越完全；而且通常情况下，卷烟燃烧越完全，卷烟香气也会更透发，满足感更强，同时卷烟的焦油释放量和CO释放量更低。而烟灰发黑的卷烟烟丝燃烧不完全，卷烟的香气不能充分地透发，吸烟者便不能得到充分的满足感，而且燃烧不完全的卷烟香气不丰满、浓度较差，同时烟丝燃烧不完全就会产生更多的有害物质，对人的身体造成更深的伤害。随着社会对吸烟和健康问题的关注，国家对卷烟产品的焦油量控制逐渐加强。现有的卷烟加工过程中，一方面为了降低卷烟焦油的释放量、降低卷烟对人体健康的危害，另一方面为了更加有效地利用烟叶原料，降低卷烟生产成本，通常会在烟叶原料中加入烟草薄片。烟草薄片是利用卷烟加工过程中废弃的烟末、烟梗、烟叶碎片等为原料，采用稠浆法或造纸法加工而成的再造烟叶。稠浆法是用烟末与胶混合形成均匀的稠浆，均匀涂布之后烘干成型得到，由于稠浆法加工的烟草薄片以烟末为原料，因此其力学性能差、填充值低，不利于烟丝的燃烧完全，对降低卷烟产品的焦油量也没有明显作用，而且其中混合的胶在卷烟抽吸时会产生很多杂气，导致卷烟杂气重，口感差；造纸法则利用烟梗和烟叶碎片为原料，将其在溶剂中充分浸泡后，分离原料中的水溶物和纤维等不溶物，所得纤维等不溶物和外加木浆纤维通过制浆、抄造成型为薄片的基体，所得水溶物的溶液浓缩后涂布到薄片基体上，最后经干燥、分切成为造纸法再造烟叶。造纸法再造烟叶力学性能好、密度小，有利于燃烧，且其焦油释放量低，与天然烟叶混配在一起加工，制成卷烟，一方面可以提高烟丝的燃烧性，使烟丝燃烧完全，提高烟灰的白度，另一方面可以降低卷烟焦油的释放量、降低卷烟对人体健康的危害，而且还可以改善卷烟的物化性能，进而提高卷烟的品质。When consumers buy cigarettes, they are very concerned about the color of the ash after burning. Cigarettes with whitish ash can be favored by consumers more. However, the ash of many domestic cigarettes is now black and gray. The color of the ash after cigarette smoking reflects whether the shredded tobacco is completely burned when the cigarette is smoked. The whiter the ash color, the more completely the shredded tobacco is burned; and usually, the more completely the cigarette is burned, the more fragrant the cigarette will be, giving you a sense of satisfaction. Stronger, with lower tar and CO emissions from cigarettes. On the other hand, the shredded tobacco of cigarettes with blackened soot is incompletely burned, and the aroma of cigarettes cannot be fully penetrated, and the smoker cannot get sufficient satisfaction. More harmful substances will be produced, causing deeper damage to the human body. As the society pays more attention to smoking and health issues, the state gradually strengthens the tar control of cigarette products. In the existing cigarette processing process, on the one hand, in order to reduce the release of cigarette tar and reduce the harm of cigarettes to human health, on the other hand, in order to more effectively use tobacco leaf raw materials and reduce cigarette production costs, tobacco is usually added to the tobacco leaf raw materials. Flakes. Tobacco sheet is a reconstituted tobacco leaf processed by thick pulp method or papermaking method by using waste tobacco powder, tobacco stems, tobacco leaf fragments, etc. during cigarette processing as raw materials. The thick slurry method is to mix tobacco powder and glue to form a uniform thick slurry, which is uniformly coated and then dried and formed. Since the tobacco sheet processed by the thick slurry method uses tobacco powder as raw material, its mechanical properties are poor and its filling value is low. It is conducive to the complete combustion of shredded tobacco, and has no obvious effect on reducing the amount of tar in cigarette products, and the glue mixed in it will generate a lot of miscellaneous gas when the cigarette is smoked, resulting in heavy miscellaneous gas and poor taste; the papermaking method uses tobacco stems and tobacco leaves Fragments are used as raw materials. After fully soaking them in the solvent, the water-soluble matter and insoluble matter such as fibers in the raw material are separated. The concentrated solution is coated on the thin sheet substrate, and finally dried and cut into papermaking reconstituted tobacco leaves. Papermaking reconstituted tobacco leaves have good mechanical properties, low density, and are conducive to combustion, and their tar release is low. They are mixed with natural tobacco leaves and processed to make cigarettes. On the one hand, they can improve the combustibility of cut tobacco, make tobacco burn completely, and improve The whiteness of soot, on the other hand, can reduce the release of cigarette tar and reduce the harm of cigarettes to human health, and can also improve the physical and chemical properties of cigarettes, thereby improving the quality of cigarettes.

通常情况下，卷烟烟灰的白度主要与烟丝的燃烧性有关，烟丝的燃烧性主要和烟叶原料的燃烧性、成品烟丝的含水率、弹性、松散性和填充值、所施加料液等有关。具体而言，烟叶原料的燃烧性与其所含化学成分及组织疏松程度有关，烟叶钾氯比越高，燃烧性越好，卷烟的感官质量也会相应提高且能够影响卷烟的焦油释放量；烟叶组织越疏松，燃烧性越好，而组织疏松的烟叶一般成熟度较高；成品烟丝的含水率越低，燃烧性越好；成品烟丝的弹性、松散性和填充值越高，燃烧性越好，所施加的料液中助燃成分越多，成品烟丝的燃烧性越好。鉴于上述原理，本发明作出了以下改进：Normally, the whiteness of cigarette ash is mainly related to the flammability of shredded tobacco, which is mainly related to the flammability of raw tobacco leaves, the moisture content, elasticity, looseness and filling value of finished shredded tobacco, and the applied liquid. Specifically, the combustibility of tobacco leaf raw materials is related to its chemical composition and tissue porosity. The higher the potassium-chloride ratio of tobacco leaves, the better the combustibility, and the sensory quality of cigarettes will be improved accordingly, which can affect the tar release of cigarettes; tobacco leaves The looser the tissue, the better the combustibility, and the looser tobacco leaves generally have higher maturity; the lower the moisture content of the finished tobacco, the better the combustibility; the higher the elasticity, looseness and filling value of the finished tobacco, the better the combustibility , the more combustion-supporting components in the applied feed liquid, the better the combustibility of finished shredded tobacco. In view of the foregoing principles, the present invention has made the following improvements:
（1）首先在备料工序上，在满足卷烟感官质量设计需要的前提下，一方面选择了钾氯比较高（即钾氯比大于4的烟叶）、成熟度较好的烟叶，另一方面添加了至少5%的造纸法再造烟叶作为烟叶原料，造纸法再造烟叶的感官质量和优质烟叶接近，而且力学性能好、密度小，有利于燃烧，减害降焦效果也较为明显，本发明实验研究中发现，造纸法再造烟叶的添加量必须在5%以上时，才能对烟丝的燃烧性有所改善，提高烟灰颜色的白度，而且随着造纸法再造烟叶添加量的增加，燃烧性会进一步提高，这两方面的改进为烟叶原料的燃烧性奠定了较好的基础；(1) Firstly, in the material preparation process, on the premise of meeting the needs of cigarette sensory quality design, on the one hand, select tobacco leaves with high potassium-chloride ratio (that is, tobacco leaves with a potassium-chloride ratio greater than 4) and good maturity, and on the other hand, add At least 5% of paper-making reconstituted tobacco leaves are used as tobacco raw materials. The sensory quality of paper-making reconstituted tobacco leaves is close to that of high-quality tobacco leaves, and the mechanical properties are good, the density is small, and it is beneficial to combustion. found that the addition of paper-making reconstituted tobacco leaves must be above 5% in order to improve the combustibility of shredded tobacco and increase the whiteness of soot color. Improvement in these two aspects has laid a better foundation for the combustibility of tobacco leaf raw materials;
（2）接下来的真空回潮和松散回潮可以增加烟叶原料的含水率，避免其在后续的工序中破碎；然后在筛分加料过程中，首先筛除长度低于6mm的烟叶或长度低于2mm的叶丝，使得到的叶丝尺寸相对均匀，最终卷制的烟支的燃烧性能也较为均匀，然后均匀施加添加有助燃成分的料液，可以进一步提高烟叶或叶丝的燃烧性；(2) The subsequent vacuum moisture regain and loose moisture regain can increase the moisture content of the raw material of the tobacco leaf and prevent it from being broken in the subsequent process; then in the process of screening and feeding, first screen out the tobacco leaves with a length of less than 6mm or a length of less than 2mm The shredded leaf, so that the size of the shredded leaf is relatively uniform, and the combustion performance of the final rolled cigarette is also relatively uniform, and then the material liquid added with combustion-supporting components can be evenly applied, which can further improve the combustibility of the tobacco leaf or shredded leaf;
（3）后续的处理过程中，通过选择合理的切丝宽度，在0.70mm~1.1mm之间，使叶丝的弹性、松散性和填充值处于适宜的范围；随后的干燥前叶丝增温工序，蒸汽流量和叶丝出料温度对叶丝的弹性、松散性、填充值和含水率均有重要的影响：具体而言，蒸汽流量和叶丝出料温度太高影响卷烟的感官质量；太低则叶丝的膨胀和松散效果不好，叶丝的弹性和松散性变差，从而叶丝的填充值降低，不利于燃烧，但过大的填充值也会增加叶丝的造碎。因此本发明针对干燥前叶丝增温工序进行了长期的实验研究之后，选择了最为适宜的蒸汽流量和叶丝出料温度的控制范围，从而既不会损失卷烟的香气，又能够使叶丝获得较好的弹性、松散性和填充值，提高叶丝的燃烧性；然后进行叶丝干燥，该工序的主要目的是降低叶丝的含水率和提高卷烟的感官质量，使烟丝卷曲定型，原则上含水率低一点对燃烧性有好处，但过低会增加叶丝的造碎，同时抽吸时刺激性增大，口感变差，因此叶丝干燥工序最终的叶丝含水率必须控制在12.0%~12.5%；(3) In the subsequent processing process, by selecting a reasonable cutting width, between 0.70mm and 1.1mm, the elasticity, looseness and filling value of the shredded leaves are in a suitable range; the shredded leaves are warmed before subsequent drying The process, steam flow rate and shredded leaf discharge temperature all have important effects on the elasticity, looseness, filling value and moisture content of the shredded leaf: specifically, the steam flow rate and the shredded leaf discharge temperature are too high to affect the sensory quality of cigarettes; If it is too low, the expansion and loosening effect of the shredded leaves will be poor, and the elasticity and looseness of the shredded leaves will become poor, so the filling value of the shredded leaves will decrease, which is not conducive to combustion, but an excessively large filling value will also increase the shredding of the shredded leaves. Therefore, after the present invention has carried out long-term experimental research on the warming process of the shredded leaves before drying, the most suitable steam flow rate and the control range of the shredded leaf discharge temperature have been selected, so that the aroma of the cigarette will not be lost, and the shredded leaf Obtain better elasticity, looseness and filling value, improve the combustibility of the shredded tobacco; then dry the shredded leaf, the main purpose of this process is to reduce the moisture content of the shredded leaf and improve the sensory quality of the cigarette, so that the shredded tobacco can be curled and shaped. A lower moisture content is good for combustibility, but too low will increase the crushing of shredded leaves, and at the same time, the irritation will increase during suction, and the taste will deteriorate. Therefore, the final moisture content of shredded leaves in the drying process must be controlled at 12.0 %~12.5%;
（4）通过叶丝风选工序可以除去梗签、并条丝、不规则叶丝和杂物，提高叶丝纯净度，剔除不易燃烧的组分，使最后得到的成品烟丝各部分的燃烧性均匀稳定，最终使卷制得到的烟支烟丝密度分布更加均匀，抽吸时烟支各部分均能燃烧完全，在提高了烟灰白度的同时，也保证了烟支燃烧后各部分的白度一致；(4) Stems, drawn wires, irregular shreds and sundries can be removed through the air selection process of shredded tobacco, the purity of shredded leaf can be improved, and non-combustible components can be removed, so that the flammability of each part of the finished cut tobacco can be improved. Uniform and stable, finally making the density distribution of the rolled cigarettes more uniform, and all parts of the cigarette can be completely burned when smoking. While improving the whiteness of the ash, it also ensures the whiteness of each part of the cigarette after burning consistent;
（5）另外也可以在叶丝风选后通过掺配燃烧性能较好的掺配物，例如气流干燥叶丝、膨胀叶丝、膨胀梗丝，进一步提高叶丝的填充值，从而提高其燃烧性，其中的膨胀叶丝和膨胀梗丝也会起到减害降焦的作用，回收烟丝是残烟加工成的回收利用烟丝，一般掺配在同牌号或档次较低卷烟中，减少资源浪费，降低成本；上述掺配物，尤其膨胀叶丝和膨胀梗丝会一定程度的降低卷烟的感官质量，因此该混丝掺配的工序一般用于中低档卷烟的生产过程中；(5) In addition, it is also possible to further increase the filling value of the cut leaves by blending blends with better combustion performance after the air selection of the cut leaves, such as air-dried cut leaves, expanded cut leaves, and expanded cut stems, thereby improving its combustion performance. The expanded shredded leaves and shredded stems will also play a role in reducing harm and reducing coke. Recycled shredded tobacco is recycled shredded tobacco processed from residual tobacco. It is generally blended into cigarettes of the same brand or lower grades to reduce waste of resources , to reduce costs; the above-mentioned blends, especially expanded shredded leaves and expanded stems, will reduce the sensory quality of cigarettes to a certain extent, so this blending process is generally used in the production process of middle and low-grade cigarettes;
（6）通过加香工序，赋予卷烟特征香气，使卷烟香气更优美，改善感官质量，由此得到成品烟丝，本发明的成品烟丝的含水率为12.0%~12.5%，填充值为4.0cm3/g～5.5cm3/g，弹性为3.5%～9.0%；(6) Through the flavoring process, endow the cigarette with characteristic aroma, make the cigarette aroma more beautiful, and improve the sensory quality, thereby obtaining the finished shredded tobacco. The moisture content of the finished shredded tobacco of the present invention is 12.0%~12.5%, and the filling value is 4.0cm3 /g～5.5cm3 /g, the elasticity is 3.5%～9.0%;
（7）最后的烟支卷制工序，卷烟纸和平准器对提高卷烟烟灰的白度和卷烟的感官质量也起到重要的作用，要求具有与成品烟丝相适应的定量和透气度的卷烟纸，保证其与烟丝的阴燃速率相匹配（通过测试烟支的阴燃速率，可以判断卷烟纸和烟丝的阴燃速率是否相匹配），卷烟纸与烟丝的燃烧速度相匹配，基本上可达到同步燃烧，才能获得较为理想的燃烧效果，卷烟纸的透气度大有利于通风燃烧，但同时会稀释烟气量，抽吸后增加灼烧感，吸味受影响，因此选择合适的卷烟纸对改善卷烟的感官质量和提高烟灰的白度意义重大。本发明通过实验研究发现，定量为27g/m2~32g/m2，透气度为50CU~70CU的卷烟纸，可以使得整支卷烟抽吸时卷烟纸的燃烧与烟丝的燃烧相互协调，烟丝燃烧时，卷烟纸能够提供足够的通风量，使烟丝燃烧充分，烟丝燃烧的越充分烟灰越白，同时卷烟香气也会更透发、丰满，满足感更强，焦油释放量和CO释放量更低，降低吸烟者对焦油等有害物质的摄取量；平准器根据烟支规格的不同选择合适的规格，可以获得密度分布均匀的烟支，烟支端部和中部的成品烟丝分布的密度变化率小于11.5%，在保证烟支不空头的前提下，尽量降低烟支卷制重量，烟支重量的降低也可以进一步提高卷烟的燃烧性和改善其感官质量。(7) In the final cigarette rolling process, the cigarette paper and the leveler also play an important role in improving the whiteness of the cigarette ash and the sensory quality of the cigarette, and the cigarette paper with the quantitative and air permeability compatible with the finished tobacco is required , to ensure that it matches the smoldering rate of cut tobacco (by testing the smoldering rate of cigarettes, it can be judged whether the smoldering rates of cigarette paper and shredded tobacco match), and the burning speed of cigarette paper and shredded tobacco matches, basically reaching Simultaneous combustion can achieve an ideal combustion effect. The high air permeability of cigarette paper is conducive to ventilation and combustion, but at the same time it will dilute the amount of smoke, increase the burning sensation after smoking, and affect the taste. Improving the sensory quality of cigarettes and improving the whiteness of ash is of great significance. Through experimental research, the present invention finds that the cigarette paper with a weight of 27g/m2 ~32g/m2 and an air permeability of 50CU~70CU can make the combustion of the cigarette paper and the shredded tobacco coordinate with each other when the whole cigarette is smoked, and the shredded tobacco burns At the same time, the cigarette paper can provide enough ventilation to make the shredded tobacco burn fully, the more fully the shredded tobacco is burned, the whiter the ash, and at the same time, the cigarette aroma will be more transparent and full, and the satisfaction will be stronger, and the tar and CO emissions will be lower. , to reduce the intake of tar and other harmful substances for smokers; the leveler selects the appropriate specification according to the different specifications of the cigarettes, and can obtain cigarettes with uniform density distribution, and the density change rate of the distribution of finished shredded tobacco at the end and middle of the cigarette If it is less than 11.5%, on the premise of ensuring that the cigarettes are not empty, the rolling weight of the cigarettes should be reduced as much as possible. The reduction of the weight of the cigarettes can also further improve the combustibility and sensory quality of the cigarettes.
综上所述，通过本发明所述的方法制成的卷烟不仅明显提高了卷烟烟灰的白度，而且由于燃烧完全，抽吸时有害物质生成的少，焦油释放量和CO释放量有所降低，减少了对人体健康的危害，同时卷烟的感官质量得到改善，抽吸时卷烟的香气更丰满、透发，烟气浓度更高，抽吸后口感更舒适。To sum up, the cigarette made by the method of the present invention not only significantly improves the whiteness of cigarette ash, but also reduces the amount of tar and CO released due to complete combustion and less harmful substances during smoking. , reducing the harm to human health, and at the same time the sensory quality of cigarettes is improved, the aroma of cigarettes is fuller and more transparent when smoking, the smoke concentration is higher, and the taste after smoking is more comfortable.
