可调整燃吸过程中烟支温度的卷烟Cigarette with adjustable cigarette temperature during burning and smoking

技术领域technical field

本发明涉及卷烟的制造技术领域，尤其涉及一种可调整燃吸过程中烟支温度的卷烟。The invention relates to the technical field of cigarette manufacture, in particular to a cigarette which can adjust the temperature of cigarettes during burning and smoking.

背景技术Background technique

现有技术的卷烟烟丝棒中，烟丝自带香味物质或添加香精香料，这都能改善卷烟燃吸时的吸味，卷烟在燃吸时，烟气经过非燃烧部分时，会对烟丝产生热蒸馏效果，烟丝中的挥发性物质或半挥发性物质以及外加香精香料会转移到烟气中，但转移率不高。同时，有关研究表明，如发表在《理化检验-化学分册》上的“裂解气相色谱-质谱联用法分析卷烟燃吸产物”一文中提到，降低卷烟燃烧锥温度，可大幅降低有害物质释放量，且提高卷烟非燃烧部分的问题，提高蒸馏效应，有利于半挥发性香气组分的释放；而《烟草科技》上“卷烟烟丝热裂解产物香味成分分析”的数据则显示，随燃烧锥温度降低，香味物质释放量降低幅度很小。由此可见，如何对现有技术中的卷烟进行结构改进，降低卷烟燃烧锥温度，以降低烟气中有害物质的释放量，并提高烟丝中的挥发性物质或半挥发性香味物质以及外加香精、香料转移到烟气的转移率，这是本领域目前需要解决的技术问题。In the shredded tobacco rods of the prior art, the shredded tobacco has its own flavoring substances or flavors and fragrances added, which can improve the taste of the cigarette when it is burned and smoked. Due to the distillation effect, the volatile or semi-volatile substances in the shredded tobacco and the added flavor and fragrance will be transferred to the smoke, but the transfer rate is not high. At the same time, relevant studies have shown that, as mentioned in the article "Analysis of Cigarette Smoking Products by Pyrolysis Gas Chromatography-Mass Spectrometry" published in "Physical and Chemical Testing-Chemistry Volume", reducing the temperature of the cigarette burning cone can greatly reduce the release of harmful substances , and improve the problem of non-combustible parts of cigarettes, improve the distillation effect, and facilitate the release of semi-volatile aroma components; and the data of "Analysis of Aroma Components in Cigarette Shredded Tobacco Pyrolysis Products" in "Tobacco Science and Technology" shows that with the combustion cone temperature The reduction in the release of aroma substances is very small. It can be seen that how to improve the structure of cigarettes in the prior art, reduce the temperature of the cigarette burning cone, reduce the release of harmful substances in the smoke, and increase the volatile substances or semi-volatile flavor substances and the added essence in the shredded tobacco. 1. The transfer rate of spices transferred to smoke, which is a technical problem to be solved in this field at present.

此外，现有技术中，在滤棒中直接或间接添加香精，以掩盖烟草燃烧中产生的辛辣感，在烟气中增加新的香气，改善和提升卷烟品质。由于大部分香精均较容易挥发，所以在滤棒中直接加香，易造成香精在储存期间因挥发而散失，降低香精的添加效果。为了解决滤棒直接加香不易保存的问题，近几年发展起来在滤棒中间接加香的方法，例如微胶囊、多孔缓释材料、滴丸等。对于微胶囊和多孔缓释材料的加香方式，由于都是利用吸烟过程中热的烟气（温度在40℃~50℃）通过滤嘴使预先包埋或吸附的香精释放出来，所以都存在如何平衡释放和保存问题：如果材料和香精之间结合力强，则香精在卷烟滤嘴中稳定性强，保存时间长，但会带来的问题是卷烟燃吸时的释放效率低；如果材料和香精之间结合力弱，卷烟燃吸时香精较易释放，但在卷烟保存时香精易挥发而损失。而对于采用滴丸的加香方式，则是通过物理力捏破滴丸使香精释放，从目前市场上看，中国消费者对这种加香方式接受程度不高。In addition, in the prior art, essence is directly or indirectly added to the filter rod to cover up the pungent feeling produced in the burning of tobacco, add new aroma to the smoke, and improve and enhance the quality of cigarettes. Since most of the flavors are relatively easy to volatilize, adding fragrance directly to the filter stick will easily cause the flavor to be lost due to volatilization during storage, reducing the effect of adding flavor. In order to solve the problem that the filter rod is not easy to preserve after directly adding fragrance, in recent years, methods of indirectly adding fragrance to the filter rod have been developed, such as microcapsules, porous slow-release materials, dripping pills, etc. For the flavoring methods of microcapsules and porous slow-release materials, because they all use the hot smoke (temperature between 40°C and 50°C) in the smoking process to release the pre-embedded or adsorbed essence through the filter, so there are some problems. Balanced release and preservation: If the binding force between the material and the flavor is strong, the flavor will be stable in the cigarette filter and the storage time will be long, but the problem will be that the release efficiency of the cigarette is low; if the material and flavor The binding force between the flavors is weak, and the flavors are released easily when the cigarette is smoked, but the flavors are easily volatilized and lost when the cigarettes are stored. For the flavoring method using dripping pills, the essence is released by pinching the dropping pills with physical force. From the current market, Chinese consumers do not accept this flavoring method very much.

由此可见，如何对现有技术中的烟支进行结构改进，使得采用间接加香方式的卷烟，其中稳定的已包裹或吸附了香精的微胶囊、多孔吸附材料、滴丸等在卷烟燃吸过程中香精能够有效释放，这也是本领域目前需要解决的技术问题。It can be seen how to improve the structure of cigarettes in the prior art, so that cigarettes using indirect flavoring methods, in which stable microcapsules, porous adsorption materials, dripping pills, etc. that have wrapped or absorbed flavors, etc. Essence can be effectively released during the process, which is also a technical problem to be solved in this field.
