Description

A kind of preparation method and application of cooling cigarette

technical field

The invention belongs to the field of cigarette manufacturing, in particular to a preparation method and application of a cooling cigarette.

Background technique

When cigarettes burn, they will produce a lot of harmful substances, such as tar, benzene, etc., which will endanger the health of smokers and surrounding people in serious cases. Therefore, how to reduce the release of harmful substances from cigarettes is an urgent problem. The technical difficulty in reducing coke and harm of cigarettes is that it is necessary to effectively reduce the tar and harmful substances produced by the combustion of cigarettes, and to reasonably control the extent of coke reduction, so as to ensure that the overall sensory style of cigarettes can meet the tastes of consumers. In the existing cigarette technology, the cut tobacco has its own flavor substances or flavors and fragrances are added to the cut tobacco, so as to improve the smoking taste of the cigarette during smoking. When the cigarette is burned, when the smoke passes through the unburned part, it will have a thermal distillation effect on the cut tobacco, and the volatile or semi-volatile substances in the cut tobacco and the added flavors and fragrances will be transferred into the smoke, but the transfer rate is low. Relevant studies have shown that reducing the temperature of the cigarette burning cone can greatly reduce the release of harmful substances and increase the temperature of the non-burning part of the cigarette. Improving the distillation effect is beneficial to the release of semi-volatile aroma components, and with the decrease of the combustion cone temperature, the amount of aroma substances released is very small.

At present, the specific methods for reducing coke and harm of cigarettes mainly start from the raw materials of tobacco leaves, such as leaf group formula, "three papers and one stick" and online production processes. The above methods achieve the effect of reducing coke and harm through the integration of physical, chemical and biological means and various supporting technologies. In the prior art, the coke reduction technology mainly adjusts the burning state of the cut tobacco by adding additives to the cut tobacco.
