Abstract

The invention relates to a cigarette with a temperature regulating function, comprising a filter rod and a shredded tobacco rod. A thermal conductor is arranged in the shredded tobacco rod, and the thermal conductor is arranged along the longitudinal direction of the shredded tobacco rod. Rod cross section. In the cigarette with temperature regulating function of the present invention, since a thermal conductor is arranged longitudinally in the shredded tobacco rod, when the cigarette is burned and smoked, the heat of the combustion cone can be absorbed by the thermal conductor and transferred to the shredded tobacco around the thermal conductor, thereby increasing the temperature of the shredded tobacco. The temperature of the non-combustion part in the middle increases the thermal distillation effect of the flue gas, thereby increasing the transfer rate of volatile and semi-volatile tobacco aroma substances and added flavors and fragrances to the flue gas. At the same time, since the heat of the combustion cone is absorbed by a good thermal conductor, the temperature of the combustion cone can be reduced by 100-200°C from 900-1100°C in the prior art, which can greatly reduce the release of harmful substances, while the release of fragrance substances is reduced The magnitude is small.

Description

Cigarette with temperature regulating function

technical field

The invention relates to the technical field of cigarette manufacture, in particular to a cigarette with a temperature regulating function.

Background technique

In the shredded tobacco rod of cigarettes in the prior art, the shredded tobacco has its own aroma substances or flavors and fragrances added, which can improve the taste of the cigarette when it is burned and smoked. When the cigarette is burned and smoked, when the smoke passes through the non-combustion part, it will produce a thermal distillation effect on the shredded tobacco, and the volatile substances or semi-volatile substances in the shredded tobacco and the added flavors and fragrances 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. 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. However, since most of the essences are relatively easy to volatilize, adding fragrance directly to the filter stick will easily cause the essence to be lost due to volatilization during storage, reducing the effect of adding essence. 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, since 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 rod, there are How to balance the issue of release and preservation: If the bonding force between the material and the flavor is strong, the flavor will have strong stability in the cigarette filter rod and a long storage time, but the problem will be that the release efficiency of the cigarette is low; if the material The combination with the essence is weak, and the essence is easier to release when the cigarette is smoked, but the essence is easily volatile and lost when the cigarette is 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.

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.

Preferably, the thermal conductor is a columnar body or a twisted strip formed by twisting two or more monomers. (Cylinder shape includes cylinder and prism)

Preferably, the minimum distance between the end of the good thermal conductor close to the filter rod and the filter rod is 0-20mm.

Preferably, one end of the thermal conductor protrudes into the filter rod, the part of the thermal conductor protruding into the filter rod has a length of 0 mm to 20 mm, and the part of the thermal conductor protruding into the filter rod is The distance between the end and the outlet end of the filter rod is more than 5mm.

Preferably, the thermal conductor has a circular cross section with a diameter of 1-3mm.

Preferably, the thermal conductor has a square or rhombus cross-section with a side length of 1-3 mm.

Preferably, the thermal conductor is arranged at the longitudinal center of the shredded tobacco rod.

Preferably, the thermal conductor is made of gold or silver or platinum or aluminum or iron or an alloy or an alloy with carbon added.

Compared with the prior art, in the cigarette with temperature regulating function of the present invention, since the heat conductor is arranged longitudinally in the shredded tobacco rod, when the cigarette is smoked, the heat of the combustion cone can be absorbed by the heat conductor and transferred to the heat conductor. The shredded tobacco around the conductor increases the temperature of the non-combustible part of the shredded tobacco and improves the thermal distillation effect of the smoke, thereby increasing the transfer rate of volatile and semi-volatile tobacco aroma substances and added flavors and fragrances to the smoke. At the same time, since the heat of the combustion cone is absorbed by a good thermal conductor, the temperature of the combustion cone can be reduced by 100-200°C from 900-1100°C in the prior art, which can greatly reduce the release of harmful substances, while the release of fragrance substances is reduced The magnitude is small.

In the cigarette with temperature regulating function of the present invention, since one end of the thermal conductor is placed close to the filter rod or inserted into the filter rod, the heat of the combustion cone when the cigarette is smoked can be indirectly or directly transferred to the filter rod through the thermal conductor Microcapsules, porous adsorption materials, dripping pills, etc., so that the essence can be released at a higher temperature. The cigarette with the temperature regulating function of the present invention can not only meet the stability problem of volatile essence in cigarette storage, but also can fully release the essence in the process of cigarette burning and smoking, and improve the utilization rate of essence.
