Description
Technical Field
The invention belongs to the technical field of tobacco preparation, and particularly relates to a cigarette with a porous material for improving the combustion performance of the cigarette and a preparation method thereof.
Background
At present, two conventional methods for improving the combustion performance of cigarettes are mainly used, wherein the first method is to improve the combustion performance of tobacco shreds by adding feed liquid containing a combustion improver into tobacco leaves, and the second method is to improve the combustion performance of cigarettes by using cigarette paper with high air permeability.
Tobacco leaves with poor combustion performance can increase the number of cigarette suction openings, increase the release amount of tar, and often extinguish cigarettes in static combustion. The combustion improver is used in the cigarette to change the combustion condition of the cigarette to promote the combustion of tobacco shreds, so that the cigarette is fully combusted, the ashing is complete, and the number of suction openings of each cigarette is reduced, thereby reducing the generation amount of smoke particle phase substances (tar) when the cigarette is smoked every time. Meanwhile, the combustion improver can also improve the combustion rate of the cigarettes during static combustion and smoking combustion and reduce the number of smoking openings of the cigarettes. Most of the combustion improvers commonly used in tobacco are alkali metal salts of organic acids, such as potassium tartrate, potassium citrate, sodium citrate, potassium carbonate, etc. However, almost all combustion improvers have various degrees of influence on the smoking taste of cigarettes, and thus the amount thereof to be used needs to be effectively limited.
The static combustion rate of the cigarette can be improved by using the high natural air permeability, the static combustion rate of the cigarette is accelerated along with the increase of the natural air permeability of the cigarette paper, so that the number of suction openings of the cigarette is reduced, the tar content in the smoke is reduced, and when the natural air permeability is increased to 80-100 CU, the static combustion rate of the cigarette is stable and does not influence the static combustion rate of the cigarette any more. When the natural air permeability of the cigarette paper reaches a certain degree, the smoking speed of the cigarettes is reduced, the number of the smoking openings of the cigarettes is increased reversely, and therefore the tar content is increased.
After the cigarette is ignited, carbon is generated at the first end, and the burning solid matter forms a cone, namely a burning cone. During suction, the combustion temperature is highest around the bottom of the combustion cone, most of the air flow passes through the bottom, and a dense and airtight carbonized body is formed in the middle of the combustion cone, and the air flow cannot easily pass through the carbonized body, so that the blockage effect is realized. In this case, combustion mainly occurs around the combustion cone, and combustion is performed under oxygen-rich conditions. And the interior of the combustion cone is effectively an oxygen-free zone throughout the pumping cycle, resulting in a significant increase in the concentration of carbon monoxide in the combustion cone. Meanwhile, insufficient oxygen supply in the combustion cone can cause insufficient combustion, so that a plurality of cracking reactions can occur, a plurality of complex particle-phase substances can be generated, and aromatic hydrocarbons and polycyclic aromatic hydrocarbons can be easily generated.
Disclosure of Invention
In view of the above, the invention provides a cigarette using porous material to increase the combustion performance of the cigarette and a preparation method thereof, wherein a porous material cylindrical rod filled with pores and having a high surface area is rolled and packaged inside the cigarette, the porous material cylindrical rod penetrates through the whole tobacco shred section and the preceding stage filter rod section, and the cigarette has the characteristics of small suction resistance, high oxygen content, sufficient tobacco shred combustion, less generated tar and the like during smoking, thereby effectively solving the defects of large suction resistance, no air circulation, less oxygen content, insufficient tobacco shred combustion, higher tar and harmful component release and the like caused by compact combustion cone of the traditional cigarette during burning and smoking.
The invention relates to a cigarette for increasing the combustion performance of the cigarette by utilizing a porous material, which comprises a rear-stage filter stick, a front-stage filter stick and a primary cigarette section, wherein the front-stage filter stick and the primary cigarette are wrapped and connected through tipping paper 1 to obtain a second cigarette, the rear-stage filter stick and the second cigarette are wrapped and connected through tipping paper 2, the cigarette further comprises a porous cylindrical rod wrapped in the second cigarette, and the porous cylindrical rod is formed by connecting a plurality of cylindrical rods of which the two ends are in one of a conical shape and a wedge shape in series.
Preferably, the material of the porous cylindrical rod is one of a silicon-based porous material and a non-silicon-based porous material.
Preferably, the porous cylindrical rod is one or two of a silicon oxide porous cylindrical rod and an aluminum silicate porous cylindrical rod.

(1) the tobacco shreds are rolled into a filter-rod-free primary cigarette section by using the cigarette paper, so that fine bamboo sticks, metal wires and other articles can be pre-buried in the tobacco shreds in the process of rolling the tobacco shreds into the filter-rod-free primary cigarette, and after the primary cigarette is made, the pre-buried articles are drawn out to form the primary cigarette with a certain fine cavity;
(2) cutting the cylindrical rod into cylindrical rods with the same length and different widths, and connecting a plurality of cylindrical rods in series to form a plurality of cylindrical rods
The two ends of the porous cylindrical rod can be cut into conical and wedge shapes so as to be connected in series, so that the porous cylindrical rod can be formed by cylindrical rods made of different materials and having different porous properties, thus, the porous cylindrical rods at different positions can have different air-guiding capacities, because the air circulation of the tobacco is poorer at the position closer to the cigarette holder in the smoking process, the air circulation of the internal space of the part close to the cigarette holder is improved, the uniform distribution of the oxygen content can be facilitated, the generation of harmful substances caused by insufficient combustion is avoided, and in addition, the mode of serial splicing is adopted, when the cigarette is burnt, the porous cylindrical rod can fall off one section by one section along with the burning of the cigarette, and a long central rod with temperature cannot be left after the cigarette is completely burnt so as to avoid scalding consumers;
(3) inserting a porous cylindrical rod into the front-stage filter stick and the primary cigarette section, and rolling and connecting through tipping paper 1 to obtain a secondary cigarette, wherein the widths of the porous cylindrical rod from the front-stage filter stick to the primary cigarette section are sequentially reduced;
(4) and (4) using the tipping paper 2 to splice the post-stage filter stick and the secondary cigarette again to finally obtain the cigarette containing the porous cylindrical stick.

In the aspect of improving the combustion performance of cigarette, change the local structure of burning awl (because porous cylinder stick can not burn when cigarette tobacco burns, can rely on porous cylinder stick when the tobacco burns, and the porosity of porous cylinder stick can improve richer oxygen simultaneously, does benefit to the homogeneous combustion, and most air current passes through from the bottom, and burning awl middle part sets up many empty materials, can not form a compact airtight carbide, and the air current can pass through from here), make inside and outside intercommunication, increase inside specific surface area, increase circulation of air and oxygen exchange.
The porous material is a material with a network structure formed by interconnected or closed pores. Compared with continuous medium materials, porous materials generally have the advantages of low relative density, high specific strength, high specific surface area, light weight, sound insulation, heat insulation, good permeability and the like. The porous material has large specific surface area, adsorption capacity and many special properties, and is widely applied to the fields of adsorption, separation, catalysis and the like. The porous material is wrapped in the tobacco shreds, the internal structure of the combustion cone is changed during combustion, the air circulation and the oxygen supply are increased, and the combustion performance of the cigarette is improved.
