Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cigarettes, and in particular, to a cigarette core material, a heat-not-burn cigarette, and a cigarette preparation process. Background Art
[0002] As an important branch of new tobacco products, heat-not-burn cigarettes achieve the core function of heating without burning through precise temperature control technology. Compared with traditional combustible cigarettes and e-cigarettes, heat-not-burn cigarettes have two technical advantages: on the one hand, the non-combustion heating mode significantly reduces the release of harmful components such as tar and carbon monoxide; on the other hand, by directionally releasing the natural tobacco fragrance substances, the smoking experience of traditional cigarettes is retained, and the release amount of tobacco characteristic aroma substances is increased by about 60% compared with e-cigarettes. This unique technical characteristic makes it a focus area of technological innovation in the global tobacco industry. The heat-not-burn cigarette system consists of a cartridge and a heating device. For the cigarette core material of the cartridge, when using a mixed material of cut tobacco, reconstituted stem, and reconstituted tobacco leaf, a liquid containing fragrance and fuming agent is added to the material, and then it is rolled into a cartridge. However, there is heterogeneity among the materials of the three structures of cut tobacco, reconstituted stem, and reconstituted tobacco leaf, and there are differences in the adsorption performance of the three parts of the material for the liquid, which leads to uneven distribution of the liquid in the overall mixed material, resulting in uneven release of the fuming agent during the smoking process of the cartridge and seriously affecting the smoking sensory experience. Summary of the Invention

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0026] As Figure 1 - Figure 2 shown, the embodiments of the present application provide a cigarette core material, a heat-not-burn cigarette and a cigarette preparation process, which are applied in the field of heat-not-burn cigarettes. A heat-not-burn cigarette is a new type of cigarette product, which usually includes a cartridge and a heating device. The cartridge is heated by the heating device, and the cartridge is only heated but does not burn. The cigarette core material of the cartridge is added with spices and a smoke agent, and aroma substances are atomized after being heated. Since the cartridge is only heated but does not burn, the release amounts of harmful components such as tar and carbon monoxide are significantly reduced. Moreover, by directionally releasing the tobacco natural fragrance substances, the suction experience of traditional cigarettes is retained. The release amount of its tobacco characteristic aroma substances is increased by about 60% compared with that of e-cigarettes. The cigarette core material of the cartridge is usually a mixture of cut tobacco, reconstituted stem and reconstituted tobacco leaf. The three components that make up the mixed material are heterogeneous, and the adsorption effects of the three materials on the liquid material containing spices and a smoke agent are different. Therefore, the overall distribution of the liquid material in the cigarette core material is not uniform. So during heating and suction, the smoke agent cannot be atomized and released evenly to produce aroma, which will affect the suction sensory experience. The cigarette core material, heat-not-burn cigarette and cigarette preparation process provided by the present application aim to improve the distribution uniformity of the liquid material added to the cigarette core material and enhance the overall suction sensory experience.
[0027] An embodiment of the present application provides a cigarette core material, which includes a cigarette core material body 100. The cigarette core material body 100 is composed of filamentous tobacco materials, stem-like tobacco materials, and flaky tobacco materials. The filamentous tobacco materials, stem-like tobacco materials, and flaky tobacco materials described here are all tobacco product items. The filamentous tobacco materials are filamentous tobacco product items, such as cut tobacco. The stem-like tobacco materials are reconstituted stem shreds, and the flaky tobacco materials are flaky tobacco product items, that is, reconstituted tobacco leaves. The mixing ratio of the filamentous tobacco materials, stem-like tobacco materials, and flaky tobacco materials can be determined according to actual production requirements. The cigarette core material also includes a sizing agent, which is provided on the cigarette core material body 100. The function of the sizing agent is to improve the wettability of the cigarette core material body 100. Due to the heterogeneity among the filamentous tobacco materials, stem-like tobacco materials, and flaky tobacco materials, there are significant differences in the adsorption effect of the liquid to be added. By adding the sizing agent to the cigarette core material body 100, the wettability of the filamentous tobacco materials, stem-like tobacco materials, and flaky tobacco materials is improved, the heterogeneity difference is reduced, the adsorption effect on the liquid is more similar, and further the distribution uniformity of the liquid in the overall cigarette core material body 100 is improved. When the cigarette product is heated and puffed, the atomization and smoking uniformity of the smoke agent are improved, which is beneficial to improving the puffing sensory experience.
[0028] Preferably, the sizing agent includes 1,2-propanediol, glycerol, ethanol, and water, and the mass ratio of 1,2-propanediol, glycerol, ethanol, and water is 1-5∶1-2∶1-5∶88-97.
[0029] More preferably, the sizing agent is sprayed on the cigarette core material body 100 to make the distribution of the sizing agent in each component of the cigarette core material body 100 more uniform. In this embodiment, the sizing agent is evenly sprayed on the three parts of the filamentous tobacco materials, stem-like tobacco materials, and flaky tobacco materials that make up the cigarette core material body 100, reducing the heterogeneity of the three parts of the materials and making the adsorption effect on the liquid to be added more uniform.
[0030] An embodiment of the present application also provides a heat-not-burn cigarette, that is, a cartridge. The heat-not-burn cigarette includes the above-mentioned cigarette core material, and also includes a filter tip 300 and cigarette paper 200. The cigarette paper 200 is wound around the outside of the cigarette core material to form a cigarette core section, and the cigarette core section is connected to the filter tip 300. The cigarette paper 200 wraps around the outer periphery of the cigarette core material body 100 to form a cylindrical cigarette core section, and the cigarette core section and the filter tip 300 are coaxially connected. The filter tip 300 can be a composite filter rod, and the cigarette paper 200 can be the permeable paper in the cigarette product.
[0031] An embodiment of the present application also includes a cigarette preparation process for preparing the above-mentioned heat-not-burn cigarette, and this process includes the following steps:
[0032] A. Prepare filamentous tobacco materials, stem-like tobacco materials, and flaky tobacco materials, and mix them to obtain the cigarette core material body 100;
[0033] B. Add sizing agent to the tobacco core material body 100 obtained in step A to improve the wettability of the tobacco core material body 100;
[0034] C. Add flavor liquid to the tobacco core material body 100 processed in step B;
[0035] D. Roll the tobacco core material processed in step C together with cigarette paper 200 and filter tip 300 into a heat-not-burn cigarette.
[0036] Preferably, in step C, the flavor liquid is sprayed on the tobacco core material body 100 to make the distribution of the flavor liquid in the tobacco core material body 100 more uniform.
[0037] More preferably, the flavor liquid includes flavor components and a fuming agent. The flavor components can be lemon, dried tangerine peel, mint, etc., and the fuming agent is a mixture of glycerol and propylene glycol.
[0038] In one example, the flavor liquid further includes a complexing aid. The flavor liquid includes flavor components, a fuming agent, and a complexing aid. The complexing aid is used to enhance the intermolecular force between fuming agent molecules. The complexing aid forms a complex with the fuming agent. The complex increases the intermolecular interaction between fuming agent molecules. The originally relatively free fuming agent molecules are combined more tightly through complexation. When the cigarette is heated, a greater intermolecular force needs to be overcome to volatilize the fuming agent, thus effectively slowing down the release rate of the fuming agent, enabling the fuming agent to be released continuously and stably for a longer time, extending the usage duration of the heat-not-burn cigarette, and allowing consumers to enjoy a relatively consistent aroma and taste throughout the smoking process.
[0039] The complexing aid includes one or more of calcium chloride, calcium sulfate, calcium gluconate, magnesium chloride, magnesium sulfate, magnesium hydroxide, aluminum chloride, and aluminum sulfate.
[0040] In some examples, the flavor liquid further includes a heat conduction aid. The flavor liquid includes flavor components, a fuming agent, a complexing aid, and a heat conduction aid. The heat conduction aid is used to improve the heat conduction efficiency of the tobacco core material body 100. The heat conduction aid constructs a heat conduction network on the surfaces of filamentous tobacco materials, stem-like tobacco materials, and sheet-like tobacco materials. When the heat-not-burn cigarette is heated, heat can be quickly and evenly transferred to each part through the heat conduction network, effectively improving the heat conduction performance. The stable and uniform heat transfer enables the fuming agent to be evenly released in the heated environment, and the entire tobacco core material body 100 is heated more evenly, avoiding the phenomenon of uneven atomization and fuming caused by local temperature differences, thus bringing a more stable and uniform smoking experience to consumers.
[0041] The heat conduction aid includes one or more of aluminum oxide, magnesium oxide, zinc oxide, aluminum nitride, boron nitride, silicon carbide, graphene, and carbon nanotubes.
