Filter stick additive capable of reducing smoke temperature of heat-not-burn cigarette and preparation method of filter stick additive

Abstract

The invention discloses a filter stick additive capable of reducing smoke temperature of a heat-not-burn cigarette and a preparation method of the filter stick additive. An AKD (alkyl ketene dimer) istaken as a cooling component, sodium alginate, silica gel and tobacco particles are taken as a support, a supported cooling material is obtained by supporting the cooling component on the support surface with an impregnation method, the supported cooling material is added to a cigarette filter stick for preparing a composite filter stick, the heat-not-burn cigarette is formed by rolling connection, the smoke temperature is tested, and experimental data proves that the smoke temperature of the heat-not-burn cigarette containing the supported material can be reduced effectively. The preparationmethod of the filter stick additive for the low-temperature heat-not-burn cigarette is simple, and industrial mass production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of cigarette preparation, and in particular relates to a filter rod additive capable of reducing the smoke temperature of heat-not-burn cigarettes and a preparation method thereof. Background technique [0002] Heat-not-burn cigarettes use external heating elements to heat the tobacco substance. The shredded tobacco or thin sheet is only heated but not burned. The atomization medium in the cigarette, the flavor components in the tobacco and the additional flavoring substances are heated to produce smoke, which is harmful The release of chemical components is significantly reduced. At present, the mainstream heat-not-burn cigarettes on the market include Philip Morris’ iQOS and British American Tobacco’s glo. The temperature at which the gas enters the mouth through the filter section will be higher than the temperature at which ordinary cigarettes burn, resulting in overheating of the smoke at the entrance....

AI Technical Summary

Problems solved by technology

At present, the mainstream heat-not-burn cigarettes on the market include Philip Morris’ iQOS and British American Tobacco’s glo. The temperature of the gas entering the mouth through the filter section will be higher than the burning temperature of ordinary cigarettes, resulting in overheating of the entrance smoke, and there is still a big gap with traditional cigarettes in terms of smoking experience and smoking experience

[0003] The existing technology mainly uses phase-change cooling materials to cool the high-temperature flue gas that flows vertically. For example, the material of the cooling section of iQOS is mainly polylactic acid (PLA) sheets that are wrinkled, pleated, gathered and folded. The limitation of length and phase-change cooling material, and the relatively fast flow rate of smoke make it difficult to cool down the material; the lateral heat transfer of overheated smoke through the mouthpiece makes consumers feel like burning their lips when they smoke.

In addition, PLA flakes, a phase-change cooling material, will melt when exposed to high-temperature flue gas, which will block the flue gas passage, affect the cooling effect of the material, and even lead to a significant reduction in the amount of smoke
