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

Example Embodiment

[0018] Example 1

[0019] Take 1000g of 15% AKD suspension with solid content and pour it into a beaker, then add 850g of 20-100 mesh silica gel particles, stir and immerse for 8h, then dry in a drying oven at 105℃ for 4h, cool to room temperature naturally, sieving, and take 20-100 mesh particles, namely AKD / silica gel, put them in the drying box for later use. According to the above preparation method, the AKD suspension was replaced with deionized water, and the other processes were the same to prepare control silica gel particles.

[0020] The prepared additive was added to the cigarette filter at 30mg / stick. The smoke test results showed that the maximum temperature of heat-not-burn cigarette smoke containing AKD / silica gel material was 25.5℃ lower than the maximum temperature of heat-not-burn cigarette smoke containing control silica gel material.

Example Embodiment

[0021] Example 2

[0022] According to the method of Example 1, the silica gel carrier was replaced with tobacco particles. Others are the same, and AKD / tobacco particulate material is prepared.

[0023] The prepared additive was added to the cigarette filter at 30mg / stick. The smoke test results showed that the maximum temperature of heat-not-burn cigarettes containing AKD / tobacco particulate material was 28.5 lower than the maximum temperature of heat-not-burn cigarettes containing control tobacco particulate material ℃.

Example Embodiment

[0024] Example 3

[0025] According to the method of Example 1, the silica gel carrier was replaced with sodium alginate. Others are the same, and AKD / sodium alginate granular material is prepared.

[0026] The prepared additive was added to the cigarette filter at 30mg / stick. The smoke test results showed that the highest smoke temperature of the heat-not-burn cigarette containing AKD / sodium alginate particulate material was higher than that of the heat-not-burn cigarette smoke containing the control sodium alginate particulate material The maximum temperature is 24.3℃ lower.

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....
