Problems solved by technology

[0004] In order to solve the technical problems such as the high temperature of the mainstream smoke of the existing cigarettes, especially the mainstream smoke of the last two puffs, which is likely to bring a burning sensation and an uncomfortable aftertaste, the present invention provides a cigarette that uses Na 2 HPO 4 12H 2 The application of O as a cigarette cooling material in reducing the temperature of mainstream smoke in cigarettes aims to reduce the temperature of mainstream smoke, thereby improving the sensory evaluation results of cigarettes and improving the smoking experience of cigarettes

Embodiment 1

[0031] Weigh 20 mg of ground Na 2 HPO 4 12H 2 O, add it to the tobacco end of the cigarette filter rod, and combine the cigarette with the filter rod to make the filter cigarette experimental sample (Experimental Sample), smoke in the ISO mode on the Smoking Machine SML 100 smoking machine, and use it on the LIBERSON TF-M100 The flue gas temperature data is detected and collected on the thermocouple device, and the thermocouple probe is inserted at 7mm from the flue gas outlet end of the filter. Na not added 2 HPO 4 12H 2 The same cigarette of O is blank sample fEmptySample).

[0032] The experimentally measured mainstream smoke change curve is as follows: figure 1 shown. Depend on figure 1 It can be seen that before 150 seconds, there is almost no difference in the mainstream smoke temperature between the test sample cigarette and the blank sample cigarette. After 150 seconds, the mainstream smoke temperature of the blank sample gradually increased, reaching around 3...

Embodiment 2

[0035] According to the description in Example 1, 10mg, 20mg, 30mg, 40mg, 60mg, 70mgNa 2 HPO 4 12H 2 O’s filter cigarettes, and detect and collect mainstream smoke temperature data, and organize the data in Table 1

[0036] Table 1 Add 10mg to 70mg Na 2 HPO 4 12H 2 O filter cigarette mainstream smoke temperature data

[0037]

[0038] by the embodiment figure 1 It can be seen that the mainstream smoke temperature of the blank cigarette is 33°C, 76°C, and 78°C, respectively, at the third-to-last puff, second-to-last puff, and first-to-last puff. Added 10mg to 70mg Na 2 HPO 4 12H 2 O filter cigarettes, the temperature of the penultimate puff of mainstream smoke showed a trend change between 41°C and 22.5°C, and decreased significantly, among which the temperature of 70mg was the lowest at 22.5°C; Higher at 41°C, but significantly lower than the blank cigarette. The temperature of the penultimate puff and the penultimate puff of the mainstream smoke, the experimenta...

Embodiment 3

[0040] The experimental cigarettes in Example 2 and the blank cigarettes in Example 1 were evaluated.

[0041] When burning and smoking, the blank sample cigarette has the smallest draw resistance, add 10mg Na 2 HPO 4 12H 2 The draw resistance of O cigarettes is close to that of blank cigarettes, adding 20mg Na 2 HPO 4 12H 2 The draw resistance of cigarettes with O was slightly larger than that of the blank cigarettes, and the draw resistance of the experimental cigarettes further increased with the further increase of the added amount. When it was increased to 40 mg, the draw resistance of the cigarettes was relatively large, and when it was increased to 60 mg, it was difficult to smoke. Therefore, without redesigning the filter tip, it is better to add 40 mg or less. In the case of reducing the pressure drop of the blank filter itself, the addition amount can be increased appropriately.

[0042] In terms of cigarette sensory quality, add 10mg Na 2 HPO 4 12H 2 The ci...

Abstract

The invention discloses a cigarette of which the temperature of main stream smoke, particularly the temperature of the last two puffs of smoke, is remarkably reduced. Na2HPO4.12H2O is added in a filter tip of the cigarette, the temperature of the last two puffs of smoke can be reduced to be 30 DEG C or below from the general temperature of 70 DEG C, burning in mouth of the last two puffs of smoke is reduced remarkably, and the cigarette has the advantages of small addition amount, low economic cost and the like.

Description

technical field [0001] The invention relates to the technical field of cigarette product materials, in particular to a cigarette filter tip added with a cooling material, a cigarette and its application in reducing the temperature of mainstream smoke of the cigarette. Background technique [0002] When smoking cigarette products, because the first few puffs of smoke flow through the cigarette tobacco column and filter, the path is longer and the cooling time is longer. to more comfortable. However, with the shortening of the tobacco column, especially in the last 2 to 3 puffs, the path of the mainstream smoke is significantly shortened, and the cooling time is significantly shortened. ℃ to 80 ℃, the smoker feels a strong burning sensation in the mouth, and the aftertaste in the mouth is uncomfortable, which affects the pleasure of smoking. [0003] The Chinese patent document with the publication number CN105686078A discloses a cigarette cooling agent and its application. ...
