Problems solved by technology

The general method is to make certain adjustments by adjusting the heat release curve of the heat source or changing the material of the smoking medium, but it cannot effectively change the fluctuation of the release of the smoking medium during the smoking process.
[0005] 2. In the current heat-not-burn cigarettes, in order to prevent the tobacco from burning, the heating temperature is relatively low, around 300°C, which will lead to limited release of substances required in the smoking medium of heated cigarettes, and the release efficiency is low
In order to increase the release of substances in the smoking medium, the heating temperature is usually raised. At present, the heating temperature has been raised to about 350°C, which makes the temperature resistance of the cigarette paper wrapping the smoking medium higher, otherwise the cigarette paper is easy to carbonize. Broken, it is difficult to remove the smoking medium from the smoking appliance after smoking, which affects the smoking experience

Embodiment 1

[0025] A method for improving the smoking stability of heated cigarettes. The cigarette is prepared by the following operations: the cigarette includes a smoking medium section, and the smoking medium section is prepared by wrapping a smoking medium rod 1 with composite cigarette paper 2, The preparation method of the composite cigarette paper 2 is as follows: it is formed by bonding the first cigarette paper layer 2a, the graphite paper layer 2b and the coating layer 2c through the adhesive layer 2m, and the coating layer 2c and the hair The smoke medium rods 1 are in contact with each other.

[0026] The thickness of the graphite paper layer 2b is 55 μm.

[0027] The second cigarette paper layer used in the coating layer 2c is cigarette paper with a grammage of 40g / ㎡ and an air permeability of 1000CU, and the surface of the coating layer 2c is coated with additives, and the additives include a smoking agent 30wt%, essence 20wt%, gel 50wt%. The purpose of the gel is only to...

Embodiment 2

[0030] The same smoking medium was used to make heated cigarette B with the same structure, and the only difference from heated cigarette A was that the composite cigarette paper 2 of Example 1 was replaced with ordinary cigarette paper. Smoking tests were carried out on heated cigarettes A and B, and the results of the smoke volume during the smoking process of the two cigarettes were as follows: image 3 shown.

[0031] image 3 It shows that when the number of puffs is 7-12, the relative smoke volume of heated cigarette A can still maintain a high level, while the relative smoke volume of heated cigarette B decreases obviously. Therefore, compared with ordinary cigarettes, the cigarette prepared by the method of the present invention has more uniform release of substances required in the smoking process, better suction stability, and no obvious reduction in the amount of smoke that can be sucked up to 12 puffs.

Embodiment 3

[0033] The heated cigarettes A and B of Example 2 were smoke tested, and their nicotine release was tested as shown in Table 1. From the table, it can be seen that the cigarette paper using composite cigarette paper 2 in Example 1 can make the tobacco core base material smoke An increase of about 31.0% in the amount of alkali release can increase the utilization rate of the base material of the tobacco core.

Abstract

The invention belongs to the field of novel heating cigarettes, and particularly relates to a method for improving the smoking stability and the heat utilization rate of a heated cigarette. According to the method, the cigarette is prepared through the following operation, the cigarette comprises a fuming medium section, the fuming medium section is prepared by wrapping a fuming medium rod (1) with composite cigarette paper (2), and the composite cigarette paper (2) is prepared through the following steps that a first cigarette paper layer (2a), a graphite paper layer (2b) and a coating layer (2c) are bonded through an adhesive layer (2m) to form the composite cigarette paper (2), and the coating layer (2c) is in contact with the fuming medium rod (1). According to the invention, the uniformity of substance release in the smoking process is effectively improved, the smoking stability is better, and the amount of smoke which can be smoked by 12 mouths is not obviously reduced.

Description

technical field [0001] The invention belongs to the field of novel heating cigarettes, in particular to a method for improving the smoking stability and heat utilization rate of heating cigarettes. Background technique [0002] In recent years, with the strengthening of the public's awareness of the dangers of cigarettes and the strengthening of government regulations on cigarettes, the international traditional cigarette market has been gradually declining. At the same time, new tobacco products have grown rapidly against the trend. Among them, the sales volume of heated cigarettes is increasing year by year, especially electric heated cigarettes are popular in the market, and its technical maturity and smoking experience are far ahead of other new tobacco products. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] 1. During the heating and smoking process of electric heat...
