Description

Technical Field

[0001] The invention relates to the technical field of tobacco, and in particular to a method for preparing a tobacco column component, a filter rod, and a heat-not-burn cigarette. Background Art

[0002] With the advancement of science and technology and the general improvement of people's health awareness, tobacco products have shown a blowout development. The more prominent representatives include heat-not-burn cigarettes, which mainly use tobacco materials such as cigarettes, tobacco or tobacco sheets filled in special electric heating devices, and the smoke in the tobacco filling materials is volatilized through electric heating, so that smokers can get a similar smoking experience to traditional tobacco, and the smoke temperature is below 300°C. Since heat-not-burn cigarettes use tobacco raw materials or reconstituted tobacco leaves, and the amount used is small, and the tobacco does not burn, the concentration of smoke aroma is weaker than that of traditional cigarettes. In addition, due to its relatively small size, there is no long unburned cigarette section and filter rod similar to traditional cigarettes for cooling and cooling. The inlet temperature of its smoke will be much higher than that of traditional cigarettes, which will produce obvious hot burning and spicy stimulation to consumers. Therefore, for heat-not-burn cigarettes, while ensuring its cooling performance, it is a key technology for preparing heat-not-burn cigarettes to have a relatively excellent and lasting flavor enhancement effect.

[0003] At present, most of the heat-not-burn cigarette products on sale use multi-component composite filter rods to achieve the cooling effect. For example, IQOS uses a three-component composite filter rod, which consists of a hollow filter section, a cooling section, and a filter section. The hollow filter section is used to separate the heating plate and the cooling section, and the cooling section uses a cooling film to achieve the cooling effect. However, conventional multi-component composite filter rods cannot achieve the smoking experience of reducing harm and tar, and increasing flavor and supplementing flavor. The issue of smoking and health has received more and more attention from the public, especially smokers. Minimizing the harm caused by smoking is an urgent expectation of the majority of smokers. Therefore, there is an urgent need for a microcapsule technology to encapsulate functional substances to change the shortcomings of the current multi-component composite filter rods.
