Description

Charcoal heated smoking article and preparation method thereof

Technical field

The invention belongs to the technical field of tobacco products, and in particular relates to a charcoal-heated smoking product and a preparation method thereof.

Background technique

There are currently carbon-heated smoking products on the market, which mainly heat the air through the combustion of carbon materials. When smoking, the hot air passes through the tobacco material containing atomizer, and the heated tobacco material promotes the release of nicotine, atomizer and flavor. After the ingredients escape, the escaping material passes through a cooling section and enters the consumer's mouth.

In actual use, after the charcoal material is ignited, the smoke in the first five puffs has a large amount of atomization and a pure smell. However, when taking the sixth puff, the smoke in the charcoal-heated smoking product has an obvious burnt smell. The axial temperature measurement of the carbon-heated smoking product (Eclipse) found that at the moment of puffing, the maximum temperature of the tobacco material at a distance of 2 mm from the carbon material is as high as 550°C, and the maximum temperature of the tobacco material at a distance of 4 mm from the carbon material is as high as 650°C. The smoke test showed that the tar content of the charcoal-heated smoking product (Eclipse) after 11 puffs was 4.57 mg/cigarette. It is the excessively high temperature at the tobacco material that causes partial decomposition of the tobacco material.

The temperature of the tobacco material immediately adjacent to the carbon material is relatively high. In order to effectively reduce the temperature of the smoke reaching the human mouth, the tobacco material segments of the charcoal-heated smoking product (Eclipse) are arranged in a directional manner, with the overall length reaching 21mm (0.3g of tobacco material). ). In carbon-heated smoking products (Eclipse), the tobacco material adjacent to the carbon material is distributed in a directional arrangement, which increases the strength requirements of the tobacco material and makes the production process of the tobacco material segment more complicated. In addition, the longer tobacco material length (0.3g tobacco material) adjacent to the carbon material also increases the amount of tobacco material, which undoubtedly increases the cost of the carbon-heated smoking article (Eclipse). Furthermore, the cooling section of the existing charcoal-heated smoking product (Eclipse) uses 0.4g of tobacco material, which also increases the cost accordingly.

Therefore, how to provide a charcoal-heated smoking product and a preparation method thereof to solve the problem in the prior art that in order to reduce the temperature of the smoke reaching the human mouth, the tobacco material segments adjacent to the carbon material in the charcoal-heated smoking product (Eclipse) are directionally arranged. , the method of increasing the overall length leads to an increase in the strength requirements of the tobacco material, and makes the generation process of charcoal-heated smoking products more complicated.
