High-porosity tobacco sheet which has mint fragrance and is applied to low-temperature cigarette and production process

Abstract

The invention provides a high-porosity tobacco sheet which has a mint fragrance and is applied to a low-temperature cigarette and a production process. The tobacco sheet is prepared from, by mass, 50-80% of tobacco raw material powder, 10-30% of atomizing agent, 0.5-10% of binding agent, 0.01-1% of swelling agent, 2-15% of mint leaf powder and 0-30% of water. The tobacco sheet is prepared by meansof a production process of a roller-press method. The production process is not changed during preparation of the sheet, and the swelling agent is added into a formula of raw materials in order to make the sheet swell and provide convenience for greatly absorbing the atomizing agent and additional fragrance. By using the mint leaf powder for replacing additional essence, consumers can smell a pleasant fresh fragrance like mint during smoking, and the obtained smoke amount and physical satisfaction are more abundant and more similar to those of traditional cigarettes. Meanwhile, the productionprocess of the sheet is mature and simple, high in controllability and stable in quality.

Description

technical field [0001] The invention relates to the technical field of novel tobacco products, in particular to a tobacco sheet with mint flavor and high porosity applied to low-temperature cigarettes and a production process thereof. Background technique [0002] Low-temperature cigarettes, also known as heat-not-burn cigarettes, heat the tobacco substance through an external heat source, and the atomization medium, flavor components and added flavors in the tobacco substance are heated to produce a smoke similar to that of traditional cigarettes. Smoke, so that consumers get physiological satisfaction. Tobacco substances in low-temperature cigarettes are only heated but not burned, and the heating temperature (250°C-350°C) is much lower than the combustion temperature (800°C-900°C) of traditional cigarettes. Therefore, the harmful components and biological toxicity of smoke are greatly reduced. Sidestream smoke and ambient smoke are also significantly reduced. [0003] L...

AI Technical Summary

Problems solved by technology

[0004] However, at present, when consumers smoke low-temperature cigarettes, whether it is peripheral heating or inner core heating, compared with traditional cigarette smoking, there are problems of insufficient physiological satisfaction and insufficient smoke volume.

This is because on the one hand, the tobacco section of low-temperature cigarettes generally does not exceed 0.2 grams (about 0.7 grams in traditional cigarettes), and the tobacco aroma components, atomized media and added flavors contained in it are limited. On the other hand, when heated by an external heat source, the thermal conductivity of the tobacco substance itself is poor, and the temperature of the tobacco substance close to the heat source is relatively high, and the atomization medium, flavor components and added aroma contained in the tobacco substance can Better atomization and volatilization, while the temperature of the tobacco material far away from the heat source is low, and the atomization medium, flavor components and added flavor contained in the tobacco material cannot be effectively atomized and volatilized

[0005] At present, the tobacco section of low-temperature cigarettes generally uses rolled-pressed tobacco sheet. If a large amount of atomization medium and flavoring are directly added to the tobacco powder, it will affect the forming of the rolled-pressed tobacco sheet.
