A combustible heating cigarette with controllable combustion rate

PendingCN122074706ACigar manufactureCigarette useMechanical engineering
This invention provides a combustion-type heated cigarette with adjustable combustion rate. The heated cigarette includes a combustion section, a core section, and a filter section coaxially connected in sequence. The combustion section, core section, and filter section are formed by wrapping the combustion section with cigarette paper. The cigarette paper wrapping the combustion section is a cigarette paper with adjustable combustion rate, and the cigarette paper with adjustable combustion rate is a cigarette paper coated with inorganic powder. Under the condition of the same combustion section length, the heated cigarette of this invention, by wrapping the combustion section with specific cigarette paper, significantly extends the combustion time compared to conventional combustion-type heated cigarettes using ordinary cigarette paper, ensuring sufficient and sustained total heat output. The degree of pyrolysis of the tobacco material in the core section is significantly improved, and the smoke release is more complete and stable.

Method for improving smoking stability of heated cigarette by using internal and external coupling heating method

This invention relates to a method for improving the smoking stability of heated cigarettes using an internal and external coupling heating method, belonging to the field of heated cigarette technology. The method includes the following steps: heating the cigarette core using an internal and external coupling heating method. Initially, internal heating is the primary method. When the temperature of the heat source used for internal heating reaches the operating temperature, the temperature of the heat source used for internal heating and / or the temperature of the heat source used for external heating is adjusted to ensure that the volume of the portion of the cigarette core with a temperature greater than T / n increases uniformly. This method, by employing an internal and external coupling heating method and adjusting the temperature of the heat source used for internal heating and / or the temperature of the heat source used for external heating to achieve matching coupling of internal and external heating, aims to achieve a "slow release" of tobacco components in the cigarette core material, significantly improving the puff-by-puff release stability of the heated cigarette.

PendingCN122074697ATobacco preparationTobacco treatmentCigarette usePyrazine
This invention discloses a tobacco pyrolysis refined product, its preparation method, and its application. The pyrolysis refined product is obtained by pyrolysis of tobacco raw materials to obtain pyrolyzed tobacco material; the pyrolyzed tobacco material is mixed evenly with a solvent and homogenized, then separated into solid and liquid components, and the supernatant is collected to obtain a pyrolyzed tobacco material extract; the extract is then subjected to molecular distillation, and the light component fraction is collected to obtain the final product. Based on the synergistic effect between its components, this refined product significantly increases the content and variety of aroma compounds, especially pyrazines, pyridines, and nicotines. When used as a flavoring agent in heated cigarettes, it effectively improves the sensory quality of heated cigarettes. Heated cigarettes using this refined product have a rich and mellow aroma, high richness, significantly increased smoke concentration, a more comfortable strength, a more delicate and mellow smoke, a significantly improved aftertaste, and a greatly improved consistency in aroma and smoke.

Tobacco rod stem removal control method and device, electronic equipment and storage medium

PendingCN122350372ABiotechnologyCigarette use
This invention discloses a method, device, electronic device, and storage medium for controlling stem and twig removal in a cigarette-making machine. The method includes: determining a first prediction model, which characterizes the quantitative relationship between multiple first parameters and the amount of stem and twig removal during the production of a first cigarette using a cigarette-making machine. The multiple first parameters are multiple process parameters of the cigarette-making machine, used to control the amount of stem and twig removal. Based on a first condition, the method determines multiple first values ​​using the first prediction model. The first condition indicates that the amount of stem and twig removal during the production of a first cigarette using the cigarette-making machine is greater than a first preset threshold. The multiple first values ​​include the values ​​corresponding to the multiple first parameters when the first condition is met. The method then controls the stem and twig removal during the production of a first cigarette using the cigarette-making machine based on the multiple first values. This solution enables precise control of stem and twig removal during the production of a first cigarette using a cigarette-making machine.
