Problems solved by technology

Although some China Tobacco companies and scientific research institutions in China are interested in the research of such products, most of them focus on the two aspects of basic theory and equipment research and development, or they are still in the laboratory research stage, and have not yet formed relatively mature products. Research smoking sets and a large number of patents
However, there is no report on the development of heat-not-burn cigarette core materials and their preparation methods based on dry reconstituted tobacco leaves.

preparation example Construction

[0051] The present invention also provides a method for preparing a heat-not-burn cigarette core material. The heat-not-burn cigarette core material is the above-mentioned heat-not-burn cigarette core material. The preparation method includes:

[0052] Pulverizing and sieving the tobacco raw material to obtain smoke powder;

[0053] The plant fiber is formed into several single fibers through anhydrous fibrillation, and then formed into a base sheet through an airflow former;

[0054] mixing the smoke powder, the fuming agent, the auxiliary material and water to obtain a coating liquid;

[0055] The coating liquid is sprayed and dried on the substrate.

[0056] Preferably, the particle size of the smoke powder is 40-400 mesh, such as 40 mesh, 80 mesh, 100 mesh, 150 mesh, 200 mesh, 250 mesh, 300 mesh, 350 mesh or 400 mesh.

[0057] Preferably, the length of the single fiber is 0.5-3.0 mm, such as 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm or 3.0 mm.

[0058] Preferably, the quan...

Embodiment 1

[0063] A heat-not-burn cigarette core material, comprising the following raw materials in parts by weight: 10 parts of unbleached wood pulp fiber, 49 parts of flue-cured tobacco leaf monomer (Yunyan 85), 40 parts of glycerin and 1 part of ethyl cellulose.

[0064] The preparation method of the heat-not-burn cigarette core material comprises the following steps:

[0065] (1) Preparation of tobacco powder: take the flue-cured tobacco leaf monomer with moisture control below 10%, pass through a 40-mesh sieve after being pulverized by a pulverizer, and set aside;

[0066] (2) Preparation of the coating solution: mix the prepared tobacco powder with glycerin, guar gum and an appropriate amount of water evenly to form a coating solution with a solid content of 25%, and set aside;

[0067] (3) Preparation of the base sheet: After defibrating the unbleached wood pulp fibers into several single fibers with a length of 0.5 mm, the base sheet is formed into a base sheet by combining natu...

Abstract

The invention discloses a cigarette core material free of burning during heating and a preparation method thereof. The cigarette core material comprises, by weight, 5-30 parts of plant fiber, 40-85 parts of tobacco raw material, 5-40 parts of smoke agent, 0-20 parts of tobacco flavor and 1-10 parts of auxiliary material. The cigarette core material is formed through dry-process airflow forming technology, thereby having high loading performance; high-proportion adding of the smoke agent is realized; high reducibility and porous physical structure of tobacco active ingredients that dry-process reconstituted tobacco leaves have are combined, so that efficient smoking of formed cigarettes free of burning during heating can be guaranteed, high-level sensory quality of formed cigarette products free of burning during heating and effective volatilization of formed smoke can be guaranteed, and the cigarette products are enabled to have good sensory quality and user experience.

Description

technical field [0001] The invention relates to the technical field of heat-not-burn cigarettes, in particular to a heat-not-burn cigarette core material and a preparation method thereof. Background technique [0002] Against the background of increasingly severe tobacco control environment, the sales of traditional tobacco products have stagnated or even declined in some developed countries, which makes the research of new tobacco products urgent. As an important part of new tobacco products, heat-not-burn cigarette products are smoked by baking instead of lighting. Compared with traditional cigarettes, the heating temperature of heat-not-burn tobacco products is much lower than the combustion temperature, which can effectively reduce the harmful components produced by high-temperature combustion and cracking of tobacco, and greatly reduce the tar and harmful components produced by combustion. At the same time, unlike the smoldering way of conventional cigarettes, the shre...
