Description

Cigarette product, preparation method and use thereof Technical field

The invention belongs to the technical field of tobacco, and in particular relates to a smoking article, a preparation method thereof and use thereof.

Background technique

The suction-heated non-combustible tobacco product includes tobacco cut tobacco, tobacco chips, tobacco particles, smoke, and the like as compared to conventional cigarettes. However, when the non-combustion type heating tobacco product is heated, the temperature of the tobacco portion is low, and only the tobacco is heated without burning the tobacco, so that the generation of tar can be greatly reduced or even avoided. When the consumer sucks and heats the non-combustion type of tobacco product, no flue gas is generated, and smoke that enters the environment is hardly generated, so-called "second-hand smoke", which greatly reduces environmental pollution. Heating non-combustible tobacco products is being welcomed by some tobacco consumers because of its extremely low tar content and environmental friendliness, and is gradually being accepted by cigarette consumers in most countries.

Existing heated non-combustible tobacco products are mainly in the form of filaments, granules or powders. For example, ploom's heating non-burning smoking products are powder or granules, using aluminum can heating (Public No. 101951796A); Philip Morris Production Company's company's silk-like smoking products (Public No. 103841844A); Tobacco Particles of Tobacco LLC (Publication No. 102325472A). These forms of heating tobacco products are not of an integrated construction and are therefore disadvantageous for being placed and removed from the heating non-combustion device. In addition, these forms of heating tobacco products are prone to generate powders and granules after heating, causing contamination of the heating chamber of the non-combustion device, and even some fine dust is generated, which is disadvantageous for keeping the cavity clean.

Preferably, the fragrance is selected from one or more of the edible natural flavor, the edible synthetic flavor, the natural flavor for tobacco, and the synthetic flavor for tobacco. The edible natural flavor is selected from the group consisting of lemon oil, vanilla bean curd, Asian peppermint oil, cocoa butter, and geranium oil. The edible synthetic fragrance is selected from the group consisting of vanillin, citral, menthol, ethyl butyrate, and linalool. The natural flavor for tobacco is selected from the group consisting of clove bud oil, apple juice, Lai Baidang oil, fenugreek extract, and Peruvian balm. The synthetic flavor for tobacco is selected from one of 2-acetylpyrazine, ethyl acetate, furanone, eugenol, and ethyl maltol.

More preferably, in the raw material component of the smoking article of the present invention, the mass ratio of bentonite, diatomaceous earth, flue-cured tobacco, glycerin, water, flavor is (400-500): (300-400): (200~ 300): (600 ~ 800): (100 ~ 200): (10 ~ 30);

Or, the mass ratio of kaolin, zeolite, oriental tobacco, glycerin, water, and flavor is (500 to 600): (200 to 300): (200 to 300): (700 to 900): (100 to 200): (10~30);

Or, the mass ratio of clay, silica, flue-cured tobacco, glycerin, water, and flavor is (500-600): (200-400): (200-300): (700-900): (100-200) : (10 ~ 30).

Preferably, the mixing order of each raw material component is: first mixing the atomizing agent, water and flavor to obtain a mixed solution; then mixing the inorganic binder, the inorganic adsorbing material and the tobacco uniformly to obtain a mixed dry material; finally mixing A mixed solution is added to the dry material.

Preferably, the extrusion molding is performed by a screw extruder, and the cross-sectional shape and cross-sectional area of the extruded smoking article are determined by a template matched with the extruder, and different templates can be selected as needed. After extrusion molding, the smoking article can be cut to a certain size, preferably, the cutting length is 10 to 16 mm.

Since the temperature and time of the drying treatment affect the suction quality of the integrated smoking article, in the present invention, preferably, the drying treatment temperature is 100 to 150 ° C and the time is 10 min to 180 min. More preferably, the drying treatment is carried out at a temperature of from 105 to 130 ° C for a period of from 0.5 h to 1.5 h.

A third aspect of the invention also provides the use of the smoking article described above for heating a non-burning cigarette.

When the smoking article of the present invention is applied to heating non-combustion cigarettes, the integrated smoking article is placed in a heating non-combustion device, heated to 150-400 ° C and then suctioned. The smoking article of the invention does not burn at the above heating temperature, and can enable the user to obtain a good suction feeling. When the temperature reaches 150 ° C, the smoke can be generated, and when the temperature exceeds 400 ° C, the harmful substances generated by the thermal cracking are large. Increase is not conducive to the health of consumers.

The smoking article of the invention is provided with an inorganic binder, so that the smoking article is integrally formed, and has sufficient bending strength, so that the consumer can easily put in or take out the smoking article from the heating non-combustion device; The binder does not produce a taste under heating to 150 to 400 ° C and does not affect the flavor of tobacco and flavor. The addition of water can make the bonding effect of the inorganic binder better, not only to effectively bond the inorganic binder, but also to prevent the surface of the smoking article from being too moist. The inorganic adsorbing material added by the invention can adsorb the atomizing agent and moisture, improve the liquid adsorption amount of the smoking article, and does not generate odor at 150-400 ° C, and does not affect the flavor of tobacco and flavor, thereby ensuring Obtain sufficient smoke and tobacco aroma at 150-400 °C. Through the addition of the inorganic binder and the inorganic adsorbing material, it is convenient to control the proportion of the tobacco, so that the nicotine and the tobacco flavor are effectively regulated.

The smoking article prepared by the invention is an integrated structure after extrusion molding, and is applied to heating non-burning tobacco products, convenient to put in and take out the heating non-combustion device, and does not generate powder and particles, and is convenient for cleaning. In addition, since the inorganic binder is added, the strength of the integrated smoking article can be improved, and the intrinsic aroma of the tobacco can be prevented from being affected by the bad odor of the external bonding agent. At the same time, since the inorganic adsorbing material can adsorb a large amount of the atomizing agent and the fragrance, a large amount of smoke and aroma substances can be generated to enhance the suction feeling of the consumer. The smoking article of the invention has high strength, is not easy to be damaged in structure, can accurately control the tobacco content, and extracts aroma substances in the tobacco raw material by heat to release nicotine. The method for preparing the integrated smoking article of the invention has simple molding process and is different from the traditional silk making process.
