Abstract
The invention relates to a preparation method of a smoking material for heating cigarettes and the heating cigarettes, which comprises the steps of beating a fiber raw material into fiber pulp, uniformly mixing the fiber pulp with tobacco powder, a pore-forming agent and a bonding agent, forming into a fixed shape, changing conditions, forming pores, and drying to obtain the smoking material for heating the cigarettes. The preparation process of the smoking material is simple, and when the smoking material is applied to smoking, smoke can smoothly circulate in the smoking material; meanwhile, smoke generated by heat of tobacco powder of the solid part of the smoking material can be smoothly sucked into the inlet, so that the smoking mist quantity is sufficiently increased, and the utilization rate of the smoking material is improved; in addition, the smoking material can be made into various three-dimensional shapes according to the requirements, is convenient to carry, is very convenient to disassemble, assemble and replace, is convenient to use and is beneficial to the smoking material.
Description
Technical Field
The invention relates to a preparation method of a smoking material for heating cigarettes and the heating cigarettes, and belongs to the technical field of heating tobacco products.
Background
With the increasing public health awareness, smoking and health problems become the most important issues for the tobacco groups in the world. The heated cigarette (also called as low-temperature cigarette and non-burning cigarette) is a mainstream product in the market quickly by virtue of the characteristics that the smoking feeling of the heated cigarette is close to that of the traditional cigarette and the harmful ingredients are lower than those of the traditional cigarette. In order to meet the market demand, a great amount of manpower, material resources and financial resources are successively input into the field of heating tobacco products by various tobacco companies at home and abroad, so that a place is obtained for the demand.
In recent years, domestic and foreign heated cigarette products are on the market successively. Overseas, the research on heating cigarettes by various international tobacco huge heads is early, and the market share of related products is also large, such as IQOS of fimo international, Revo of Reynolds corporation, tobacco Glo in English and American, and tobacco Ploom in Japan. Wherein, the iQOS of Feimo international obtains the PMTA certification of FDA in 2019, becomes the first product passing the PMTA certification, and further proves that the heated cigarette is less harmful compared with the traditional tobacco. IQOS is now marketed in over 50 countries worldwide, and about 1060 ten thousand smokers have completely replaced the traditional cigarette by using IQOS, which is not well-behaved in development for a while. In China, although the development in the field of heating cigarettes is late, related products such as 'Kung kung fu' of cigarette in Sichuan, 'MC' of cigarette in Yunnan, 'MU +' and 'ING' of cigarette in Guangdong, 'UGare' of cigarette in Jiangsu, and 'HEO' of cigarette in Hunan are put on the market after years of effort.
The vast majority of smoking materials for the above marketed heated cigarette products are of the cut tobacco, flake and pellet types. The preparation method is mainly improved on the preparation process of the traditional tobacco shreds and reconstituted tobacco, and is characterized in that the smoking experience is close to that of the traditional cigarette, but the preparation process is complex and the material load rate is lower; the granular smoking material is represented by 'UGare' of Japanese tobacco Ploom and Jiangsu Zhongyan, and the preparation method of the granular smoking material is mainly improved on the medicine granule process, and the granular smoking material is characterized by high material loading rate, simple manufacturing process, poor smoking feeling compared with tobacco shreds and slice smoking materials, and complicated use.
Chinese patent specification CN201911000829.0 discloses a heat non-combustible tobacco product comprising a solid tobacco rod, the filter, transition and solid tobacco rod segments of the product are described, but the method of making the solid tobacco rod is not involved. Chinese patent specification CN201911000875.0 discloses a heated non-combustible smoking article comprising a solid cellular tobacco material, the structure and function of which is described, and the preparation of the solid cellular tobacco material only refers to the foaming process, but does not refer to the specific manufacturing method.
Disclosure of Invention
In view of the shortcomings of the prior art, one of the objectives of the present invention is to provide a method for preparing a smoking material for heating cigarettes, so as to prepare a smoking material with a rich pore structure; the second purpose of the invention is to provide a heated cigarette.
The technical scheme adopted by the invention is as follows:
a method of making a smoking material for heating a cigarette, comprising the steps of:
s1, mixing the fiber raw material with water, pulping to obtain fiber pulp;
wherein the content of the fibers in the fiber slurry is 6-95 wt%;
s2, uniformly mixing the tobacco powder, the pore-forming agent, the adhesive and the fiber slurry obtained in the S1 to obtain a mixture;
wherein the mass ratio of the tobacco powder to the fiber pulp is 1:1-6, further 1:1-4, and the addition amount of the adhesive is 0.5-15wt%, further 1-12 wt%, further 2-11.5 wt%, preferably 2-5 wt% of the fiber pulp;
s3, forming the mixture obtained in the S2 to obtain a rough blank;
and S4, carrying out pore-forming treatment on the rough blank obtained in the S3, and drying to obtain a finished smoking material.
