[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the application more clear, the technical solutions in the embodiments of the application will be described clearly and completely. The specific conditions not mentioned in the embodiments are carried out according to conventional conditions or the conditions suggested by the manufacturer. The reagents or instruments not mentioned by the manufacturer are conventional products that can be purchased in the market.

[0021] The aerosol content of reconstituted tobacco in heated cigarettes on the market is generally 15%-24%. During the processing, the reconstituted tobacco is prone to severe moisture absorption, resulting in problems such as sticking to the knife and sticking to the thread, thereby reducing the production efficiency. In addition, the aroma release of the product is not uniform, showing a downward trend with each puff. Reducing the moisture absorption rate of the product, stabilizing the uniformity of the aroma release of the product and improving the production efficiency of the product have become technical problems to be solved in the field.

[0022] In a first aspect, the application provides a high-fragrance high-aerosol smoking substrate, wherein the smoking substrate is prepared from non-tobacco materials.

[0023] The smoking base includes the following components in mass parts: 10-20 parts of wood pulp fiber and / or cellulose, 5-10 parts of plant powder, 30-60 parts of atomizing agent, 5-10 parts of adhesive, and 10-30 parts of essence and spice; the bulk density of the smoking base is 1.2-1.8 cm 3 / g, the thickness is 0.12-0.14 mm, and the product basis weight is 90-120 g / m 2 .

[0024] It should be noted that the bulk density is an important indicator for the quality control of the tobacco base sheet, and has an important influence on the permeability, absorbency and quality of the final cigarette product. Increasing the bulk density of the base sheet can not only improve the absorbency of the base sheet to the coating liquid, the smoking performance and the filling value of the cigarette, but also help to realize the light weight of the tobacco sheet, reduce the tobacco consumption, and save the production cost.

[0025] In the optional embodiment of the present application, the wood pulp fiber is selected from at least one of broadleaf wood pulp fiber and / or coniferous wood pulp fiber. Specifically, the wood pulp fiber is selected from at least one of birch wood pulp fiber, poplar wood pulp fiber, linden wood pulp fiber, eucalyptus wood pulp fiber, maple wood pulp fiber, pine wood pulp fiber, larch wood pulp fiber, red pine wood pulp fiber and spruce wood pulp fiber.

[0026] It should be noted that the wood pulp fiber is a non-tobacco material, and is selected as a component of the smoking base based on the characteristics of high strength and strong plasticity of the wood pulp fiber, and the addition of the wood pulp fiber to the smoking base is beneficial to improve the tensile strength performance of the final heated cigarette product.

[0027] In the optional embodiment of the present application, the plant powder is selected from at least one of mint powder, orange peel powder, licorice powder, chrysanthemum powder, sugarcane powder and tea powder.

[0028] It should be noted that the plant powder itself has a certain natural plant aroma, which can further improve the smell of the heated cigarette during combustion or heating. In the optional other embodiments of the present application, the plant powder or tobacco powder can be added or not added according to the characteristic requirements of the actual processed cigarette category, so as to prepare a cigarette product with different characteristic aroma styles.

[0029] In the optional embodiment of the present application, the particle size of the plant powder and the tobacco powder is 80-200 mesh.

[0030] It should be noted that the plant powder and the tobacco powder in this particle size range can be better mixed with the components such as wood pulp fiber, provide sufficient specific surface area to maximize the adsorption of essence and spice, prevent the loss of essence and spice from the cigarette paper, ensure the aroma amount of the heated cigarette product, and maintain the stability of the aroma and taste.

[0031] In an alternative embodiment of the present application, the atomizing agent is selected from at least one of propylene glycol, glycerol, erythritol; further, the atomizing agent has 35-60 parts by mass.

[0032] It should be noted that the amount of smoke of the atomizing agent is positively correlated with its added amount, but the composition of the atomizing agent has strong hygroscopicity, and the moisture absorption rate will increase with the increase of the content of the atomizing agent; if a large amount of atomizing agent is contained in the smoke generating substrate, it is easy to absorb the moisture in the environment with relatively high humidity, and it is easy to appear phenomena such as sticking to the knife and sticking to the filament during the processing of the smoke generating substrate, affecting the normal operation of the production work, and reducing the production efficiency; in addition, it will also affect the quality and quality of the heated cigarette product. Therefore, it is necessary to control the content of the atomizing agent to ensure that it has a relatively low moisture absorption rate.

[0033] The smoke generating substrate has a certain hygroscopicity due to the presence of the atomizing agent, which has a significant impact on the quality, storage and processing process. Specifically, the hygroscopicity of tobacco mainly manifests in moisture absorption. Moisture absorption refers to the ability of the smoke generating substrate to quickly absorb the moisture in the air in an environment with relatively high humidity, increasing its water content.

[0034] The hygroscopicity of the smoke generating substrate has a great influence on its quality and quality: too high humidity will cause the core material to have low strength, increase the processing difficulty, and too high humidity will dilute the components in the tobacco, causing changes in taste and aroma, and reducing the smoke concentration; in addition, too high humidity will also cause the tobacco to have problems such as sticking to the knife and sticking to the filament during processing, reducing production efficiency and increasing production cost; while too low humidity will make the core material dry and brittle, losing its original quality. Therefore, it is necessary to strictly control the amount of atomizing agent added during the preparation of the smoke generating substrate, and the humidity and temperature of the environment need to be strictly controlled during the storage, transportation and processing of the core material, in order to maintain the stability and quality of the tobacco.

[0035] In an alternative embodiment of the present application, the adhesive is selected from at least one of carboxymethyl starch sodium, sodium alginate, guar gum, carboxymethyl cellulose (CMC).

[0036] It should be noted that the adhesive used in the present application has good adhesion and weather resistance, is environmentally friendly and harmless to the human body, and will not affect the taste of the heated cigarette product; it can quickly solidify under heat pressing and has excellent adhesion effect. After heat pressing, the cigarette rod needs to be cut and the filament is shaped, etc. In these processes, the adhesive plays a role in fixing and strengthening the tobacco rod, ensuring the forming quality and taste of the cigarette.

[0037] Specifically, the use of the adhesive can make the components in the smoke generating substrate adhere well together; the prepared smoke generating substrate has high strength and is not easy to fall off; in addition, the prepared heated cigarette product has a certain elasticity, and the smoke concentration and aroma stability are high.

[0038] In an alternative embodiment of the present application, the flavoring agent is selected from at least one of natural flavoring agents and / or synthetic flavoring agents; further, the natural flavoring agent comprises at least one of natural plant extract and / or natural essential oil; further, the synthetic flavoring agent is selected from at least one of vanillin, ethyl vanillin, maltol, ethyl maltol, methylglyoxal, pyrrole, and pyrazine.

[0039] It should be noted that the addition of the flavoring agent can enrich, supplement and correct the aroma of the cigarette product, mask the odor of the cigarette product, and create a novel and unique aroma style. When adding the flavoring agent, the characteristics of the production process, whether the material components interfere with each other, and other factors need to be considered to ensure that the prepared cigarette product can highlight the added flavor style, without masking the inherent tobacco aroma of the cigarette, and in harmony with the tobacco aroma to meet the needs of consumers with different smoking tastes.

[0040] In a second aspect, the present application provides an application of the foregoing smoking substrate, which is used as a tobacco core material alone or in combination with other materials; and the smoking substrate is used to provide high atomization and / or characteristic aroma.

[0041] Further, the smoking substrate is used as a first tobacco core material alone, and is matched with a filter to form a first heated cigarette.

[0042] It should be noted that the first tobacco core material is a non-tobacco smoking substrate, which is matched with a filter to prepare a heated cigarette; and the smoking substrate is processed in a roll shape.

[0043] In an alternative embodiment of the present application, the smoking substrate is arranged in a radial direction in the heated cigarette; specifically, the radial arrangement of the smoking substrate can be an ordered arrangement or an unordered arrangement, and the specific arrangement can be reasonably selected according to actual conditions.

[0044] In an alternative embodiment of the present application, the smoking substrate is combined with a reconstituted tobacco leaf as a second tobacco core material, and is matched with a filter to form a second heated cigarette.

[0045] Further, the reconstituted tobacco leaf is selected from at least one of papermaking core material, thick pulp core material, roller pressing core material, and dry core material.

[0046] It should be noted that the second tobacco core material is a hybrid tobacco core, which is processed in a roll shape. The reconstituted tobacco leaf and the smoking substrate are both independently processed first, which can effectively maintain the aroma stability of the smoking substrate and the simplicity of the processing; and then they are combined and rolled, and the combined tobacco core is cut into shreds to form a hybrid tobacco core, which is matched with a filter to form a heated cigarette.

[0047] The second core material is arranged radially in the prepared heated cigarette; specifically, the smoke-generating matrix is ​​arranged in an orderly manner radially.

[0048] In an optional embodiment of the present invention, the smoking matrix is ​​shredded and mixed with at least one of tobacco shreds, reconstituted tobacco leaves and stems to form a third core material, which is then matched with a filter to produce a third heated cigarette.

[0049] Furthermore, the stems are selected from at least one of traditional stems and expanded stems.

[0050] It should be noted that the third core material is a mixed core material, which is arranged randomly in the radial direction in the prepared heated cigarette.

[0051] In an optional embodiment of the present invention, the length of the shredded smoke-generating matrix is ​​10-25 mm and the width is 0.8-1.2 mm.

[0052] It should be noted that the shredded specifications of the smoking matrix are related to the specifications of the cigarette products being made, the production equipment, etc., and can be reasonably adjusted according to the different lengths of the cigarettes being prepared.

[0053] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0054] Example 1

[0055] This embodiment provides a high-fragrance-loading, high-atomization smoke-generating matrix, the preparation steps of which are as follows:

[0056] S1. Weigh the raw materials of the smoke-generating matrix by mass parts as follows: 10 parts wood pulp fiber, 10 parts sugarcane powder, 45 parts atomizing agent, 15 parts adhesive and 20 parts fragrance and flavoring, and set aside.

[0057] The wood pulp fiber is a mixture of softwood and hardwood pulp (2:1), the atomizing agent is glycerol, the adhesive is CMC, and the fragrance and flavorings are apricot extract, honey extract, fenugreek extract, etc. The sugarcane flour has a particle size of 100-150 mesh.

[0058] S2. Mix and stir the raw materials from step S1 until a thick consistency is formed. Then, shape the mixture using a casting method. Next, process the mixture through drying, slitting, and winding to prepare a high-fragrance-load, high-atomization smoke-generating matrix. The resulting smoke-generating matrix has a bulk thickness of 1.3 cm. 3 / g, thickness is 0.13mm, product basis weight is 100g / m 2 .

[0059] S3. The high-fragrance and high-aerosol generating substrate in step S2 is used as a first tobacco core material alone, and is cut into a rod by a rod-making machine, and is matched with a filter to form a first heated cigarette.

[0061] The high-fragrance and high-aerosol generating substrate provided in the present example is prepared by steps different from those in Example 1 only in that:

[0062] S3. The high-fragrance and high-aerosol generating substrate in step S2 is used as a first tobacco core material alone, and is cut into a rod by a rod-making machine, and is matched with a filter to form a first heated cigarette.

[0063] It should be noted that the content of the aerosol-forming agent in the reconstituted tobacco in the present example is 15%, and the reconstituted tobacco is a core material prepared by a thick pulp method, and other core materials can also be selected according to actual needs. The reconstituted tobacco and the high-fragrance and high-aerosol generating substrate are first prepared into a roll shape, and then the two rolls are placed in the rack of a rod-making machine at a width ratio of 1:1, and the two rolls are stacked together and simultaneously enter a cutting system (see Figure 2 ), and are cut into a tobacco core with a width of 1.0 mm. The mixed tobacco core is cut into a rod by a rod-making machine, and is matched with a filter to form a second heated cigarette. The product is simple to process, has high smoke density, and has obvious characteristics.

[0064] Example 3

[0065] The high-fragrance and high-aerosol generating substrate provided in the present example is prepared by steps different from those in Example 1 only in that:

[0066] S3. The high-fragrance and high-aerosol generating substrate in step S2 is cut into a tobacco core with a width of 1.0 mm and a length of 15 mm, and is mixed with reconstituted tobacco and tobacco shreds to form a third tobacco core material. The third tobacco core material is matched with a filter to form a third heated cigarette.

[0067] It should be noted that the raw materials of the third tobacco core material are as follows: 40 parts of the high-fragrance and high-aerosol generating substrate, 40 parts of reconstituted tobacco, and 20 parts of tobacco shreds, wherein the content of the aerosol-forming agent in the reconstituted tobacco is 15%, and the reconstituted tobacco is a core material prepared by a papermaking method, and other core materials can also be selected according to actual needs. The raw materials of the third tobacco core material are uniformly distributed in the hopper by a distribution trolley, and are balanced for 24 h.

The product has a large number of continuous puffs, and has good stability.

[0068] Comparative Example 1

[0069] The comparative example provides a reconstituted tobacco leaf, the preparation steps of which are as follows:

[0070] S1. The raw materials of the smoke generating substrate are weighed as follows in parts by mass: 10 parts of wood pulp fiber, 40 parts of tobacco powder, 20 parts of atomizing agent, 10 parts of adhesive and 20 parts of essence and spice (containing tobacco extract), for standby use. Among them, the particle size of the tobacco powder is 80-120 mesh.

[0071] S2. The raw materials in step S1 are mixed and stirred uniformly to form a thick substance, and a casting method is used for molding treatment; then the process of drying, slitting and winding is sequentially performed to prepare a reconstituted tobacco leaf substrate for standby use.

[0072] S3. The reconstituted tobacco leaf substrate in step S2 is used as a tobacco core material alone, and is cut into rods by using a rod making machine, and is simultaneously interfaced or compounded with filters to form a reconstituted tobacco leaf heat cigarette.

[0073] Comparative Example 2

[0074] The existing commercially available HEETS product (amber flavor) is used for sensory evaluation by using the IQOS smoking set.

[0075] Test Example 1

[0076] In this test example, the high-essence high-atomization smoke generating substrate prepared in Example 1 and the reconstituted tobacco leaf substrate prepared in Comparative Example 1 are placed in an environment with a relative humidity of 50% RH and a temperature of 24°C, and the moisture absorption rates of the substrates at 20 min, 40 min, 60 min, 90 min and 120 min are measured, respectively. The calculation formula of the moisture absorption rate is as follows:

[0077] Moisture absorption rate = (moisture absorption value - initial moisture absorption value) / initial moisture absorption value x 100%.

[0078] The corresponding test results are shown in Table 1.

[0079] Table 1 Moisture absorption rate data

[0080]

[0081] From the moisture absorption rate results in Table 1, it can be seen that the high-essence high-atomization smoke generating substrate of the present application has a lower moisture absorption rate than the reconstituted tobacco leaf substrate under a higher atomizing agent content, and the moisture absorption rate thereof at 2h is only 2.70%, while the moisture absorption rate of the reconstituted tobacco leaf substrate at 2h is 5.06%, which is 87.4% higher than the moisture absorption rate of the high-essence high-atomization smoke generating substrate at 2h. The lower moisture absorption rate of the high-essence high-atomization smoke generating substrate can effectively avoid the problems of knife sticking and thread sticking in production, and can greatly improve the production efficiency and save the production cost.

[0082] Test Example 2

[0083] In this test example, the first heated cigarette-third heated cigarette prepared in Example 1-3, the reconstituted tobacco leaf heated cigarette prepared in Comparative Example 1, and the HEETS product on the market in Comparative Example 2 were smoked by central heating, and the smoke concentration index, aroma amount, aroma value, aroma lasting puffs, and smoke stability generated during smoking were evaluated by sensory test. The test subjects were teachers of different ages and experienced in the development team, and the number of test persons was 7. The specific test results are shown in Table 2.

[0084] Among them, the test instrument selected for the determination of smoke concentration index is HNB cigarette smoke concentration detector (FH-Y1211), and the related parameters are as follows: each puff capacity: 55ml, puff interval: 15s, smoking rate: 17.5ml / s.

[0085] Table 2 Sensory evaluation results

[0086]

[0087] From the sensory evaluation results in Table 2, it can be seen that the heated cigarette prepared by using the high aroma-carrying and high atomization smoking substrate in Example 1-3 has high smoke concentration index, strong aroma-carrying capacity, long aroma lasting puffs, and high smoke stability.

[0088] In summary, the high aroma-carrying and high atomization smoking substrate provided by the present application is prepared from non-tobacco materials, and the prepared smoking substrate has a low hygroscopicity, effectively avoiding the sticking of knives and filaments during production, which is conducive to improving production efficiency and reducing production cost. The smoke concentration of the product is high, the aroma-carrying capacity is strong, the aroma lasting puffs are long, and the stability is good.

[0089] In the application of the high aroma-carrying and high atomization smoking substrate, it is used alone as a tobacco core material or in combination with other materials as a tobacco core material for preparing a heated cigarette. The development of style and taste products only needs to adjust the aroma of this substrate, and match with a filter, so as to form a heated cigarette with different functions and styles to meet the needs of consumers with different smoking tastes.

[0090] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
