DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0028] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] When amount, concentration or other value or parameter is represented by range, preferred range or a series of upper preferred value and lower preferred value, this should be understood as specifically disclosing all ranges formed by any pairing of any range upper limit or preferred value and any range lower limit or preferred value, regardless of whether the range is disclosed separately. For example, when disclosing range "1-5", described range should be interpreted as including range "1-4", "1-3", "1-2", "1-2 and 4-5", "1-3 and 5" etc. When numerical range is described in this article, unless otherwise stated, the range is intended to include its end value and all integers and fractions within the range.

[0032] "Parts by mass" refers to the basic unit of measurement for expressing the mass ratio of multiple components. 1 part can represent any unit mass, such as 1g or 2.689g. If we say that the mass of component A is a parts and the mass of component B is b parts, it means the ratio of the mass of component A to the mass of component B is a:b. Alternatively, it means that the mass of component A is aK and the mass of component B is bK (K is an arbitrary number, indicating a multiple factor). It should not be misunderstood that, unlike the mass parts, the sum of the mass of all components is not limited to 100 parts.

[0033] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other in a variety of ways.

[0034] Example 1

[0035] refer to Figures 1 to 3 As shown, an embodiment of the present application provides a heat-not-burn tobacco core material production line 100, which is used to produce heat-not-burn tobacco core materials. The tobacco core material production line includes a pretreatment mechanism 110, a slurry mixing mechanism 120, a molding mechanism 130, a drying mechanism 140 and a processing mechanism 150.

[0036] Combination Figure 1As shown, specifically, the slurry mixing mechanism 120 is used to mix the thick slurry product, the pretreatment mechanism 110 extends to the slurry mixing mechanism 120, and the pretreatment mechanism 110 is used to pretreatment the material; the forming mechanism 130 includes a transmission unit 131, a thickness control unit 132 and a flow unit 133, the slurry mixing mechanism 120 extends to the flow unit 133, the flow unit 133 is connected to the transmission unit 131, and the thickness control unit 132 is connected to the flow unit 133, so that the thickness control unit 132 can control the thickness of the thick slurry product, and the flow unit 133 includes a first flow unit 1331 and a second flow unit 1332 to process thick slurry products in different states, and the thick slurry products in different states may include a thick slurry product in a first preset state (low concentration and low viscosity) and a thick slurry product in a second preset state (high concentration and high viscosity). The drying mechanism 140 includes an oven unit 141, and the transmission unit 131 extends to the oven unit 141; the processing mechanism 150 is connected to the end of the oven unit 141 away from the molding mechanism 130, and is used to process the product. The process of the production line is improved, and a continuous production method is adopted to improve production efficiency and high energy utilization.

[0038] Combination Figure 4 and Figure 5As shown, in one embodiment, specifically, the first flow unit 1331 includes a slurry collector 1331a and a liquid collector 1331b. The slurry collector 1331a is arranged at one end of the transmission unit 131 away from the oven unit 141. The slurry collector 1331a can be a single-port or multi-port slurry box with adjustable flow rate. The liquid collector 1331b is connected to the slurry collector 1331a, so that the first flow unit 1331 processes a thick slurry product in a first preset state. The thick slurry product in the first preset state is a thick slurry product in a low concentration and low viscosity state. Exemplarily, the viscosity of the thick slurry product in the first preset state is η, satisfying η≤2000mPa.s. The viscosity of the thick slurry product can be 1500mPa.s, 1600mPa.s, 1700mPa.s, 1800mPa.s, 1900mPa.s, or 2000mPa.s. Therefore, the thick slurry product in the first preset state has a larger water content and a higher fluidity. It can be understood that the liquid collector 1331b is arranged at the transmission rear end of the slurry flower 1331a relative to the transmission unit 131. When the slurry flower 1331a transmits the thick slurry through the transmission unit 131, the excess liquid is collected to achieve recycling and reuse, while ensuring the transmission efficiency of the thick slurry product.

[0039] refer to Figure 3 and Figure 4 As shown, in one embodiment, optionally, the second flow unit 1332 includes a coater 1332a, which processes a thick slurry product in a second preset state. The thick slurry product in the second preset state is a thick slurry product in a high concentration and high viscosity state. Exemplarily, the viscosity of the thick slurry product in the second preset state is η, satisfying 3200mPa.s≤η≤4200mPa.s. The viscosity of the thick slurry product can be 3200mPa.s, 3500mPa.s, 3600mPa.s, 3800mPa.s, 4000mPa.s, 4200mPa.s and any value between 3200mPa.s-4200mPa.s. It can be understood that the coater 1332a can ensure stable discharge and can adjust the discharge amount. Alternatively, the second flow unit 1332 can be a single-port pump, which controls the thickness of the thick slurry product through the thickness control unit 132, so that the second flow unit 1332 can process the thick slurry product in a second preset state.

[0040] Combination Figure 4 As shown, in one embodiment, optionally, the thickness control unit 132 includes a first thickness control member 1321 and a second thickness control member 1322, the first thickness control member 1321 is adjustably arranged on the transmission unit 131, and the second thickness control member 1322 is arranged perpendicular to the transmission unit 131, that is, the setting direction of the second thickness control member 1322 is perpendicular to the transmission direction of the transmission unit 131, so as to keep the thickness of the thick slurry product on the transmission unit 131 stable and consistent.

[0041] In one embodiment, specifically, the transmission unit 131 includes a conveyor belt and a supporting member, the supporting member is arranged on the conveyor belt, and the supporting member is a mesh structure. Accordingly, the supporting member with a mesh structure can be used to support the thick slurry product, and the thick slurry product can be coated more conveniently to maintain its uniformity. Optionally, the material of the supporting member is a combination of one or more of non-woven fabrics, woven fabrics, woven fabrics and knitted fabrics. Compared with the use of steel belts, the use of the above-mentioned supporting member materials can reduce production and operation costs, and the maintenance, replacement and cleaning of the supporting member are also more convenient. In the subsequent drying process, it is convenient to use hot air instead of steam direct heating for drying, so that the product is heated more evenly, further reducing energy consumption and improving energy utilization efficiency. Further, optionally, a cleaning device is provided to clean and clear the supporting member with a mesh structure.

[0042] refer to Figure 3 As shown, in one embodiment, specifically, the drying mechanism 140 further includes a monitoring unit 142 , which is disposed in the oven unit 141 , and the monitoring unit 142 can monitor parameter performance of the product in the oven unit 141 .

[0043] Combination Figure 2 As shown, specifically, the slurry preparation mechanism 120 includes a second mixing unit 121, a multi-stage homogenization unit 122 and a defoaming unit 123. One end of the multi-stage homogenization unit 122 is connected to the second mixing unit 121, and the other end of the multi-stage homogenization unit 122 is connected to the defoaming unit 123. The second mixing unit 121 fully mixes the solid and liquid materials, and then performs multi-stage homogenization treatment through the multi-stage homogenization unit 122. It can be understood that the first mixed liquid is subjected to a primary homogenization treatment, then a secondary homogenization treatment, ..., and finally a multi-stage homogenization treatment. Through the multi-stage homogenization treatment, the slurry has better dispersion uniformity during the preparation process, and the viscosity of the thick slurry product is improved. The defoaming unit 123 defoams the product.

[0044] In this embodiment, the heat-not-burn cigarette core material production line 100 improves the process of the production line, adopts a continuous production method to improve production efficiency, and has a high energy utilization rate. A flow unit 133 is set to be able to process thick slurry products in different states, and different molding processes are adopted according to differences in indicators such as the concentration and viscosity of the thick slurry products.

After being processed by the crushing unit, it is transferred to the first mixing unit for uniform mixing, and the uniformity is maintained at about 2% (ash content) during the uniform mixing.

[0049] Combination Figure 4 and Figure 5As shown, in one embodiment, optionally, the first flow unit 1331 includes a pulper 1331a and a liquid collector 1331b. The pulper 1331a is arranged at one end of the transmission unit 131 away from the oven unit 141. The pulper 1331a can be a single-port or multi-port pulper box with adjustable flow rate. The liquid collector 1331b is connected to the pulper 1331a so that the first flow unit 1331 processes a thick slurry product in a first preset state. The thick slurry product in the first preset state is a thick slurry product in a low concentration and low viscosity state. Therefore, the thick slurry product in the first preset state has a large water content and a high fluidity. It can be understood that the liquid collector 1331b is arranged at the transmission rear end of the pulper 1331a relative to the transmission unit 131. When the pulper 1331a transmits the thick slurry through the transmission unit 131, the excess liquid is collected to achieve recycling and reuse, while ensuring the transmission efficiency of the thick slurry product.

[0050] refer to Figure 3 and Figure 4 As shown, in one embodiment, optionally, the second flow unit 1332 includes a coater 1332a, and the coater 1332a processes a thick slurry product in a second preset state.

Alternatively, the second flow unit 1332 can be a single-port pump, which controls the thickness of the thick slurry product through the thickness control unit 132, so that the second flow unit 1332 processes the thick slurry product in the second preset state.

[0051] Combination Figure 4 As shown, in one embodiment, optionally, the thickness control unit 132 includes a first thickness control member 1321 and a second thickness control member 1322, the first thickness control member 1321 is adjustably arranged on the transmission unit 131, and the second thickness control member 1322 is arranged perpendicular to the transmission unit 131, that is, the setting direction of the second thickness control member 1322 is perpendicular to the transmission direction of the transmission unit 131, and accordingly, the first thickness control member 1321 can be an inclined scraper, which can apply the thick slurry product on the transmission unit 131 to keep the thickness of the thick slurry product on the transmission unit 131 stable and consistent, so as to facilitate the subsequent process of molding and drying the product.

[0052] In one embodiment, specifically, the transmission unit 131 includes a conveyor belt and a supporting member, the supporting member is arranged on the conveyor belt, and the supporting member is a mesh structure. Accordingly, the supporting member with a mesh structure can be used to support the thick slurry product, and the thick slurry product can be coated more conveniently to maintain its uniformity. Optionally, the material of the supporting member is a combination of one or more of non-woven fabrics, woven fabrics, woven fabrics and knitted fabrics. Compared with the use of steel belts, the use of the above-mentioned supporting member materials can reduce production and operation costs, and the maintenance, replacement and cleaning of the supporting member are also more convenient. In the subsequent drying process, it is convenient to use hot air instead of steam direct heating for drying, so that the product is heated more evenly, further reducing energy consumption and improving energy utilization efficiency. Further, optionally, a cleaning unit 143 is provided to clean and clear the supporting member with a mesh structure.

[0053] refer to Figure 3 As shown, in one embodiment, specifically, the drying mechanism 140 also includes a monitoring unit 142, and the monitoring unit 142 is arranged in the oven unit 141. The monitoring unit 142 can monitor the parameter performance of the product in the oven unit 141, and the monitoring indicators include but are not limited to indicators such as moisture content and temperature. Optionally, the oven unit 141 can make a tunnel-type drying box group, which is composed of multiple drying boxes connected in series, so as to facilitate better drying of the products on the production line and improve the drying effect.

The secondary drying unit can be operated by cold air drying, using low-temperature and low-humidity cold air to circulate around the product to gradually reduce the content of the product to achieve a drying effect. Optionally, cold air drying and / or infrared drying and / or microwave drying can be used together or separately for drying treatment to improve the drying effect. After drying in the secondary drying unit, the trimming unit, calendering unit, product scanning unit and winding unit are used to process the product to obtain a cigarette core material product.

It should be noted that the above production schemes all use the same product raw materials and product formula, and the results are shown in Table 1 below:

[0060]

[0061]

[0062] It can be seen from Table 1 above that, compared with the comparative example, the production lines of Examples 1 and 2 are capable of processing thick slurry products in different states by setting the flow unit 133. The parameter indicators of Examples 1 and 2 are relatively close. The concentration and viscosity of the products produced during the production process are higher, so that the final cigarette core material product quality is better, with good processing resistance and quality stability. At the same time, the steam consumption per ton of product of the entire production line is reduced by about 50% compared with the comparative example. The process of the production line is improved, and a continuous production method is adopted to improve production efficiency, and the energy utilization rate is high.

[0065] Example 5

[0066] The embodiment of the present invention further provides a cigarette, which is made of the cigarette core material in Example 4.

[0067] In one embodiment, specifically, the cigarette comprises a cigarette core segment, a hollow support segment, a cooling segment and a filtering segment adjacent to each other in sequence;

[0068] The core material is arranged in the core section.

[0069] The core section is the tobacco material that provides heating volatiles, the hollow support section is to isolate the core section and the cooling section. The purpose of the cooling section is to cool down the high-temperature volatiles to avoid excessively high smoking temperatures, and the filtering section is to filter larger particles to reduce harm.
