Description

Technical Field

[0001] This invention relates to the field of heated non-combustible tobacco product manufacturing technology, and in particular to a method for reducing the amount of atomizing agent applied to heated cigarettes. Background Technology

[0002] Heated cigarettes, as a new category of cigarettes, are closest to traditional cigarettes in terms of smoking method, physiological and psychological perception, and have advantages such as low tar production and less release of harmful components. Heated cigarettes primarily use a heat source below 350℃ to heat tobacco materials (shredded tobacco, sheets), causing the effective components in the tobacco material to volatilize. To ensure the full release of nicotine from the tobacco material, the main method is to add a large amount of glycerol, propylene glycol, or their derivatives or polymers to the tobacco material. Since a significant amount of glycerol, propylene glycol, or their derivatives or polymers are lost during sheet processing (generally more than 30% by sheet weight), the content of the atomizing agent in the dried sheet is (8-12)% (by sheet weight), which promotes the effective release of nicotine and aroma-producing substances in the tobacco material, thereby providing smokers with a similar sense of pleasure and satisfaction as traditional cigarettes.

[0003] Due to existing heated cigarette processing technology (such as...) Figure 1 The existing heating cigarette production process (as shown) presents several problems and limitations. Firstly, only one type of sheet can be used for processing, and formula adjustments can only be made during sheet processing. This makes product design, testing, and adjustment difficult and time-consuming, hindering the rapid response to market demands and product development. Secondly, propylene glycol, glycerol, or their derivatives or polymers have strong hygroscopic properties, leading to numerous difficulties and increased costs in the processing and packaging of heated cigarette raw materials, the rolling and packaging of heated cigarette sticks, and quality control. In actual cigarette production, it was found that sheets containing propylene glycol, glycerol, or their derivatives or polymers, and heated cigarette sticks using these materials, can increase moisture content by 1.5% after just 20 minutes in summer, severely impacting product quality and smoking experience. Furthermore, the loss of propylene glycol, glycerol, or their derivatives or polymers during sheet processing is significant, resulting in high energy consumption. Therefore, reducing product design complexity, effectively applying propylene glycol, glycerol, or their derivatives or polymers, and controlling their hygroscopicity are among the most pressing issues to be addressed in heated cigarette production.

[0004] Therefore, there is an urgent need for a method and apparatus to reduce the amount of atomizing agent applied to heated cigarettes. Summary of the Invention

[0042] As Figure 1The existing heating cigarette processing process mainly includes: reconstituted tobacco manufacturing process and cigarette manufacturing process. In the reconstituted tobacco manufacturing process, the tobacco raw material is screened, impurities are removed, extracted, solid-liquid separated, refined and concentrated. The solid obtained by solid-liquid separation is successively subjected to beating, papermaking, coating, drying, rolling, uncoiling, roll pressing, glue application, drying, slitting and rewinding, vacuum packaging, and then enters the cigarette manufacturing process. In the cigarette manufacturing process, the package is removed, the tobacco is uncoiled, tensioned, rolled and cut into shreds, flavored, bundled and formed, wrapped in cigarette paper, cut into cigarettes, and connected to a filter rod to form a cigarette. After the refining and concentrating processes, the concentrated liquid is mixed with an atomizing agent and a flavoring agent, and then coated. Before the glue application process, the sol process and the glue preparation process are required.

[0043] The existing heating cigarette processing process has many problems and limitations. On the one hand, only one kind of sheet can be processed, and the formula style adjustment can only be realized during the sheet processing process. The product design, testing and adjustment are difficult and time-consuming, which is not conducive to quickly meeting market demand and product research and development. On the other hand, propylene glycol, glycerol or their derivatives or polymers have strong hygroscopicity, which brings many difficulties and cost increases to the processing and packaging of heating cigarette raw materials, the packaging and processing of heating cigarette rods, and quality control. In actual silk production, it is found that the moisture content of the sheet to which propylene glycol, glycerol or their derivatives or polymers are applied and the heating cigarette rod using the sheet increases by 1.5% after being placed for 20 minutes in summer, which seriously affects product quality and smoking experience. Propylene glycol, glycerol or their derivatives or polymers and other atomizing agents have the problems of high loss and high energy consumption during the sheet processing process.

[0044] Therefore, how to reduce product design difficulty, apply propylene glycol, glycerol or their derivatives or polymers and control their hygroscopicity is one of the problems to be solved in the production process of heating cigarettes. Currently, the sheet to which propylene glycol or glycerol is applied is often coated with a barrier layer on the surface to control its hygroscopicity. Sealed packaging is used to prevent moisture absorption during storage, but this method has many defects such as increased process, high cost and complex equipment, and still has the problem of moisture absorption. Therefore, how to fully develop the potential of existing equipment, reduce equipment investment, reduce the viscosity of glycerol, improve the atomization effect, improve the absorption rate of glycerol, and improve the production efficiency is still a problem to be solved in the production process of heating cigarettes.

[0045] As shown in Figure 2 The method for reducing the amount of heating cigarette atomizing agent applied provided by the present embodiment includes the following steps in actual execution:

[0046] The heating cigarette reconstituted tobacco manufacturing process and the heating cigarette rod manufacturing process are successively performed, and the heating cigarette reconstituted tobacco manufacturing process includes the following steps:

[0047] In the manufacturing process of the reconstituted tobacco for the heat-not-burn cigarette, the tobacco raw material is sequentially subjected to a screening process, a foreign matter removing process, an extraction process, and a solid-liquid separation process, to obtain solid and liquid phase materials, respectively;

[0048] The liquid phase material obtained through the solid-liquid separation process is subjected to a refining and concentrating process to obtain a concentrated liquid;

[0049] The solid material obtained through the solid-liquid separation process is sequentially subjected to a beating process, a papermaking process, a coating process, a drying process, a rolling process, an unrolling process, a roll pressing and densifying process, a slitting and rewinding process, and a packaging process, wherein, in the coating process, the concentrated liquid obtained through the refining and concentrating process is mixed with flavoring and perfumes and then coated.

[0050] In the manufacturing process of the heat-not-burn cigarette, after the removal of the packaging, the cigarette is sequentially subjected to a packaging removal process, an unrolling process, a flavoring process, a roll pressing and cutting process, a bunching and forming process, a wrapping with cigarette paper process, a cigarette slitting process, and a filter rod tipping process, to form a cigarette, wherein, in the flavoring process, flavoring and fogging agents are mixed and then applied.

[0051] Figure 3 A structural schematic diagram of an existing cigarette forming and flavoring device is shown, which includes a sheet roll 1, a pressing roller 2, a turning roller 3, a tensioning roller 4, a cutting roller 5, a valve 6, a sheet filament 7, and a cigarette gun 8. Figure 4 A structural schematic diagram of an embodiment of the device for reducing the application amount of the fogging agent for the heat-not-burn cigarette is shown, which includes a feeding pipe 10, a first unrolling device 11, a second unrolling device 12, a first pressing roller 13, a second pressing roller 14, a first turning roller 15, a second turning roller 16, a first tensioning roller 17, a second tensioning roller 18, a valve 19, an applicator 20, a cutting roller 21, a sheet filament 22, and a cigarette gun 23.

[0052] In the slitting and rewinding process, the slitting width of the sheet is half of the width of a single sheet. In the present application, the hygroscopic fogging agent such as propylene glycol and glycerol is applied from the coating liquid preparation and coating process of the sheet processing process for the heat-not-burn cigarette as shown in Figure 1 to remove only the tobacco extract concentrate and flavoring and perfumes, so that the loss of the fogging agent in the drying process and the energy consumption can be reduced; at the same time, the sizing and moisture-proof enhancement in Figure 1 the drying process are removed, the process flow is shortened, the energy consumption and production time are reduced; after drying, the sheet is slit, rolled, and packaged; the Figure 2 slitting and rewinding process in Figure 1 is changed to

[0053] Further, the unrolling process specifically includes:

[0054] Two thin rolls of the same width are respectively installed on the first unwinding device 11 and the second unwinding device 12, wherein the unwinding speed of the thin rolls on the first unwinding device 11 and the second unwinding device 12 is consistent with the speed of the cigarette rolling machine.

[0055] Furthermore, in the heated cigarette manufacturing process, after removing the packaging, the cigarette proceeds sequentially through the following steps: packaging removal, unrolling, flavoring, rolling and cutting, bundling and forming, wrapping with cigarette paper, cigarette slitting, and attaching filter rods, to form the cigarette. Specifically, this includes:

[0056] After being unwound by the first unwinding device 11, the sheet is pressed flat by the first pressure roller 13, oriented by the first steering roller, and tensioned by the first tensioning roller. After being coated with a mixture of misting agent and fragrance by the applicator, it enters the shredding roller for shredding.

[0057] After being unwound by the second uncoiling device 12, the sheet is successively flattened by the second pressure roller, oriented by the second steering roller, tensioned by the second tensioning roller, and coated with a mixture of misting agent and fragrance by the applicator before entering the shredding roller for shredding.

[0058] The shredded thin strips 22 are fed into the cigarette gun and undergo rolling, cigarette cutting, conveying, and assembly processes to form heated cigarettes. The production process is then completed through box packaging, carton packaging, and package packaging.

[0059] Furthermore, the environmental requirements for the fragrance addition process are a humidity (RH) of less than 65% and a temperature of no more than 28°C. The existing production process environmental conditions are a humidity (RH) of less than 40% and a temperature of no more than 24°C. Therefore, the present invention significantly reduces the requirements for environmental temperature and humidity, requiring no technical transformation, no separate area or air conditioning system, and no technical transformation to control the humidity of the production area. It can utilize the existing packaging workshop, thus reducing the investment in technical transformation.

[0060] Furthermore, in the fragrance application process, the fragrance application method is a topical application, which is a modification of the existing injection method. Figure 3 (As shown) The fragrance application method is changed to a topical application. Specifically, in some embodiments of the present invention, the specific steps of the fragrance application process are as follows:

[0061] Mix the atomizing agent and fragrance liquid evenly, and pour the mixture into a temporary storage tank before production, according to the production plan.

[0062] Apply the mixture of misting agent and fragrance liquid between two thin sheets of the same width using a smearing method.

[0063] In the present application, the first sheet installed on the first unwinding device 11 and the second sheet installed on the second unwinding device 12 are sheets with the same width. In some embodiments of the present application, the first sheet and the second sheet are completely identical sheets. In other embodiments of the present application, the first sheet and the second sheet are sheets of different types and styles, so as to provide more abundant means for products. The present application does not make specific limitations in this regard.

[0064] In the present application, the hygroscopic fogging agent such as propylene glycol and glycerol is applied to Figure 2 The process of applying the fogging agent and the flavoring liquid to the two sheets is shown in the process of applying the flavoring liquid to the two sheets before Figure 1 The process of applying the foging agent and the flavoring liquid to the two sheets is shown in the process of applying the flavoring liquid to the two sheets after Figure 2 The process of applying the fogging agent and the flavoring liquid to the two sheets is shown in the process of applying the flavoring liquid to the two sheets before

[0065] Further, the process of cutting the two sheets includes the following steps:

[0066] The two sheets after the application of the mixture of the fogging agent and the flavoring liquid are overlapped and enter the cutting device for cutting. The pressure between the two cutting rollers is used to press the fogging agent and the flavoring liquid into the two sheets, and the cut tobacco of the two sheets is assembled together. One of the two cutting rollers serves as a cutting roller, and the other serves as a supporting roller. The pressure between the cutting roller and the supporting roller is used to press the foging agent and the flavoring liquid into the sheets, so as to promote the penetration and absorption of the fogging agent and the flavoring liquid, avoid the formation of yellow spots due to the excessive proportion of the flavoring liquid in the original process, and affect the product quality. Meanwhile, the cut tobacco of the first sheet and the second sheet is assembled together, which has better strength and is beneficial to the continuous processing of the product.

[0067] In some embodiments of the present application, the process flow for manufacturing the reconstituted tobacco leaf for heating cigarettes is shown in Figure 2 In the present application, the hygroscopic fogging agent such as propylene glycol and glycerol is applied to

[0068] Before production, the two sheet reels are installed on the first unwinding device 11 and the second unwinding device 12, respectively. The unwinding speed of the sheet reels of the first unwinding device 11 and the second unwinding device 12 automatically tracks the speed of the cigarette making machine and remains consistent. The application proportion, the pressure of the cutting roller 21, and other related equipment parameters are set on the equipment control panel according to the process requirements.

[0069] The fogging agent and the flavoring liquid are mixed uniformly according to the formula requirements and the application amount requirements of the fogging agent, and are sent to the workshop and poured into the online flavoring system equipment tank for standby.

[0070] In production, the first unwinding device 11 unwinds the sheet, which is sequentially pressed flat by the first compression roller 13, is adjusted by the first turning roller 5, is tensioned by the first tensioning roller 17, and then enters the cutting roller 21 after the mixed solution of the fogging agent and the fragrance is applied by the applicator 20 in a smearing manner. The second unwinding device 12 unwinds the sheet, which is sequentially pressed flat by the second compression roller 14, is adjusted by the second turning roller 16, is tensioned by the second tensioning roller 18, and then enters the cutting roller 21 after the mixed solution of the fogging agent and the fragrance is applied by the applicator 20 in a smearing manner. The cut sheet filament 22 is sent to the cigarette gun 23 to go through the processes of rolling, cigarette cutting, conveying, tipping, and the like, and then goes through the processes of box, strip, and piece packaging to complete the production process.

[0071] The comparison results of the fogging agent application amount of products of different processes and the comparison results of the sensory quality of different application processes are shown in Table 1 and Table 2, respectively.

[0072] Table 1 Comparison of fogging agent application amount of products of different processes

[0073]

[0074] Application process Aroma Fogging Consistency Sheet manufacturing process application (prior art) 7 7 7 Cigarette forming process application (present invention) 7 7.1 7

[0075] As can be seen from Table 1, the fogging agent application amount is reduced by 16 percentage points, and as can be seen from Table 2, the sensory quality of the sheets of the two processes is basically the same, and there is no obvious difference.

[0076] The method for reducing the fogging agent application amount of heated cigarettes provided by the embodiment of the present application simplifies the process flow, omits the processes and devices of sheet fogging agent application, glue application, and vacuum packaging, reduces equipment investment and energy consumption, and almost has no loss in the fogging agent application process.

[0077] Correspondingly, as shown in Figure 4 the present application also provides a device for reducing the fogging agent application amount of heated cigarettes, which comprises:

[0078] The first unwinding device 11 and the second unwinding device 12 are arranged side by side, the rear end of the first unwinding device 11 is sequentially provided with the first compression roller 13, the first turning roller 15, and the first tensioning roller 17, and the rear end of the second unwinding device 12 is sequentially provided with the second compression roller 14, the second turning roller 16, and the second tensioning roller 18.
