Description

Technical Field

[0001] This invention relates to the field of tobacco technology, and in particular to a production line for reusing heated cigarettes and conventional cigarettes. Background Technology

[0002] In recent years, with the increasingly stringent tobacco control situation and consumers' growing awareness of health, new tobacco products have become increasingly popular. Heated cigarettes and other aerosol-generating products have achieved a good smoking experience after rapid development and optimization in recent years. However, due to the special heating method of heated cigarettes, existing traditional cigarette tobacco cannot be used as the filler material. Therefore, reconstituted tobacco leaves, i.e., tobacco sheets, are mostly used as filler materials. These sheets are mainly composed of tobacco dust, tobacco leaf fragments, tobacco stems, or low-grade tobacco leaves, with the addition of adhesives and other additives. They are mainly prepared by three methods: papermaking, slurry processing, and rolling. They differ significantly from traditional tobacco leaves and require new production lines, such as the equipment mentioned in Chinese patent CN103561593A. In addition, the density of tobacco sheets produced by the slurry method and the roll pressing method is relatively high, while the mechanical strength of tobacco sheets produced by the papermaking method is relatively high. Therefore, when using tobacco sheets to roll heated cigarettes, problems such as large fluctuations in cigarette weight, difficulty in twisting and splicing, and easy blockage of the cigarette rolling machine are likely to occur, making the rolling process more difficult. Existing cigarette rolling equipment cannot meet the yield requirements of industrial production.

[0003] There have been attempts to use traditional cigarette tobacco in heated cigarettes to release sufficient aroma compounds under heating conditions. However, adding large amounts of atomizing agents directly to the tobacco can cause it to clump together, hindering rolling and contaminating the production line, thus affecting the production of other products. Even with pre-treatment of traditional tobacco, such as steam explosion and freeze-drying, new equipment is required. Furthermore, steam explosion and freeze-drying equipment pose safety hazards for cigarette factories, necessitating the construction of separate facilities outside the factory grounds. These pre-treatments also significantly reduce the processability of the tobacco, resulting in a low yield of whole tobacco strands and difficulties in rolling and splicing them on the production line.

[0004] Therefore, it is necessary to invent a completely new tobacco processing technology for heated cigarettes, so that traditional cigarette production lines can be reused with heated cigarettes with only minor modifications. Summary of the Invention

[0005] To address the shortcomings of existing technologies and practical needs, this invention provides a reuse production line for producing heated cigarettes and traditional cigarettes. This reuse production line can be modified from existing traditional cigarette production lines to achieve reuse with heated cigarettes.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a reusable production line for producing heated and conventional cigarettes, comprising: a tobacco sheet processing section, a tobacco shred processing section, and a cigarette rolling section, wherein the tobacco sheet processing section includes: an unpacking device, a slicing device, a loosening and rehydration device, a feeding device, and a leaf storage device, wherein:

[0008] The feeding device includes a first liquid source and a second liquid source. The first liquid source contains cell wall degrading enzymes, and the second liquid source contains conventional liquid. The feeding device sprays the first liquid onto the tobacco sheet to produce heated cigarette tobacco sheet, or the feeding device sprays the second liquid onto the tobacco sheet to produce conventional cigarette tobacco sheet.

[0009] The leaf storage device includes a first leaf storage cabinet and a second leaf storage cabinet. The first leaf storage cabinet is used to store the heated cigarette tobacco sheets and perform cell wall enzyme degradation treatment, while the second leaf storage cabinet stores the conventional cigarette tobacco sheets and performs conventional liquid permeation.

[0010] Furthermore, the reuse production line includes a production line control system, which controls the feeding device to spray the first liquid onto the heated cigarette sheet and transfer it to the first leaf storage cabinet according to the type of cigarette being manufactured, or the production line control system controls the feeding device to spray the second liquid onto the conventional cigarette sheet and transfer it to the second leaf storage cabinet according to the type of cigarette being manufactured.

[0011] Furthermore, the production line control system controls the temperature of the first leaf storage cabinet to be 25-30℃, 30-35℃, 35-40℃, 40-45℃, 45-50℃, 50-55℃, or 55-60℃; controls the relative humidity of the first leaf storage cabinet to be 15-20%, 20-25%, 25-30%, 30-35%, 35-40%, 40-45%, 45-50%, 50-55%, 55-60%, 60-65%, 65-70%, 70-75%, or 75-80%; and controls the storage time of the first leaf storage cabinet to be 0.5-1.0h, 1.0-2.0h, 2.0-4.0h, 4.0h-6.0h, 6.0-8.0h, 8.0-12.0h, or 12.0-24.0h.

[0012] Furthermore, the production line control system controls the components of the first liquid in the first liquid source. The first liquid is an aqueous solution and / or an organic solution of an active enzyme. The active enzyme components include any one or a combination of at least two of pectinase, hemicellulase, cellulase and amylase.

[0013] Furthermore, the tobacco processing section cuts the heated cigarette sheet into heated cigarette tobacco, or the tobacco processing section cuts the conventional cigarette sheet into conventional cigarette tobacco.

[0014] Furthermore, the feeding device also includes a third liquid source, which includes a third liquid that serves as an aerosol generator or a humectant. The production line control system controls the feeding device to add the third liquid, which serves as an aerosol generator, to the heated cigarette sheet according to the type of cigarette being manufactured.

[0015] Furthermore, the production line control system controls the feeding device to add a humectant as the third liquid to the conventional cigarette sheet according to the type of cigarette being manufactured.

[0016] Furthermore, the tobacco processing section includes a blending and flavoring device, which further includes a fourth liquid source. The fourth liquid source includes a fourth liquid containing a protease. The production line control system controls the blending and flavoring device to add the fourth liquid, which serves as an aerosol generating agent, to the heated tobacco shreds according to the type of cigarette being manufactured.

[0017] Furthermore, the blending and flavoring device also includes a fifth liquid source, which includes a fifth liquid that serves as an aerosol generator or a humectant. The production line control system controls the feeding device to add the fifth liquid, which serves as an aerosol generator, to the heated cigarette sheet according to the type of cigarette being manufactured. Alternatively, the production line control system controls the feeding device to add the fifth liquid, which serves as a humectant, to the conventional cigarette sheet according to the type of cigarette being manufactured.

[0018] Furthermore, the cigarette rolling section includes a cigarette rolling device and a receiving device. The cigarette rolling device rolls the heated cigarette tobacco into heated cigarette tobacco segments or rolls the traditional cigarette tobacco into traditional cigarette tobacco segments. The receiving device, under the control of the production line control system, receives the heated cigarette tobacco segments and the heated cigarette filter segments, or the receiving device, under the control of the production line control system, receives the traditional cigarette tobacco segments and the traditional cigarette filter segments.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The production line for reusing heated and conventional cigarettes provided by this invention can controllably modify conventional cigarette tobacco, enabling it to absorb more aerosols and release more aroma substances during heating, while maintaining its original processability (especially the whole tobacco yield) and using existing equipment conditions. This allows conventional cigarette production lines to be reused with heated cigarettes with only minor modifications, significantly reducing the cost of rebuilding or modifying the production line. By selecting specific degrading enzyme compositions and enzymatic hydrolysis conditions, the enzymatic degradation reaction can be achieved in the existing leaf storage environment without the need for additional high-temperature reaction equipment.

[0026] To further illustrate the technical means and effects of this invention, the following description, in conjunction with embodiments and accompanying drawings, provides a further explanation of the invention. It is understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0027] The following detailed description of the features and advantages of the present invention is sufficient to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly. Furthermore, based on the specification, claims and drawings disclosed herein, those skilled in the art can easily understand the related objects and advantages of the present invention.

[0028] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during 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 orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, the production line for producing heated cigarettes and reusing traditional cigarettes according to the present invention includes: a tobacco sheet processing section 100, a tobacco shred processing section 200, a blending and flavoring device 250, a cigarette rolling section 300, and a production line control system. The production line control system includes one or more processors (CPUs), input / output devices or interfaces, wired or wireless network interfaces, and memory. Input devices include human-machine interface devices to receive control information from operators, including cigarette type and formula. The memory stores computer programs and / or computer instructions, which, when executed by the processor, control the production line.

[0032] The tobacco leaf processing section 100 includes an unpacking device 110, a metering device, a slicing device 130, a loosening and rehydration device 150, a tobacco leaf pre-mixing device, a screening device, a feeding device 170, and a leaf storage device 180. After the tobacco leaves have been threshed, re-dried, and aged, they are sent to the reuse production line in boxes and need to go through processes such as unpacking and metering, slicing, loosening and rehydration, tobacco leaf pre-mixing, screening and feeding, leaf mixing and storage. First, according to the leaf group formula requirements of the product, the tobacco leaves are prepared for feeding. The unpacking device 110 is used to unpack the tobacco leaves. The unpacking process involves removing the outer packaging box and then cutting the tobacco sheets into several pieces of a specified thickness using a slicing device 130. These pieces are then loosened and rehydrated using a loosening and rehydration device 150 and a tobacco sheet pre-mixing device to improve the tobacco sheets' processing resistance and to initially and evenly mix them. Fragments are then removed using a sieving device, and tobacco processing liquid is sprayed onto the tobacco sheets using a feeding device 170. Finally, the selected tobacco sheets are evenly mixed and stored in a leaf storage device 180 for use in the next process stage.

[0033] like Figure 2 As shown, the feeding device 170 of the reuse production line of the present invention includes a first liquid source 171 and a second liquid source 172.

[0034] The first feed liquid in the first feed liquid source 171 contains a cell wall degrading enzyme. The first feed liquid can be an organic solution of an active enzyme composition, with the solvent being an atomizing agent composed of glycerol, propylene glycol, and water. The active enzyme composition includes one or more of pectinase, hemicellulase, cellulase, and amylase. In one specific embodiment, the weight ratio of pectinase, hemicellulase, and amylase is: pectinase: 15-25%; hemicellulase: 32-48%; amylase: 32-48%. The hemicellulase in the above ratio can also be replaced by cellulase.

[0035] In one specific embodiment, any one of the active enzyme formulations numbered G1-G6 in Table 1 (all bioenzymes are commercially available products from Beijing Xiasheng Biotechnology Development Co., Ltd.) can be used. With the ratio of active enzyme to tobacco dry weight being 0.5-2.0%, especially 1-1.5%, the cell wall degradation of the tobacco leaves can be achieved quickly and fully in the conventional storage environment of the leaf storage cabinet. Too little will not achieve the expected effect in the existing leaf storage cabinet, while too much will lead to excessive off-flavors in the final product.

[0036] Table 1: Formulation of Active Enzyme Composition

[0037]

[0038] The second liquid source 172 contains a conventional liquid. The feeding device 170 may have two nozzles respectively connected to the first liquid source 171 and the second liquid source 172, so that it can select to spray the first liquid to produce heated cigarette sheet 21 or spray the second liquid to produce conventional cigarette sheet 22 according to the instructions issued by the production line control system.

[0039] In one specific embodiment, the nozzle of the feeding device 170 is connected to a three-way valve, and the production line control system controls the three-way valve to selectively connect to the first liquid source 171 or the second liquid source 172 to spray the first liquid or the second liquid onto the tobacco sheet.

[0040] In one specific embodiment, the first liquid can be an aqueous solution of the active enzyme composition. In this case, the feeding device 170 also includes a third liquid source 173, which includes an aerosol (also known as an aerosol generator). The aerosol contains glycerol and / or propylene glycol. The flavoring device 350 can quantitatively add the aerosol to the heated cigarette sheet 21 according to the instructions of the production line control system. Adding the aerosol before the enzymatic reaction allows the aerosol to quickly fill the interior of the tobacco cell wall after enzymatic hydrolysis, enabling the tobacco to fully absorb the aerosol and avoiding the problem of the tobacco not being able to disperse or clumping when it is cut into shreds by the shredder 210. The almost absence of aerosol residue on the tobacco surface can avoid contaminating the production line, especially preventing the cigarette rolling section 300 from rolling. Since the glycerol and propylene glycol in the cigarette product are absorbed in the cell wall, the probability of contact with moisture in the air is reduced, the apparent water absorption is reduced, and thus the shelf life is improved.

[0041] Different heated cigarettes can have different aerosol dosages and formulations. The aerosol can account for 7.5-10.0%, 10.0-12.5%, 12.5-15.0%, 15.0-17.5%, 17.5-20.0%, 20.0-22.5%, 22.5-25.0%, 25.0-27.5%, or 27.5-30.0% of the dry weight of the heated cigarette tobacco sheet 21. The weight ratio of glycerol to propylene glycol can be 10:0-8:2, 8:2-6:4, 6:4-5:5, 5:5-4:6, 4:6-2:8, or 2:8-10:0. The third liquid source 173 can contain the pre-mixed aerosol, or it can have multiple compartments to store glycerol, propylene glycol, or other components separately, and output each component quantitatively according to the product formulation requirements.

[0042] In another embodiment, the third liquid source 173 storing glycerin can quantitatively add glycerin to the heated cigarette sheet 21 or the conventional cigarette sheet 22 according to the instructions of the production line control system. Adding a large amount of glycerin (e.g., more than 12% of the dry weight of tobacco) can be used as an atomizing agent in the heated cigarette sheet 21, while adding a small amount of glycerin (e.g., less than 2% of the dry weight of tobacco) can be used as a humectant in the conventional cigarette sheet 22. The third liquid source 173 can have multiple liquids storing different components, thereby realizing online mixing and reuse of liquids.

[0043] The leaf storage device 180 includes a first leaf storage cabinet 181 and a second leaf storage cabinet 182. Heated cigarette sheets sprayed with the first liquid are sent to the first leaf storage cabinet 181 for cell wall enzymatic degradation treatment. The production line control system maintains the first leaf storage cabinet 181 at a high temperature, typically 28-33℃, with a relative humidity of 67-75%. By controlling the storage time, the degree of cell wall enzymatic degradation can be controlled, thereby quantifying the apparent or microscopic aerosol loading of the final cigarette sheet. A storage time of 2-4 hours is ideal; too short a time will not allow for sufficient aerosol loading, while too long a time is uneconomical and reduces processability. Conventional cigarette sheets sprayed with the second liquid are then sent to the second leaf storage cabinet 182 for conventional liquid infiltration. The production line control system has a non-processable tobacco material identification system, which can identify tobacco sheets or shredded tobacco with a low expected whole-shred ratio, or tobacco sheets or shredded tobacco that have not been processed according to the system's internal standard process. Identification of non-processable tobacco materials will trigger automatic rejection, an alarm, or a production line shutdown. Because the modified heated cigarette tobacco sheet 21 of this invention has high processability, the non-processable tobacco sheet identification system of the production line control system will not identify it as a non-processable tobacco sheet and trigger automatic rejection, an alarm, or a production line shutdown. Therefore, the heated cigarette shredded tobacco 31 can be directly processed through the tobacco shredding section 200 of a traditional tobacco production line using processes such as shredding. Similarly, the production line can also process traditional cigarette tobacco sheets 22 into traditional cigarette shredded tobacco 32.

[0044] The tobacco processing section 200 includes a shredding device 210, a drying device 230, and a blending and flavoring device 250. First, the shredding device 210 shreds the heated cigarette tobacco sheets 21 to form heated cigarette tobacco shreds 31 of a certain width. Then, the drying device 230 dries the tobacco shreds. This step, besides drying the heated cigarette tobacco shreds 31 to remove some moisture (to achieve a specified moisture content, for example, 11.5%–14.0%), thereby improving the filling capacity and sensory quality of the tobacco shreds, also includes a high-temperature rapid drying process (temperature 200-250℃, preferably 235℃; time 1-10s, preferably 3-5s) to inactivate residual enzyme combinations in the heated cigarette tobacco shreds 31. Finally, the blending and flavoring device 250 further adds flavorings and additives suitable for heated cigarettes to the heated cigarette tobacco shreds 31, before sending it to the cigarette rolling section 300. In one specific embodiment, the blending and flavoring device 250 includes a fourth liquid source containing a fourth liquid containing a protease, which can be used to degrade residual biological enzymes in the heated cigarette tobacco shreds 31, thereby reducing the off-flavors generated after heating. In another specific embodiment, the blending and flavoring device 250 includes a fifth liquid source containing a fifth liquid, which can be used as an aerosol or humectant, either as a supplement to or as a replacement for the flavoring device 170.

[0045] The 2021 Henan Sanmenxia Mianchi C3F Qinyan 96 flue-cured tobacco leaves were subjected to cell wall enzyme degradation treatment for 4 hours according to the various enzyme combinations in Table 1. After that, the tobacco leaves were shredded according to the above conventional method. The shredded tobacco leaves were shredded according to the "YC / T178-2003 Method for Determination of Whole Tobacco Leaf Rate and Broken Tobacco Leaf Rate" and the results are shown in Table 2.

[0046] Table 2: Whole Tobacco Shred Rate

[0047]

[0048] As can be seen, according to the processing technology of the present invention, under the premise that the tobacco can fully absorb the aerosol and there is almost no aerosol precipitation on the surface, the whole tobacco shred rate is maintained at more than 75%, thereby making the processability fully meet the requirements of the current cigarette production line and avoiding triggering the response mechanism of the non-processable tobacco material identification system.

[0049] The process for traditional cigarette tobacco sheets in the tobacco processing section 200 is basically the same. The cigarette rolling section 300 includes a cigarette rolling device 310 and a feeding device 330. The cigarette rolling device 310 can roll heated cigarette tobacco shreds 31 into heated cigarette tobacco segments 41, or it can roll traditional cigarette tobacco shreds 32 into traditional cigarette tobacco segments 42. The cigarette rolling device 310 can select the cigarette paper specifications, printing content, and rolling size according to the instructions of the production line control system. Under the control of the production line control system, the feeding device 330 feeds heated cigarette tobacco segments 41 and heated cigarette filter segments 51 into heated cigarettes 61, or it can feed traditional cigarette tobacco segments 42 and traditional cigarette filter segments 52 into traditional cigarettes 62. During the feeding process, the feeding device 330 can select the feeding paper specifications, printing content, and rolling size according to the instructions.
