[0002] Electric heated cigarettes are the main new tobacco products in the current market, and they have attracted the attention of tobacco industry enterprises. Electric heated cigarettes generally contain tobacco segments, that is, tobacco is processed by special processes and a certain proportion of atomizers such as glycerin is added. After homogenization, it is wrapped through cigarette or filter rod forming processes to become a part of heated cigarettes. Among them, the tobacco segments can be a single reconstituted tobacco leaf or other forms of tobacco materials such as particles. Therefore, two or more tobacco raw materials can be used through a blending process to prepare relatively homogeneous atomized tobacco.

[0070] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0071] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0072] The embodiments of the present application are written in a progressive manner.

[0073] like Figure 1 As shown, an embodiment of the present application provides a blending method for atomized tobacco shreds, comprising:

[0074] S101. Processing the tobacco raw material into a size of shredded tobacco to obtain processed tobacco raw material; wherein the tobacco raw material includes reconstituted tobacco leaves, and the processed tobacco raw material includes processed reconstituted tobacco leaf raw material; or, the tobacco raw material includes reconstituted tobacco leaves and non-reconstituted tobacco leaves, and the processed tobacco raw material includes processed reconstituted tobacco leaf raw material and processed non-reconstituted tobacco leaf raw material;

[0075] In S101, the tobacco raw material may include only reconstituted tobacco leaves, such as roll-pressed reconstituted tobacco leaves and paper-making reconstituted tobacco leaves, or may include reconstituted tobacco leaves and non-reconstituted tobacco leaves, such as roll-pressed reconstituted tobacco leaves and shredded stems; accordingly, the processed tobacco raw material includes processed reconstituted tobacco leaf raw material, or the processed tobacco raw material includes processed reconstituted tobacco leaf raw material and processed non-reconstituted tobacco leaf raw material; the tobacco shreds size of the tobacco raw material is processed to obtain the processed reconstituted tobacco leaf raw material, specifically: the tobacco shreds length of the reconstituted tobacco leaves is reasonably controlled to obtain the processed reconstituted tobacco leaf raw material; the tobacco shreds dimension of the non-reconstituted tobacco leaves is reasonably controlled to obtain the processed non-reconstituted tobacco leaf raw material; the purpose is to process the tobacco shreds length or tobacco shreds dimension of the tobacco raw material to avoid uneven blending and agglomeration of different tobacco raw materials due to different physical properties in the subsequent blending process. Among them, the physical properties of the tobacco raw materials can be characterized by the quantitative value or filling value of the tobacco raw materials. In particular, reconstituted tobacco leaves with low quantitative values ​​and high filling values ​​such as papermaking method and dry method are prone to agglomeration and are not easy to disperse evenly during the blending process when used as tobacco raw materials for blending. By processing the tobacco shreds size of the tobacco raw materials in this step, the occurrence of such situations can be effectively reduced, thereby improving the uniformity of tobacco blending.

[0076] S102. According to a preset formula, the treated tobacco raw material is blended to obtain a blended tobacco raw material;

[0077] In S102, the preset formula may include the blending ratio and total flow rate of the tobacco raw materials. Specifically, the blending may be performed based on an existing quantitative feeding and transmission system.

[0078] S103. Evenly mix the blended tobacco raw materials to obtain the first finished tobacco shreds.

[0079] In S103, specifically, uniform blending can be performed based on the existing tobacco shreds storage cabinet, for example, the blended tobacco raw materials are transported to the tobacco shreds storage cabinet; the tobacco shreds storage cabinet uniformly blends the blended tobacco raw materials and outputs the first finished tobacco shreds; using the tobacco shreds storage cabinet to perform uniform blending can make full use of traditional cigarette making processes and equipment, saving costs; preferably, according to product design, the first finished tobacco shreds can be output after the shreds are stored in the tobacco shreds storage cabinet for a certain period of time.

[0080] Atomized tobacco is generally in the form of reconstituted tobacco leaves. Due to the addition of atomizers such as glycerin, there are large differences between different blends, which makes it difficult to blend evenly. The existing silk-making technology and equipment are not suitable for the blending of formula tobacco shreds that are mainly reconstituted tobacco shreds containing atomizers.

[0081] In the present embodiment, by processing the tobacco shreds size of the tobacco raw material, the processed tobacco raw material is obtained: the tobacco shreds length of the reconstituted tobacco leaves is reasonably controlled to obtain the processed reconstituted tobacco raw material; the tobacco shreds dimension of the non-reconstituted tobacco leaves is reasonably controlled to obtain the processed non-reconstituted tobacco raw material; in the present embodiment, by processing the tobacco shreds length or tobacco shreds dimension of the tobacco raw material, and then blending and mixing, it is possible to avoid uneven blending and agglomeration of different tobacco raw materials due to different physical properties; therefore, the above technical scheme can improve the uniformity of blending of tobacco shreds mainly composed of reconstituted tobacco leaf shreds containing atomizers.

[0082] Based on the above embodiment, one implementation method of processing the tobacco shreds size of the tobacco raw material to obtain the processed tobacco raw material may include the following steps:

[0083] S201. When the tobacco raw material is reconstituted tobacco, the detection data of the reconstituted tobacco and the length of the tobacco segment of the cigarette are obtained, and the shredded length of the reconstituted tobacco is determined according to the detection data of the reconstituted tobacco and the length of the tobacco segment. According to the shredded length, the reconstituted tobacco is shredded to obtain the processed reconstituted tobacco raw material, wherein the detection data of the reconstituted tobacco includes a quantitative value and / or a filling value;

[0084] In S201, when the tobacco raw material is reconstituted tobacco, the detection data of the reconstituted tobacco is obtained, and the detection data of the reconstituted tobacco includes a quantitative value and / or a filling value; specifically, the physical property of the reconstituted tobacco can be tested before blending to obtain a quantitative value and / or a filling value; in actual production, the quantitative value of the tobacco raw material is generally 80 to 200 g / m 2 The filling value is generally between 2.5 and 6.0 g / cm 3 between; obtaining the tobacco segment length of the cigarette, which can be obtained according to a preset cigarette design scheme; the detection data of the reconstituted tobacco leaves and the method for obtaining the tobacco segment length do not affect the implementation of this embodiment; determining the shredded length of the reconstituted tobacco leaves according to the detection data of the reconstituted tobacco leaves and the tobacco segment length, which has the function of reasonably controlling the shredded length of the reconstituted tobacco leaves based on the detection data of the reconstituted tobacco leaves, i.e., the physical properties of the reconstituted tobacco leaves, and combining the tobacco segment length, so as to avoid the tobacco raw materials with different quantitative values ​​or filling values ​​from being the same shredded tobacco leaves as much as possible. The length of the tobacco shreds may lead to uneven blending and agglomeration; for example, the reconstituted tobacco leaves with low quantitative content and high filling value such as the papermaking method and the dry method can reduce the tendency of the tobacco leaves to agglomerate and be difficult to disperse evenly during the blending process by reasonably controlling the length of the tobacco shreds, thereby improving the uniformity of the tobacco blending; the reconstituted tobacco leaves are shredded according to the shredded length to obtain the processed reconstituted tobacco leaf raw material. Specifically, the reconstituted tobacco leaves can be shredded according to the shredded length through the existing shredding process to obtain the processed reconstituted tobacco leaf raw material.

[0085] S202. When the tobacco raw material is non-reconstituted tobacco, the dimensions of the shredded tobacco of the non-reconstituted tobacco are controlled to be within a preset dimension range to obtain processed non-reconstituted tobacco raw material.

[0086] In S202, when the tobacco raw material is non-reconstituted tobacco, such as expanded shreds, stem shreds and other non-filamentous tobacco raw materials with small physical dimensions and irregular shapes, such tobacco raw materials may not be cut into shreds, and the dimensions of the shredded tobacco of the non-reconstituted tobacco can be directly controlled within a preset dimensional range. The purpose is to avoid as much as possible the situation where tobacco raw materials exceeding the preset dimensional range are difficult to disperse evenly during the blending process, thereby improving the uniformity of tobacco blending; specifically, the maximum dimension length of the non-reconstituted tobacco can be controlled to be less than 10 mm.

[0087] like Figure 2 As shown, based on the above embodiment, in another embodiment of the present application, a blending method for atomized tobacco shreds is provided, comprising:

[0088] S301. Processing the tobacco raw material into a size of shredded tobacco to obtain processed tobacco raw material; wherein the tobacco raw material includes reconstituted tobacco leaves, and the processed tobacco raw material includes processed reconstituted tobacco leaf raw material; or, the tobacco raw material includes reconstituted tobacco leaves and non-reconstituted tobacco leaves, and the processed tobacco raw material includes processed reconstituted tobacco leaf raw material and processed non-reconstituted tobacco leaf raw material;

[0089] S302. According to a preset formula, the processed tobacco raw material is blended to obtain a blended tobacco raw material;

[0090] S303. The blended tobacco raw material is uniformly mixed to obtain a first finished tobacco shred;

[0091] For details of S301 to S303, please refer to Figure 1 S101 to S103 of the embodiment shown.

[0092] S304. Obtaining the detection data of the tobacco raw material;

[0093] In S304, the tobacco raw materials may include only reconstituted tobacco leaves, or may include reconstituted tobacco leaves and non-reconstituted tobacco leaves; the detection data of the tobacco raw materials may include quantitative values ​​or filling values; to obtain the detection data of the tobacco raw materials, physical properties of different tobacco leaf raw materials in the tobacco raw materials may be detected before blending to obtain quantitative values ​​or filling values; for example, when the tobacco raw materials include reconstituted tobacco leaves A and non-reconstituted tobacco leaves B, physical properties of the reconstituted tobacco leaves A and the non-reconstituted tobacco leaves B may be detected before blending to obtain quantitative values ​​or filling values ​​of the reconstituted tobacco leaves A and the reconstituted tobacco leaves B.

[0094] S305. Obtaining a first detection difference of the tobacco raw material according to the detection data of the tobacco raw material;

[0095] In S305, the first detection difference is the quantitative value difference or the filling value difference of the tobacco raw material; for example, when the tobacco raw material includes reconstituted tobacco leaves A and non-reconstituted tobacco leaves B, the quantitative value difference or the filling value difference of the reconstituted tobacco leaves A and the non-reconstituted tobacco leaves B is obtained according to the quantitative value or the filling value of the reconstituted tobacco leaves A and the non-reconstituted tobacco leaves B as the first detection difference.

[0096] S306. Determine whether the first detection difference is within a first preset range, if not, execute S307;

[0097] In S306, the first preset range is a first preset quantitative value difference range or a first preset filling value difference range; its function is to evaluate the size of the quantitative value difference or the filling value difference of different tobacco leaf raw materials in the tobacco raw material, that is, to evaluate the physical property difference of different tobacco leaf raw materials; for example, when the tobacco raw material includes reconstituted tobacco leaf A and non-reconstituted tobacco leaf B, the size of the quantitative value difference or the filling value difference of the reconstituted tobacco leaf A and the non-reconstituted tobacco leaf B is evaluated; if the first detection difference is within the first preset range, the first finished tobacco shreds can be directly output; if the first detection difference is not within the first preset range, subsequent processing should be continued; specifically, the first preset quantitative value difference range can preferably be [0, 30] g / m 2 The first preset filling value difference range may preferably be [0, 3.5] g / cm 3 .

[0098] S307. Evenly blend the first finished tobacco shreds to obtain second finished tobacco shreds.

[0099] In S307, when the first detection difference is not within the first preset range, the first finished tobacco is mixed evenly for a second time to obtain the second finished tobacco. The purpose of this is that when the first detection difference is not within the first preset range, that is, when the physical properties of different tobacco leaf raw materials in the tobacco raw materials are quite different, a second mixing is performed to improve the blending uniformity of the output finished tobacco.

[0100] In this embodiment, by judging the difference in the quantitative value or filling value of different tobacco leaf raw materials in the tobacco raw materials, when the difference in the quantitative value or filling value of different tobacco leaf raw materials in the tobacco raw materials is large, the first finished tobacco shreds are evenly mixed for a second time, so as to further reduce the uneven blending of different tobacco leaf raw materials in the tobacco raw materials due to excessive differences in physical properties, which is beneficial to improving the blending uniformity of the output finished tobacco shreds.

[0101] like Figure 3 As shown, based on the above embodiment, in another embodiment of the present application, a blending method for atomized tobacco shreds is provided, comprising:

[0102] S401. Processing the tobacco raw material into a size of shredded tobacco to obtain processed tobacco raw material; wherein the tobacco raw material includes reconstituted tobacco leaves, and the processed tobacco raw material includes processed reconstituted tobacco leaf raw material; or, the tobacco raw material includes reconstituted tobacco leaves and non-reconstituted tobacco leaves, and the processed tobacco raw material includes processed reconstituted tobacco leaf raw material and processed non-reconstituted tobacco leaf raw material;

[0103] S402. According to a preset formula, the treated tobacco raw material is blended to obtain a blended tobacco raw material;

[0104] S403. The blended tobacco raw material is uniformly mixed to obtain a first finished tobacco shred;

[0105] For details of S401 to S403, please refer to Figure 1 S101 to S103 of the embodiment shown.

[0106] S404. Determine whether the first finished tobacco needs to be dried and flavored. If so, execute S405; if not, execute S406;

[0107] In S404, the drying and flavoring can be completed based on existing flavoring, shredded tobacco drying, moisture content adjustment and other processes; whether the first finished shredded tobacco needs to be dried and flavored can be determined based on actual production needs.

[0108] S405. Drying and flavoring the first finished tobacco shreds, and evenly blending the first finished tobacco shreds that have been dried and flavored to obtain third finished tobacco shreds;

[0109] In S405, when the first finished tobacco shreds need to be further dried and flavored after being discharged, a second uniform mixing can be performed after the drying and flavoring process to obtain the third finished tobacco shreds, thereby completing the tobacco blending; in this way, the blending uniformity of the output finished tobacco shreds can be improved while maintaining cost control.

[0110] S406. Obtaining the detection data of the tobacco raw material;

[0111] S407. Obtaining a first detection difference of the tobacco raw material according to the detection data of the tobacco raw material;

[0112] S408. Determine whether the first detection difference is within a first preset range, if not, execute S409;

[0113] S409. Evenly blend the first finished tobacco shreds to obtain second finished tobacco shreds.

[0114] Among them, the detection data of the tobacco raw material includes quantitative values, the first detection difference is the quantitative value difference of the tobacco raw material, and the first preset range is the first preset quantitative value difference range; or, the detection data of the tobacco raw material includes filling values, the first detection difference is the filling value difference of the tobacco raw material, and the first preset range is the first preset filling value difference range.

[0115] For details of S406 to S409, please refer to Figure 2 S304 to S307 of the embodiment shown.

[0116] In this embodiment, when the first finished tobacco shreds need to be dried and flavored after being discharged, a second uniform blending can be performed after the drying and flavoring process is completed, so as to improve the blending uniformity of the output finished tobacco shreds while maintaining cost control; when the first finished tobacco shreds do not need to be dried and flavored after being discharged, the method described in the following can be continued. Figure 2 In steps S304 to S307 of the illustrated embodiment, when the quantitative values ​​or filling values ​​of different tobacco leaf raw materials in the tobacco raw materials differ greatly, the first finished tobacco shreds are evenly mixed for a second time, so as to further reduce the uneven blending of different tobacco leaf raw materials in the tobacco raw materials due to excessive differences in physical properties, which is beneficial to improving the blending uniformity of the output finished tobacco shreds.

[0117] On the basis of the above embodiment, one implementation method of determining the cut length of the reconstituted tobacco leaves according to the detection data of the reconstituted tobacco leaves and the length of the tobacco segment may include the following steps:

[0118] S501. Comparing the quantitative value of the reconstituted tobacco leaf with a preset quantitative value to obtain a quantitative value comparison result, and determining the cut length of the reconstituted tobacco leaf according to the quantitative value comparison result and the length of the tobacco segment;

[0119] or,

[0120] S502. Compare the filling value of the reconstituted tobacco leaf with a preset filling value to obtain a filling value comparison result, and determine the cut length of the reconstituted tobacco leaf according to the filling value comparison result and the length of the tobacco segment.

[0121] In this embodiment, the length of the shredded tobacco of the reconstituted tobacco is controlled by the quantitative value or filling value of the reconstituted tobacco, combined with the length of the tobacco segment in the heated cigarette, and the preset quantitative value or preset filling value, to obtain the shredded length of the reconstituted tobacco. Specifically, taking the tobacco segment length of the mainstream heated cigarette product as 12mm as an example, in S501, the quantitative value of the reconstituted tobacco is compared with the quantitative upper threshold value of 150g / m in the preset quantitative value. 2 When the quantitative value of the reconstituted tobacco leaf is greater than the quantitative high threshold, the shredded length of the reconstituted tobacco leaf is determined to be any value between [20, 30] cm; the quantitative value of the reconstituted tobacco leaf is compared with the quantitative low threshold of 120 g / m in the preset quantitative value. 2 When the quantitative value of the reconstituted tobacco leaf is less than the quantitative lower threshold, the cut length of the reconstituted tobacco leaf is determined to be any value in [10, 20] cm; in S502, the filling value of the reconstituted tobacco leaf is compared with the filling value lower threshold 2.8 g / cm in the preset filling value. 3When the filling value of the reconstituted tobacco leaf is less than the filling value low threshold, the shredded length of the reconstituted tobacco leaf is determined to be any value in [20, 30] cm; the filling value of the reconstituted tobacco leaf is compared with the filling value high threshold 4.0 g / cm in the preset filling value. 3 For comparison, when the filling value of the reconstituted tobacco leaf is greater than the filling value high threshold, the shredded length of the reconstituted tobacco leaf is determined to be any value in the range of [10, 20] cm; in this embodiment, according to the quantitative value or filling value of the reconstituted tobacco leaf, combined with the tobacco segment length, and the preset quantitative value or preset filling value, the shredded length of the reconstituted tobacco leaf is reasonably controlled, which can avoid as much as possible the situation where tobacco raw materials with different quantitative values ​​or filling values ​​are mixed unevenly and agglomerated due to the same tobacco shred length, which is beneficial to improving the uniformity of the blending of tobacco shreds mainly composed of reconstituted tobacco leaf shreds containing atomizers.

[0122] On the basis of the above embodiment, in another embodiment of the present application, a method for blending atomized tobacco shreds is provided, comprising:

[0123] S601.

[0124] S602. According to a preset formula, the processed tobacco raw material is blended to obtain a blended tobacco raw material;

[0126] For details of S601 to S603, please refer to Figure 1 S101 to S103 of the embodiment shown.

[0127] S604. According to a preset cycle, the first finished tobacco is tested for atomizer content to obtain a test result of atomizer content;

[0128] In S604, the purpose is to detect the atomizer content of the first finished tobacco shreds, and to characterize the uniformity of the blending of the finished tobacco shreds by detecting the atomizer content of the finished tobacco shreds; specifically, samples can be uniformly taken at the finished tobacco shreds outlet according to 5 preset time periods to detect the atomizer content (such as glycerol content, propylene glycol content, CV value, etc.) of the first finished tobacco shreds.

[0129] S605. Determine whether the atomizer content detection result meets the preset detection requirements, if not, execute S606;

[0130] In S605, the preset detection requirement may be formulated according to actual production requirements. Specifically, it may be determined whether the CV value is less than 2%.

[0131] S606. Evenly mix the first finished tobacco shreds to obtain second finished tobacco shreds.

[0132] In S606, when the atomizer content detection result does not meet the preset detection requirements, the uniformity of tobacco blending is improved by secondary uniform mixing; in other embodiments, the first finished tobacco can also be re-mixed uniformly, and the atomizer content of the re-mixed finished tobacco can be detected until the finished tobacco meets the preset detection requirements.

[0133] Based on the above embodiment, in another embodiment, when the atomizer content detection result does not meet the preset detection requirement, the step S601 can be returned to execute to reprocess the tobacco shreds size of the tobacco raw material, for example, by redesigning the tobacco shreds length to improve the uniformity of tobacco blending until the finished tobacco shreds that meet the preset detection requirement are obtained; it should be noted that the above atomizer content detection process is not limited to the first finished tobacco shreds, and it can also be performed on any finished tobacco shreds; the above uniform mixing process or tobacco shreds length adjustment process can be repeated multiple times until the atomizer content detection result meets the preset detection requirement.

[0134] On the basis of the above embodiment, one implementation method of blending the processed tobacco raw material according to the preset formula to obtain the blended tobacco raw material may include the following steps:

[0135] S701. Placing the processed tobacco raw material on a plurality of conveyor belts, and determining the flow parameters of each conveyor belt according to a preset blending ratio and a preset total flow rate;

[0136] In S701, the preset blending ratio and the preset total flow rate can be set according to actual production requirements. The flow parameter of the conveyor belt can be the material flow rate (kg / h) of the conveyor belt, which can be calculated according to the following formula:

[0137] Material flow = total material flow × material mixing ratio

[0138] S702. According to the flow parameters, control the conveyor belt to blend the processed tobacco raw material to obtain blended tobacco raw material.

[0139] In this embodiment, the existing quantitative feeding transmission system can be used to complete the blending of the processed tobacco raw materials through clocked flow control. It is only necessary to improve the transmission angle and spatial arrangement of the conveyor belt, etc. The changes are relatively small, and the traditional cigarette making process and equipment can be fully utilized to save costs.

[0140] On the basis of the above embodiment, placing the processed tobacco raw material on multiple conveyor belts, and determining the flow parameters of each conveyor belt according to a preset blending ratio and a preset total flow rate may include the following steps:

[0141] S801. According to the preset blending ratio, determine whether there is a tobacco raw material with a consistent blending ratio in the processed tobacco raw material, if so, execute S802, if not, execute S806;

[0142] In S801, it is first determined whether there is tobacco raw material with a consistent blending ratio in the processed tobacco raw material.

[0143] S802. Acquire the detection data of the tobacco raw materials with the same blending ratio;

[0144] In S802, the detection data of the tobacco raw material with a consistent blending ratio includes a quantitative value or a filling value.

[0145] S803. Obtaining a second detection difference value of the tobacco raw material with a consistent blending ratio according to the detection data of the tobacco raw material with a consistent blending ratio;

[0146] In S803, the second detection difference is a quantitative value difference or a filling value difference of the tobacco raw materials with the same blending ratio.

[0147] S804. Determine whether the second detection difference is within a second preset range, if yes, execute S805, if no, execute S806;

[0148] In S804, the second preset range is a second preset quantitative value difference range or a second preset filling value difference range, and its purpose is to confirm the difference in the quantitative value or filling value of the tobacco raw materials with the same blending ratio. Specifically, the preset second quantitative value difference range and the preset second filling value difference range can be set to zero.

[0149] S805. placing the tobacco raw materials with the same blending ratio on the same conveyor belt, placing the tobacco raw materials with inconsistent blending ratios in the processed tobacco raw materials on different conveyor belts, and determining the flow parameters of each conveyor belt according to the preset blending ratio and the preset total flow;

[0150] In S805, when the second detection difference is within the second preset range, the tobacco raw materials with consistent blending ratio are placed on the same conveyor belt, and the tobacco raw materials with inconsistent blending ratios in the processed tobacco raw materials are placed on different conveyor belts, so that the production cost can be saved by sharing the conveyor belt under the premise of ensuring the blending effect; for example, blending is performed according to the following ratio according to the preset formula: 80% reconstituted tobacco leaf shreds A + 10% stem shreds + 10% ordinary shredded tobacco, and the 80% reconstituted tobacco leaf shreds A adopts the flow design: material flow (kg / h) = total flow × blending ratio 80%; it has been verified that the filling values ​​of both 10% stem shreds and 10% ordinary shredded tobacco are 4.0g / cm 3 , then the stem shreds and ordinary shredded tobacco share a conveyor belt, and its flow design is: material flow (kg / h) = total flow × blending ratio 20%.

[0151] S806. Placing the processed tobacco raw materials on different conveyor belts, and determining the flow parameters of each conveyor belt according to a preset blending ratio and a preset total flow rate;

[0152] In S806, when there is no tobacco raw material with a consistent blending ratio in the processed tobacco raw material, or when the second detection difference is not within the second preset range, the processed tobacco raw material is placed on different conveyor belts.

[0153] In the above embodiment, the conveyor belt can preferably be a V-shaped or deep arc groove to overcome the stratification of tobacco with different quantitative values ​​during the transmission process; in the above embodiment, the drop of the discontinuous transfer between the conveyor belts and between the conveyor belt and the tobacco storage cabinet is within a preset drop range. Since the different components of the atomized tobacco contain a high proportion of atomizers such as glycerin, the moisture content of the tobacco is relatively low (<10%), and the quantitative value of the main raw materials is large, which is easy to break during the transmission and blending process. By controlling the drop during the transmission process, breakage can be effectively avoided, and the quality and uniformity of the finished atomized tobacco can be improved. Preferably, the preset drop range is set to [0, 0.5] m.

[0157] The tobacco shred mixing device 12 is used to evenly mix the blended tobacco raw materials to obtain the first finished tobacco shreds;

[0158] Wherein, the tobacco raw material includes reconstituted tobacco leaves, and the processed tobacco raw material includes processed reconstituted tobacco leaf raw material;

[0159] Alternatively, the tobacco raw material includes reconstituted tobacco leaves and non-reconstituted tobacco leaves, and the processed tobacco raw material includes processed reconstituted tobacco leaf raw material and processed non-reconstituted tobacco leaf raw material.
