[0015] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure.

[0016] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation on the present disclosure, its application, or use.

[0017] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be regarded as part of the specification.

[0018] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0019] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0020] In the related art, mainly by combining the sensory evaluation results of formulators and the results of chemical composition analysis of tobacco product raw materials, a suitable processing path is selected for each tobacco product raw material used to prepare tobacco products. In this way, on the one hand, organizing formulators to conduct suction evaluations on tobacco product raw materials and chemical composition analysis on each tobacco product raw material takes a lot of time, resulting in low efficiency of grouped processing; on the other hand, the sensory evaluation results of formulators are highly subjective, resulting in low reliability of grouped processing. As a result, the production efficiency of tobacco products is low, and the quality of the final products is difficult to guarantee.

[0021] The inventors of the present disclosure have found through research that the quality grade of tobacco products is affected by the quality of the tobacco product raw materials used and the processing method of the tobacco product raw materials. Different quality tobacco product raw materials exhibit different pyrolysis characteristics during the pyrolysis process, which makes the focus of their processing different.

[0022] For example, high-quality tobacco product raw materials usually contain rich volatile aroma components, which can release strong, delicate and rich-layered aromas during the pyrolysis process, that is, the aroma volatilization characteristics are strong, so they are often used to produce tobacco products with higher quality grades. Moreover, due to the strong aroma volatilization characteristics, high-quality tobacco product raw materials are more likely to retain their aromas during the processing. Therefore, the focus of processing high-quality tobacco product raw materials can be on removing their bad components or further exerting their combustion potential, so as to further improve the quality of the prepared tobacco products.

[0023] In contrast, the content of volatile aroma components in low-quality tobacco product raw materials is low, and the aroma generated during pyrolysis is relatively weak, lacking richness and layering, that is, the aroma volatilization characteristics are weak, so they are often used to produce tobacco products with lower quality grades. However, due to the weak aroma volatilization characteristics, low-quality tobacco product raw materials are more likely to lose their aromas during processing. Therefore, the focus of processing low-quality tobacco product raw materials is on retaining their limited aromas, so as to improve the quality of the prepared tobacco products as much as possible.

[0024] The pyrolysis reaction is one of the main chemical reactions that occur when tobacco product raw materials (such as tobacco leaves) are continuously heated in the temperature range above the pyrolysis threshold temperature. The pyrolysis characteristics of tobacco product raw materials can be characterized by collecting data such as the temperature and mass change rate of the raw materials during the reaction. During the pyrolysis process of tobacco product raw materials, the pyrolysis behavior in different temperature ranges can reflect different pyrolysis characteristics of tobacco product raw materials. For example, the pyrolysis behavior in some temperature ranges reflects the combustion characteristics of tobacco product raw materials, while the pyrolysis behavior in some temperature ranges reflects the aroma volatilization characteristics of tobacco product raw materials.

[0025] In view of this, according to the pyrolysis characteristics of each tobacco product raw material in different temperature ranges and the quality grade of the target tobacco product to be prepared, a suitable processing path can be specifically selected for each tobacco product raw material to efficiently and reliably group-process the tobacco product raw materials, so as to improve the production efficiency of tobacco products and the quality of the final products.

[0026] An embodiment of the present disclosure provides a method for grouped processing of tobacco product raw materials. The method can use the thermogravimetric analysis data of each tobacco product raw material for preparing a target tobacco product as an objective analysis basis, and extract characteristic data reflecting the corresponding pyrolysis characteristics from the thermogravimetric analysis data of each tobacco product raw material according to the quality grade of the target tobacco product. Subsequently, a suitable processing path is matched for each tobacco product raw material in combination with the extracted characteristic data and the quality grade of the target tobacco product, so as to perform efficient and reliable grouped processing on each tobacco product raw material.

[0027] Figure 1 FIG. shows a flowchart of a method for grouped processing of tobacco product raw materials according to some embodiments of the present disclosure. As Figure 1 shown, for example, the method for grouped processing of tobacco product raw materials may include steps 110 to 140.

[0028] In step 110, thermogravimetric analysis data of each tobacco product raw material among a plurality of tobacco product raw materials for preparing a target tobacco product is obtained.

[0029] In the present disclosure, a tobacco product is a product made entirely or partially from tobacco leaves as raw materials and is used for smoking, chewing, nasal inhalation, or other uses. Tobacco products may include, but are not limited to, cigarettes, cigars, pipe tobacco, or hookah, etc. From the perspective of tobacco leaf formula and processing technology, cigarettes may include, but are not limited to, flue-cured tobacco, burley tobacco, oriental tobacco, or sun-cured tobacco, etc. Tobacco products release chemical substances such as nicotine (commonly known as "tobacco alkali") through heating (e.g., heat-not-burn tobacco products) and / or combustion (e.g., cigarettes, cigars, etc.). Tobacco products may or may not have a cigarette paper wrapper, and may or may not have a filter tip. In the present disclosure, for the convenience of description, in some cases, cigarettes are taken as examples of tobacco products for illustration. However, it should be recognized that various characteristics or limitations described here for cigarettes also apply to other types of tobacco products.

[0030] Tobacco product raw materials may include tobacco leaves in various forms. For example, they may be tobacco leaves or cut tobacco, tobacco flakes, tobacco powder, or tobacco blocks formed by processing tobacco leaves. In some embodiments, the tobacco product raw materials may be tobacco leaves from a specific origin. Here, the plurality of tobacco product raw materials may be tobacco leaves from different origins, or tobacco leaves from different growth parts of the same origin (e.g., classified as "upper", "middle", and "lower" according to the growth part of the tobacco leaf on the tobacco plant), or tobacco leaves from different batches of the same growth part of the same origin.

[0031] The thermogravimetric analysis data of each tobacco product raw material includes a plurality of pyrolysis temperatures of the pyrolysis process of each tobacco product raw material and the mass change rate of each tobacco product raw material corresponding to each pyrolysis temperature among the plurality of pyrolysis temperatures. For example, the plurality of pyrolysis temperatures may form a plurality of temperature ranges.

[0032] For example, the thermogravimetric analysis data of tobacco product raw materials can be obtained by conducting a pyrolysis experiment on the tobacco product raw materials and recording multiple pyrolysis temperatures during the pyrolysis process and the mass change rate of the tobacco product raw materials corresponding to each pyrolysis temperature. The mass change rate can be determined by taking the derivative of the mass change amount of the tobacco product raw materials during the pyrolysis process with respect to temperature.

[0033] Taking a certain tobacco leaf as an example of the tobacco product raw materials, the process of conducting a pyrolysis experiment on the tobacco product raw materials will be exemplarily introduced below.

[0034] First, place a certain tobacco leaf in a constant temperature and humidity chamber to equilibrate for a period of time. After that, grind the tobacco leaf, filter and fully mix the ground tobacco powder through a sieve, and weigh, for example, 10 mg of the tobacco powder as a sample. In a thermal analyzer, heat the sample in a nitrogen atmosphere (for example, the flow rate of nitrogen is 50 milliliters per minute (i.e., the carrier gas flow rate is 50 mL / min)) at a certain rate (for example, 10 Kelvin per minute (10 K / min)) to a certain temperature (for example, 373 Kelvin (K)), and keep it at a constant temperature for a period of time to remove the influence caused by different moisture contents of the tobacco leaf. Then, continue to heat the sample to a higher temperature (for example, 630 Kelvin (K)) at the same rate. Record the relationship between the mass and temperature of the sample during the heating process to obtain a thermogravimetric (TG) curve. To make the tobacco pyrolysis behavior more obvious, take the derivative of the TG curve to obtain a derivative thermogravimetric (DTG) curve (also referred to as the "thermogravimetric analysis curve" hereinafter), which reflects the relationship between the mass change rate and temperature, that is, the "thermogravimetric analysis data" described in this article. If the thermogravimetric analysis data is presented in the form of a curve graph (i.e., the DTG curve), its abscissa represents temperature (i.e., the "pyrolysis temperature" described in this article), with the unit of Kelvin (K), and the ordinate represents the mass change rate of the tobacco leaf during pyrolysis, with the unit of percentage / kelvin (% / K). This curve is also called a thermal analysis spectrum.

[0035] Here, it can be understood that the pyrolysis temperature in the thermogravimetric analysis data (i.e., the abscissa of the DTG curve) can reflect the temperature change range of the tobacco leaf during pyrolysis, and different pyrolysis temperatures may correspond to different pyrolysis stages in the pyrolysis reaction. The mass change rate in the thermogravimetric analysis data (i.e., the ordinate of the DTG curve) can reflect the intensity of the reaction of the tobacco leaf during pyrolysis, thereby revealing the kinetic characteristics of the pyrolysis reaction of the tobacco leaf.

[0036] The multiple pyrolysis temperatures in the thermogravimetric analysis data can be evenly distributed or unevenly distributed. To more accurately characterize the pyrolysis characteristics of tobacco leaves, the temperature difference between adjacent pyrolysis temperatures among the multiple pyrolysis temperatures can be as small as possible, for example, it can be 10K, 5K, 1K, 0.5K or other values.

[0037] In step 120, according to the quality grade of the target tobacco product, a characteristic temperature range is determined from multiple temperature ranges.

[0038] The quality grade is used to reflect the quality of the tobacco product. The higher the quality grade, the better the quality of the tobacco product. In some embodiments, the quality grade of the target tobacco product can be reflected by the selling price. Therefore, the quality grade of the target tobacco product can be determined based on its selling price. For example, the quality grade of the target tobacco product can be positively correlated with its selling price. The higher the selling price of the target tobacco product, the higher its quality grade.

[0039] In some embodiments, different quality grades can correspond to different characteristic temperature ranges. For example, the characteristic temperature range corresponding to a quality grade exceeding (or higher than) a specified grade can be different from the characteristic temperature range corresponding to a quality grade not exceeding the specified grade.

[0040] On this basis, in some further embodiments, different quality grades can correspond to the same characteristic temperature range. For example, if the number of quality grades exceeding a specified grade is multiple, these multiple quality grades can correspond to the same characteristic temperature range. Another example is that if the number of quality grades not exceeding a specified grade is multiple, these multiple quality grades correspond to the same characteristic temperature range.

[0041] Taking the quality grades of tobacco products including five quality grades as an example, assume that the quality grades from high to low are A1 quality grade, A2 quality grade, A3 quality grade, A4 quality grade and A5 quality grade in sequence. The A1 quality grade and the A2 quality grade can correspond to the characteristic temperature range Q1, and the A3 quality grade, the A4 quality grade and the A5 quality grade can correspond to the characteristic temperature range Q2. For example, the characteristic temperature range Q1 and the characteristic temperature range Q2 can be different. That is to say, the tobacco products can be grouped according to the quality grades of the tobacco products. The tobacco products within the same group correspond to the same characteristic temperature range, while the tobacco products in different groups correspond to different characteristic temperature ranges.

[0042] In step 130, according to the characteristic data corresponding to the characteristic temperature range, the mass change amount of each tobacco product raw material within the characteristic temperature range is determined.

[0043] Here, the characteristic data includes the characteristic temperature within the characteristic temperature range and the mass change rate corresponding to the characteristic temperature.

[0044] It should be understood that the thermogravimetric analysis data of each tobacco product raw material can form a DTG curve, wherein the characteristic data corresponding to the characteristic temperature range forms a part of the curve in the DTG curve.

[0045] In some embodiments, the mass change amount of each tobacco product raw material within the characteristic temperature range can be determined according to the area of the thermogravimetric analysis curve formed by the characteristic data.

[0046] Figure 2 A schematic diagram of a thermogravimetric curve according to some embodiments of the present disclosure is shown.

[0047] Taking the tobacco product raw material as tobacco leaves as an example, Figure 2 Schematically shows the thermogravimetric curves (i.e., DTG curves) of tobacco leaf A, tobacco leaf B, and tobacco leaf C within the temperature range [400K, 630K].

[0048] Taking the DTG curve of tobacco leaf A as an example, assuming that the temperature range [400K, 500K] is the determined characteristic temperature range, the area of the DTG curve formed by the characteristic data corresponding to the temperature range [400K, 500K] is the area enclosed by a part of the curve of the DTG curve of tobacco leaf A between the abscissa [400K, 500K] and the abscissa (the abscissa passes through the point on the ordinate where the mass change rate is 0), as Figure 2 shown by the shaded part.

[0049] For example, the area of the thermogravimetric analysis curve formed by the characteristic data can be accurately calculated by integrating the mass change rate within the characteristic temperature range.

[0050] For another example, the area of the thermogravimetric analysis curve formed by the characteristic data can be approximately calculated based on the trapezoidal rule. Assume that the characteristic temperature range is divided into n sub - ranges, and the upper limit, lower limit, and height of the i - th (1 ≤ i ≤ n) sub - range are a i , b i , h i . The trapezoidal area formula Si=(a i + b i )h i / 2 is used to approximately calculate the area Si of the thermogravimetric analysis curve formed by the i - th sub - range, and then the n areas corresponding to the n sub - ranges are added together to obtain the total area S as the area of the thermogravimetric analysis curve formed by the characteristic data.

[0051] In a further embodiment, the area of the thermogravimetric analysis curve formed by the characteristic data of each tobacco product raw material is positively correlated with the mass change of the tobacco product raw material within the characteristic temperature range. For example, the larger the area of the thermogravimetric analysis curve formed by the characteristic data of each tobacco product raw material, the greater the mass change of the tobacco product raw material within the characteristic temperature range, which means that the characteristics exhibited by the tobacco product raw material within the characteristic temperature range are stronger. Conversely, they are weaker.

[0052] In step 140, according to the quality grade of the target tobacco product and the mass change of each tobacco product raw material within the characteristic temperature range, each tobacco product raw material is assigned to the corresponding processing path for processing.

[0053] In some embodiments, the processing path may include multiple processing techniques with different processing intensities. For example, the processing path may include a drum processing technique with a relatively small processing intensity and a pneumatic processing technique with a relatively large processing intensity.

[0054] In some embodiments, for target tobacco products of different quality grades, each tobacco product raw material can be assigned to the corresponding processing path for processing according to the magnitude of the mass change of each tobacco product raw material used therein within the characteristic temperature range. Some embodiments will be further described below in conjunction with this.

[0055] In the above embodiments, the quality grade of the target tobacco product to be prepared is taken into account in the grouped processing design of the tobacco product raw materials. The characteristic data corresponding to the corresponding characteristic temperature range is extracted from the thermogravimetric analysis data of each tobacco product raw material according to the quality grade of the target tobacco product, and then combined with the characteristic data and the quality grade of the target tobacco product, the corresponding processing path is assigned to each tobacco product raw material.

[0056] In this way, on the one hand, the thermogravimetric analysis data of each tobacco product raw material and the quality grade of the target tobacco product are combined for objective analysis to select the processing path of each tobacco product raw material, reducing subjective errors and improving the reliability of grouped processing; on the other hand, there is no need to spend a lot of time on chemical composition analysis and tissue suction evaluation, improving the efficiency of grouped processing. Thus, the grouped processing of tobacco product raw materials can be carried out efficiently and reliably, improving the production efficiency of tobacco products and the quality of the final product.

[0057] First, some embodiments will be combined below to give an exemplary illustration of the related implementation of step 120, that is, determining the characteristic temperature range according to the quality grade of the target tobacco product.

[0058] In some embodiments, in response to the quality level being the first quality level, the first temperature range among a plurality of temperature ranges is determined as the characteristic temperature range; in response to the quality level being the second quality level lower than the first quality level, the second temperature range among the plurality of temperature ranges is determined as the characteristic temperature range.

[0059] Here, the first temperature range is associated with the combustion characteristics (also referred to as "combustion characteristics") of each tobacco product raw material, and the second temperature range is associated with the fragrance volatilization characteristics (also referred to as "main characteristics") of each tobacco product raw material.

[0060] That is to say, if the quality level of the target tobacco product is relatively high, corresponding processing paths can be assigned to each tobacco product raw material based on the characteristic data corresponding to the characteristic temperature range associated with the combustion characteristics of each tobacco product raw material. If the quality level of the target tobacco product is relatively low, corresponding processing paths can be assigned to each tobacco product raw material based on the characteristic data corresponding to the characteristic temperature range associated with the fragrance volatilization characteristics of each tobacco product raw material.

[0061] In this way, considering that the quality of each tobacco product raw material used in the target tobacco product with a relatively high quality level is usually good, the corresponding fragrance volatilization characteristics are relatively strong and the differences are small. Therefore, the characteristic data corresponding to the characteristic temperature range associated with the combustion characteristics of each tobacco product raw material is used as the basis to select the corresponding processing path for each tobacco product raw material, so as to further exert the combustion potential of each tobacco product raw material through processing, thereby further improving the quality of the final product.

[0062] In contrast, considering that the quality of each tobacco product raw material used in the target tobacco product with a relatively low quality level is usually poor, the corresponding fragrance volatilization characteristics are relatively weak and the differences are large. Therefore, the characteristic data corresponding to the characteristic temperature range associated with the fragrance volatilization characteristics of each tobacco product raw material is used as the basis to select the corresponding processing path for each tobacco product raw material, so as to retain the limited aroma of each tobacco product raw material as much as possible through processing, thereby improving the quality of the final product.

[0063] In some embodiments, there may be an overlap or no overlap between the first temperature range and the second temperature range. For example, the upper limit of the second temperature range is less than or equal to the lower limit of the first temperature range.

[0064] For example, the upper limit of the second temperature range is equal to the lower limit of the first temperature range. That is, the first temperature range and the second temperature range are continuous. Taking the temperature range formed by multiple pyrolysis temperatures in the thermogravimetric analysis data of each tobacco product raw material as [400K, 630K] as an example, the second temperature range can be [400K, 500K], and the first temperature range can be [500K, 630K].

[0065] Thus, due to the overlap between the two temperature ranges, the possibility of data omission caused by discontinuous range division is reduced, and the thermogravimetric analysis data of each tobacco product raw material can be more completely and fully utilized in the analysis process, improving the accuracy of the processing path analysis based on the thermogravimetric analysis data of each tobacco product raw material, and further improving the reliability of grouped processing.

[0066] In some embodiments, the thermogravimetric curve formed by the thermogravimetric analysis data of each tobacco product raw material includes peaks associated with combustion characteristics and peaks associated with flavor volatilization characteristics. The first temperature range covers the peaks associated with combustion characteristics, and the second temperature range covers the peaks associated with flavor volatilization characteristics. For example, the number of peaks associated with combustion characteristics can be one or more. The number of peaks associated with flavor volatilization characteristics can be one or more.

[0067] Continuing to refer to Figure 2 , such as Figure 2 shown, the second temperature range can be [400K, 500K], and the second temperature range covers the peaks associated with flavor volatilization characteristics. The first temperature range can be [500K, 630K], and the first temperature range covers the peaks associated with combustion characteristics.

[0068] It should be understood that for the DTG curve of each tobacco leaf, Figure 2 only one peak associated with flavor volatilization characteristics covered by the second temperature range and one peak associated with combustion characteristics covered by the first temperature range are schematically marked. In some cases, the second temperature range can cover multiple peaks associated with flavor volatilization characteristics, and the first temperature range can cover multiple peaks associated with combustion characteristics.

[0069] In this way, considering that different peaks in the thermogravimetric analysis curve usually correspond to different reaction stages where the tobacco product raw material undergoes significant mass changes. For example, the peaks associated with combustion characteristics correspond to the combustion process of the tobacco product raw material at a higher temperature, mainly involving the pyrolysis of cellulose, hemicellulose, and lignin; while the peaks associated with flavor volatilization characteristics correspond to the thermal decomposition process of the tobacco product raw material at a lower temperature, mainly involving the pyrolysis of sugars, nicotine, pectin, and some other volatile substances.

[0070] Therefore, by dividing the temperature range according to the peak type of the thermogravimetric analysis curve, making the first temperature range cover the peak associated with the combustion characteristics, and analyzing the combustion behavior of the tobacco product raw material at a higher temperature by analyzing the characteristic temperature and mass change amount of the peak associated with the combustion characteristics, the combustion characteristics of the tobacco product raw material can be analyzed more accurately; and making the second temperature range cover the peak associated with the flavor volatilization characteristics, and analyzing the pyrolysis behavior of the tobacco product raw material at a lower temperature by the characteristic temperature and mass change amount of the peak associated with the flavor volatilization characteristics, the flavor volatilization characteristics of the tobacco product raw material can be analyzed more accurately. Thus, the characteristics of each reaction stage of the thermogravimetric process can be identified more precisely, which helps to improve the reliability of subsequent grouped processing and further improve the quality of the final product.

[0071] Next, some embodiments will be combined to exemplarily illustrate the related implementation of step 140, that is, allocating corresponding processing paths for each tobacco product raw material.

[0072] In some embodiments, when the quality grade of the target tobacco product is the first quality grade, the tobacco product raw materials with a mass change amount greater than or equal to the first specified threshold within the characteristic temperature range are allocated to the first processing path for processing, and the tobacco product raw materials with a mass change amount less than the first specified threshold are allocated to the second processing path for processing.

[0073] Here, the processing intensity of the second processing path is less than that of the first processing path.

[0074] As mentioned above, for a target tobacco product with a higher quality grade, corresponding processing paths can be allocated for each tobacco product raw material according to the characteristic data corresponding to the characteristic temperature range associated with the combustion characteristics of each tobacco product raw material.

[0075] Based on this, considering that the strength of the combustion characteristics of each tobacco product raw material is positively correlated with the magnitude of the mass change amount determined based on its associated characteristic data. That is, for each tobacco product raw material, if the mass change amount determined based on the characteristic data associated with the combustion characteristics is larger, it indicates that the combustion characteristics of the tobacco product raw material are stronger; conversely, if the mass change amount determined based on the characteristic data associated with the combustion characteristics is smaller, it indicates that the combustion characteristics of the tobacco product raw material are weaker.

[0076] Therefore, allocating tobacco product raw materials with a large mass variation (i.e., stronger combustion characteristics) to the first processing path with a higher processing intensity (such as airflow processing technology) for processing can fully tap the combustion potential of the tobacco product raw materials; while allocating tobacco product raw materials with a small mass variation (i.e., weaker combustion characteristics) to the second processing path with a lower processing intensity (such as drum processing technology) for processing can reduce the possibility of quality degradation due to excessive processing, thereby maximizing the advantages of group processing and optimizing the quality of the final product.

[0077] In some embodiments, when the quality grade of the target tobacco product is the first quality grade, the plurality of tobacco product raw materials may be sorted in descending order according to the amount of mass change. For example, the plurality of tobacco product raw materials may be sorted in descending order according to the amount of mass change within the first temperature interval.

[0078] Then, a first number of tobacco product raw materials ranked first among the plurality of tobacco product raw materials are allocated to a first processing path for processing, and other tobacco product raw materials among the plurality of tobacco product raw materials are allocated to a second processing path for processing. Here, the processing intensity of the second processing path is less than the processing intensity of the first processing path.

[0079] For example, seven tobacco product raw materials are sorted in descending order according to the mass change in the first temperature range, namely Y1, Y2, Y3, Y4, Y5, Y6, and Y7. Among them, the top three tobacco product raw materials (i.e., Y1, Y2, and Y3 with larger mass changes) can be allocated to a first processing path with greater processing intensity for processing, and the remaining four tobacco product raw materials (i.e., Y4, Y5, Y6, and Y7 with smaller mass changes) can be allocated to a second processing path with smaller processing intensity for processing.

[0080] In this way, on the one hand, the combustion potential of the tobacco product raw materials that are ranked first can be fully utilized, and on the other hand, the possibility of the quality of the final product being reduced due to excessive processing of the remaining other tobacco product raw materials can be reduced, thereby maximizing the advantages of group processing and optimizing the quality of the final product.

[0081] In some embodiments, the first number may be determined according to the machining flow rates of the first machining path and the second machining path.

[0082] For example, if the processing flow rate of the first processing path is greater than that of the second processing path, then correspondingly, the first quantity of tobacco product raw materials allocated for processing on the first processing path can be greater than the quantity of other tobacco product raw materials allocated for processing on the second processing path. If the processing flow rate of the first processing path is less than that of the second processing path, then correspondingly, the first quantity of tobacco product raw materials allocated for processing on the first processing path can be less than the quantity of other tobacco product raw materials allocated for processing on the second processing path. If the processing flow rate of the first processing path is equal to that of the second processing path, then correspondingly, the first quantity of tobacco product raw materials allocated for processing on the first processing path can be equal to the quantity of other tobacco product raw materials allocated for processing on the second processing path.

[0083] In this way, according to the processing flow rates of the two processing paths, the quantities of tobacco product raw materials allocated to the first processing path and the second processing path can be dynamically determined, so that the processing flow rates of the two processing paths are fully utilized, and the efficiency of grouped processing is improved.

[0084] In some embodiments, when the quality grade of the target tobacco product is the second quality grade, the tobacco product raw materials with a mass change amount within the characteristic temperature range less than the second specified threshold are allocated to the first processing path for processing, and the tobacco product raw materials with a mass change amount greater than or equal to the second specified threshold are allocated to the second processing path for processing.

[0085] Here, the processing intensity of the second processing path is less than that of the first processing path.

[0086] In some embodiments, the second specified threshold can be the same as or different from the first specified threshold.

[0087] As described above, for target tobacco products with a lower quality grade, corresponding processing paths can be allocated to each tobacco product raw material based on the characteristic data corresponding to the characteristic temperature range associated with the fragrance volatilization characteristics of each tobacco product raw material.

[0088] Based on this, considering that the strength of the fragrance volatilization characteristics of each tobacco product raw material is positively correlated with the magnitude of the mass change amount determined based on its associated characteristic data. That is, for each tobacco product raw material, if the mass change amount determined based on the characteristic data associated with the fragrance volatilization characteristics is larger, it indicates that the fragrance volatilization characteristics of this tobacco product raw material are stronger; conversely, if the mass change amount determined based on the characteristic data associated with the fragrance volatilization characteristics is smaller, it indicates that the fragrance volatilization characteristics of this tobacco product raw material are weaker.

[0089] Therefore, tobacco product raw materials with a large mass change (i.e., strong aroma volatility characteristics) are allocated to the second processing path with a lower processing intensity (such as a drum processing process) for processing, so as to retain the aroma of the tobacco product raw materials as much as possible; and tobacco product raw materials with a small mass change (i.e., weak aroma volatility characteristics) are allocated to the first processing path with a higher processing intensity (such as an airflow processing process) for processing to remove impurities, thereby maximizing the advantages of group processing and optimizing the quality of the final product.

[0090] In some embodiments, when the quality grade of the target tobacco product is the second quality grade, the multiple tobacco product raw materials may be sorted in descending order according to the mass change amount. For example, the multiple tobacco product raw materials may be sorted in descending order according to the mass change amount within the second temperature range.

[0091] Then, a second quantity of tobacco product raw materials ranked higher among the multiple tobacco product raw materials are allocated to the second processing path for processing, and other tobacco product raw materials among the multiple tobacco product raw materials are allocated to the first processing path for processing.

[0092] Here, the processing intensity of the second processing path is smaller than the processing intensity of the first processing path.

[0093] That is to say, the tobacco product raw materials with a higher ranking (i.e., a larger mass change) can be allocated to the second processing path with a lower processing intensity for processing, while the remaining tobacco product raw materials (i.e., a smaller mass change) can be allocated to the first processing path with a higher processing intensity for processing.

[0094] In this way, on the one hand, the aroma of the tobacco product raw materials ranked first can be retained as much as possible, and on the other hand, the impurities of the remaining other tobacco product raw materials can be removed, thereby maximizing the advantages of group processing and optimizing the quality of the final product.

[0095] In some embodiments, the second number may be determined according to the machining flow rates of the first machining path and the second machining path.

[0096] For example, if the processing flow rate of the second processing path is greater than the processing flow rate of the first processing path, the second quantity of tobacco product raw materials correspondingly allocated to the second processing path for processing may be greater than the quantity of other tobacco product raw materials allocated to the first processing path for processing. If the processing flow rate of the second processing path is less than the processing flow rate of the first processing path, the second quantity of tobacco product raw materials correspondingly allocated to the second processing path for processing may be less than the quantity of other tobacco product raw materials allocated to the first processing path for processing. If the processing flow rate of the second processing path is equal to the processing flow rate of the first processing path, the second quantity of tobacco product raw materials correspondingly allocated to the second processing path for processing may be equal to the quantity of other tobacco product raw materials allocated to the first processing path for processing.

[0097] In this way, the quantity of tobacco product raw materials allocated to the first processing path and the second processing path respectively can be dynamically determined according to the processing flow of the two processing paths, so that the processing flow of the two processing paths can be fully utilized and the efficiency of group processing can be improved.

[0098] Next, some embodiments are combined to illustrate how to adopt the technical solution of group processing disclosed in the present invention and the corresponding effects.

[0099] For example, for tobacco products P1 with a higher quality grade (such as Class II cigarettes), the group processing technical solution disclosed in the present invention is adopted for processing.

[0100] First, thermogravimetric analysis data of each of the multiple tobacco raw materials (e.g., tobacco leaves) used to prepare tobacco product P1 is obtained, wherein each tobacco raw material is named according to one or more elements of its origin, quality, and growth location. For example, "Brazil" represents tobacco raw materials produced in Brazil, and "Guizhou one or two categories" represents tobacco raw materials produced in Guizhou, grown in the middle of the country, and of quality belonging to one or two categories.

[0101] Table 1 schematically shows the thermogravimetric analysis data of some tobacco product raw materials.

[0102] Table 1

[0103] Suppose the tobacco product raw materials for preparing tobacco product P1 include 14 tobacco product raw materials. For each of these tobacco product raw materials, calculate the area of the DTG curve within the first temperature range (e.g., [500K, 630K]) as the mass change of the tobacco product raw material within the first temperature range, and calculate the area of the DTG curve within the second temperature range ([400K, 500K]) as the mass change of the tobacco product raw material within the second temperature range. Note that in this example, calculating the area of the DTG curve within the second temperature range as the mass change of the tobacco product raw material within the second temperature range is not necessary, and this result is only for reference.

[0104] Since the target tobacco product is tobacco product P1 with a relatively high quality grade, the first temperature range is determined as the characteristic temperature range, and each tobacco product raw material is assigned to the corresponding processing path for processing according to the magnitude of the mass change of each tobacco product raw material within the first temperature range.

[0105] For example, sort multiple tobacco product raw materials in descending order of the mass change within the first temperature range, and determine the first quantity of tobacco product raw materials assigned to the first processing path according to the processing flow rates of the first processing path and the second processing path. Then assign the first quantity of tobacco product raw materials with a higher ranking to the first processing path for processing, and assign the other tobacco product raw materials among the multiple tobacco product raw materials to the second processing path for processing.

[0106] Table 2 schematically shows the area of the DTG curve (also called the "combustion characteristic area") of each tobacco product raw material among the 14 tobacco product raw materials within the first temperature range, and the area of the DTG curve (also called the "main body characteristic area") within the second temperature range, as well as the allocation results of the corresponding processing paths.

[0107] Table 2

[0108] As an example, as shown in Table 2, the first processing path includes a relatively high-intensity air flow processing technology (also called the "air flow line"), and the second processing path includes a relatively low-intensity drum processing technology (also called the "drum line").

[0109] Suppose that according to the processing flow rates of the two processing paths, it is determined that the first quantity of the tobacco product raw materials allocated to the first processing path for processing is equal to the quantity of other tobacco product raw materials allocated to the second processing path for processing (i.e., the quantity of tobacco product raw materials is evenly divided). For these 14 tobacco product raw materials, in the order of the combustion characteristic area from large to small, the first 7 tobacco product raw materials with larger combustion characteristic areas (i.e., larger mass change amounts and stronger combustion characteristics) are allocated to the air flow line for processing, and the last 7 tobacco product raw materials with smaller combustion characteristic areas (i.e., smaller mass change amounts and weaker combustion characteristics) are allocated to the drum line for processing.

[0110] Then, organize multiple formulators to conduct sensory evaluation of the single-component tobacco products made from each of the 14 tobacco product raw materials shown in Table 2 through the air flow line and the drum line respectively, and based on the results of the sensory evaluation, allocate the processing paths for each tobacco product raw material.

[0111] For the same single-component tobacco product, subtract the number of people who think the product obtained by processing through the air flow line is better from the number of people who think the product obtained by processing through the drum line is better to obtain the data X1. If X1 is negative, then record the data X2 as 1, indicating that the quality of the product processed by the drum line is better than that of the product processed by the air flow line; if X1 is positive, then record the data X2 as 2, indicating that the quality of the product processed by the air flow line is better than that of the product processed by the drum line. The corresponding manual allocation results are shown in Table 3.

[0112] Table 3

[0113] It can be seen from the results shown in Table 3 that the allocation results of multiple formulators for the processing paths of these 14 tobacco product raw materials are basically the same as the results obtained by using the grouping processing technical solution proposed in the present disclosure. This indicates that for tobacco products with higher quality grades, the grouping processing technical solution proposed in the present disclosure can effectively replace the method of selecting the processing path based on the results of manual sensory evaluation, thereby eliminating the need to spend a large amount of time organizing manual sensory evaluation and improving the efficiency of grouping processing. Moreover, compared with the manual sensory evaluation method, the grouping processing method of the present disclosure is more objective and accurate, avoiding the uncertainty brought by human subjective factors.

[0114] For another example, for tobacco products P2 with lower quality grades (such as Class III cigarettes), the grouping processing technical solution of the present disclosure is adopted for processing.

[0115] First, obtain the thermogravimetric analysis data of each tobacco product raw material (such as tobacco leaves) used to prepare tobacco product P2. Similarly, each tobacco product raw material is named based on one or more elements among its place of origin, quality, and growth location.

[0116] Table 4 schematically shows the thermogravimetric analysis data of some tobacco product raw materials.

[0117] Assume that the tobacco product raw materials for preparing tobacco product P2 include 16 tobacco product raw materials. For each of these tobacco product raw materials, calculate the area of the DTG curve in the first temperature range (e.g., [500K, 630K]) as the mass change of the tobacco product raw material in the first temperature range, and calculate the area of the DTG curve in the second temperature range ([400K, 500K]) as the mass change of the tobacco product raw material in the second temperature range. Note that in this example, it is not necessary to calculate the area of the DTG curve in the first temperature range as the mass change of the tobacco product raw material in the first temperature range, and this result is only for reference.

[0118] Since the target tobacco product is tobacco product P2 with a lower quality grade, the second temperature range is determined as the characteristic temperature range, and each tobacco product raw material is assigned to the corresponding processing path for processing according to the magnitude of the mass change of each tobacco product raw material in the second temperature range.

[0119] For example, sort the multiple tobacco product raw materials in descending order of the mass change in the second temperature range, and determine the second quantity of the tobacco product raw materials assigned to the second processing path according to the processing flow rates of the first processing path and the second processing path. Then, assign the second quantity of the tobacco product raw materials with a higher ranking to the second processing path for processing, and assign the other tobacco product raw materials among the multiple tobacco product raw materials to the first processing path for processing.

[0120] Table 5 schematically shows the area of the DTG curve (also called the "combustion characteristic area") of each of the 16 tobacco product raw materials in the first temperature range and the area of the DTG curve (also called the "main body characteristic area") in the second temperature range, as well as the allocation results of the corresponding processing paths.

[0121] Table 5

[0122] As an example, as shown in Table 5, the first processing path includes an air flow processing process with a greater processing intensity (also called the "air flow line"), and the second processing path includes a drum processing process with a smaller processing intensity (also called the "drum line").

[0123] Suppose that according to the processing flow rates of the two processing paths, it is determined that the first quantity of the tobacco product raw materials allocated to the first processing path for processing is equal to the quantity of other tobacco product raw materials allocated to the second processing path for processing (i.e., the quantity of the tobacco product raw materials is evenly divided). For these 16 tobacco product raw materials, in the order of the main feature area from large to small, the first 8 tobacco product raw materials with larger main feature areas (i.e., larger mass change amounts and stronger flavor volatilization characteristics) are allocated to the roller line for processing, and the last 8 tobacco product raw materials with smaller main feature areas (i.e., smaller mass change amounts and weaker flavor volatilization characteristics) are allocated to the air flow line for processing.

[0124] Then, similarly, organize multiple formulators to conduct sensory evaluations on the single-component tobacco products made from each of the 16 tobacco product raw materials shown in Table 5 through the air flow line and the roller line respectively, and based on the results of the sensory evaluations, allocate the processing paths for each tobacco product raw material.

[0125] For the same single-component tobacco product, subtract the number of people who think the product obtained by processing through the air flow line is better from the number of people who think the product obtained by processing through the roller line is better, and obtain the data X1. If X1 is negative, record the data X2 as 1, indicating that the quality of the product processed by the roller line is better than that of the product processed by the air flow line; if X1 is positive, record the data X2 as 2, indicating that the quality of the product processed by the air flow line is better than that of the product processed by the roller line. The corresponding manual allocation results are shown in Table 6.

[0126] Table 6

[0127] As can be seen from the results shown in Table 6, the allocation methods of multiple formulators for the processing paths of these 16 tobacco product raw materials are basically the same as the results obtained by using the grouping processing technical solution proposed in the present disclosure. This indicates that for tobacco products with lower quality grades, the grouping processing technical solution proposed in the present disclosure can effectively replace the method of selecting the processing path based on the results of manual sensory evaluations, thereby eliminating the need to spend a lot of time organizing manual sensory evaluations and improving the efficiency of grouping processing. Moreover, compared with the manual sensory evaluation method, the grouping processing method of the present disclosure is more objective and accurate, avoiding the uncertainties brought by human subjective factors.

[0128] In summary, it can be seen that whether it is target tobacco products with higher quality grades or target tobacco products with lower quality grades, the grouping processing technical solution proposed in the present disclosure can perform efficient and reliable grouping processing on the tobacco product raw materials used to prepare the target tobacco products.
