Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of tobacco processing, and particularly relates to a sorting and assembly method for grades including B3F, C4F, and X2F. Background Art
[0002] With the improvement of cigarette structure, the demand of industrial enterprises for middle-leaf tobacco and high-quality tobacco leaves has increased. There is a shortage of high-quality raw materials for key brands, and there are problems of "not enough to eat" and "not eating well". It is necessary to optimize the allocation of tobacco leaf resources through vertical formula and improve the utilization efficiency of raw materials. Threshing and redrying is a key link in the transformation of tobacco leaves from agricultural products to industrial raw materials, and has great potential in improving the utilization level of tobacco leaves. At present, although formula threshing has been fully promoted, there are problems such as insufficient vertical fluidity of tobacco leaf resources, room for improvement in the scientificity of assembly, and insufficient pertinence of matching and threshing, which restrict the further improvement of the utilization efficiency of tobacco leaves and the quality of cigarette products. Vertical formula assembly and threshing helps to solve these problems. By implementing vertical formula assembly, the utilization of tobacco leaf resources can be optimized, the raw material cost can be reduced, the waste of raw material resources and quality fluctuations can be reduced, so as to achieve cost reduction and efficiency increase in the tobacco industry and improve the overall economic benefits of the industry. At present, in the process of tobacco processing, there are situations such as inaccurate sorting and unreasonable assembly in the treatment of medium- and low-grade tobacco leaves such as B3F, C4F, and X2F, resulting in waste of tobacco leaf resources and unstable quality. Summary of the Invention
[0003] In order to avoid the deficiencies of the above-mentioned prior art, the present invention provides a sorting and assembly method for improving the usability of the vertical formula module of tobacco, which is an optimized sorting and vertical assembly threshing method for tobacco leaves of grades including B3F, C4F, and X2F, aiming to achieve the efficient utilization of medium- and low-grade tobacco leaves, reduce resource waste, improve the quality stability and industrial usability of tobacco leaf raw materials, and meet the market demand for high-quality tobacco products.
[0004] The present invention adopts the following technical solutions to achieve the above-mentioned invention objectives:
[0005] The sorting and assembly method for improving the usability of the vertical formula module of tobacco according to the present invention is characterized in that representative flue-cured tobacco leaves of B3F, C4F, X2F, and control C3F are selected for differential sorting, then chemical component analysis and screening are carried out, tobacco leaves with too large target dispersion are removed, and then sensory evaluation and assembly optimization are carried out, as well as formula module construction and verification, so as to achieve the purpose of replacing high-grade tobacco leaves with vertical formula assembly of medium- and low-grade tobacco leaves.
[0006] The sorting and assembly method for improving the usability of the vertical formula module of tobacco according to the present invention is characterized by including the following steps:
[0007] Step 1. Selection of tobacco leaf raw materials: Select flue-cured tobacco leaves of B3F, C4F, and X2F. Their production areas, varieties, and cultivation conditions are consistent and stable to ensure the relatively stable basic quality characteristics of the tobacco leaf raw materials. Select flue-cured tobacco leaves of C3F with the same production area and variety as the control. Conduct appearance quality inspections on the selected tobacco leaves. For the middle and lower leaves, focus on color, oil content, and texture; for the upper leaves, focus on maturity, structure, and texture.
[0008] Step 2. Chemical composition analysis and screening: Use a near-infrared instrument to detect the chemical compositions of flue-cured tobacco leaves of B3F, C4F, X2F, and the control C3F, and obtain the contents of reducing sugar, nicotine, chlorine, and potassium. According to the requirements of cigarette products for the coordination of chemical compositions, set the appropriate ranges for each chemical composition, and screen out tobacco leaf batches whose chemical compositions are close to or can complement each other to reach the target C3F range through data analysis.
[0009] Step 3. Sensory evaluation and formulation optimization: Organize professional sensory evaluation personnel to conduct sensory evaluations on the B3F, C4F, X2F, and C3F flue-cured tobacco leaves after chemical composition screening. According to the sensory evaluation results, use the method of gradual adjustment for formulation optimization. The formulation optimization is as follows: First, determine a basic formulation ratio, then fine-tune the ratios of tobacco leaves of each grade, observe the changes in sensory quality, and determine the best formulation ratio.
[0010] Step 4. Construction and verification of the formulation module: According to the determined best formulation ratio, thresh and redry the B3F, C4F, and X2F flue-cured tobacco leaves into the formulation module BCX, and apply it to the actual cigarette formulation to replace the original part of C3F. Verify and adjust the actual application effect of the formulation module through small-batch trial production and further sensory quality inspection and flue gas chemical composition detection. Ensure that in large-scale production applications, the quality indicators of cigarette products are stable, the style characteristics remain consistent, and meet the sensory needs of consumers and product quality standards.
[0011] The characteristics of the sorting and formulation method for improving the usability of the tobacco vertical formulation module of the present invention also lie in that the requirements for selecting tobacco leaf raw materials in Step 1 are as follows: For B3F, the requirements for leaf selection are maturity from mature to fully ripe, structure slightly dense to loose, soft to the touch, moderate texture, slightly thin to slightly thick; for C4F, the requirements for leaf selection are color bright yellow to orange-yellow, overall uniform leaf color, oil content slightly present or above, with an oily feeling, texture slightly thin to medium; for X2F, the requirements for leaf selection are color bright yellow to light orange-yellow, with a shiny feeling, oil content slightly present or above, with an oily feeling, texture slightly thin or above, without a floating feeling; for C3F, leaf selection is general selection, just remove mildew and impurities.
[0012] The characteristics of the sorting and formulation method for improving the usability of the tobacco vertical formulation module of the present invention also lie in that the appropriate ranges for setting each chemical composition in Step 2 are as follows:
[0013] Grade Reducing sugar % Nicotine % Sugar - nicotine ratio Potassium % Chlorine % B3F 16-25 2.5-3.5 6-10 ≥1.8 0.2-0.6 C4F 18-28 1.8-2.7 8-14 ≥1.8 0.2-0.6 X2F 18-28 1.5-2.2 10-16 ≥1.8 0.2-0.6 C3F 18-30 1.8-2.8 8-12 ≥1.8 0.2-0.6
[0014] The characteristics of the sorting and matching method for improving the usability of the tobacco vertical formulation module of the present invention also lie in that the sensory evaluation indexes in step 3 include aroma quantity, aroma quality, foreign odor, irritation and aftertaste, and a 9-point scoring standard is adopted for evaluation.
[0015] The characteristics of the sorting and matching method for improving the usability of the tobacco vertical formulation module of the present invention also lie in that in step 3, the basic matching ratio of B3F:C4F:X2F is set to 2:6:2.
[0016] The characteristics of the sorting and matching method for improving the usability of the tobacco vertical formulation module of the present invention also lie in that the number of cigarette products in the trial production in step 4 is determined according to the actual production scale and detection requirements.
[0017] Compared with the prior art, the beneficial effects of the present invention are embodied in:
[0018] 1. By scientifically screening and reasonably matching B3F, C4F and X2F flue-cured tobacco, the present invention effectively solves the problems that may be brought by the unstable supply and quality of C3F tobacco leaves, and provides a stable and reliable tobacco leaf formulation alternative plan for cigarette production.
[0019] 2. The present invention makes full use of the resource advantages of different grades of flue-cured tobacco. Through optimized matching, it can not only maintain the original style and quality of cigarette products, but also may further improve the aroma richness and taste coordination of products in some aspects.

Specific Embodiments
[0021] The following details the embodiments of the present invention. These embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments.
[0022] In this embodiment, the sorting and matching method for improving the usability of the tobacco vertical formulation module is to select representative B3F, C4F, X2F and control C3F flue-cured tobacco leaves for differential sorting, then conduct chemical component analysis and screening, eliminate tobacco leaves with too large target dispersion, and then conduct sensory evaluation and matching optimization, as well as formulation module construction and verification, so as to achieve the purpose of replacing high-grade tobacco leaves with vertical formulation matching of medium- and low-grade tobacco leaves.
[0023] The sorting and matching method in this embodiment includes the following steps:
[0024] Step 1, Selection of tobacco leaf raw materials: Select B3F, C4F, and X2F flue-cured tobacco leaves. Their production areas, varieties, and cultivation conditions are consistent and stable to ensure the relative stability of the basic quality characteristics of the tobacco leaf raw materials. Select C3F flue-cured tobacco leaves with the same production area and variety as the control. Conduct appearance quality inspections on the selected tobacco leaves. For the middle and lower leaves, focus on color, oil content, and identity. For the upper leaves, focus on maturity, structure, and identity.
[0025] In specific implementation, the requirements for the selection of tobacco leaf raw materials are as follows: For B3F leaf selection, the maturity requirement is from mature to fully mature, the structure is slightly dense to loose, it feels soft to the touch, the identity is moderate, and it is slightly thin to slightly thick; for C4F leaf selection, the color requirement is light yellow to orange-yellow, the overall leaf color is uniform, the oil content is slightly oily or above, there is an oily feeling, and the identity is slightly thin to medium; for X2F leaf selection, the color requirement is light yellow to light orange-yellow, there is a bright feeling, the oil content is slightly oily or above, there is an oily feeling, the identity is slightly thin or above, and there is no floating feeling; for C3F leaf selection, it is general selection, and only mildewed and miscellaneous leaves need to be removed.
[0026] Step 2, Chemical composition analysis and screening: Use a near-infrared instrument or a continuous flow analyzer to conduct chemical composition tests on B3F, C4F, X2F flue-cured tobacco leaves and the control C3F flue-cured tobacco leaves to obtain the contents of reducing sugar, nicotine, chlorine, and potassium. According to the requirements of cigarette products for the coordination of chemical compositions, set the appropriate ranges for each chemical composition, and screen out tobacco leaf batches whose chemical compositions are close to or can complement each other to reach the target C3F range through data analysis. For example, for the contents of total sugar and reducing sugar, screen out combinations of B3F, C4F, and X2F tobacco leaves that are similar to the target C3F chemical composition within a certain range; for the nicotine content, select tobacco leaf samples that can achieve the appropriate strength and irritation requirements through reasonable matching.
[0027] Set the appropriate ranges for each chemical composition as shown in Table 1:
[0028] Table 1 Appropriate ranges of chemical compositions
[0029] Grade Reducing sugar % Nicotine % Sugar - nicotine ratio Potassium % Chlorine % B3F 16-25 2.5-3.5 6-10 ≥1.8 0.2-0.6 C4F 18-28 1.8-2.7 8-14 ≥1.8 0.2-0.6 X2F 18-28 1.5-2.2 10-16 ≥1.8 0.2-0.6 C3F 18-30 1.8-2.8 8-12 ≥1.8 0.2-0.6
[0030] Step 3, Sensory Evaluation and Blending Optimization: Organize professional sensory evaluation personnel to conduct sensory evaluation on the B3F, C4F, X2F, and C3F flue-cured tobacco leaves after chemical composition screening; according to the sensory evaluation results, use the method of gradual adjustment for blending optimization; the blending optimization is as follows: First, determine a basic blending ratio, which can be a basic blending ratio of B3F:C4F:X2F of 2:6:2, and then fine-tune the ratio of each grade of tobacco leaves, observe the changes in sensory quality, and determine the optimal blending ratio; for example, make cigarette tobacco samples by mixing B3F, C4F, and X2F tobacco leaves in different ratios, conduct sensory evaluation, compare and analyze the aroma styles and taste comfort under different blending schemes, and finally determine the optimal blending ratio that is closest to C3F in terms of aroma, taste, etc. and has excellent comprehensive sensory quality. The sensory evaluation indicators of sensory evaluation include aroma quantity, aroma quality, off-flavors, irritation, and aftertaste, and a 9-point scoring standard is used for evaluation.
[0031] Step 4, Formulation Module Construction and Verification: According to the determined optimal blending ratio, thresh and redry the B3F, C4F, and X2F flue-cured tobacco leaves into the formulation module BCX, and apply it to the actual cigarette formulation to replace the original part of C3F; verify and adjust the actual application effect of the formulation module through small-batch trial production and further sensory quality inspection and flue gas chemical composition detection; ensure that in large-scale production applications, the quality indicators of cigarette products are stable, the style characteristics remain consistent, and meet the sensory needs of consumers and product quality standards; the number of cigarette products for trial production is determined according to the actual production scale and detection requirements.
[0032] Example 1:
[0033] Select 5000 dan of B3F, C4F, X2F, and C3F tobacco leaves produced in Huidong or Huili from the tobacco leaves allocated by the applicant in Liangshan, Sichuan in 2022 as test samples. The test variety is Honghuadajinyuan, and industrial secondary sorting is carried out respectively. The leaf selection requirements for B3F are better maturity, relatively loose and soft leaf tissue structure, medium identity, slightly thin to medium, brighter color, and consistent leaf color. The selected tobacco leaves are marked as B3F-1; the leaf selection requirements for C4F are yellow to golden yellow in color, uniform and consistent leaf color, good oil content, a sense of oiliness, slightly thin to medium identity, and a fleshy feeling when touched by hand. The selected tobacco leaves are marked as C4F-1; the leaf selection requirements for X2F are yellow to golden yellow in color, bright and consistent leaf color, good oil content, a sense of oiliness, identity slightly thin and above, and a substance when touched by hand, not floating. The selected tobacco leaves are marked as X2F-1; C3F is selected generally, removing blue mold and impurities, and the selected code remains C3F. After industrial sorting according to the above requirements, 3100 dan of B3F-1 are selected, accounting for 62%; 3250 dan of C4F-1 are selected, accounting for 65%; 2400 dan of X2F-1 are selected, accounting for 48%; and 4900 dan of C3F are selected, accounting for 98%.
[0034] The selected tobacco leaves were tested for their conventional chemical components using a near-infrared instrument. For B3F-1, C4F-1, and X2F-1, samples were taken once per frame (500 kg), and for C3F, samples were taken once every 2 frames. Each sample weighed 1 kg, and the 5-point sampling method was used. The test results showed that in B3F, 8 frames had excessive nicotine content (above 3.7%), 2 frames had excessive sugar-to-alkaloid ratio (above 14), and 1 frame had an imbalanced potassium-to-chlorine ratio (potassium 1.2%, chlorine 0.8%, potassium-to-chlorine ratio 1.5), not meeting the target requirements, so they were discarded; in C4F, 2 frames had excessive nicotine content (above 3.0%), 4 frames had excessive reducing sugar content and sugar-to-alkaloid ratio (reducing sugar above 38%, sugar-to-alkaloid ratio above 18), so they were discarded; in X2F, 8 frames had low nicotine content (below 1.2%) or excessive sugar-to-alkaloid ratio (above 18), so they were discarded. In C3F, 4 frames had excessive nicotine content (above 3.2%), 6 frames had excessive sugar-to-alkaloid ratio (above 16), so they were discarded. After removing the samples that did not meet the target requirements, the statistical results of the chemical components of the remaining samples for each grade are shown in Tables 2, 3, 4, and 5:
[0035] Table 2 Statistical Table of Chemical Components of B3F-1 Grade
[0036] Index Reducing sugar % Nicotine % Potassium % Chlorine % Average value 20.42 3.04 2.25 0.36 Standard deviation 2.45 0.23 0.12 0.13 Coefficient of variation 12.02 7.42 5.34 36.78 Maximum value 25.88 3.46 2.58 0.66 Minimum value 15.56 2.56 2.00 0.19

[0043] It can be seen from the above tables that after industrial secondary sorting as required and removing particularly abnormal samples, the chemical component contents of each grade are basically within the appropriate target requirements. At the same time, the chemical components of the C4F-1 grade are relatively close to those of the control sample C3F. Therefore, C4F-1 should be used as the main grade in the subsequent blending design.
[0044] A part of the samples for chemical testing taken above was separated. After mixing each frame of each grade evenly, they were used as sensory smoking samples. Seven professional sensory smoking personnel were organized to conduct sensory smoking evaluations on the mixed monomer samples of B3F-1, C4F-1, X2F-1, and C3F first. The evaluation results are shown in Table 6:
[0045] Table 6 Sensory Smoking Evaluation Results of Each Monomer Grade
[0046]
[0047] Based on C4F-1, referring to the chemical compositions and sensory evaluations of each grade, B3F-1 and X2F-1 were added in different proportions for the blending experiment, and a total of three blending schemes, BCX-1, BCX-2, and BCX-3, were designed as follows:
[0048] Blending scheme 1 of BCX-1: B3F-1:C4F-1:X2F-1 = 2:6:2;
[0049] Blending scheme 2 of BCX-2: B3F-1:C4F-1:X2F-1 = 1:4:1;
[0050] Blending scheme 3 of BCX-3: B3F-1:C4F-1:X2F-1 = 2:4:1;
[0051] The tobacco cut samples of each blending scheme were made and subjected to sensory evaluation, and the comparison evaluation was carried out with reference to C3F;
[0052] The evaluation results are shown in Table 7:
[0053] Table 7 Sensory evaluation results of each blending grade
[0054]
[0055] By comparing the sensory evaluation results under different blending schemes, it was found that blending scheme 3 was the closest to C3F in terms of aroma quantity, concentration, off-flavors, and taste, and the comprehensive sensory quality was excellent. Therefore, the optimal blending ratio was determined as:
[0056] B3F-1:C4F-1:X2F-1 = 2:4:1
[0057] According to the determined optimal blending ratio, B3F-1, C4F-1, and X2F-1 tobacco leaves were proportionally fed and threshed and redried to construct a formula module, and the strip tobacco module BCX was obtained, with a quantity of 3,364 dan (the output rate was 62%). The quantity of strip tobacco after threshing and redrying of C3F was 3,024 dan. The strip tobacco module BCX and C3F strip tobacco were placed in the same aging warehouse for two years and then applied to the actual cigarette formula. For the comparison and verification (C3F strip tobacco was the replacement in the normal year of a specific first-class leaf group formula), 30 cases of cigarettes were produced in small batches. The sensory evaluation test and routine chemical composition detection of the aged strip tobacco were carried out, and the sensory quality test and smoke chemical composition detection of the trial-produced cigarette products were carried out. The results are as follows in the table:
[0058] Table 8 Statistical table of chemical compositions of aged strip tobacco
[0059]
[0060] Table 9 Sensory evaluation results of aged strip tobacco
[0061]
[0062] Table 10 Sensory Evaluation Results of Trial-Produced Finished Cigarettes
[0063]
[0064] Table 11 Detection Results of Flue Gas Chemical Components of Trial-Produced Finished Cigarettes
[0065] Trial - produced cigarette name Tar content / mg Nicotine content in mainstream smoke / mg Carbon monoxide content in mainstream smoke / mg No.1 (Control C3F accounts for 4% in the leaf blend) 10.0 1.0 10.0 No.2 (BCX module accounts for 4% in the leaf blend) 10.0 1.0 10.0
[0066] As can be seen from Tables 8 - 11, the quality consistency of the cased tobacco leaves after aging is relatively high with that of C3F cased tobacco leaves. The quality indicators of the trial-produced cigarettes produced by replacing C3F with BCX modules are stable, the style characteristics remain consistent, and there are no significant differences in the sensory quality and flue gas indicators between the cigarettes produced using BCX modules and those produced using C3F tobacco leaves. It can meet the product quality standards and the sensory needs of consumers, and can be mass-produced for replacement.
[0067] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
