Technical Field

[0001] The invention relates to the technical field of tobacco leaf raw material blending and beating processing, and in particular to a method for manufacturing an upper six-piece tobacco leaf raw material module. Background Art

[0002] The top six tobacco leaves refer to the 4-6 tobacco leaves on the top of the tobacco plant grown in high-quality tobacco areas. Due to the small scale and unstable quality of the single grade of the top six tobacco leaves, in actual applications, they cannot truly meet the cigarette industry's requirements for the homogeneity of raw material quality and the batch production of the total amount.

[0003] Formula threshing is a common raw material processing model in the industry. It is to combine multiple single-grade, small-scale tobacco leaves into a larger modular unit for threshing. This solves the problem of the small number of single-grade tobacco leaves in the procurement process. At the same time, it also greatly ensures that the tobacco raw materials have consistent quality levels, coordinated internal chemical compositions, and a certain scale of usage demand.

[0004] Therefore, the industry is exploring a solution that meets the demand for high-quality tobacco raw materials and can provide targeted design of batch formula for leaf beating in the leaf beating and re-drying stage, especially to solve the obvious gap between the quality of commercial tobacco purchase grades and processing recognition. Summary of the invention

[0005] In view of the above, the present invention aims to provide a method for manufacturing a six-piece tobacco leaf raw material module to solve the above-mentioned technical problems.

[0006] The technical solution adopted by the present invention is as follows:

[0011] Using the sorted samples and the quality indexes, evaluating whether the quality of the six tobacco leaves meets the established requirements;

[0012] The upper six tobacco leaves that meet the quality standards are used for threshing and re-roasting to obtain the upper six tobacco leaves raw material module finished product.

[0015] The moisture content of leaves of each grade is controlled at 16-18%, and the number of leaves of each grade selected is not less than 50 pieces.

[0016] In at least one possible implementation, the evaluating the quality of the six tobacco leaves includes:

[0017] Tobacco leaves from different production areas and grades are sampled in the same proportion and then stemmed and shredded;

BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below with reference to the accompanying drawings, in which:

[0028] Figure 1 A schematic diagram of a method for producing an upper six-leaf tobacco leaf raw material module provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0030] The present invention proposes an embodiment of a method for manufacturing a six-piece tobacco leaf raw material module. Specifically, Figure 1 shown, including:

[0031] Step S1, in the selected upper six tobacco leaf producing area, obtaining an initial upper six tobacco leaf module formula according to the established production requirements;

[0032] This process mainly involves screening the production areas and areas suitable for producing the upper six leaves of tobacco raw materials, and obtaining the initial combination of the upper six leaves of tobacco modules according to the upper six leaves production technology, thereby obtaining parameters such as the original grade (original tobacco grade). The information content of the upper six leaves of tobacco module formula may include: year, origin, grade, quantity, leaf ratio, tobacco grade identification, leaf threshing and re-roasting processing requirements, etc.

[0033] Specifically, regarding the determination of the plots in the upper six production areas, we can mainly choose plots with better ecological and environmental conditions and a large area, which is convenient for management and implementation of production technology; secondly, we can further consider the convenience of irrigation and flood control, and the facilities must be complete and have medium fertility, and the chlorine content of the soil must be strictly controlled. For example, under a certain organic matter content in irrigation water, the organic matter content of the soil can be enriched to more than 13 mg / kg; in addition, crop rotation and good crop rate of tobacco fields can also be used as selection factors, such as giving priority to contiguous tobacco fields that have been cropped for less than three years.

[0034] The upper six leaves production technology mainly refers to the production of tobacco raw materials by harvesting the upper 4 to 6 leaves of tobacco leaves at maturity and delaying them for 7 to 10 days to bake them all at once.

[0035] Reference example: Taking the data of a redrying plant in 2023 as an example, the initial module assembly was carried out for 8692.5 dan of six-piece tobacco leaf raw materials allocated to 9 tobacco stations in Xuchang Xiangxian, Yuzhou and Pingdingshan Jiaxian, as shown in Table 1 for details.

[0036] Table 1

[0037]

[0038] Step S2, determining the quality indexes of the six tobacco leaves, wherein the quality indexes at least include: appearance quality, physical indexes, style characteristics, sensory indexes and chemical indexes;

[0039] Specifically, (1) the requirements for appearance quality can be: color is orange-dark yellow, texture is medium-slightly thick, leaf structure is loose-loose, maturity is mature, oil content is present, gloss is strong, color is strong, and elasticity is good. The specific evaluation can be carried out according to established standards, such as GB2635; (2) the requirements for physical indicators can be: single leaf weight is 18-25g, leaf length is 60-75cm; (3) the requirements for style characteristics can be: roasted sweet aroma, prominent nutty aroma, obvious burnt sweet aroma, and rich sweet aroma. The specific evaluation can be carried out according to established standards, such as YC / T530; (4) the requirements for sensory indicators can be: the smoke is fluffy, uniform and delicate, the skeleton is strong, the throat is smooth, and the fragrance lasts for a long time. The evaluation index can be: The standard aroma has good quality, sufficient aroma, strong to strong concentration, strong kick, slight to mild impurities, and comfortable to comfortable aftertaste. (5) The requirements for chemical indicators can be: total alkaloids 3.2±0.5%, total nitrogen 2.1-2.5%, total sugar 20±2%, reducing sugar 18±2%, total sugar to reducing sugar ratio ≥0.9, protein 7-9%, starch ≤4%, potassium content ≥1.6%, chlorine content ≤0.6%. The specific evaluation can be carried out according to established standards, such as reducing sugar and total sugar (YC / T159), nicotine (YC / T160), total nitrogen (YC / T161), potassium content (YC / T217), chlorine content (YC / T162) and other industry standards.

[0040] Step S3, sorting the upper six tobacco leaves according to the quality index and preparing the sorted samples of the upper six tobacco leaves raw materials;

[0041] For example, but not limited to, according to the ecological conditions and production technology of the production area of ​​the year, according to the usage quality of cigarettes at different price points and the appearance indicators in the aforementioned quality indicators, the six tobacco leaf raw material sorting samples can be produced, and when carrying out the sorting of the six tobacco leaf modules, it also includes defining the sorting purity tolerance and naming the six tobacco leaf modules after sorting.

[0042] First, the preparation of the six sorting samples specifically includes:

[0043] (1) Classification of sorted samples: According to the place of origin, they are divided into the upper six pieces of first-level module samples, namely Class A, which can be understood as meeting the quality requirements for the use of high-priced cigarettes; the second-level module samples, namely Class B, which can be understood as meeting the quality requirements for the use of Class II cigarettes; the third-level module samples, namely Class C, which can be understood as meeting the quality requirements for the use of Class III cigarettes.

[0044] (2) The sorting samples shall be prepared in accordance with at least the following requirements: the moisture content shall be controlled at 16%-18%, the quality shall be clearly highlighted and include the upper and lower limits of the grade, thereby reflecting the corresponding purity tolerance, and the quality factors closely related to the position, color and overall quality shall be relatively consistent; in addition, it may be required that the number of leaves of each grade shall not be less than 50 leaves. As mentioned above, these leaves need to reflect the main grade, as well as the upper and lower limits of the grade and inclusiveness.

[0045] Secondly, the aforementioned defined sorting purity tolerance includes: when classifying the upper six pieces of first-level module samples and second-level module samples, these two categories should not contain lower smoke; and the proportion of middle smoke contained in the first-level module samples is less than 15%, and the proportion of middle smoke contained in the second-level and third-level module samples is less than 20%.

[0046] Thirdly, regarding the naming method, the following example is provided for reference: tobacco year + tobacco raw material origin + tobacco module grade.

[0047] Combined with the previous example: using the appearance indicators in the sorting technical requirements, select leaves according to the three categories of ABC, see Table 2.

[0048] Table 2

[0049]

[0050] Step S4: using the sorted samples and the quality indexes, evaluating whether the quality of the six tobacco leaf modules meets the established requirements;

[0051] It can be pointed out here that because the tobacco module is obtained by combining raw materials of multiple grades, it is necessary to ensure the representativeness of the evaluation sampling, especially when evaluating the intrinsic quality indicators mentioned above such as chemical composition, style characteristics and sensory quality, the following specific implementation ideas can be adopted: first, tobacco leaves from different production areas and different grades are sampled in the same proportion and quantity and stemmed and shredded, and each grade of tobacco leaves is weighed separately and module proportioned to ensure that each batch of tobacco leaves can be accurately blended in proportion; secondly, the various tobacco shreds to be blended are evenly divided into several portions, and then blended accordingly to increase the probability of contact between the various tobacco shreds, thereby improving the uniformity of mixing; in addition, each grade of tobacco raw materials is repeatedly mixed at least three times to ensure uniformity.

[0052] In addition, it should be noted that if the evaluation results obtained in this step indicate that the quality does not meet the standards, the production area, quantity, benchmark samples, etc. of the upper six leaves can be adjusted and the combination can be re-selected and evaluated again, with the goal of making the quality of the upper six tobacco leaf modules meet the standards.

[0053] Reference example of module evaluation after sorting:

[0054] (1) Chemical composition evaluation The chemical indicators of the 2023 Xuchang B1FJ module were evaluated to meet the expected requirements: total alkaloids 3.2±0.5%, total nitrogen 2.1-2.5%, total sugar 20±2%, reducing sugar 18±2%, total sugar to reducing sugar ratio ≥0.9, protein 7-9%, starch ≤4%, potassium content ≥1.6%, chlorine content ≤0.6%. See Table 3 below.

[0055] Table 3

[0056]

[0057] (2) Style characteristics and sensory quality evaluation

[0058] The style characteristics are evaluated according to YC / T530: roasted sweet aroma, prominent nutty aroma, obvious burnt sweet aroma, rich sweet aroma, meeting the expected requirements of the upper six pieces.

[0059] The sensory quality evaluation indicators include aroma quality, aroma volume, concentration, softness, aftertaste, miscellaneous smell, irritation and strength. In the specific implementation, 11 professional smokers conducted sensory quality evaluation according to "YC / T138-1988•Sensory Evaluation Method for Tobacco and Tobacco Products". The evaluation of each sensory index project is based on a 9-point system. The total score of the sensory quality evaluation is the sum of the actual scores of each item multiplied by the weight.

[0060] The calculation formula for the total score of sensory quality evaluation is:

[0061] T=(A+B)×2.0+(C+D)×1.5+E+F+G+H, where T is the total score of sensory quality evaluation, A is the aroma quality score, B is the aroma quantity score, C is the concentration score, D is the softness score, E is the aftertaste score, F is the offal score, G is the irritation score, and H is the strength score. The sensory quality evaluation results are shown in Table 4.

[0062] Table 4

[0063]

[0064] As can be seen from Table 4, the sensory evaluation is that the burnt-sweet aroma is prominent, the skeleton is strong, it enters the throat smoothly, and the fragrance lasts for a long time. The evaluation indicators are good aroma quality, sufficient aroma, strong concentration, strong strength, light impurities, less irritation, and a comfortable aftertaste.

[0065] The above evaluation results show that according to the upper six quality factors, from the production area, industrial sorting to the internal quality evaluation, the needs of cigarette formulation are met, and the expected design requirements of the upper six tobacco leaf raw material module are achieved: the leaf structure is loose, the color is good, the oil content is high, the chroma is strong, the caramelized sweet aroma is prominent, the aroma volume is increased, the impurities and irritation are reduced, the aroma is full and round, the taste is comfortable and the aftertaste is pure.

[0066] Step S5, using the top six tobacco leaves that meet the quality standards to carry out leaf threshing and re-roasting to obtain the top six tobacco leaves raw material module finished product.

[0067] In actual operation, the base of the tobacco leaf can be placed as a reference, and the leaf base can be removed by cutting it upward from the bottom of the petiole at a predetermined length (such as 19±1cm). After marking the cut tobacco leaf parts, they are sent to the threshing and re-roasting stage. After the threshing and re-roasting process, the upper six pieces of raw material finished products are formed.

[0068] In summary, the main design concept of the present invention is to classify and grade according to the production area according to the quality requirements such as the brand style characteristics of cigarettes. After careful selection and quality control, the upper six tobacco leaves from different origins are mixed and matched in a specific proportion through the production of the upper six tobacco leaf modules, so as to facilitate large-scale production and flexible adjustment, and improve production efficiency and product quality consistency. Specifically including: screening production area plots suitable for the production technical conditions of the upper six leaves, pre-setting the quality factors required for the upper six leaves and formulating a leaf selection plan, preparing the upper six leaves of sorted tobacco leaf samples based on the above conditions, using the samples to evaluate the module formula, and for the upper six leaves of tobacco raw materials that meet the expected requirements, the upper six leaves of raw materials are processed by beating and re-roasting to form the finished products. The present invention can achieve the batch requirements of the homogeneity and total amount of the upper six leaves of tobacco raw materials, thereby significantly improving the matching degree between the raw materials and the cigarette formula.

In addition, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist.
