Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing, and in particular to a cross-origin, multi-variety, multi-grade leaf threshing module homogenization feeding method and application thereof. Background Art

[0002] The improvement of modular formula processing level meets the raw material demand of cigarette brands with "big brand and big technology", but with the development of formula modules, cross-production area, multi-variety and multi-grade modules appear and their scale continues to increase, which increases the difficulty of tobacco leaf homogenization processing and feeding to a certain extent.

[0003] Currently, most redrying and processing companies use a homogenization processing model based on direct injection from a flat warehouse. This model tests the nicotine content of selected raw tobacco frame by frame, and based on the test results, classifies the framed tobacco into three categories: high, medium, and low. The classified materials are then added proportionally, achieving excellent homogenization results even with limited input materials. The main homogenization processing indicators, nicotine CV and moisture CV, both reach industry-leading levels. However, with the diversification of flue-cured tobacco varieties and the development of modular formulations in various producing areas in recent years, the number of modular formulation materials has increased. As a result, the direct injection homogenization processing model, which classifies each raw material into three categories based on nicotine content, requires far more leaf-laying and swinging stations than currently provided by threshing and redrying companies, and the resulting product has poor homogenization.

[0004] The current solution is for process personnel to combine and add materials based on their personal experience. This reliance on experience, lacking theoretical support, is significantly influenced by subjective factors, which impacts product quality and structure, and results in insufficient homogenization and refinement.

[0005] Therefore, how to improve product homogeneity by changing the feeding method has become an urgent problem to be solved. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a cross-origin, multi-variety, multi-grade leaf threshing module homogenization feeding method and its application. In the present invention, before feeding, the raw materials with a lower proportion in the formula are selected according to the blending priority for blending, which can greatly reduce the amount of feeding, effectively optimize the material quantity, improve the operability of homogenization processing feeding, and effectively reduce the coefficient of variation of nicotine and moisture in the product.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a cross-origin, multi-variety, and multi-grade threshing module homogenization feeding method, the method comprising classifying the raw materials in the formula according to tobacco growing region, variety, and grade, sorting the raw materials in the formula from highest to lowest quality, using raw materials greater than 30 as blending raw materials, selecting the blended raw materials according to blending priority, and uniformly blending them;

[0009] The blending priorities are:

[0010] A: Same tobacco growing area and variety, same grade;

[0011] B: same tobacco growing area and variety, adjacent grades;

[0012] C: Same tobacco growing area, different varieties, same grade;

[0013] D: Same tobacco growing area, different varieties, adjacent grades;

[0014] E: Different tobacco growing areas, same variety, same grade;

[0015] F: Different tobacco growing areas, same variety, adjacent grades;

[0016] G: Different tobacco growing areas and varieties, same grade;

[0017] H: different tobacco growing areas and varieties, adjacent grades;

[0018] Among them, A is the highest priority, the priorities decrease in sequence, and H is the lowest priority.

[0019] In the leaf threshing formula, the quantity proportion is small and the grade accounts for a small proportion, so accurate feeding is difficult, but the impact on the overall quality of the formula is small. Using the above-mentioned blending priority, raw materials with closer quality are selected for the raw materials with lower proportions in the formula, and they are mixed evenly first, which significantly improves the accuracy of feeding and further improves the homogeneity of production.

[0020] Preferably, the first-level tobacco growing areas include the southwestern tobacco growing areas, the southeastern tobacco growing areas, the middle and upper reaches of the Yangtze River growing areas, the Huanghuai tobacco growing areas and the northern tobacco growing areas.

[0021] In the present invention, since tobacco-producing areas are widely distributed, the ecological environment conditions for tobacco leaf production vary greatly, and the quality conditions and style characteristics of tobacco leaves in different producing areas vary greatly, the raw materials are divided according to different planting areas.

[0022] The secondary tobacco growing areas in the southwestern tobacco growing areas include the central Yunnan plateau flue-cured tobacco area, the southeastern Yunnan plateau and western Guizhou middle mountain and hilly flue-cured tobacco area, the western Yunnan plateau mountain flue-cured tobacco-burley tobacco-oriental tobacco area, the southern Yunnan and western Guangxi mountain and hilly flue-cured tobacco area, the northeastern Yunnan and northwestern Guizhou and southern Sichuan plateau mountain flue-cured tobacco area, the southwestern Sichuan mountain flue-cured tobacco area, the central Guizhou plateau mountain flue-cured tobacco area and the southeastern Guizhou low mountain and hilly flue-cured tobacco area.

[0023] Preferably, the secondary tobacco growing areas in the southeastern tobacco growing areas include the hilly and mountainous flue-cured tobacco areas in southern Hunan, northern Guangdong, and northeastern Guangxi, the hilly flue-cured tobacco areas in western Fujian, southern Jiangxi, and eastern Guangdong, or the hilly flue-cured tobacco areas in southern Anhui and northern Jiangxi.

[0024] Preferably, the secondary tobacco growing areas in the middle and upper reaches of the Yangtze River tobacco growing areas include the western Hunan mountain flue-cured tobacco area, the Chongqing-western Hubei-eastern Sichuan mountain flue-cured tobacco and burley tobacco area, the southern Shaanxi mountain and hilly flue-cured tobacco area and the northern Sichuan basin low mountain and hilly flue-cured tobacco and sun-cured tobacco area.

[0025] Preferably, the secondary tobacco growing areas in the Huanghuai tobacco growing area include the low mountain and hilly tobacco growing areas in central and southern Shandong, the hilly and mountainous tobacco growing areas in western Henan, the plain tobacco growing areas in central Henan, the hilly and terraced tobacco growing areas in the southern Henan and northern Hubei basins, the hilly and terraced tobacco growing areas in the eastern Henan and northern Anhui provinces, and the tableland tobacco growing areas in northern Weihai.

[0027] Preferably, the blending priority in the tobacco growing areas is that the secondary tobacco growing areas are greater than the primary growing areas.

[0028] In the present invention, when the blending raw material and the raw material to be blended are located in the same secondary tobacco planting area, they are preferably blended; when the blending raw material and the raw material to be blended are located in different secondary tobacco planting areas, the raw materials located in the same primary planting area are preferably blended. That is, raw materials with similar ecological environmental conditions and similar quality are selected as much as possible for blending.

[0029] Preferably, the varieties include any one of Honghua Dajinyuan, CB-1, Yunyan 87, Yunyan 97, Yunyan 116, Cuibi No. 1, Zhongyan 100 or NC89, or a combination of at least two of them.

[0030] Preferably, the adjacent levels are divided as follows:

[0031]

[0032]

[0033] The grading standards for each grade in the present invention are derived from the national standard GB2635-1992 (flue-cured tobacco).

[0034] Preferably, the blending priority among adjacent levels is that the adjacent levels in the same group are greater than the adjacent levels of appearance quality, the blending priority among adjacent levels in the same group is that level one is greater than level two, and the blending priority among adjacent levels of appearance quality is that level one is greater than level two, which is greater than level three.

[0036] Preferably, the maximum number of blending times of all raw materials in the formula is 1-2 times.

[0037] In a second aspect, the present invention provides an application of the cross-origin, multi-variety, multi-grade leaf threshing module homogenization feeding method described in the first aspect in tobacco leaf homogenization.

[0038] Compared with the prior art, the present invention has at least the following beneficial effects:

DETAILED DESCRIPTION

[0040] For the convenience of understanding the present invention, the present invention is given below with examples. It should be understood by those skilled in the art that the examples are only for the purpose of helping to understand the present invention and should not be regarded as specific limitations of the present invention.

[0041] Example 1

[0042] In the present invention, homogeneous feeding processing is carried out

[0043] In the present invention, 43,534.55 dan of raw tobacco, totaling 20 materials, was input into the Chuxiong Regional Processing Center of Jiangsu Zhongyan in 2023. After tobacco leaf sorting, the homogenization feeding system was optimized and further divided into 40 materials according to high, medium, and low nicotine levels after sorting, as shown in Table 1. Two feeding methods were used: conventional feeding mode and homogenization feeding method. The raw materials and proportions in this formula are shown in Table 2.

[0044] Table 1

[0045]

[0046]

[0047] Through the above content, we can know that: ① high nicotine Chuxiong C3L-B (raw material 1) accounts for 0.35%, and there is no priority A raw material mentioned above, so the high nicotine Chuxiong C4F-B (raw material 23) of the same planting area and variety and adjacent grade as priority B is selected for blending, and the mass ratio of the two is 1:7. After blending, it accounts for 2.83% of the module; similarly, medium nicotine Dali X2F-B (raw material 2), low nicotine Dali X2F-B (raw material 3), high nicotine Lijiang B1F-B (raw material 8), high nicotine Lijiang B3F-B (raw material 10), medium nicotine Chuxiong B1F-B (raw material 11), high nicotine Dali B3F-B (raw material 12), low nicotine Chuxiong C4F-B (raw material 13) and medium nicotine Lijiang B3F-B (raw material 14) are blended with adjacent grades of the same variety from the same planting area; ② low-nicotine Lijiang B1F-B (raw material 5) accounts for 1.26%, and there are no priority A, B, C, and D raw materials. Therefore, low-nicotine Chuxiong B1F-B (raw material 6) of the same grade and variety from different planting areas with priority E is selected for blending. The mass ratio of the two is 1:1, and the blended module accounts for 2.58%; similarly, medium-nicotine Lincang B2F (raw material 15) ③ high-nicotine Dali C4F-B (raw material 9) accounts for 1.39%, and there are no priority A, B, C, D, E, and F raw materials. Therefore, high-nicotine Lincang C4F (raw material 32) of the same grade and variety from different planting areas is selected. The mass ratio of the two is 1:2.34, and the blended module accounts for 4.64%.

[0049]

[0050]

[0051] Routine feeding T1 was performed according to Table 1, and homogenized feeding T2 was performed according to Table 2. After feeding, raw material processing was performed. Thirty samples of the finished product of each solution were taken for nicotine and moisture testing, and the coefficient of variation was calculated. The specific results are shown in Table 3.

[0052] Table 3

[0053] Feeding mode Nicotine coefficient of variation % Moisture coefficient of variation % T1 2.86 1.89 T2 2.43 1.72 Average in 2023 2.58 1.75

[0054] The results show that the nicotine variation coefficient is 2.41% when the optimized feeding mode is adopted, which is 0.41% lower than that of the conventional processing mode and 0.17% lower than the annual average value of the Chuxiong regional processing center; the moisture variation coefficient is 1.74%, which is 0.11% lower than that of the conventional processing mode and basically the same as the annual average.

[0055] The present invention significantly improves the accuracy of feeding by pre-blending raw materials with a lower proportion in the formula with raw materials of similar quality, reduces the feeding error of raw materials with a small proportion, thereby reducing the nicotine variation coefficient and moisture variation coefficient in the product and improving the homogeneity of the product.

[0056] Example 2

[0057] This embodiment performs stability testing

[0058] In this example, three batches of materials were added to the DCAKAHK module in Lincang, Yunnan, according to the formula in Table 1. The materials were blended and added according to the method in Table 2. After adding the materials, the raw materials were processed. Thirty samples were taken from each batch of finished products for nicotine and moisture testing, and the coefficient of variation was calculated. The specific results are shown in Table 4.

[0059] Table 4

[0060]

[0061]

[0062] The results of three repeated tests showed that the homogenization method of the present invention has high stability and repeatability, and can significantly improve the homogenization level of the test to obtain a homogenized product.

[0063] In summary, the present invention selects the raw materials with a lower proportion in the formula according to the blending priority before adding the raw materials, which can greatly reduce the amount of raw materials to be added, effectively optimize the amount of materials, improve the operability of the homogenization processing and feeding, effectively reduce the coefficient of variation of nicotine and moisture in the product, and effectively improve the homogenization level of the product.
