Description

Technical Field

[0001] This invention relates to the technical field of tobacco processing, and more specifically, to a design method for a tobacco leaf-slicing application module for leaf re-drying. Background Technology

[0002] The high-quality supply of tobacco leaves is undoubtedly the cornerstone for ensuring the final quality of cigarette products. From growth in the fields to final processing into cigarettes, every step is closely linked, jointly shaping the superior quality of cigarette products. In this process, threshing and re-drying, as a crucial link between the upstream and downstream processes, is not only a bridge connecting tobacco industrial production and the commercial market, but also the first step for industrial enterprises to strictly control the quality of tobacco raw materials.

[0003] However, the sensory quality of existing re-dried tobacco leaves has a low degree of consistency with the modular formula design, resulting in unstable supply of cigarette formulas. Therefore, it is of great significance to improve the sensory quality of finished tobacco leaves to ensure a high degree of consistency with the modular formula design, thereby ensuring a high-quality supply of raw materials, effectively solving the problem of sensory quality and consistency with the modular formula design of re-dried tobacco leaves, and providing a solid guarantee for the stable formula of cigarette products. Summary of the Invention

[0004] This invention provides a modular design method for tobacco slices produced by leaf re-drying, which solves the problem of low conformity between the sensory quality of existing finished tobacco slices and the modular formula design. It can improve the sensory quality of finished tobacco slices, ensure a high degree of consistency with the modular formula design, and provide a solid guarantee for the stable formula of cigarette products.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for designing a modular application for tobacco leaf processing and re-drying includes:

[0007] The module acquires the grade of tobacco leaves to be processed and detects the stem content μ, moisture content α, and sand content β of the tobacco leaves to be processed.

[0008] Based on formula ratio plan A, and combined with the tobacco leaf moisture content α, stem content μ, sand content β of the tobacco leaves to be added in the plan A, and the tobacco leaf moisture content γ of the module design, the formula ratio is uniformly converted into standard moisture, and the stem content and sand content are converted. Then, the formula ratio is recalculated to form conversion formula module plan B.

[0009] Based on the small-batch processing of formula module plan B, evaluate the quality difference between the cured tobacco and formula module plan B, and adjust the relevant parameters until the quality of the cured tobacco is the same as that of formula module plan B.

[0010] According to the formula module plan B, the leaves are processed by re-drying after adjustment of the parameters.

[0011] Preferred options also include:

[0012] Based on the formula ratio and the actual weight of the raw materials, the maximum scale of the module is calculated using the "weakest link" principle, or the remaining tobacco leaves are applied to other modules according to their quality and compatibility, based on the scale required by the product positioning module.

[0013] Preferably, the conversion of formula ratio plan A into formula module plan B includes:

[0014] According to the formula: = Calculate the weight N of a single grade corresponding to formula module plan B, where M is the weight of a single grade involved in formula ratio plan A.

[0015] Preferred options also include:

[0016] The design module pre-plans for tobacco leaf processing involves first brushing the front and back of the single-grade sample, according to the proportions of the formula module, 5-8 times each to remove tobacco dust, then shredding the sample, and finally placing the sample in a constant temperature and humidity environment for more than 48 hours, with a temperature of 22±2℃ and a humidity of 65±5%.

[0017] Preferably, the step of performing leaf re-drying processing according to the adjusted parameter settings in formula module plan B includes:

[0018] The blending and leaf spreading table is strictly operated in accordance with the formula module plan B. When switching between blending cabinets, it is ensured that the tobacco leaves in each cabinet are complete formulas. The process processing parameters are controlled with the corresponding values ​​of the small batch processing records in formula module plan B as the center value. The moisture content of the tobacco leaves is controlled to ±0.5 percentage points of the center value, and the temperature is controlled to ±3℃ of the center value.

[0019] Preferred options also include:

[0020] Take samples of the finished tobacco leaves every 2 hours and compare their sensory quality with the module formula design. If there are any differences in quality, promptly identify the cause and make targeted adjustments.

[0021] Preferably, the adjustment of the relevant parameters includes:

[0022] The parameters are initially set based on the physical properties of the raw materials, including shear force, tensile strength, hygroscopicity, and thickness.

[0023] The temperature and humidity settings are based on the degree of influence of temperature and humidity on the sensory quality of tobacco raw materials.

[0024] Preferably, adjusting the relevant parameters further includes:

[0025] After the first rinsing, the material temperature is 53±3℃ and the material moisture content is 16.2±0.5%. After the second rinsing, the material temperature is 56±3℃ and the material moisture content is 16.7±0.5%. The temperature of the highest drying zone of the re-drying equipment is 69±3℃.

[0026] Preferred options also include:

[0027] We continuously refine the information on the physical properties of single-grade raw materials and the impact of temperature and humidity on sensory quality by year and production location, and establish the relationship with processing parameters to form a database, providing a basis for setting subsequent processing parameters.

[0028] Preferred options also include:

[0029] The design module includes a tobacco leaf sampling plan, which involves sampling raw tobacco samples or selected samples at different grades, and combining the samples with the actual situation of tobacco leaf quality inspection.

[0030] This invention provides a modular design method for sliced ​​tobacco products using a leaf-pounding and re-drying process. The method involves converting a pre-planned formula ratio into a pre-planned formula module, and then processing in small batches according to this module. Relevant parameters are adjusted based on quality variations, and the leaf-pounding and re-drying process is then performed according to the adjusted parameter settings within the pre-planned formula module. This addresses the problem of low consistency between the sensory quality of existing finished leaf-pounded and re-dryed tobacco products and the modular formula design. It improves the sensory quality of the finished tobacco products, ensuring a high degree of consistency with the modular formula design and providing a solid guarantee for stable cigarette product formulations. Attached Figure Description

[0031] To more clearly illustrate the specific embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below.

[0032] Figure 1 This is a schematic diagram of a tobacco leaf re-drying module design method for tobacco leaf separation application modules provided by the present invention. Detailed Implementation

[0033] To enable those skilled in the art to better understand the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0034] To address the problem of low consistency between the sensory quality of currently produced re-dried tobacco sheets and the modular formula design, this invention provides a modular design method for re-dried tobacco sheets, which solves the problem of low consistency between the sensory quality of existing re-dried tobacco sheets and the modular formula design. This method can improve the sensory quality of finished tobacco sheets, ensure a high degree of consistency with the modular formula design, and provide a solid guarantee for the stable formulation of cigarette products.

[0035] like Figure 1 As shown, a method for designing a tobacco leaf sorting application module for leaf re-drying includes:

[0036] S1: Obtain the grade of tobacco leaves to be processed corresponding to the module, and detect the stem content μ, moisture content α, and sand content β of the tobacco leaves to be processed.

[0037] S2: Based on formula ratio plan A, and combined with the tobacco leaf moisture content α, stem content μ, sand content β of the grade of tobacco leaves to be added involved in plan A, and the tobacco leaf moisture content γ designed by the module, the formula ratio is uniformly converted into standard moisture, and the stem content and sand content are converted. Then, the formula ratio is recalculated to form conversion formula module plan B.

[0038] S3: Process small batches according to formula module plan B, evaluate the quality difference between the cured tobacco and formula module plan B, and adjust relevant parameters until the quality of the cured tobacco is the same as that of formula module plan B.

[0039] S4: Perform leaf re-drying processing according to the adjusted parameter settings in formula module plan B.

[0040] Specifically, during module design, based on the formula ratio plan A designed by the module designers, and combining the moisture content α, stem content μ, and sand content β of each grade of raw tobacco leaves involved in the module plan, and the measured moisture content γ of each grade of tobacco leaves, the moisture content is uniformly converted into standard moisture, and the stem content and sand content are converted. Then, the formula ratio is recalculated to form the converted formula module plan B. Small-batch processing is carried out according to formula module plan B. Process control: The leaf-laying platform should strictly follow formula module plan B. When switching between blending cabinets, ensure that the tobacco leaves in each cabinet are a complete formula. Processes involving temperature and humidity changes, such as the first and second moistening, air separation, and re-drying processes, should establish stable parameters after the flow rate stabilizes. Evaluate the quality difference between the cured tobacco leaves and formula module plan B, adjust relevant parameters until the quality difference between the cured tobacco leaves and formula module plan B is reached, and record the relevant parameters. Then, re-drying processing is carried out according to the adjusted parameter settings of formula module plan B. This method, through scientific data analysis and meticulous process control, aims to improve the sensory quality of finished cigarette sheets and ensure their high consistency with the modular formula design. By applying this technology, a high-quality supply of raw materials can be guaranteed, effectively solving the problems existing in the sensory quality and conformity of re-dried cigarette sheets to the modular formula design, and providing a solid guarantee for the stable formulation of cigarette products.

[0041] The method also includes: calculating the maximum scale of the module based on the proportion of the formula sheet and the actual weight of the raw materials, using the "weakest link" effect, or applying the remaining tobacco leaves to other modules according to their quality and compatibility based on the scale required by the product positioning module.

[0042] Furthermore, the conversion of formula ratio plan A into formula module plan B includes:

[0043] According to the formula: = Calculate the weight N of a single grade corresponding to formula module plan B, where M is the weight of a single grade involved in formula ratio plan A.

[0044] The method also includes: designing a pre-planned tobacco leaf treatment, first brushing the front and back of the single-grade mixed sample according to the formula module ratio 5-8 times to remove tobacco dust, then shredding the sample, and placing the sample in a constant temperature and humidity environment for more than 48 hours, with a temperature of 22±2℃ and a humidity of 65±5%.

[0045] In practical applications, when dealing with proportions, it is necessary to consider the actual situation of the finished tobacco leaves after threshing and re-drying. The content of tobacco stems and dust in the leaves is low and can be ignored. Therefore, the proportion of the actual net weight of the tobacco leaves should be the standard. The proportions involved should be the weighted average of multiple sets of data. The larger the amount of original data, the more accurate the reflection of reality.

[0046] Furthermore, the step of performing leaf re-drying processing according to the adjusted parameter settings in formula module plan B includes:

[0047] The blending and leaf spreading table is strictly operated in accordance with the formula module plan B. When switching between blending cabinets, it is ensured that the tobacco leaves in each cabinet are complete formulas. The process processing parameters are controlled with the corresponding values ​​of the small batch processing records in formula module plan B as the center value. The moisture content of the tobacco leaves is controlled to ±0.5 percentage points of the center value, and the temperature is controlled to ±3℃ of the center value.

[0048] The method also includes: taking samples of the finished tobacco leaves after re-drying every 2 hours, comparing the sensory quality of the finished tobacco leaves with the conformity of the module formula design, and promptly identifying the cause when there are differences in quality, and making targeted adjustments.

[0049] Furthermore, the adjustment of relevant parameters includes:

[0050] The parameters are initially set based on the physical properties of the raw materials, including shear force, tensile strength, hygroscopicity, and thickness.

[0051] The temperature and humidity settings are based on the degree of influence of temperature and humidity on the sensory quality of tobacco raw materials.

[0052] Furthermore, the adjustment of the relevant parameters also includes:

[0053] After the first rinsing, the material temperature is 53±3℃ and the material moisture content is 16.2±0.5%. After the second rinsing, the material temperature is 56±3℃ and the material moisture content is 16.7±0.5%. The temperature of the highest drying zone of the re-drying equipment is 69±3℃.

[0054] The method also includes: continuously improving the information on the physical properties of single-grade raw materials and the impact of temperature and humidity on sensory quality by year and production location, and building the relationship with processing parameters to form a database to provide a basis for setting subsequent processing parameters.

[0055] The method also includes: designing a pre-planned tobacco sampling module, sampling raw tobacco samples or selected samples by grade, and combining samples with the actual situation of tobacco quality inspection.

[0056] In practical applications, raw tobacco samples or post-selection samples should be sampled by grade, and the samples taken from each grade should be representative. Raw tobacco samples should be prepared in accordance with the actual situation of tobacco leaf quality inspection, and the mixed weight ratio of the prepared samples should be consistent with the quality inspection situation; post-selection samples should be prepared in accordance with the actual situation of leaf selection sampling inspection, and the mixed weight ratio of the prepared samples should be consistent with the leaf selection sampling inspection situation.

[0057] In one embodiment, the tobacco flakes from a certain region are grade C3F and B2F, with weights of 21,000 dan and 6,000 dan respectively. Depending on the annual quality situation, mixing may be considered.

[0058] This module focuses on raw tobacco blending and does not involve leaf selection. The weighted stem content (μ) of raw grade tobacco leaves is calculated. C3F =24.62%, μ B2F =27.45%, weighted moisture content of tobacco leaves α C3F =14.11%, α B2F =13.55% and tobacco-weighted sandy soil ratio β C3F =0.17%, β B2F =0.08%.

[0059] Samples were prepared based on actual tobacco leaf quality inspection conditions, and the mixed-grade weight ratio of the prepared samples was consistent with the quality inspection results. The tobacco shreds were then processed and subjected to a constant temperature and humidity environment of 22±2℃ and 65±5% for 48 hours. The moisture content (γ) of the tobacco shreds was measured. C3F =13.52%, γ B2F =12.76% Based on sensory quality, the assembled modules are shown in Table 1:

[0060]

[0061] Based on the formula ratio plan A, convert it into formula module plan B:

[0062] The weight of C3F calculated according to formula ① is 28097.98 dan.

[0063] The weight of B2F is calculated according to formula ①: 5846.69 dan;

[0064] Conversion formula ratio: C3F ratio 82.78%, B2F ratio 17.22%.

[0065] Based on the actual situation of the raw materials, the actual raw material ratio is calculated to be C3F 77.78% and B2F 22.22%.

[0066] The product positioning should aim to make this module as large as possible.

[0067] Based on the barrel effect and the principle that the lower limit determines the weakest link, by comparing the actual proportion of raw materials with the proportion in the formula, the amount of C3F determines the upper limit of the scale.

[0068] Based on the proportions in the recipe sheet and the weight of C3F in the recipe sheet, calculate the required weight of B2F to form recipe sheet B, as shown in Table 2:

[0069]

[0070] Small-batch processing is carried out according to Formula Module Plan B. Process control: The leaf spreading table should be strictly operated according to Formula Module Plan B. When switching between blending cabinets, ensure that the tobacco leaves in each cabinet are of complete formula. Processes involving temperature and humidity changes, such as the first and second moistening, air separation, and re-drying processes, should establish stable parameters after the flow rate stabilizes. Evaluate the quality difference between the cured tobacco and Formula Module Plan B, adjust relevant parameters until the quality difference between the cured tobacco and Formula Module Plan B is found, and record the relevant parameters as follows: material temperature after the first moistening is 53℃, material moisture content is 16.2%; material temperature after the second moistening is 56℃, material moisture content is 16.7%; leaf stem separation process: first pass with diamond-shaped frames, frame size 3.5 inches, roller speed 560 r / min; second pass with frame size 3.0 inches, speed 620 r / min; third pass with frame size 2.5 inches, speed 850 r / min; the highest drying temperature zone of the re-drying equipment is 69℃. Based on the above-mentioned improved formula module contingency plan B small batch processing, the formula sheet will be further improved.

[0071] Process parameter control: The leaf spreading table should be strictly operated according to the formula module plan B. When switching between blending cabinets, ensure that the tobacco leaves in each cabinet are complete formulas. For processes involving temperature and humidity changes, the material temperature after the first rinsing is 53±3℃ and the material moisture content is 16.2±0.5%. After the second rinsing, the material temperature is 56±3℃ and the material moisture content is 16.7±0.5%. In the leaf and stem separation process, the first pass uses diamond-shaped frames with a frame size of 3.5 inches and a roller speed of 560±10 r / min. The second pass uses frames with a frame size of 3.0 inches and a speed of 620±10 r / min. The third pass uses frames with a frame size of 2.5 inches and a speed of 850±10 r / min. The highest drying temperature zone of the re-drying equipment is 69±3℃.

[0072] Processing quality compliance monitoring: Take samples of the finished tobacco leaves after re-drying every 2 hours to compare the sensory quality of the finished tobacco leaves with the module formula design. If there are differences in quality, find out the cause in time and make targeted adjustments.

[0073] As can be seen, this invention provides a modular design method for sliced ​​tobacco products using a leaf-pounding and re-drying process. It involves converting a pre-planned formula ratio into a pre-planned formula module, processing in small batches according to the module plan, adjusting relevant parameters based on quality differences, and then performing leaf-pounding and re-drying processing according to the adjusted parameters set in the pre-planned formula module. This solves the problem of low conformity between the sensory quality of existing leaf-pounding and re-drying finished tobacco products and the modular formula design, improving the sensory quality of the finished tobacco products, ensuring a high degree of consistency with the modular formula design, and providing a solid guarantee for the stable formulation of cigarette products.
