Description

Technical Field

[0001] The present invention relates to the technical field of reconstituted tobacco, and in particular to a method, device, equipment and storage medium for regulating and controlling the balance of reconstituted tobacco slurry. Background Art

[0002] Reconstituted tobacco has been widely used in the tobacco industry due to its good processing resistance, significant tar reduction effect and strong product quality plasticity. The production process of reconstituted tobacco leaves first extracts the tobacco raw materials, obtains solid residues and extracts containing tobacco components after solid-liquid separation, concentrates and blends the extracts to form coating liquids, fills the solid residues to obtain slurry, and then manufactures the slurry into a substrate, applies the coating liquid on the substrate, and obtains reconstituted tobacco leaves after drying, cutting and finished product processing. In the actual production process, due to fluctuations in the quality of tobacco raw materials and process conditions, it is difficult to accurately match the amount of slurry and the amount of coating liquid, and there will be excess slurry or excess coating liquid, that is, there is a slurry imbalance. Slurry imbalance has a great impact on the product yield of reconstituted tobacco leaves and the utilization rate of tobacco raw materials.

[0003] At present, the slurry balance in the production process of reconstituted tobacco is regulated by adjusting the amount of filler auxiliary materials in the slurry and the amount of slurry of reconstituted tobacco.

[0004] However, adjusting the amount of filler auxiliary materials in the slurry to regulate the slurry balance during the production process of reconstituted tobacco will affect the component parameters of the reconstituted tobacco, and the quality of the finished reconstituted tobacco is difficult to guarantee. Summary of the invention

[0005] The present invention provides a method, device, equipment and storage medium for regulating the balance of slurry in reconstituted tobacco leaves, which realizes the regulation of slurry balance in the production process of reconstituted tobacco leaves without affecting the component parameters of the reconstituted tobacco leaves, thereby ensuring the quality of the finished product of the reconstituted tobacco leaves.

[0006] According to one aspect of the present invention, a method for regulating and controlling the balance of reconstituted tobacco slurry is provided, comprising:

[0007] In the process of generating reconstituted tobacco leaves, obtaining the current tobacco raw material extraction rate corresponding to the extract obtained in the process of solid-liquid separation of tobacco raw materials;

[0008] According to the difference between the ideal tobacco raw material extraction rate and the current tobacco raw material extraction rate, the extraction parameters of the extraction equipment are adjusted; the ideal tobacco raw material extraction rate is the tobacco raw material extraction rate when the amount of slurry of the reconstituted tobacco leaves generated by the tobacco raw material and the amount of the coating liquid are balanced;

[0009] The new tobacco raw material is extracted according to the adjusted extraction parameters, so that the current tobacco raw material extraction rate corresponding to the extract obtained by solid-liquid separation of the new tobacco is consistent with the ideal tobacco raw material extraction rate.

[0010] According to another aspect of the present invention, a reconstituted tobacco slurry balance control device is provided, comprising:

[0011] The current tobacco raw material extraction rate acquisition module is used to obtain the current tobacco raw material extraction rate corresponding to the extract obtained in the tobacco raw material solid-liquid separation process during the reconstituted tobacco leaf generation process;

[0012] An extraction parameter adjustment module, used for adjusting the extraction parameters of the extraction device according to the difference between the ideal tobacco raw material extraction rate and the current tobacco raw material extraction rate; the ideal tobacco raw material extraction rate is the tobacco raw material extraction rate when the amount of slurry and the amount of coating liquid of the reconstituted tobacco leaves generated by the tobacco raw material are balanced;

[0013] The new tobacco raw material extraction module is used to extract the new tobacco raw material according to the adjusted extraction parameters, so that the current tobacco raw material extraction rate corresponding to the extract obtained by solid-liquid separation of the new tobacco is consistent with the ideal tobacco raw material extraction rate.

[0014] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0019] The technical solution of the embodiment of the present invention is to obtain the current tobacco raw material extraction rate corresponding to the extract obtained in the solid-liquid separation process of the tobacco raw material during the reconstituted tobacco leaf generation process, and adjust the extraction parameters of the extraction equipment according to the difference between the ideal tobacco raw material extraction rate and the current tobacco raw material extraction rate. The ideal tobacco raw material extraction rate is the tobacco raw material extraction rate when the slurry amount and the coating liquid amount of the reconstituted tobacco leaves generated from the tobacco raw material are balanced. According to the adjusted extraction parameters, new tobacco raw materials are extracted so that the tobacco raw material extraction rate corresponding to the extract obtained in the solid-liquid separation process of the new tobacco raw material is consistent with the ideal tobacco raw material extraction rate. This solves the problem that the existing technology adjusts the amount of filler auxiliary materials in the slurry to regulate the slurry balance in the reconstituted tobacco leaf generation process, which will affect the component parameters of the reconstituted tobacco leaves and make it difficult to ensure the quality of the finished reconstituted tobacco leaves.

[0030] Embodiment 1

[0031] Figure 1 A flowchart of a method for regulating the balance of reconstituted tobacco slurry provided in Embodiment 1 of the present invention. The embodiment of the present invention is applicable to the case of regulating the balance of reconstituted tobacco slurry, and the method can be performed by a reconstituted tobacco slurry balance regulating device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device that carries the function of regulating the balance of reconstituted tobacco slurry.

[0032] See also Figure 1 The method for regulating and controlling the balance of reconstituted tobacco slurry comprises:

[0033] S110. In the process of generating reconstituted tobacco leaves, a current tobacco raw material extraction rate corresponding to an extract obtained in a tobacco raw material solid-liquid separation process is obtained.

[0034] The specific process of reconstituted tobacco leaf production is as follows: first, extract the tobacco raw material, and obtain solid residue and extract containing tobacco components after solid-liquid separation process; then, the solid residue is filled to obtain slurry, and then the slurry is made into a substrate, and the extract is concentrated and formulated to form a coating liquid; finally, the coating liquid is applied to the substrate, and after drying, cutting and finished product processing, the reconstituted tobacco leaf is obtained. Among them, extraction is also called extraction, leaching or leaching. In the extraction process (i.e., solid-liquid separation process), the insoluble solids and solubles in the tobacco raw materials are separated according to the process requirements to obtain solid residue and extract respectively. The amount of solid residue determines the amount of slurry of the reconstituted tobacco leaf, and the amount of extract determines the amount of coating liquid of the reconstituted tobacco leaf. Therefore, controlling the current tobacco raw material extraction rate can realize the control of the reconstituted tobacco leaf production process, which is the most effective means to control the slurry balance of the reconstituted tobacco leaf without affecting the quality of the finished product of the reconstituted tobacco leaf. The current tobacco raw material extraction rate may be the ratio of the absolute dry weight of soluble matter in the extract obtained by the tobacco raw material through the solid-liquid separation process at the current moment to the absolute dry weight of the tobacco raw material.

[0035] Specifically, in the process of generating reconstituted tobacco leaves, the absolute dry weight of soluble matter in the extract obtained after the tobacco raw material undergoes a solid-liquid separation process at the current moment and the absolute dry weight of the tobacco raw material can be obtained to calculate the current tobacco raw material extraction rate.

[0036] S120. Adjusting extraction parameters of the extraction equipment according to the difference between the ideal tobacco raw material extraction rate and the current tobacco raw material extraction rate; the ideal tobacco raw material extraction rate is the tobacco raw material extraction rate when the amount of slurry and the amount of coating liquid of the reconstituted tobacco leaves generated by the tobacco raw material are balanced.

[0037] Due to the requirements of the quality of reconstituted tobacco products, in the process of reconstituted tobacco generation, a single piece of reconstituted tobacco needs to be generated according to the preset slurry amount and coating liquid amount. It can be understood that the slurry amount and coating liquid amount of a single piece of reconstituted tobacco have a certain ratio, that is, the coating rate. Therefore, in the process of generating tobacco raw materials, when the ratio between the slurry amount and the coating liquid amount of the reconstituted tobacco leaves is the same as the coating rate of a single piece of reconstituted tobacco leaves, the slurry of the tobacco raw materials is balanced. It can be understood that there will be no slurry surplus or coating liquid surplus at this time. The ideal tobacco raw material extraction rate can be the tobacco raw material extraction rate when the slurry amount and coating liquid amount of the reconstituted tobacco leaves generated by the tobacco raw materials are balanced. The ideal tobacco raw material extraction rate can be the empirical value of the tobacco raw material extraction rate preset by the technician. The ideal tobacco raw material extraction rate can be preset and adjusted according to the experience of the technician. The current tobacco raw material extraction rate is mainly affected by factors such as tobacco raw material quality, extraction temperature, extraction time, extraction equipment liquid level, agitator speed, and solid residue squeeze degree after extraction. Due to the volatility of tobacco raw material quality, even if other process parameters remain stable, in fact tobacco raw material extraction rate is also constantly changing, therefore, for reaching the ideal tobacco raw material extraction rate, the process parameters of extraction equipment in the extraction process need to be regulated. Extraction equipment can be the equipment that tobacco raw material is extracted (or solid-liquid separation). Extraction parameters can be the process parameters of extraction equipment. Exemplary, extraction parameters can comprise extraction temperature, extraction time, extraction equipment liquid level, agitator speed and extraction back solids residue squeeze dryness and other process parameters.

[0038] Specifically, if the ideal tobacco raw material extraction rate is greater than the current tobacco raw material extraction rate, the extraction parameters of the extraction equipment can be adjusted according to the difference between the ideal tobacco raw material extraction rate and the current tobacco raw material extraction rate to increase the current tobacco raw material extraction rate to the ideal tobacco raw material extraction rate; if the ideal tobacco raw material extraction rate is equal to the current tobacco raw material extraction rate, the extraction parameters of the extraction equipment will not be adjusted; if the ideal tobacco raw material extraction rate is less than the current tobacco raw material extraction rate, the extraction parameters of the extraction equipment can be adjusted according to the difference between the ideal tobacco raw material extraction rate and the current tobacco raw material extraction rate to reduce the current tobacco raw material extraction rate to the ideal tobacco raw material extraction rate.

[0039] S130. Extracting the new tobacco raw material according to the adjusted extraction parameters so that the current tobacco raw material extraction rate corresponding to the extract obtained in the solid-liquid separation process of the new tobacco raw material is consistent with the ideal tobacco raw material extraction rate.

[0040] So that the current tobacco raw material extraction rate corresponding to the extract obtained in the new tobacco raw material solid-liquid separation process is consistent with the ideal tobacco raw material extraction rate. It can be understood that the ideal tobacco raw material extraction rate is the target value for adjusting the current tobacco raw material extraction rate.

[0041] Specifically, the extraction equipment can be updated to the adjusted extraction parameters to extract new tobacco raw materials, so that the current tobacco raw material extraction rate corresponding to the extract obtained in the solid-liquid separation process of the new tobacco raw materials is consistent with the ideal tobacco raw material extraction rate.

[0042] The existing technology adjusts the amount of filler auxiliary materials in the slurry, for example, adjusting the amount of CaCO in the slurry. 3 The addition ratio of the fiber material in the slurry is adjusted, and while adjusting the amount of slurry, the composition parameters of each component in the slurry are also adjusted, which reduces the quality stability of the base sheet generated by the slurry and makes it difficult to ensure the quality of the finished product of the reconstituted tobacco.

[0043] The technical solution of the embodiment of the present invention is to obtain the current tobacco raw material extraction rate corresponding to the extract obtained in the solid-liquid separation process of the tobacco raw material during the reconstituted tobacco leaf generation process, and adjust the extraction parameters of the extraction equipment according to the difference between the ideal tobacco raw material extraction rate and the current tobacco raw material extraction rate. The ideal tobacco raw material extraction rate is the tobacco raw material extraction rate when the slurry amount and the coating liquid amount of the reconstituted tobacco leaf generated from the tobacco raw material are balanced. According to the adjusted extraction parameters, new tobacco raw material is extracted so that the current tobacco raw material extraction rate corresponding to the extract obtained in the solid-liquid separation process of the new tobacco raw material is consistent with the ideal tobacco raw material extraction rate. The current tobacco raw material extraction rate is adjusted only by adjusting the extraction parameters of the extraction equipment, so that the amount of solid residue and the amount of extract obtained in the solid-liquid separation process of the tobacco raw material are adjusted, and then the amount of slurry and the amount of coating liquid of the reconstituted tobacco leaf generated from the tobacco raw material are adjusted. At the same time, the change of each component parameter of the slurry and the coating liquid for generating the reconstituted tobacco leaf is avoided. Under the premise of not affecting the component parameters of the reconstituted tobacco leaf, the slurry balance in the reconstituted tobacco leaf generation process is adjusted, and the quality of the reconstituted tobacco leaf is guaranteed.

[0044] In an optional embodiment of the present invention, obtaining the current tobacco raw material extraction rate corresponding to the extract obtained in the tobacco raw material solid-liquid separation process includes: obtaining the solid content of the current solid residue obtained in the tobacco raw material solid-liquid separation process, the solid content of the current extract, and the current liquid-solid ratio; based on the following current extraction rate calculation formula, the solid content of the current solid residue, the solid content of the current extract, and the current liquid-solid ratio are calculated to obtain the current tobacco raw material extraction rate:

[0045]

[0046] Among them, E is the current tobacco raw material extraction rate; N is the current liquid-solid ratio; D is the solid content of the current solid residue; C is the solid content of the current extract.

[0047] The solid content of the current solid residue can be the ratio between the absolute dry weight of the solid residue obtained by the tobacco raw material after the solid-liquid separation process at the current moment and the weight of the undried solid residue. It can be understood that the solid content of the current solid residue is used to characterize the specific gravity after the current solid residue removes the water content. The solid content of the current extract can be the ratio between the absolute dry weight of the soluble matter in the extract obtained by the tobacco raw material after the solid-liquid separation process at the current moment and the weight of the extract. The current liquid-solid ratio can be the ratio between the absolute dry weight of the solvent of the extraction equipment at the current moment and the tobacco raw material. Exemplary, the solvent of the extraction equipment at the current moment can be clear water.

[0048] Specifically, the solid content of the current solid residue, the solid content of the current extract and the current liquid-solid ratio measured by the oven method can be obtained. The solid content of the current solid residue, the solid content of the current extract and the current liquid-solid ratio are input into the current extraction rate formula to obtain the current extraction rate of the tobacco raw material.

[0049] Optionally, the calculation formula for the absolute dry weight of the tobacco raw material, the calculation formula for the solvent weight of the extraction equipment and the calculation formula for the original extraction rate may be integrated to obtain the calculation formula for the current extraction rate.

[0050] Among them, the calculation formula of the absolute dry weight of tobacco raw materials is as follows:

[0051] M = M' × D + L × (1-R) ​​× C;

[0052] Wherein, M is the absolute dry weight of tobacco raw material; M' is the weight of undried solid residue; D is the solid content of the current solid residue; L is the weight of the extract; R is the current reflux ratio; C is the solid content of the current extract.

[0053] The solvent weight of the extraction equipment is calculated as follows:

[0054] N×M=M'×(1-D)+L×(1-R)×(1-C);

[0055] Wherein, N is the current liquid-solid ratio; M is the absolute dry weight of the tobacco raw material; M' is the weight of the undried solid residue; D is the solid content of the current solid residue; L is the weight of the extract; R is the current reflux ratio; and C is the solid content of the current extract.

[0056] The calculation formula for the absolute dry weight of tobacco raw materials and the calculation formula for the solvent weight of the extraction equipment are combined to obtain the following calculation formula for the weight of the extract:

[0057]

[0058] Wherein, L is the weight of the extract; N is the current liquid-to-solid ratio; D is the solid content of the current solid residue; R is the current reflux ratio; C is the solid content of the current extract; and M is the absolute dry weight of the tobacco raw material.

[0059] The original extraction rate is calculated as follows:

[0060]

[0061] Wherein, E is the current extraction rate of tobacco raw material; L is the weight of the extract; R is the current reflux ratio; C is the solid content of the current extract; M is the absolute dry weight of the tobacco raw material.

[0062] The calculation formula for the weight of the extract and the original extraction rate calculation formula are combined to obtain the following current extraction rate calculation formula:

[0063]

[0064] Wherein, E is the current tobacco raw material extraction rate; N is the current liquid-solid ratio; D is the solid content of the current solid residue; and C is the solid content of the current extract.

[0065] This scheme obtains the solid content of the current solid residue, the solid content of the current extract and the current liquid-solid ratio obtained in the solid-liquid separation process of the tobacco raw material, and calculates the solid content of the current solid residue, the solid content of the current extract and the current liquid-solid ratio based on the current extraction rate calculation formula to obtain the current tobacco raw material extraction rate. Through the current extraction rate calculation formula, the efficiency and accuracy of the current tobacco raw material extraction rate calculation are improved.

[0066] In an optional embodiment of the present invention, after extracting new tobacco raw material according to the adjusted extraction parameters, it also includes: correcting the ideal tobacco raw material extraction rate according to the amount of slurry and / or coating liquid of reconstituted tobacco leaves generated from the new tobacco raw material.

[0067] The ideal tobacco raw material extraction rate is an empirical value of the tobacco raw material extraction rate set in advance by technicians. In the actual production process of reconstituted tobacco leaves, due to the volatility of the production process, for example, the extraction equipment fails and stops, resulting in unexpected losses of slurry or coating liquid, the ideal tobacco raw material extraction rate may have a certain deviation. Therefore, the ideal tobacco raw material extraction rate can be corrected according to the amount of slurry and / or coating liquid of the reconstituted tobacco leaves generated by the new tobacco raw materials.

[0068] Optionally, if after multiple consecutive adjustment batches, there is still a surplus of slurry of reconstituted tobacco leaves generated from new tobacco raw materials, the ideal tobacco raw material extraction rate can be increased.

[0069] Optionally, if after multiple consecutive adjustment batches, there is still a surplus of coating liquid for reconstituted tobacco leaves generated from new tobacco raw materials, the ideal tobacco raw material extraction rate can be reduced.

[0070] Optionally, if after multiple consecutive adjustment batches, there is still a surplus of slurry of reconstituted tobacco leaves generated from new tobacco raw materials and the amount of coating liquid is insufficient, the ideal tobacco raw material extraction rate can be increased.

[0071] Optionally, if after multiple consecutive adjustment batches, the amount of slurry of reconstituted tobacco leaves generated from new tobacco raw materials is insufficient and there is still a surplus of coating liquid, the ideal tobacco raw material extraction rate can be reduced.

[0072] This solution corrects the ideal tobacco raw material extraction rate according to the amount of slurry and / or coating liquid of reconstituted tobacco leaves generated from the new tobacco raw materials after extracting the new tobacco raw materials according to the adjusted extraction parameters, taking into account the volatility of the actual production process of reconstituted tobacco leaves, and further improving the accuracy of regulating the slurry balance in the reconstituted tobacco leaf generation process.

[0073] Optionally, during the reconstituted tobacco leaf production process, the solid content of the current solid residue, the solid content of the current extract, the current reflux ratio, the current liquid-solid ratio and the current tobacco raw material extraction rate can be detected at a certain frequency to achieve real-time monitoring of various data in the reconstituted tobacco leaf production process.

[0074] In an optional embodiment of the present invention, the tobacco raw material includes at least one of tobacco shreds, tobacco dust, tobacco stems, waste shredded tobacco and tobacco dust rods.

[0075] Tobacco leaf scraps, tobacco dust, tobacco stems, discarded shredded tobacco and tobacco dust sticks are all wastes in the actual tobacco production process. Among them, tobacco leaf scraps can be the shredded tobacco produced in the process of grading and packaging. Tobacco dust can be the fine dust produced in the process of burning cigarettes. Tobacco stems can be the coarse and hard veins in tobacco leaves. Discarded shredded tobacco can be the shredded tobacco that is not of quality problem but is produced as defective due to factors such as raw materials, equipment and operation in the tobacco production process. Tobacco dust sticks can be produced by pressing tobacco dust.

[0076] This solution concretizes the tobacco raw materials into at least one of tobacco leaves, tobacco dust, tobacco stems, discarded shredded tobacco and tobacco dust sticks, realizes the recycling of waste materials in the tobacco production process, and improves the utilization rate of tobacco raw materials.

Based on the above embodiments, the embodiment of the present invention concretizes the "extraction parameter" as the "current reflux ratio", and concretizes "adjusting the extraction parameters of the extraction equipment according to the difference between the ideal tobacco raw material extraction rate and the current tobacco raw material extraction rate" as "obtaining the solid content of the current solid residue of the tobacco raw material, the solid content of the current extract, the current reflux ratio and the current liquid-solid ratio, calculating the ideal liquid-solid ratio according to the ideal tobacco raw material extraction rate, the current solid content of the solid residue and the solid content of the current extract, calculating the reflux ratio adjustment ratio according to the solid content of the current solid residue, the solid content of the current extract, the current reflux ratio and the difference between the ideal liquid-solid ratio and the current liquid-solid ratio, and adjusting the extraction parameters according to the reflux ratio adjustment ratio", thereby improving the convenience of adjusting the current tobacco raw material extraction rate, improving the immediacy of the feedback of the adjustment result of the current tobacco raw material extraction rate, reducing the impact on the process of reconstituted tobacco production, and improving the stability of the quality of the finished product of reconstituted tobacco. It should be noted that for the parts not described in detail in the embodiments of the present invention, reference may be made to the descriptions of other embodiments.

[0079] See also Figure 2 The method for regulating and controlling the balance of reconstituted tobacco slurry comprises:

[0080] S210. In the process of generating reconstituted tobacco leaves, a current tobacco raw material extraction rate corresponding to the extract obtained in the process of solid-liquid separation of the tobacco raw material is obtained.

[0081] S220, obtaining the current solid content of the solid residue of the tobacco raw material, the current solid content of the extract, the current reflux ratio and the current liquid-solid ratio; the current liquid-solid ratio is the ratio of the solvent weight of the extraction equipment at the current moment to the absolute dry weight of the tobacco raw material.

[0082] The current reflux ratio can be the ratio between the weight of the extracting liquid that refluxes into the extraction device at the current moment and the weight of the extracting liquid that the extraction device outputs at the current moment. The current liquid-solid ratio can be the ratio between the solvent weight of the extraction device at the current moment and the absolute dry weight of the tobacco raw material. The solvent weight of the extraction device at the current moment can be the solvent weight input to the extraction device at the current moment. Exemplarily, the solvent of the extraction device can be clear water. The absolute dry weight of the tobacco raw material can be the absolute dry weight of the tobacco raw material input to the extraction device at the current moment. The input of the extraction device at the current moment is solvent and tobacco raw material, and the output is solid residue and extracting liquid.

[0083] Specifically, the solid content of the current solid residue measured by the oven method, the solid content of the current extract, and the current liquid-solid ratio can be obtained. The weight of the extract refluxed into the extraction device at the current moment and the weight of the extract output by the extraction device at the current moment can be obtained to obtain the current reflux ratio corresponding to the extraction parameters.

[0084] S230, calculating an ideal liquid-to-solid ratio according to an ideal tobacco raw material extraction rate, a current solid content of the solid residue, and a current solid content of the extract.

[0085] Specifically, the current extraction rate calculation formula can be transformed to obtain the current liquid-solid ratio calculation formula:

[0086]

[0087] Wherein, N is the current liquid-solid ratio; E is the current tobacco raw material extraction rate; C is the solid content of the current extract; and D is the solid content of the current solid residue.

[0088] The ideal liquid-solid ratio calculation formula can be deduced based on the ideal tobacco raw material extraction rate:

[0089]

[0090] Where N 0 is the ideal liquid-to-solid ratio; E 0 is the ideal tobacco raw material extraction rate; C is the solid content of the current extract; D is the solid content of the current solid residue.

[0091] The ideal tobacco raw material extraction rate, the solid content of the current solid residue and the solid content of the current extract are input into the ideal liquid-solid ratio calculation formula to obtain the ideal liquid-solid ratio.

[0092] S240, calculating the reflux ratio adjustment ratio according to the current solid content of the solid residue, the current solid content of the extract, the current reflux ratio, and the difference between the ideal liquid-solid ratio and the current liquid-solid ratio.

[0093] The reflux ratio adjustment ratio can be the adjustment ratio of the current reflux ratio. Optionally, the reflux ratio adjustment ratio can be the multiple product ratio of the current reflux ratio or the increase ratio of the current reflux ratio. On the one hand, in the process of reconstituted tobacco leaf generation, the extraction process parameters such as extraction temperature, extraction time and extraction equipment liquid level are all certain. If the extraction process parameters such as extraction temperature, extraction time and extraction equipment liquid level are adjusted on site, it will inevitably cause large fluctuations in the production link. For example, if the extraction time is adjusted, the extraction process will be shortened or extended, which will affect the connection of subsequent processes and the coordinated control of the entire production link. If the extraction temperature is changed, the quality of the extract will be affected. On the other hand, by adjusting the extraction process parameters such as extraction temperature, extraction time and extraction equipment liquid level to adjust the current tobacco raw material extraction rate, the adjustment effect of the current tobacco raw material extraction rate is slow to feedback. In the process of extracting tobacco raw materials, part of the extract is usually refluxed to achieve the purpose of increasing the concentration of the extract and reducing the pressure of the equipment in the concentration section. In the extraction process (i.e., solid-liquid separation process), under the premise of ensuring the stability of the extraction equipment liquid level, the weight of the solvent added per unit time is actually affected by the current reflux ratio. It can be understood that by increasing the current reflux ratio, the weight of solvent input to the extraction device per unit time decreases, and the current liquid-solid ratio of the extraction process decreases; by reducing the current reflux ratio, the weight of solvent input to the extraction device per unit time increases, and the current liquid-solid ratio of the extraction process increases. Laboratory research results show that the current liquid-solid ratio has a greater impact on the current extraction rate. Therefore, without changing the basic extraction process parameters, the current liquid-solid ratio can be adjusted by adjusting the current reflux ratio, thereby achieving online control of the current tobacco raw material extraction rate and achieving the purpose of controlling the slurry balance during the generation of reconstituted tobacco leaves.

[0094] Specifically, the reflux ratio adjustment ratio can be calculated according to the difference between the ideal liquid-solid ratio and the current liquid-solid ratio, the solid content of the current solid residue, the solid content of the current extract, and the current reflux ratio.

[0095] S250, adjusting the extraction parameters according to the reflux ratio.

[0096] Optionally, the current reflux ratio may be adjusted according to the reflux ratio adjustment ratio.

[0097] Exemplarily, if the reflux ratio adjustment ratio is a multiple product ratio of the current reflux ratio, the product between the current reflux ratio and the reflux ratio adjustment ratio may be calculated to update the current reflux ratio.

[0098] S260, extracting the new tobacco raw material according to the adjusted extraction parameters, so that the current tobacco raw material extraction rate corresponding to the extract obtained in the solid-liquid separation process of the new tobacco raw material is consistent with the ideal tobacco raw material extraction rate.

[0099] The technical solution of the embodiment of the present invention is to obtain the current tobacco raw material extraction rate corresponding to the extract obtained in the solid-liquid separation process of the tobacco raw material during the generation process of reconstituted tobacco leaves, obtain the solid content of the current solid residue of the tobacco raw material, the solid content of the current extract, the current reflux ratio and the current liquid-solid ratio, calculate the ideal liquid-solid ratio according to the ideal tobacco raw material extraction rate, the current solid content of the solid residue and the solid content of the current extract, calculate the reflux ratio adjustment ratio according to the current solid content of the solid residue, the current solid content of the extract, the current reflux ratio and the difference between the ideal liquid-solid ratio and the current liquid-solid ratio, adjust the extraction parameters according to the reflux ratio adjustment ratio, and extract new tobacco raw material according to the adjusted extraction parameters so that the current tobacco raw material extraction rate corresponding to the extract obtained in the solid-liquid separation process of the new tobacco raw material is consistent with the ideal tobacco raw material extraction rate. First of all, the adjustment method is simple, and only conventional detection data (i.e., the solid content of the current solid residue, the solid content of the current extract, the current reflux ratio, and the difference between the ideal liquid-solid ratio and the current liquid-solid ratio) need to be adjusted. The present reflux ratio is simply analyzed based on the previous reflux ratio and the current liquid-solid ratio, and the current reflux ratio is adjusted to realize the control of the current tobacco raw material extraction rate, thereby improving the convenience of adjusting the current tobacco raw material extraction rate; secondly, the adjustment result of the current tobacco raw material extraction rate is fed back in time, thereby improving the immediacy of the adjustment result feedback of the current tobacco raw material extraction rate; and the current reflux ratio is adjusted by adjusting the reflux ratio, without changing the key process parameters such as the extraction temperature, extraction time, extraction equipment liquid level, agitator speed and the degree of squeeze-dryness of the solid residue after extraction in the extraction section (i.e., the extraction process), thereby realizing the adjustment of the current tobacco raw material extraction rate, thereby reducing the impact on the reconstituted tobacco production process; finally, in the process of adjusting the current reflux ratio, the key process parameters such as the extraction temperature and extraction time that may affect the quality of the extract are not changed, and the key component parameters such as the addition ratio and coating rate of the filler auxiliary materials that affect the content of the main components in the finished product are not changed, thereby improving the stability of the finished product quality of the reconstituted tobacco.

[0100] In an optional embodiment of the present invention, the reflux ratio adjustment ratio is calculated according to the solid content of the current solid residue, the solid content of the current extract, the current reflux ratio corresponding to the extraction parameters, and the difference between the ideal liquid-solid ratio and the current liquid-solid ratio, including: based on the following reflux ratio adjustment ratio calculation formula, according to the current solid content of the solid residue, the solid content of the current extract, the current reflux ratio corresponding to the extraction parameters, and the difference between the ideal liquid-solid ratio and the current liquid-solid ratio, the reflux ratio adjustment ratio is calculated:

[0101]

[0102] Among them, R' is the reflux ratio adjustment ratio; N is the current liquid-to-solid ratio; N 0 is the ideal liquid-to-solid ratio; R is the current reflux ratio corresponding to the extraction parameters; D is the solid content of the current solid residue; C is the solid content of the current extract.

[0103] Optionally, the calculation formula for the weight of the extract and the original formula for adjusting the reflux ratio may be combined to obtain a calculation formula for the reflux ratio adjustment ratio.

[0104] The weight of the extract is calculated as follows:

[0105]

[0106] Wherein, L is the weight of the extract; N is the current liquid-to-solid ratio; D is the solid content of the current solid residue; R is the current reflux ratio; C is the solid content of the current extract; and M is the absolute dry weight of the tobacco raw material.

[0107] The original formula for adjusting the reflux ratio is as follows:

[0108]

[0109] Where, R' is the reflux ratio adjustment ratio; M is the absolute dry weight of tobacco raw materials; N is the current liquid-to-solid ratio; N 0 is the ideal liquid-to-solid ratio; C is the solid content of the current extract; L is the weight of the extract.

[0110] It can be understood that the reflux ratio adjustment ratio can be the ratio between the weight of the extract that needs to be adjusted back to the extraction device and the weight of the extract (i.e., the total weight of the extract). Further, the weight of the extract that needs to be adjusted back to the extraction device can be the ratio between the weight of the solvent that needs to be adjusted back to the extraction device and the solvent concentration of the extract. Therefore, the above original formula for the reflux ratio adjustment ratio can be obtained.

[0111] This solution calculates the reflux ratio adjustment ratio based on the reflux ratio adjustment ratio calculation formula according to the solid content of the current solid residue, the solid content of the current extract, the current reflux ratio corresponding to the extraction parameters, and the difference between the ideal liquid-solid ratio and the current liquid-solid ratio, thereby avoiding the problem of low adjustment accuracy caused by relying on experience to adjust the extraction parameters. The reflux ratio adjustment ratio is calculated through the scientific and precise mathematical correspondence between the parameters, thereby further improving the accuracy of the extraction parameter adjustment, thereby improving the accuracy of the current tobacco raw material extraction rate adjustment and the accuracy of the slurry balance control of the reconstituted tobacco leaves.

[0112] In an optional embodiment of the present invention, the extraction parameters are adjusted according to the reflux ratio adjustment ratio, including: summing the reflux ratio adjustment ratio and the current reflux ratio to update the extraction parameters.

[0113] Specifically, the current reflux ratio and the reflux ratio adjustment ratio may be summed to update the current reflux ratio. For example, if the reflux ratio adjustment ratio is positive, the current reflux ratio is increased according to the reflux ratio adjustment ratio; if the reflux ratio adjustment ratio is negative, the current reflux ratio is decreased according to the reflux ratio adjustment ratio.

[0114] This solution updates the extraction parameters by summing the reflux ratio adjustment ratio and the current reflux ratio, and uses a simpler calculation method to update the extraction parameters, thereby improving the adjustment efficiency of the extraction parameters.

[0115] Exemplarily, Table 1 is a data record table of the tobacco raw material extraction process in each adjustment batch. Among them, in the extraction process (or solid-liquid separation process) of the tobacco raw material of the first adjustment batch, the current liquid-solid ratio N=6:1, and the current reflux ratio R=50%. In the process of extracting the tobacco raw material, the solid content D of the current solid residue after the solid-liquid separation process and the solid content C of the current extract are measured every 8 hours. According to the current extraction rate calculation formula, the current tobacco raw material extraction rate E is obtained. According to the ideal liquid-solid ratio calculation formula, the ideal tobacco raw material extraction rate E is calculated. 0 The ideal liquid-to-solid ratio N is 42% 0 . Finally, according to the reflux ratio adjustment ratio calculation formula, the reflux ratio adjustment ratio R' is calculated, and the current reflux ratio is adjusted according to the reflux ratio adjustment ratio R'. According to the adjusted current reflux ratio, the next adjusted batch of tobacco raw materials is extracted so that the current tobacco raw material extraction rate corresponding to the extract obtained by solid-liquid separation of the new tobacco raw material is consistent with the ideal tobacco raw material extraction rate.

[0118] Figure 3 It is a line chart of the current tobacco raw material extraction rate and the remaining coating liquid amount corresponding to each adjustment batch provided in the second embodiment of the present invention. Figure 3 Corresponding to Table 1. Figure 3 As shown, during the extraction process of the first adjustment batch of tobacco raw materials, the current tobacco raw material extraction rate E = 45.44%, compared with the ideal tobacco raw material extraction rate E 0=42%, the current tobacco raw material extraction rate of the first adjustment batch is high, so that the coating liquid amount is slightly surplus, for example, the remaining coating liquid amount is 80kg. After 4 rounds of adjustment, the current tobacco raw material extraction rate of each adjustment batch after the 5th adjustment batch is basically stabilized at about 42% of the ideal tobacco raw material extraction rate, that is, the difference between the current tobacco raw material extraction rate and the ideal tobacco raw material extraction rate is less than or equal to the preset tobacco extraction rate difference threshold value (for example, 5%), and the remaining coating liquid amount is also stabilized at a relatively low level, thereby achieving the control of the slurry balance of the reconstituted tobacco leaves.

[0119] Table 2 is a data record table of the tobacco raw material extraction process in each adjustment batch. Among them, in the extraction process (or solid-liquid separation process) of the tobacco raw material of the first adjustment batch, the current liquid-solid ratio N=6:1, and the current reflux ratio R=30%. In the process of extracting the tobacco raw material, the solid content D of the current solid residue and the solid content C of the current extract after the extraction and solid-liquid separation process are measured every 8 hours. According to the current extraction rate calculation formula, the current tobacco raw material extraction rate E is obtained. According to the ideal liquid-solid ratio calculation formula, the ideal tobacco raw material extraction rate E is calculated. 0 The ideal liquid-to-solid ratio N is 45% 0 . Finally, according to the reflux ratio adjustment ratio calculation formula, the reflux ratio adjustment ratio R' is calculated, and the current reflux ratio is adjusted according to the reflux ratio adjustment ratio R'. According to the adjusted current reflux ratio, the next adjusted batch of tobacco raw materials is extracted so that the current tobacco raw material extraction rate corresponding to the extract obtained by solid-liquid separation of the new tobacco raw material is consistent with the ideal tobacco raw material extraction rate.

[0121]

[0122] Figure 4 It is a line chart of the current tobacco raw material extraction rate and the remaining coating liquid amount corresponding to each adjustment batch provided in the second embodiment of the present invention. Figure 4 Corresponding to Table 2. Figure 4 As shown in FIG. 1 , during the extraction process of the first adjustment batch of tobacco raw materials, the current tobacco raw material extraction rate E = 40.36%, compared with the ideal tobacco raw material extraction rate E 0=45%, the current tobacco raw material extraction rate of the first adjustment batch is low, resulting in insufficient coating liquid, for example, the remaining coating liquid amount is -450kg. After 5-6 rounds of adjustment, the current tobacco raw material extraction rate of the 5-6 adjustment batches is basically stable at about 45% of the ideal tobacco raw material extraction rate, that is, the difference between the current tobacco raw material extraction rate and the ideal tobacco raw material extraction rate is less than or equal to the preset tobacco extraction rate difference threshold (for example, 5%), and the remaining coating liquid amount also tends to balance. However, the remaining coating liquid amount is still insufficient, so in the 7th adjustment batch, the ideal tobacco raw material extraction rate is corrected to E 0 =47%. After 5 rounds of adjustment, the current tobacco raw material extraction rate of each adjustment batch after the 12th adjustment batch is basically stabilized at about 47% of the ideal tobacco raw material extraction rate, and the remaining coating liquid amount is also stabilized at a low level, thereby achieving the control of the slurry balance of the reconstituted tobacco leaves.

[0123] It can be seen from the above examples that the current reflux ratio is adjusted by adjusting the reflux ratio, thereby realizing the adjustment of the current tobacco raw material extraction rate. The operability is strong and the application effect is good. The current tobacco raw material extraction rate can be adjusted without affecting the key component parameters and key process parameters, thereby ensuring the slurry balance in the process of reconstructed tobacco leaf production, reducing the production consumption rate of tobacco raw materials, and improving the finished product yield of reconstructed tobacco leaves. It has good economy and practicality.
