[0021] like Figure 1As shown, the production control method for drying the end and end of tobacco shreds can at least include the following steps: Step 102: Obtain historical tobacco drying data, and determine first control data from the historical tobacco drying data.

[0022] In an embodiment of the present application, the production control method for drying the dry head and tail of tobacco can be but is not limited to being applied to a control terminal, which can be connected to a tobacco drying machine (for example, a one-stage thin-plate drying machine or a two-stage thin-plate drying machine) to obtain data collected by the tobacco drying machine when drying the tobacco, and combine the historical drying data of the tobacco drying machine to accurately control the moisture content of the entire drying process of the tobacco drying machine to ensure the consistency and stability of the final tobacco product, thereby meeting the market demand for high-quality tobacco.

[0023] Here, the data collected by the tobacco drying machine when drying the tobacco may include but is not limited to the inlet moisture content of the tobacco (also understood as inlet moisture), the outlet temperature of the tobacco and the ambient humidity. Each type of data may be collected by a sensor or control device arranged at a corresponding position and fed back to the control terminal in real time; the tobacco involved in the historical drying data of the tobacco drying machine may belong to the same batch of tobacco as the tobacco currently being dried. It may include but is not limited to the historical tobacco temperature, historical outlet moisture, historical inlet moisture content (also understood as inlet moisture), historical hot air speed, historical dehumidification damper opening and historical ambient humidity at multiple historical moments. Each type of data may also be collected by a sensor or control device arranged at a corresponding position and pre-stored in the control terminal. The historical drying data may also include historical inlet tobacco flow, historical ambient temperature, historical steam pressure, historical steam mass flow in different cylinder wall structures and historical cylinder temperature, but is not limited to this.

[0024] It should be noted that when the tobacco drying machine is drying the tobacco, it can include but is not limited to the pre-production stage, material preparation stage, dry head stage, stable stage and dry tail stage. The starting status of the tobacco drying machine and the monitoring data of the electronic scale corresponding to different stages are different. That is, by querying the starting status of the tobacco drying machine and the detected electronic scale data, the stage of the tobacco drying machine when it is drying the tobacco can be determined in real time. Here, the start-up state of the tobacco drying machine in the non-production stage is not started, and the cumulative amount of the monitored electronic scale is less than 10; the start-up state of the tobacco drying machine in the preparation stage is started, and the cumulative amount of the monitored electronic scale is less than 10; the dry head stage can be understood as a stage where the front end of the tobacco is prone to premature drying, the start-up state of the tobacco drying machine in the dry head stage is started, the cumulative amount of the monitored electronic scale is less than or equal to 5000, and the moisture content of the outlet tobacco is less than or equal to 10; the stable stage can be understood as a stage where the tobacco is dried steadily, the start-up state of the tobacco drying machine in the stable stage is started, the cumulative amount of the monitored electronic scale is less than or equal to 11000, and the flow rate of the electronic scale is greater than or equal to 200; the dry tail stage can be understood as a stage where the end of the tobacco is not fully dried at the end of the drying process, the start-up state of the tobacco drying machine in the dry tail stage is started, the cumulative amount of the monitored electronic scale is greater than or equal to 11000, and the flow rate of the electronic scale is less than or equal to 200, and is not limited to this.

[0025] It can be understood that the control terminal obtains the historical drying data of the tobacco, determines the first control data from the historical drying data, and bakes the tobacco according to the first control data, so as to obtain at least two sets of tobacco monitoring data based on a preset time interval after the tobacco is in the dry head stage; then, the second control data is obtained according to all the tobacco monitoring data and the first control data, and the tobacco is dried according to the second control data, so as to achieve precise control of the tobacco dry head stage by combining historical production data with real-time monitoring information; secondly, after the tobacco is in the drying tail stage, the third control data is obtained according to the duration of the tobacco in the drying tail stage and the second control data, and the tobacco is dried according to the third control data, so as to achieve precise control of the tobacco drying tail stage by combining the duration, thereby ensuring the uniformity of moisture distribution of the tobacco and the stability of product quality in the entire drying process, meeting the market demand for high-quality tobacco, and also providing technical support for the intelligent manufacturing transformation of the tobacco industry, and promoting the digitalization and intelligent development of the production process.

[0026] Specifically, when drying tobacco, the control terminal can, but is not limited to, query the historical drying data consistent with the tobacco batch currently being dried in the historical database, and can determine the first control data for controlling the moisture content of the exported tobacco from the historical drying data. Here, the historical database may include the historical drying data corresponding to multiple tobacco batches, and the data types included in the historical drying data corresponding to each tobacco batch can refer to the above description, and the determined first control data can be multiple types of data with the strongest correlation with the moisture content of the exported tobacco, such as but not limited to the dehumidification damper opening and the hot air speed, that is, by adjusting the dehumidification damper opening and the hot air speed when the tobacco drying machine is drying the tobacco, the moisture content of the exported tobacco can be effectively controlled.

[0027] As an option of the embodiment of the present application, determining the first control data from the historical tofu drying data includes: The historical wire-drying data is cleaned according to a preset electronic scale cumulative amount interval, and the processed historical wire-drying data is divided based on at least two control data thresholds to obtain at least two groups of sub-wire-drying data; The deviation value of each group of sub-filament drying data is calculated, and when any deviation value is less than a preset minimum deviation threshold, the first control data is determined according to the corresponding sub-filament drying data.

[0028] Specifically, when determining the first control data from the historical wire-baking data, the control terminal can clean the historical wire-baking data according to the preset electronic scale cumulative amount interval, for example but not limited to screening out from the historical wire-baking data all historical moments corresponding to the historical electronic scale cumulative amounts in the preset electronic scale cumulative amount interval, and all historical wire-baking data corresponding to each historical moment. The preset electronic scale cumulative amount interval can be set to [4000, 9000], and the historical wire-baking data corresponding to any historical moment with missing data in the historical wire-baking data after cleaning can also be eliminated to ensure the validity of the historical wire-baking data.

[0029] Next, after the historical wire-drying data is cleaned, the control terminal may further divide the processed historical wire-drying data based on at least two control data thresholds to obtain at least two groups of sub-wire-drying data, wherein the at least two control data thresholds may be, but are not limited to, multiple thresholds of dehumidification air door opening and multiple thresholds of hot air speed. For example, taking at least two control data thresholds including a first air door opening threshold, a second air door opening threshold, a third air door opening threshold, a first hot air speed threshold, a second hot air speed threshold and a third hot air speed threshold as an example, the processed historical wire-drying data may be divided into four groups of sub-wire-drying data; wherein, in the first group of sub-wire-drying data, all historical dehumidification air door openings may be less than the first air door opening threshold, and all historical hot air speeds may be less than the first air door opening threshold. all may be less than the first hot air speed threshold; all historical dehumidification air door openings in the second group of sub-wire drying data may be greater than or equal to the first air door opening threshold, and less than the second air door opening threshold, and all historical hot air speeds may be greater than or equal to the first hot air speed threshold, and less than the second hot air speed threshold; all historical dehumidification air door openings in the third group of sub-wire drying data may be greater than or equal to the second air door opening threshold, and less than the third air door opening threshold, and all historical hot air speeds may be greater than or equal to the second hot air speed threshold, and less than the third hot air speed threshold; all historical dehumidification air door openings in the fourth group of sub-wire drying data may be greater than or equal to the third air door opening threshold, and all historical hot air speeds may be greater than or equal to the third hot air speed threshold, and are not limited to this.

[0030] Then, after obtaining multiple groups of sub-drying wire data, the control terminal can also calculate the corresponding deviation value based on the multiple historical data contained in each group of sub-drying wire data, and when it is detected that any deviation value is less than the preset minimum deviation threshold, it indicates that the corresponding sub-drying wire data may meet the control conditions of the outlet tobacco moisture, and when it is determined that the historical duration of the sub-drying wire data meets the preset duration, and the historical hot air speed average of the sub-drying wire data is in the preset hot air speed range, the first control data is determined according to the multiple historical data in the sub-drying wire data. It can be understood that the multiple historical data contained in each group of sub-drying wire data can include but is not limited to multiple historical moments, and the historical tobacco temperature, historical outlet moisture, historical inlet moisture content (also understood as inlet moisture), historical hot air speed, historical dehumidification damper opening and historical ambient humidity corresponding to each historical moment, and is not limited thereto.

[0031] As another option of the embodiment of the present application, the historical tobacco drying data includes at least two historical moments, and the historical tobacco temperature and historical outlet moisture corresponding to each historical moment; Calculate the deviation value of each group of sub-drying wire data, including: Calculate the mean temperature of all historical tobacco cut temperatures and the mean moisture of all historical outlet moisture in each group of sub-drying cut tobacco data; Calculate the difference between each temperature mean and a preset temperature standard value to obtain a first difference, and normalize the first difference; The difference between each moisture mean and the preset moisture standard value is calculated to obtain a second difference, and the second difference corresponding to each group of sub-roasted wire data and the processed first difference are calculated based on the preset weight parameters to obtain a corresponding deviation value.

[0032] Specifically, when calculating the deviation value of each group of sub-drying wire data, the control terminal can respectively calculate the temperature mean of all historical tobacco temperatures in each group of sub-drying wire data, and the moisture mean of all historical outlet moisture. Then, the difference between the calculated temperature mean of each group of sub-drying wire data and the preset temperature standard value can be calculated to obtain the first difference. Taking into account that the outlet moisture has a higher priority than the tobacco temperature in production for moisture control, the first difference can also be normalized and stepped.

[0033] Here, the normalization method for the first difference may be, but is not limited to, referring to the following formula: In the above formula, It may be the first difference value corresponding to each group of sub-roasted wire data.

[0034] Next, after obtaining the mean moisture value of each group of sub-baked wire data, the control terminal can also perform a difference calculation between the mean moisture value of each group of sub-baked wire data and the preset moisture standard value to obtain a second difference, and perform a weighted sum calculation on the first difference and the second difference calculated for each group of sub-baked wire data based on a preset weight parameter to obtain a corresponding deviation value.

[0035] Here, the summation calculation method may be but is not limited to the following: In the above formula, It can be the deviation value of each group of sub-drying wire data. It can be the first difference of the corresponding sub-roasting data, It can be the second difference of the corresponding sub-drying data, 0.4 and 0.6 can be the preset weight parameters corresponding to the tobacco temperature and outlet moisture, and the preset weight parameters take into account that the outlet moisture has a higher priority than the tobacco temperature in production for moisture control.

[0036] As another option of the embodiment of the present application, the historical tofu drying data also includes the historical hot air speed and the historical dehumidification air door opening corresponding to each historical moment; Determining the first control data according to the corresponding sub-filament drying data includes: The average value of all historical moisture removal air door openings in the corresponding sub-fiber drying data is calculated to obtain the first moisture removal air door opening; Calculate the average of all historical hot air speeds in the corresponding sub-drying wire data to obtain the average hot air speed, and calculate the first hot air speed according to the average hot air speed, the average moisture value of the corresponding sub-drying wire data and the preset moisture standard value; The first moisture-removing air door opening and the first hot air speed are used as the first control data.

[0037] Specifically, when determining the first control data, the control terminal can also average all historical dehumidification air door openings in the corresponding sub-drying data to obtain a first dehumidification air door opening, and use the first dehumidification air door opening as the dehumidification air door opening in the first control data, so as to achieve effective control of the moisture content of the outlet tobacco by adjusting the dehumidification air door opening of the tobacco drying machine when the tobacco drying machine is in the dry end stage of tobacco drying.

[0038] Then, the control terminal can also calculate the average of all historical hot air speeds in the corresponding sub-cut-drying data to obtain the average hot air speed, and can substitute the average hot air speed, the moisture average of the corresponding sub-cut-drying data, and the preset moisture standard value into the preset hot air speed formula to calculate the first hot air speed. It can be understood that the first hot air speed can be used as the hot air speed in the first control data, so as to effectively control the moisture of the outlet tobacco by adjusting the hot air speed of the tobacco drying machine when the tobacco drying machine is in the dry end stage of tobacco drying.

[0039] Here, the preset hot air speed formula may be but is not limited to the following: In the above formula, It can be the first hot air speed, It can be the average value of hot air speed, It can be the average moisture value of the corresponding sub-baked wire data, It can be a preset moisture standard value.

[0040] As another option of the embodiment of the present application, after calculating the deviation value of each group of sub-drying wire data, the method further includes: When each deviation value is greater than or equal to the preset minimum deviation threshold, the average of all historical hot air speeds and the average of all historical dehumidification door openings in the historical tofu drying data are calculated respectively; The average of all historical hot air velocities and the average of all historical moisture exhaust damper openings are used as the first control data.

[0041] Specifically, after calculating the deviation value of each group of sub-drying data, when it is detected that each deviation value is greater than or equal to the preset minimum deviation threshold, in order to ensure the applicability of the first control data, the control terminal can also calculate the mean of all historical hot air speeds in the historical drying data, and use the mean of all historical hot air speeds as the hot air speed in the first control data, so as to achieve effective control of the moisture content of the outlet tobacco by adjusting the hot air speed of the tobacco drying machine when the tobacco drying machine is in the dry head stage of tobacco drying.

[0042] It can be understood that the control terminal can also calculate the average of all historical dehumidification air door openings in the historical tobacco drying data, and use the average of all historical dehumidification air door openings as the dehumidification air door opening in the first control data, so as to achieve effective control of the moisture content of the outlet tobacco by adjusting the dehumidification air door opening of the tobacco drying machine when the tobacco drying machine is in the dry end stage of tobacco drying.

[0043] It should be noted that, in the embodiment of the present application, after obtaining the first control data, the control terminal can also calculate the mean of all historical ambient humidity and the mean of all historical inlet moisture in the sub-baking data corresponding to the first control data, so as to facilitate subsequent adjustment and processing of the control data, and is not limited to this.

[0044] Step 104: Dry the shredded tobacco according to the first control data, and after the shredded tobacco is in a dry end stage, obtain at least two sets of shredded tobacco monitoring data based on preset time intervals.

[0045] Specifically, after determining the first control data, the control terminal can, but is not limited to, obtain the start-up state of the tobacco drying machine and the detected electronic scale data in real time, and when it is detected that the start-up state of the tobacco drying machine is start-up, the accumulated amount of the electronic scale is less than or equal to 5000, and the moisture content of the outlet tobacco is less than or equal to 10, it indicates that the tobacco drying machine is in the dry head stage of tobacco drying at this time, and then the tobacco can be dried according to the first control data, for example, according to the dehumidification air door opening and hot air speed in the first control data, the corresponding equipment is controlled to output, so that the dehumidification air door opening and hot air speed of the tobacco drying machine in the dry head stage are consistent with the first control data, and multiple groups of tobacco monitoring data of the tobacco drying machine can be obtained in real time based on the preset time interval. It can be understood that each group of tobacco monitoring data can include, but is not limited to, the outlet temperature and ambient humidity of the tobacco drying machine when the tobacco drying machine is performing tobacco drying, and the preset time interval can be, but is not limited to, 1 second, and is not limited thereto.

[0046] Step 106: Obtain second control data based on all tobacco monitoring data and the first control data, and perform tobacco drying according to the second control data.

[0047] Specifically, after the tobacco drying machine is in the dry head stage of drying the tobacco, the control terminal can, but is not limited to, obtain the inlet moisture of the tobacco in real time, and when it is detected that the inlet moisture of any tobacco is greater than a preset moisture threshold, it indicates that the current inlet moisture of the tobacco of the tobacco drying machine has reached the standard, and then multiple groups of tobacco monitoring data of the tobacco drying machine can be obtained in real time based on preset time intervals, and it can be determined whether the tobacco outlet temperature in each group of tobacco monitoring data exceeds the preset temperature threshold.

[0048] It is understandable that after obtaining the inlet moisture of the tobacco in real time, the embodiment of the present application can also determine whether the sum of the inlet moisture of each tobacco and the preset drying inlet zero value exceeds a preset value (for example, 17), so that when any summation result exceeds the preset value, multiple groups of tobacco monitoring data of the tobacco drying machine are obtained in real time based on a preset time interval. Here, the purpose of summing the inlet moisture of each tobacco with the preset drying inlet zero value is to accurately control the moisture of the tobacco and ensure its quality and process performance in subsequent processing links. The establishment of this condition is not only related to the basic physical properties of tobacco, but also closely related to the stability and efficiency of the entire production process.

[0049] First of all, the moisture content of tobacco has a decisive influence on its processing quality and the characteristics of the final product. If the moisture content is too high, it is easy to cause tobacco sticking, affecting separation and cutting operations, and reducing drying efficiency, and the energy consumption of the drying process will increase accordingly; on the other hand, tobacco with too low moisture content is easy to pulverize, which not only causes material loss, but also affects the processing quality of subsequent processes, such as aroma release and combustion performance. Therefore, it is particularly important to set a reasonable moisture control range, and exceeding the preset value (for example, 17) can avoid the above problems.

[0050] Secondly, the preset value (e.g. 17) is set based on long-term production experience and experimental data optimization, which not only covers the volatility of the raw materials themselves, but also comprehensively considers the influence of environmental humidity and temperature, ensuring that the drying process can adapt to changes in external conditions. At the same time, the introduction of the preset drying inlet zero value provides dynamic adjustment capabilities for the entire moisture control. The preset drying inlet zero value usually represents the reference point of the equipment or system, which can be used to calibrate the operating parameters, thereby compensating for minor deviations caused by equipment status and raw material differences, and further improving control accuracy.

[0051] Furthermore, when the outlet temperature of the tobacco in any group of tobacco monitoring data exceeds the preset temperature threshold, it indicates that the current tobacco temperature exceeds the standard (that is, the dehumidification air door opening needs to be adjusted in time), and then the dehumidification air door opening in the first control data (that is, the first dehumidification air door opening) can be adjusted based on the preset deviation opening. For example, the preset deviation opening and the dehumidification air door opening can be summed to obtain the second dehumidification air door opening. Here, after determining the second dehumidification air door opening, the control terminal can also directly adjust the tobacco drying machine according to the second dehumidification air door opening, so that the dehumidification air door opening of the tobacco drying machine at the current moment is consistent with the second dehumidification air door opening.

[0052] Furthermore, after obtaining the second damp air door opening, the control terminal can also count the total number of groups of all currently acquired tobacco monitoring data, and when the total number of groups exceeds the preset first group number threshold, it indicates that the amount of currently monitored environmental humidity data has reached the standard, and then the second hot air speed can be obtained based on the average of all historical environmental humidity in the historical drying data, the average of all historical environmental humidity corresponding to the first control data, and the first hot air speed. Here, the method for obtaining the second hot air speed can be, but is not limited to, referring to the following: In the above formula, Can be the second hot air speed, It can be the first hot air speed, It can be the average of all historical ambient humidity in the historical drying data. It may be the average value of all historical ambient humidity corresponding to the first control data.

[0053] After obtaining the second hot air speed, the control terminal can dry the tobacco according to the second hot air speed, so that the hot air speed of the tobacco drying machine in the drying stage is consistent with the second hot air speed.

[0054] It should be noted that the preset first group of number thresholds mentioned in the embodiment of the present application can be 100, so as to achieve a good balance between capturing the humidity change trend and ensuring the real-time adjustment. The preset first group of number thresholds can not only accurately reflect short-term fluctuations and long-term trends, but also avoid random errors caused by too little data and system response lags caused by too much data.

[0055] Since the current ambient humidity data reflects real-time and can capture immediate changes, while the average of historical humidity data reflects the long-term trend, taking the current ambient humidity as a benchmark and combining it with the historical average for proportional adjustment can better adapt to real-time needs, while ensuring the scientificity and stability of system adjustment, and avoiding random errors caused by insufficient data and adjustment delays caused by excessive data.

[0056] The moisture content of tobacco is directly related to product quality. Too dry tobacco will increase the breakage rate, while too wet tobacco will affect combustion performance and aroma release. Therefore, dynamic adjustment of hot air parameters is crucial for humidity regulation. Since humidity regulation has a lag, the effect of parameter adjustment takes a certain amount of time to appear. Too frequent adjustments will not only increase equipment loss, but may also reduce production efficiency. Research on a large amount of historical tobacco drying data shows that selecting 100 as the preset first group number threshold can effectively balance the timeliness of adjustment and the continuity of the process, ensuring that the adjustment process is scientific and reasonable.

[0057] In the batch production mode, the change of environmental humidity in each batch will affect the subsequent production links. Therefore, the accumulation of historical data should cover a complete production cycle or the key stage of a batch. 100 as the preset first group number threshold can fully reflect the humidity change in the current production batch and provide a reliable basis for the next parameter adjustment. Through experiments, it can be concluded that when the preset first group number threshold is less than 50, it is susceptible to instantaneous fluctuations, resulting in frequent and unnecessary adjustments; and when the preset first group number threshold exceeds 200, the system may ignore the current actual demand and cause adjustment lag.

[0058] In general, the dynamic adjustment method of selecting 100 as the preset first group of numerical thresholds can effectively balance real-time demand and long-term trends, and significantly improve the accuracy and stability of hot air parameter adjustment. This method realizes the intelligent upgrade of the tobacco processing process, while improving energy utilization efficiency and reducing equipment loss, providing reliable technical support for the stability and efficiency of tobacco processing.

[0059] It can also be understood that after adjusting the hot air speed of the tobacco drying machine according to the second hot air speed, the control terminal can also obtain the startup status of the tobacco drying machine and the detected electronic scale data in real time, and before the tobacco drying machine transitions from the dry head stage to the stable stage, the total number of groups of all tobacco monitoring data currently obtained is counted again, and when the total number of groups exceeds the preset second group number threshold, it indicates that the current monitored inlet moisture data has reached the standard, and then the third hot air speed can be obtained based on the average of all historical inlet moisture in the historical drying data, the average of all historical inlet moisture corresponding to the first control data, and the first hot air speed. Here, the method of obtaining the third hot air speed can be, but is not limited to, referring to the following: In the above formula, Can be the third hot air speed, It can be the first hot air speed, It can be the average of all historical inlet moisture in the historical drying data. It may be the average of all historical inlet moisture corresponding to the first control data.

[0060] After obtaining the third hot air speed, the control terminal can also dry the tobacco according to the third hot air speed so that the hot air speed of the tobacco drying machine in the dry head stage is consistent with the third hot air speed until the tobacco drying machine is in a stable stage.

[0061] It should be noted that the preset second group number threshold mentioned in the embodiment of the present application can be 300, which can provide a sufficiently representative sample to ensure the stability and credibility of the analysis results of tobacco product quality indicators or process parameters. In the tobacco production process, selecting 300 as the preset second group number threshold can usually capture the periodic laws of equipment operation status, raw material fluctuations and final product consistency, ensuring the real-time and accuracy of process optimization; secondly, industry practice shows that selecting 300 as the preset second group number threshold works well in tobacco quality testing and production process monitoring, and can reduce the time cost of long-term verification and adjustment; in addition, the design of tobacco industry equipment and data processing systems usually balances the data volume and storage processing costs. Selecting 300 as the preset second group number threshold can meet the analysis needs without putting too much pressure on resources.

[0062] The selection of 300 as the preset second set of numerical thresholds integrates statistical principles, process characteristics, industry experience and the economy of data collection. It can comprehensively reflect the changing trend of inlet moisture, capture the fluctuation patterns of raw materials, environment and equipment status, and provide a stable and reliable basis for adjustment. At the same time, through the cumulative fluctuation mean, the selection of 300 as the preset second set of numerical thresholds smoothes the impact of short-term anomalies, captures the characteristics under different production conditions, and enhances the adaptability to diversified production environments.

[0063] Step 108: After the tobacco is in the drying tail stage, third control data is obtained according to the duration of the tobacco in the drying tail stage and the second control data, and the tobacco is dried according to the third control data.

[0064] Specifically, the control terminal can, but is not limited to, obtain the startup status of the tobacco drying machine and the detected electronic scale data in real time, and when it is monitored that the startup status of the tobacco drying machine is startup, the accumulated amount of the electronic scale is less than or equal to 11,000, and the flow rate of the electronic scale is greater than or equal to 200, it indicates that the tobacco drying machine has now transitioned from the dry head stage to the stable stage, and can continuously obtain the outlet temperature of the tobacco drying machine and the outlet moisture content of the tobacco, and can adjust the opening of the dehumidification damper by judging whether the outlet temperature is within the normal range, and can also adjust the hot air speed by judging whether the outlet moisture content of the tobacco is within the normal range, so as to ensure the stability of the moisture content of the tobacco during the drying process in the stable stage.

[0065] Furthermore, the control terminal can also continuously and in real time obtain the startup status of the tobacco drying machine and the detected electronic scale data after the tobacco drying machine is in a stable stage, and when it is monitored that the startup status of the tobacco drying machine is startup, the accumulated amount of the electronic scale is greater than or equal to 11,000, and the flow rate of the electronic scale is less than or equal to 200, it indicates that the tobacco drying machine is currently in the drying tail stage, and the second control data can be adjusted according to the duration of the tobacco in the drying tail stage to obtain the third control data, and then the tobacco can be dried according to the third control data, so that the dehumidification damper opening and the hot air speed of the tobacco drying machine in the drying tail stage are consistent with the third control data until the tobacco drying process is completed.

[0066] It is understandable that when the duration of the tobacco in the drying tail stage is within the preset first duration interval, it indicates that the accumulated amount of the drying tail is 1 / 4 of the drying tail, and the second control data can be adjusted based on the preset first parameter to obtain the third control data. Here, the preset first duration interval can be 60 seconds to 120 seconds, and the preset first parameter can be, but is not limited to, 0.8 and 50. At this time, the dehumidification air door opening in the third control data is 50, and the hot air speed can be the product of the hot air speed in the second control data and 0.8.

[0067] It should be noted that during the drying process of tobacco production, the surface moisture of the tobacco evaporates quickly during drying, and the internal moisture needs time to migrate to the surface. Excessive hot air intensity will cause surface hardening, hinder the normal migration of internal moisture, and affect the flexibility and taste of the tobacco. At this time, reducing the hot air intensity to 80% can slow down the evaporation rate of surface moisture, making it closer to the migration rate of internal moisture, thereby achieving uniform moisture distribution and avoiding the problem of uneven drying. In addition, moderate hot air intensity helps to control the surface temperature of tobacco, reduce the loss of volatile aroma components, and protect the integrity of chemical components such as nicotine. Through multiple rounds of experiments and data analysis, an adjustment range of 80% has been verified to be effective, which can improve drying uniformity, stabilize the temperature and humidity environment, and maintain economic benefits.

[0068] The moisture exhaust damper opening in the third control data is set to 50, which can timely discharge the moisture generated by evaporation to prevent humidity accumulation from affecting the drying effect, while keeping the ambient humidity within a certain range to prevent the tobacco from dehydrating prematurely and causing quality loss. Through such adjustments, the local temperature can be effectively controlled, the chemical composition and physical structure integrity of the tobacco can be protected, and the product quality can be ensured.

[0069] When the duration of the tobacco in the drying tail stage is within the preset second duration interval, it indicates that the accumulated amount of the drying tail is 1 / 2 of the drying tail, and the second control data can be adjusted based on the preset second parameter to obtain the third control data. Here, the preset first duration interval can be 120 seconds to 180 seconds, and the preset second parameter can be, but is not limited to, 0.4 and 40. At this time, the dehumidification air door opening in the third control data is 40, and the hot air speed can be the product of the hot air speed in the second control data and 0.4.

[0070] It should also be noted that in the drying process of tobacco production, adjusting the hot air speed from the original 80% to 40% is a highly targeted process optimization measure aimed at achieving a more uniform drying effect while protecting the physical and chemical quality of the tobacco. By reducing the hot air speed, the rapid evaporation of surface moisture can be effectively slowed down, thereby avoiding the "hard shell effect", promoting the outward migration of internal moisture, and achieving overall drying uniformity. Moderately reducing the hot air intensity can also effectively control the local temperature, prevent the tobacco from charring or carbonizing, and ensure its structural integrity. In addition, a lower hot air speed can also maintain a certain humidity level, support the gradual migration of moisture, and avoid uneven drying. At the same time, this adjustment strategy helps to reduce the loss of volatile aroma components and nicotine, and maintain the aroma and flavor of the tobacco. Practice has proved that reducing the hot air speed to 40% has strong adaptability in different types of tobacco, which not only ensures the quality of the product, but also reduces energy consumption, thereby improving economic benefits.

[0071] Setting the dehumidification damper opening in the third control data to 40 degrees helps reduce moisture emissions, controls the humidity level in the system, and provides good temperature and humidity coordination conditions for the continued migration of moisture inside the tobacco, thereby maintaining uniform drying. At the same time, a smaller dehumidification damper opening can also moderately maintain a stable temperature, preventing the tobacco from losing its ideal physical state due to a rapid drop in temperature.

[0072] When the duration of the tobacco in the drying tail stage is within the preset third duration interval, it indicates that the accumulated amount of the drying tail is 3 / 4 of the drying tail, and the second control data can be adjusted based on the preset third parameter to obtain the third control data. Here, the preset third duration interval can be greater than 180 seconds, and the preset third parameter can be, but is not limited to, 1. At this time, the dehumidification air door opening in the third control data is the dehumidification air door opening in the second control data (or can be adjusted according to the target characteristics of the tobacco product), and the hot air speed can be the hot air speed in the second control data, but is not limited thereto.

[0073] It should also be noted that during the drying process of tobacco production, the hot air speed is restored to the hot air speed in the second control data in order to ensure the final removal of moisture. Rapid temperature rise can effectively accelerate the evaporation of residual moisture and prevent moisture from being retained inside the tobacco, thereby achieving thorough drying. At the same time, the moisture emission rate is moderately increased, and the humidity in the system is further reduced by restoring the dehumidification damper opening to the dehumidification damper opening in the second control data, so as to prevent the tobacco from absorbing external moisture and ensure that the dried tobacco can be quickly cooled without rehumidification. In addition, at this stage, reasonable adjustment of the hot air and dehumidification damper parameters can also help protect the aromatic substances and other chemical components in the drying process, prevent the loss of aroma caused by high temperature, and improve the release effect of the aroma of the finished product.

[0074] In one or more embodiments of the present application, the production control method for the dry head and dry tail of tobacco drying can significantly improve the control accuracy of tobacco moisture and ensure the consistency and stability of the product; at the same time, the production control method for the dry head and dry tail of tobacco drying can also optimize production efficiency, reduce adjustment time and frequency, and thus reduce energy consumption. In addition, the introduction of automated control reduces dependence on manual intervention, reduces the risk of human operational errors, and improves the safety and reliability of the production process. By effectively controlling the moisture distribution in the dry head and dry tail stages, the quality of the final product can be improved to meet the market demand for high-quality tobacco. In addition, the present application also provides technical support for the intelligent manufacturing transformation of the tobacco industry and promotes the digitalization and intelligent development of the production process.
