Description

Technical Field

[0001] The present application belongs to the field of tobacco processing and intelligent manufacturing technology, and in particular relates to a production control method and device for drying the end and beginning of cut tobacco. Background Art

[0002] In the tobacco processing industry, moisture control during the tobacco drying process significantly impacts the quality of the final product. Traditional methods for controlling moisture in tobacco cut tobacco rely primarily on manual monitoring and empirical judgment. These methods suffer from slow response times and inaccurate accuracy, making them difficult to adapt to the demands of modern intelligent production. With the continuous advancement of intelligent manufacturing technology, data-driven control approaches have become an important means of improving production efficiency and product quality. In recent years, the application of machine learning and data analysis technologies has increased significantly across various fields, particularly showing promising prospects in the modeling and control of complex systems. By analyzing historical production data and real-time monitoring information, effective predictive models can be constructed to dynamically monitor and adjust the tobacco drying process.

In addition, features described in some examples may be combined in other examples.

[0057] See also Figure 1 , Figure 1 The overall flow chart of a method for controlling the production of dried tobacco ends and dried ends provided in an embodiment of the present application is shown.

[0058] like Figure 1 As shown, the production control method for drying the end and end of cut tobacco may include at least the following steps:

[0059] Step 102: Obtain historical tobacco drying data, and determine first control data from the historical tobacco drying data.

[0060] 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, applied to a control terminal. The control terminal 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.

[0061] 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 (which can also be understood as inlet water content), the outlet temperature of the tobacco, and the ambient humidity. Each type of data can be collected by sensors or control devices installed at corresponding locations 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. The data may include, but is not limited to, historical tobacco temperature, historical outlet moisture content, historical inlet moisture content (which can also be understood as inlet moisture content), historical hot air speed, historical dehumidification damper opening, and historical ambient humidity at multiple historical moments. Each type of data can also be collected by sensors or control devices installed at corresponding locations and pre-stored in the control terminal. The historical drying data may also include, but is not limited to, historical inlet tobacco flow rate, historical ambient temperature, historical steam pressure, historical steam mass flow rate in different cylinder wall structures, and historical cylinder temperature.

[0062] 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, preparation stage, dry head stage, stable stage and dry tail stage. The startup 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 startup 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 judged in real time. Here, the start-up state of the tobacco drying machine in the non-production stage is not started, and the monitored cumulative amount on the electronic scale is less than 10; the start-up state of the tobacco drying machine in the preparation stage is started, and the monitored cumulative amount on the 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 monitored cumulative amount on 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; the stable stage can be understood as a stage where the tobacco is dried stably. The start-up state of the tobacco drying machine in the stable stage is started, the monitored cumulative amount on the electronic scale is less than or equal to 11000, and the electronic scale flow rate is greater than or equal to 200; the drying tail stage can be understood as a stage where the tobacco tail is not fully dried at the end of the drying process. The start-up state of the tobacco drying machine in the drying tail stage is started, the monitored cumulative amount on the electronic scale is greater than or equal to 11000, and the electronic scale flow rate is less than or equal to 200, and is not limited to this.

[0063] It can be understood that the control terminal obtains historical tobacco drying data, determines the first control data from the historical tobacco 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, based on all the tobacco monitoring data and the first control data, the second control data is obtained, 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 dry tail stage, the third control data is obtained based on the duration of the tobacco in the dry 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 dry tail stage by combining the duration, thereby ensuring the uniformity of moisture distribution of the tobacco and the stability of product quality throughout the 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.

[0064] Specifically, during tobacco drying, the control terminal can, but is not limited to, query a historical database for historical drying data corresponding to a tobacco batch currently being dried, and can determine first control data for controlling the moisture content of the exported tobacco from this historical drying data. Here, the historical database can include historical drying data corresponding to multiple tobacco batches, and the data types included in the historical drying data corresponding to each tobacco batch can be found in the above description. The determined first control data can be multiple types of data that are most strongly correlated with the moisture content of the exported tobacco, such as, but not limited to, the dehumidification damper opening and the hot air velocity. Specifically, by adjusting the dehumidification damper opening and the hot air velocity during tobacco drying in the tobacco drying machine, effective control of the moisture content of the exported tobacco can be achieved.

[0065] As an option in the embodiment of the present application, determining the first control data from the historical tow drying data includes:

[0066] The historical tow-bean drying data is cleaned according to a preset electronic scale cumulative amount interval, and the processed historical tow-bean drying data is divided based on at least two control data thresholds to obtain at least two groups of sub-tow-bean drying data;

[0067] The deviation value of each group of sub-cut wire 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-cut wire drying data.

[0068] Specifically, when determining the first control data from the historical wire-drying data, the control terminal can clean the historical wire-drying data according to the preset electronic scale cumulative amount interval, for example, but not limited to screening out all historical moments corresponding to the historical electronic scale cumulative amounts in the preset electronic scale cumulative amount interval from the historical wire-drying data, and all historical wire-drying data corresponding to each historical moment. The preset electronic scale cumulative amount interval can be set to [4000, 9000], and the historical wire-drying data corresponding to any historical moment with missing data in the historical wire-drying data after cleaning can also be eliminated to ensure the validity of the historical wire-drying data.

[0069] Then, after cleaning the historical wire-baking data, the control terminal may further divide the processed historical wire-baking data based on at least two control data thresholds to obtain at least two groups of sub-wire-baking data. The at least two control data thresholds may be, but are not limited to, multiple thresholds of dehumidification damper opening and multiple thresholds of hot air speed. For example, taking at least two control data thresholds including a first damper opening threshold, a second damper opening threshold, a third damper 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-baking data may be divided into four groups of sub-wire-baking data; wherein, in the first group of sub-wire-baking data, all historical dehumidification damper openings may be smaller than the first damper opening threshold, and all historical hot air speeds may be smaller than the first damper opening threshold. can all be less than the first hot air speed threshold; all historical dehumidification air door openings in the second group of sub-wire drying data can 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 can 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 can 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 can 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 can be greater than or equal to the third air door opening threshold, and all historical hot air speeds can be greater than or equal to the third hot air speed threshold, and are not limited to this.

[0070] Next, after obtaining multiple sets of sub-cut tobacco drying data, the control terminal may further calculate corresponding deviation values ​​based on the various historical data included in each set of sub-cut tobacco drying data. If any deviation value is detected to be less than a preset minimum deviation threshold, this indicates that the corresponding sub-cut tobacco drying data may meet the control conditions for outlet cut tobacco moisture. Furthermore, if it is determined that the historical duration of the sub-cut tobacco drying data meets a preset duration and that the historical average hot air velocity of the sub-cut tobacco drying data falls within a preset hot air velocity range, the control terminal may determine first control data based on the various historical data in the sub-cut tobacco drying data. It is understood that the various historical data included in each set of sub-cut tobacco drying data may include, but is not limited to, multiple historical moments, and the historical cut tobacco temperature, historical outlet moisture content, historical inlet moisture content (also understood as inlet moisture content), historical hot air velocity, historical dehumidification damper opening, and historical ambient humidity corresponding to each historical moment, and is not limited thereto.

[0071] As another option of the embodiment of the present application, the historical cut tobacco drying data includes at least two historical moments, and the historical cut tobacco temperature and historical outlet moisture corresponding to each historical moment;

[0072] Calculate the deviation value of each group of sub-tobake data, including:

[0073] Calculate the mean temperature value of all historical tobacco cut temperatures and the mean moisture value of all historical outlet moisture in each group of sub-cut tobacco drying data respectively;

[0074] Calculating the difference between each temperature mean and a preset temperature standard value to obtain a first difference, and normalizing the first difference;

[0075] The difference between each moisture mean and the preset moisture standard value is calculated to obtain the second difference, and the second difference corresponding to each group of sub-drying wire data and the processed first difference are calculated based on the preset weight parameters to obtain the corresponding deviation value.

[0076] Specifically, when calculating the deviation value of each group of sub-drying data, the control terminal can respectively calculate the temperature average of all historical tobacco temperatures in each group of sub-drying data, and the moisture average of all historical outlet moisture. Then, the difference between the temperature average calculated for each group of sub-drying data and the preset temperature standard value can be calculated to obtain a 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.

[0077] Here, the normalization method for the first difference may be, but is not limited to, referring to the following formula:

[0078]

[0079] In the above formula, It can be the first difference value corresponding to each group of sub-tobacco drying data.

[0080] Then, after obtaining the mean moisture value of each group of sub-drying wire data, the control terminal can also perform a difference calculation between the mean moisture value of each group of sub-drying 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-drying wire data based on the preset weight parameters to obtain a corresponding deviation value.

[0081] Here, the summation calculation method may be, but is not limited to, the following:

[0082]

[0083] 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-drying wire 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.

[0084] As another option in the embodiment of the present application, the historical tofu drying data further includes the historical hot air speed and the historical dehumidification door opening corresponding to each historical moment;

[0085] Determining first control data according to corresponding sub-filament drying data includes:

[0086] Calculate the average of all historical moisture removal air door openings in the corresponding sub-fiber drying data to obtain the first moisture removal air door opening;

[0087] Calculate the average of all historical hot air speeds in the corresponding sub-cut-widge drying data to obtain the average hot air speed, and calculate the first hot air speed based on the average hot air speed, the average moisture value of the corresponding sub-cut-widge drying data, and a preset moisture standard value;

[0088] The first row of damp air door opening and the first hot air speed are used as the first control data.

[0089] 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 the 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 head stage of tobacco drying.

[0090] The control terminal can then calculate the average of all historical hot air velocities in the corresponding sub-cut tobacco drying data to obtain an average hot air velocity. The control terminal can then substitute this average hot air velocity, the average moisture value of the corresponding sub-cut tobacco drying data, and a preset moisture standard value into a preset hot air velocity formula to calculate a first hot air velocity. It is understood that this first hot air velocity can be used as the hot air velocity in the first control data to effectively control the moisture content of the outlet cut tobacco by adjusting the hot air velocity of the cut tobacco drying machine when the cut tobacco drying machine is in the drying stage of the cut tobacco drying machine.

[0091] Here, the preset hot air speed formula may be but is not limited to the following:

[0092]

[0093] In the above formula, Can be the first hot air speed, It can be the average hot air speed, It can be the average moisture value of the corresponding sub-strip drying data, It can be a preset moisture standard value.

[0094] As another option of the embodiment of the present application, after calculating the deviation value of each group of sub-tobacco drying data, the method further includes:

[0095] When each deviation value is greater than or equal to the preset minimum deviation threshold, the average value of all historical hot air speeds and the average value of all historical dehumidification door openings in the historical tow drying data are calculated respectively;

[0096] The average value of all historical hot air velocities and the average value of all historical moisture exhaust damper openings are used as the first control data.

[0097] 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 average of all historical hot air speeds in the historical drying data, and use the average 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.

[0098] It can be understood that the control terminal can also calculate the average of all historical dehumidification damper openings in the historical tobacco drying data, and use the average of all historical dehumidification damper openings as the dehumidification damper opening in the first control data, so as to achieve effective control of the moisture content of the outlet tobacco by adjusting the dehumidification damper opening of the tobacco drying machine when the tobacco drying machine is in the dry head stage of tobacco drying.

[0099] 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 average of all historical ambient humidity and the average of all historical inlet moisture in the sub-wire drying 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.

[0100] Step 104: Dry the cut tobacco according to the first control data, and obtain at least two sets of cut tobacco monitoring data based on preset time intervals after the cut tobacco is in a dry end stage.

[0101] Specifically, after determining the first control data, the control terminal may, but is not limited to, acquire the startup status of the tobacco dryer and detected electronic scale data in real time. When the tobacco dryer startup status is detected as "startup," the accumulated electronic scale reading is less than or equal to 5000, and the outlet tobacco moisture is less than or equal to 10, the control terminal may determine that the tobacco dryer is in the final drying stage of tobacco drying. The control terminal may then dry the tobacco according to the first control data. For example, the control terminal may control the output of corresponding devices based on the dehumidification damper opening and hot air speed in the first control data, so that the dehumidification damper opening and hot air speed of the tobacco dryer in the final drying stage are consistent with the first control data. The control terminal may also acquire multiple sets of tobacco monitoring data from the tobacco dryer in real time based on preset time intervals. It is understood that each set of tobacco monitoring data may, but is not limited to, include the outlet tobacco temperature and ambient humidity of the tobacco dryer during tobacco drying. The preset time interval may, but is not limited to, 1 second.

[0102] 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.

[0103] 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 the preset moisture threshold, it indicates that the current inlet moisture of the tobacco of the tobacco drying machine has met the standard, and then multiple groups of tobacco monitoring data of the tobacco drying machine can be obtained in real time based on the preset time interval, and it can be determined whether the tobacco outlet temperature in each group of tobacco monitoring data exceeds the preset temperature threshold.

[0104] It is understood that after obtaining the inlet moisture of the tobacco cut in real time, the embodiment of the present application can also determine whether the sum of the inlet moisture of each tobacco cut and the preset inlet zero value of the cut tobacco cut exceeds a preset value (for example, 17). When any summed result exceeds the preset value, multiple sets of tobacco cut drying machine monitoring data are obtained in real time based on preset time intervals. Here, the purpose of summing the inlet moisture of each tobacco cut with the preset inlet zero value of the cut tobacco cut is to accurately control the moisture content of the tobacco cut, ensuring its quality and process performance in subsequent processing steps. The establishment of this condition is not only related to the basic physical properties of the tobacco cut, but also closely related to the stability and efficiency of the entire production process.

[0105] First, the moisture content of cut tobacco has a decisive influence on its processing quality and the characteristics of the final product. If the moisture content is too high, it can easily cause tobacco to stick together, hindering separation and cutting operations, reducing drying efficiency, and increasing energy consumption in the drying process. On the other hand, if the moisture content is too low, cut tobacco will easily become pulverized, resulting in material loss and affecting the processing quality of subsequent steps, 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 these problems.

[0106] Secondly, the preset value (e.g., 17) is optimized based on long-term production experience and experimental data. This not only accounts for raw material volatility but also takes into account the effects of ambient humidity and temperature, ensuring that the tow-bread drying process can adapt to changing external conditions. Furthermore, the introduction of a preset zero-point value at the tow-bread drying inlet provides dynamic adjustment capabilities for the entire moisture control process. This preset zero-point value typically represents a reference point for the equipment or system and can be used to calibrate operating parameters, compensating for minor deviations caused by equipment status and raw material differences, further improving control accuracy.

[0107] Furthermore, when the tobacco outlet temperature in any set of tobacco monitoring data exceeds a preset temperature threshold, it indicates that the current tobacco temperature exceeds the standard (i.e., the dehumidification damper opening needs to be adjusted in a timely manner). Based on the preset deviation opening, the dehumidification damper opening in the first control data (i.e., the first dehumidification damper opening) can be adjusted. For example, the preset deviation opening and the dehumidification damper opening can be summed to obtain a second dehumidification damper opening. Here, after determining the second dehumidification damper opening, the control terminal can also directly adjust the tobacco drying machine according to the second dehumidification damper opening so that the dehumidification damper opening of the tobacco drying machine at the current moment is consistent with the second dehumidification damper opening.

[0108] 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. When the total number of groups exceeds a preset first group number threshold, it indicates that the amount of currently monitored ambient humidity data has met the standard. The second hot air speed can then be obtained based on the average of all historical ambient humidity values ​​in the historical tobacco drying data, the average of all historical ambient humidity values ​​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:

[0109]

[0110] In the above formula, Can be the second hot air speed, Can be the first hot air speed, It can be the average of all historical ambient humidity in the historical tofu drying data. It may be the average of all historical ambient humidity values ​​corresponding to the first control data.

[0111] 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.

[0112] 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 humidity change trends and ensuring real-time adjustments. 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.

[0113] Since the current ambient humidity data reflects real-time characteristics and can capture immediate changes, while the average of historical humidity data reflects the long-term trend, using 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 scientific nature and stability of system adjustments, and avoiding random errors caused by insufficient data and adjustment lags caused by excessive data.

[0114] The moisture content of cut tobacco is directly related to product quality. Excessive dryness increases the breakage rate, while excessive moisture impairs combustion performance and aroma release. Therefore, dynamic adjustment of hot air parameters is crucial for humidity control. Due to the lag inherent in humidity control, the effects of parameter adjustments take time to manifest. Overly frequent adjustments not only increase equipment wear and tear but can also reduce production efficiency. A review of extensive historical tobacco drying data indicates that selecting 100 as the preset first threshold effectively balances timely adjustments with process continuity, ensuring a scientific and rational adjustment process.

[0115] In batch production, changes in ambient humidity within each batch impact subsequent production steps. Therefore, historical data should be accumulated to cover a complete production cycle or key stages of a batch. Using a preset first threshold of 100 accurately reflects humidity variations within the current production batch, providing a reliable basis for subsequent parameter adjustments. Experiments have shown that when the preset first threshold is less than 50, it is susceptible to transient fluctuations, leading to frequent and unnecessary adjustments. However, when the preset first threshold exceeds 200, the system may ignore actual demand, resulting in delayed adjustments.

[0116] Overall, the dynamic adjustment method, which uses 100 as the preset first threshold, effectively balances real-time demand with long-term trends, significantly improving the accuracy and stability of hot air parameter adjustment. This method achieves intelligent upgrades in tobacco processing, while improving energy efficiency and reducing equipment losses, providing reliable technical support for the stability and efficiency of tobacco processing.

[0117] It is also understandable 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 end stage to the stable stage, it can again count the total number of groups of all currently acquired tobacco monitoring data. When the total number of groups exceeds the preset second group number threshold, it indicates that the currently monitored inlet moisture data has met the standard. Then, based on the average of all historical inlet moisture values ​​in the historical drying data, the average of all historical inlet moisture values ​​corresponding to the first control data, and the first hot air speed, a third hot air speed can be obtained. Here, the method for obtaining the third hot air speed can be, but is not limited to, referring to the following:

[0118]

[0119] In the above formula, It can be the third hot air speed, Can be the first hot air speed, It can be the average of all historical inlet moisture in the historical drying data. It can be the average of all historical inlet moisture corresponding to the first control data.

[0120] 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.

[0121] It should be noted that the preset second set of number thresholds mentioned in the embodiments of this application can be 300, which can provide sufficiently representative samples to ensure the stability and reliability of the analysis results of tobacco product quality indicators or process parameters. In tobacco production processes, selecting 300 as the preset second set of number thresholds can generally capture the cyclical patterns of equipment operating status, raw material fluctuations, and final product consistency, ensuring the real-time and accurate optimization of processes. Secondly, industry practice has shown that selecting 300 as the preset second set of number thresholds is effective in tobacco quality testing and production process monitoring, reducing the time cost of long-term verification and adjustment. In addition, the design of tobacco industry equipment and data processing systems generally balances data volume with storage and processing costs. Selecting 300 as the preset second set of number thresholds can both meet analysis needs and not place excessive pressure on resources.

[0122] 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 various aspects such as raw materials, environment, and equipment status, and provide a stable and reliable basis for adjustment. At the same time, by accumulating the mean of fluctuations, 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.

[0123] 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.

[0124] 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 moisture content of the tobacco outlet, 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 moisture content of the tobacco outlet 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.

[0125] Furthermore, the control terminal can also continuously obtain the startup status of the tobacco dryer and the detected electronic scale data in real time after the tobacco dryer is in a stable stage, and when it is monitored that the startup status of the tobacco dryer 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 dryer 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 dryer in the drying tail stage are consistent with the third control data until the tobacco drying process is completed.

[0126] It is understood that when the duration of the tobacco in the tail drying stage is within a preset first duration range, it indicates that the accumulated amount of tail drying is 1 / 4 of the tail drying amount. The second control data can then be adjusted based on the preset first parameter to obtain the third control data. Here, the preset first duration range can be 60 seconds to 120 seconds, and the preset first parameter can be, but is not limited to, 0.8 and 50. In this case, the dehumidification damper 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.

[0127] 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 the 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, the 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.

[0128] Setting the damper opening in the third control data to 50 degrees effectively removes evaporative moisture, preventing accumulation that could affect drying efficiency. This also maintains ambient humidity within a certain range to prevent premature dehydration and quality loss of the tobacco. This adjustment effectively controls local temperature, protecting the chemical composition and physical integrity of the tobacco, and thus ensuring product quality.

[0129] When the duration of the tobacco in the tail-drying stage falls within a preset second duration range, indicating that the accumulated amount of tail-drying is 1 / 2 of the total tail-drying, the second control data can be adjusted based on the preset second parameter to obtain the third control data. Here, the preset first duration range can be 120 seconds to 180 seconds, and the preset second parameter can be, but is not limited to, 0.4 and 40. In this case, the dehumidification damper 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.

[0130] It's also worth noting that during the tobacco drying process, adjusting the hot air velocity from 80% to 40% is a highly targeted process optimization measure designed to achieve more uniform drying while protecting the physical and chemical quality of the cut tobacco. By reducing the hot air velocity, the rapid evaporation of surface moisture can be effectively slowed, thereby preventing the "crust effect" and promoting the outward migration of internal moisture, achieving overall drying uniformity. Moderately reducing the hot air intensity also effectively controls local temperatures, preventing charring or carbonization of the tobacco and safeguarding its structural integrity. Furthermore, a lower hot air velocity maintains a certain humidity level, supporting gradual moisture migration and avoiding uneven drying. Furthermore, this adjustment strategy helps minimize the loss of volatile aroma components and nicotine, preserving the aroma and flavor of the tobacco. Practice has proven that reducing the hot air velocity to 40% is highly adaptable to different types of cut tobacco, not only ensuring product quality but also reducing energy consumption and improving economic efficiency.

[0131] Setting the damper opening in the third control data to 40° helps reduce moisture emissions, controlling the humidity level within the system and providing optimal temperature-humidity coordination for continued moisture migration within the tobacco, thereby maintaining uniform drying. Furthermore, a smaller damper opening can maintain a moderately stable temperature, preventing the tobacco from losing its ideal physical state due to a rapid temperature drop.

[0132] When the duration of the tobacco tail drying phase is within a preset third duration interval, indicating that the accumulated amount of tail drying is 3 / 4 of the tail drying, the second control data can be adjusted based on the preset third parameter to obtain 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. In this case, the dehumidification damper opening in the third control data is the dehumidification damper opening in the second control data (or can be adjusted based on the target characteristics of the tobacco product), and the hot air speed can be, but is not limited to, the hot air speed in the second control data.

[0133] 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 increase 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, thereby preventing the tobacco from absorbing external moisture and ensuring 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 aromatic substances and other chemical components in the drying process, prevent aroma loss caused by high temperature, and improve the aroma release effect of the finished product.

[0134] In one or more embodiments of the present application, the production control method for the dried end and dried end of tobacco drying can significantly improve the control accuracy of tobacco moisture, ensuring the consistency and stability of the product; at the same time, the production control method for the dried end and dried end 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 dried end and dried end stages, the quality of the final product can be improved to meet the market demand for high-quality tobacco. In addition, this 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.
