Description

Technical Field

[0001] The present invention relates to the technical field of process regulation, and in particular to an automatic regulation method and system for a traditional Chinese medicine drying process. Background Art

[0002] The field of process control technology mainly involves the application of automation systems in various production processes to adjust and control various parameters in the production process, such as temperature, pressure, humidity, etc. The core goal is to improve production efficiency, ensure product quality and reduce the need for manual intervention through automatic adjustment mechanisms. Process control technology is widely used in food processing, chemical, pharmaceutical and other industries, especially in complex production processes, to optimize the entire process through precise parameter control to ensure that the product meets the predetermined standards. It usually includes sensors, controllers and actuators, and dynamically adjusts the production process through real-time monitoring and feedback mechanisms.

[0003] Among them, the automatic adjustment method for the drying process of Chinese medicinal materials is an automatic adjustment technology for the drying process in the production process of Chinese medicinal materials. The purpose is to automatically control key parameters such as temperature and humidity during the drying process to achieve the best drying effect. By using the automatic adjustment method, it can be ensured that Chinese medicinal materials retain their active ingredients and efficacy during the drying process, while avoiding overdrying or moisture residue, thereby improving the quality and production efficiency of Chinese medicinal materials, improving the accuracy and controllability of the drying process of Chinese medicinal materials, and optimizing the production process of Chinese medicinal materials.

[0004] In the traditional regulation of the drying process of Chinese medicinal materials, the adjustment of temperature and humidity often lags behind, making it difficult for Chinese medicinal materials to maintain a stable water removal rate during the drying process. Due to the technical failure to achieve a precise match between water evaporation and temperature and humidity regulation, it is easy to cause moisture retention or over-drying in local areas, affecting the efficacy and quality of the medicinal materials. At the same time, there is a lack of dynamic regulation capabilities at each stage of the drying process, resulting in the failure to optimize the regulation conditions at each stage according to actual needs. In addition, there is no personalized adjustment plan for the drying needs of different medicinal materials, and there is a lack of effective correction methods for the uneven distribution of temperature and humidity in the drying room. Therefore, there are obvious deficiencies in the uniformity of the drying effect and production efficiency, resulting in improper moisture management during the drying process and unstable quality of Chinese medicinal materials.

According to the real-time monitoring results, the real-time changes in the internal moisture of the Chinese medicinal materials are analyzed to confirm that the evaporation rate of the moisture of the Chinese medicinal materials is within a controllable range, and the drying requirements of each drying stage of the Chinese medicinal materials are matched accordingly to generate stage-by-stage temperature and humidity adjustment records; S5: According to the periodic temperature and humidity adjustment records, automatic calibration is performed after the Chinese medicinal materials drying cycle is completed to evaluate the difference between the actual water evaporation of the Chinese medicinal materials and the target drying process, adjust the control process of the drying process, avoid the loss of Chinese medicinal materials in the drying process, and generate the drying process control optimization results.

[0019] The basic data of drying environment include the amount of water evaporation, the analysis results of the trend of evaporation rate change and the correlation between evaporation rate and temperature and humidity; the heat and humidity distribution adjustment data include the heat distribution diagram, moisture diffusion rate and temperature and humidity distribution uniformity analysis results; the stage adjustment data of the Chinese medicinal materials drying process include the stage temperature and humidity adjustment plan, the water evaporation rate at different stages and the time interval of the drying stage; the stage temperature and humidity adjustment records include the stage temperature and humidity adjustment values, the moisture content at the end of the stage and the stage drying result analysis results; the drying process control optimization results include the drying process deviation analysis results, the adjusted temperature and humidity setting records, and the optimized drying process control parameter set.

[0020] See also Figure 2 , the steps to obtain the basic data of dry environment are: S111: The weight of the Chinese medicinal materials is monitored in real time through the weight sensor, and the moisture changes are recorded in combination with the timestamp, and the current moisture change is analyzed. Based on the comparison between the initial moisture data and the real-time data, the formula is used: ; Calculate the evaporation rate of water , generate water evaporation rate data, where, The quality of the medicinal materials at the current moment, is the quality of the medicinal materials at the initial moment, and are the time of the current moment and the initial moment respectively; At the point in time At 1 hour, the initial mass of the medicinal material is After 1 hour of drying, the water content of the medicinal material was reduced to gram.

[0021] Calculate the water evaporation rate according to the formula: ; The results show that within one hour, the water content of the medicinal material decreased by 10 grams, and the water evaporation rate was 10 grams per hour. This means that during the drying process, the medicinal material evaporated 10 grams of water per hour. By monitoring this water evaporation rate, it can provide a basis for adjusting the drying environment.

[0022] S112: combining the environmental temperature and humidity data, analyzing the correlation between the water evaporation rate data and the temperature and humidity changes, optimizing the matching between the evaporation rate and the environmental conditions, and generating a relationship model between the evaporation rate and the environmental conditions; When combining the ambient temperature and humidity data (temperature and humidity), first obtain the current ambient temperature and humidity data and compare it with the previously obtained water evaporation rate. For example, assuming the ambient temperature The ambient humidity is 25℃ and At this time, it is necessary to analyze the relationship between these temperature and humidity parameters and the water evaporation rate. First, calculate the relationship between the water evaporation rate and the ambient temperature and humidity difference, and set an evaporation coefficient , this coefficient is an empirical value obtained through experiments, such as setting . Then, the temperature and humidity of the current environment are combined with the previously obtained water evaporation rate, and the parameters are adjusted to optimize the water evaporation rate. Specifically, if the current evaporation rate is low, the evaporation process of water can be accelerated by increasing the ambient temperature or lowering the humidity, and vice versa. During the calculation and adjustment process, the adaptation relationship between the evaporation rate and the ambient temperature and humidity is gradually optimized by monitoring the changes in these data in real time. Finally, by repeatedly adjusting the temperature and humidity parameters, a model of the relationship between the evaporation rate and the environmental conditions is obtained, which is convenient for adjusting the subsequent drying process.

[0023] S113: Based on the relationship model between evaporation rate and environmental conditions, measure the temperature and humidity change range of the current environment, adjust the temperature and humidity parameters in the dry environment in real time, and dynamically generate basic data of the dry environment; Based on the relationship model between evaporation rate and environmental conditions, the temperature and humidity parameters are adjusted in real time. First, based on the obtained evaporation rate and the matching of environmental conditions, the evaporation of the medicinal materials is monitored in real time and analyzed. At this time, if it is found that the evaporation rate is lower than the expected target rate at a certain moment, the ambient temperature can be increased. Or reduce the ambient humidity To accelerate evaporation. The specific adjustment method is to first measure the temperature and humidity change range of the current environment, and then compare it with the previously set temperature and humidity range. According to the comparison results, the temperature is appropriately increased or the humidity change range is reduced so that the water evaporation rate reaches the set target value. If the humidity in the environment is too high, the humidity is gradually lowered to better support the evaporation of water; if the temperature is too low, the temperature is appropriately increased to enhance the evaporation capacity of water. The adjustment process requires multiple corrections through real-time monitoring equipment feedback to ensure that the match between temperature and humidity parameters and water evaporation rate is optimized. The basic data of the drying environment finally obtained in this process will provide continuous and stable control for the drying of medicinal materials.

[0024] See also Figure 3 , the steps for obtaining heat and moisture distribution adjustment data are: S211: The temperature, humidity and heat data of each area are obtained in real time through the temperature and humidity sensors in the drying room, the heat flow path is monitored and the temperature and humidity distribution of the different areas are recorded, using the formula: ; Calculating the moisture vapor diffusion rate , determine the flow speed and direction of moisture, and generate heat and moisture distribution data, where is the moisture diffusion coefficient, is the moisture concentration gradient; represents the moisture diffusion coefficient, which is usually determined experimentally or referenced to a standard value in the literature. Assume that the moisture diffusion coefficient measured in the drying room is , and the moisture concentration gradient The gradient indicating the change of moisture concentration with spatial position can be obtained by installing humidity sensors in various areas of the drying room.

[0025] If in a small space, the humidity concentration changes from Change to , and the length of this space is , then the concentration gradient Calculated as: ; Substitute the known parameters into the formula to calculate the moisture diffusion rate: ; The results show that the diffusion rate of moisture in this area is 1.3 times that of water per square meter per second. Grams reflects the flow and diffusion capacity of moisture, which can further evaluate the moisture distribution in the drying room and provide a basis for adjusting the humidity distribution.

[0026] S212: Calculate the temperature and humidity difference of each area according to the heat and humidity distribution data, and analyze the uniformity of temperature and humidity in each area. By comparing the moisture diffusion rate of the difference area, identify the area with uneven heat flow, and obtain the dry area analysis result; When combining the heat and humidity distribution data in the drying room, it is first necessary to comprehensively collect the moisture diffusion rate in different areas, compare the moisture flow speed in each area, record the moisture concentration gradient and calculate the specific value of moisture diffusion in each area. By installing a humidity sensor, the moisture concentration in each area can be obtained, and then the moisture diffusion rate can be calculated based on this data. These data will help identify areas where moisture diffusion is uneven in the drying room. For example, some areas may have poor moisture diffusion due to low temperature or high humidity. By comparing the changes in these moisture diffusion rates, the differences between regions can be found, and then the temperature and humidity differences can be calculated, and the relationship between moisture diffusion rate and temperature changes can be analyzed. Using these analysis results, improvement plans can be proposed for areas with uneven moisture diffusion. Finally, by calculating and comparing the relationship between moisture diffusion rate and temperature and humidity, data support is provided for adjusting the drying environment to ensure a more uniform moisture distribution.

[0027] S213: According to the drying area analysis results, the temperature and humidity control equipment in the drying room is manually adjusted in real time, the temperature and humidity changes in each area are continuously monitored, and the temperature and humidity distribution in each area of ​​the drying room is confirmed to be uniform, and the heat and humidity distribution adjustment data is generated; Based on the analysis results of the drying area, the temperature and humidity environment in the drying room is manually adjusted in real time. First, it is necessary to accurately control and adjust the temperature and humidity equipment in the drying room according to the temperature and humidity data of each area. During the adjustment process, the airflow and humidity distribution in the drying room are dynamically changed by gradually adjusting the speed of the fan, the output power of the heater, and the working state of the humidity control device. During the process, it is necessary to continuously monitor the changes in temperature and humidity in each area, and evaluate the adjustment effect by comparing the data changes before and after the adjustment. If the moisture diffusion rate in some areas still does not meet the requirements, it is necessary to further increase the wind speed or adjust the temperature of the heating equipment to accelerate the diffusion of moisture. The adjustment process requires real-time feedback data, and timely correct the operation strategy according to the changes in temperature and humidity to ensure that the temperature and humidity are evenly distributed in each area and achieve the ideal drying effect. Through continuous adjustment and monitoring, the heat and humidity distribution adjustment data is finally generated, providing a basis for future optimization of the drying environment.

[0028] See also Figure 4,The steps for obtaining the stage adjustment data of the Chinese medicinal materials drying process are: S311: Combine the basic data of drying environment and the heat and humidity distribution adjustment data to monitor and analyze the water evaporation of Chinese medicinal materials in the differential drying stage in real time, and generate staged water evaporation data based on the relationship between the change of temperature and humidity and the water evaporation rate; Combined with the temperature and humidity data of the drying environment, first obtain the real-time temperature and humidity data of the current drying stage, calculate the water evaporation rate of each area, and compare and analyze it with the ambient temperature and humidity, and adjust the temperature and humidity change rate according to actual needs. Specifically, according to the water evaporation rate of each drying stage, combined with the target evaporation rate, adjust the temperature and humidity settings of the equipment. For example, when the water evaporation rate is lower than the target value, the ambient temperature can be increased or the humidity can be reduced. These means can be used to increase the evaporation rate, and vice versa, corresponding adjustments can be made. This process requires dynamic tracking of the moisture diffusion rate and real-time adjustment of the fan, heater, and humidity control device to ensure that the water evaporation in each drying stage matches the environmental conditions. Through temperature and humidity adjustment, it is ultimately ensured that the moisture changes of the medicinal materials during the drying process meet expectations, and stage-by-stage adjustment data is generated to provide support for the adjustment and optimization of each stage in the drying process.

[0029] S312: Analyze the amplitude and direction of the current temperature and humidity changes according to the periodic water evaporation data, determine the matching degree between the water evaporation and the environmental conditions, judge whether it is necessary to adjust the temperature and humidity change rate of the drying environment, and generate dynamic adjustment data; By analyzing the actual data of water evaporation during the drying stage and comparing the results of ambient temperature and humidity, the moisture diffusion rate of each stage is calculated in real time, and the adjustment direction and amplitude of temperature and humidity are evaluated in combination with the target evaporation rate. If the moisture diffusion rate at a certain stage is lower than the target requirement, the ambient temperature or humidity is adjusted to increase the evaporation rate. For example, when the temperature is low or the humidity is too high, the ambient temperature can be increased or the fan can be accelerated to promote the evaporation of moisture. In this process, the temperature and humidity change rate is optimized according to the result data after each adjustment to ensure that the moisture evaporation rate at each stage meets the set target. Through continuous adjustment and optimization, evenly distributed temperature and humidity data are finally obtained to ensure that the drying effect reaches the expected goal.

[0030] S313: According to the dynamic adjustment data, the temperature and humidity change rate of the drying environment is manually adjusted in real time, the temperature and humidity changes in each area are continuously monitored, the water evaporation in each drying stage is accurately matched with the environmental conditions, and the stage adjustment data of the drying process of traditional Chinese medicine is generated; Based on the dynamic adjustment data, the temperature and humidity change rate of the drying environment is manually adjusted in real time. During the adjustment process, the staff monitors the moisture diffusion in each area in real time according to the temperature and humidity data, and adjusts the ambient temperature and humidity by manually controlling the drying equipment such as fans, heaters, and humidity controllers when necessary. During the real-time adjustment process, the staff must ensure that the moisture distribution in each area is uniform, and continue to track the impact of equipment adjustment on water evaporation to ensure that the evaporation rate meets the set target and that the water evaporation in each drying stage matches the environmental conditions. Through dynamic adjustment and real-time monitoring, the adjustment data for each drying stage is finally generated, and the subsequent drying process is optimized based on these data to achieve the best drying effect.

[0031] See also Figure 5 , the real-time monitoring steps for each drying stage are: S411: Based on the stage adjustment data of the drying process of traditional Chinese medicine, analyze the temperature and humidity changes in each drying stage, count the water evaporation rate in each stage, and adjust the working state of the temperature and humidity equipment in real time to match the ambient temperature and humidity setting requirements of each drying stage, and generate the adjusted temperature and humidity change data; According to the stage-by-stage adjustment data of the drying process of traditional Chinese medicine, it is first necessary to obtain the real-time temperature and humidity data of each drying stage and check the deviation from the target value. The water evaporation rate of each drying stage is obtained by calculating the relationship between the actual humidity change and time. If the water evaporation rate is lower than the expected target, the power of the heating equipment will be adjusted first, the ambient temperature will be increased, or the air flow will be accelerated by the fan to reduce the ambient humidity. In this process, it is also necessary to adjust the temperature and humidity change rate according to the information fed back by the equipment, and ensure that the water evaporation rate of each stage is close to the predetermined value by continuously adjusting the temperature and humidity environment. After each adjustment, it is necessary to re-monitor the temperature, humidity and water evaporation data to confirm whether the set target has been achieved, and record the adjustment results to provide a basis for subsequent adjustments to ensure that the water evaporation during the drying process is always within the control range.

[0032] S412: Based on the adjusted temperature and humidity data, monitor the changes in the ambient temperature and humidity in each drying stage in real time, verify the adjustment effect through real-time feedback data, and correct the drying environment settings to generate real-time monitoring data for each drying stage; On the basis of real-time adjustment data, manual real-time adjustment is performed to ensure that the temperature and humidity changes in each drying stage meet the set targets. In this process, the staff will first obtain the real-time data of each area through the temperature and humidity sensors, and intervene in the environmental equipment according to the adjusted data. For example, by adjusting the heating output of the heater, ensure that the temperature meets the set target; or by adjusting the operation of the humidity control device, ensure that the humidity changes are consistent with the target. When the monitoring data shows that the moisture evaporation rate in a certain area does not match the target, the staff intervenes according to the real-time feedback data, manually adjusts the speed of the fan and the working status of the humidity control device to ensure that the moisture diffusion rate is synchronized with the moisture evaporation rate. The whole process continues until the moisture evaporation in each drying stage matches the environmental conditions. The adjusted data will be recorded in real time and saved as a stage adjustment record, which further provides a basis for optimizing the drying environment.

[0033] S413: Based on the real-time monitoring data of each drying stage, manual adjustments are continuously made to each stage of the drying process, and the adjustment strategy is refined according to the characteristics of the differential drying stages, so as to maintain the uniformity of the temperature and humidity distribution and record the adjustment data, thereby generating real-time synchronous monitoring records; Based on the real-time monitoring data of each drying stage, the staff continues to make manual adjustments to each stage of the drying process. When adjusting, the staff first obtains the temperature and humidity data of the drying area through the monitoring equipment to check whether it is consistent with the set target. If the water evaporation rate in a certain area still does not meet expectations, the staff will intervene based on the data results and further adjust the operating status of the heating equipment or humidity control device. During the real-time adjustment process, the staff also needs to refine the adjustment strategy according to the characteristics of different drying stages, such as accelerating air flow or lowering the temperature, so as to maintain the uniformity of temperature and humidity distribution and ensure that the water evaporation rate remains within a controllable range. Through these adjustments, real-time synchronous monitoring records are finally generated to provide data support and optimization basis for the subsequent drying process.

[0034] See also Figure 6 , the steps for obtaining the staged temperature and humidity adjustment records are: 421: Analyze the moisture changes in the Chinese medicinal materials at each drying stage according to the real-time synchronous monitoring records, compare with the set target value, determine whether the moisture evaporation meets the requirements, analyze the reasons, and generate staged drying analysis results; According to the real-time synchronous monitoring records, it is first necessary to collect the temperature and humidity data of each drying stage and check the deviation from the preset target value. In order to better control the water evaporation rate, the relationship between humidity change and time is calculated to obtain the water evaporation rate of each stage. If the calculation results show that the water evaporation rate does not meet the target, it is necessary to adjust the current drying conditions. Specific operations include adjusting the heating output of the heater, increasing the temperature to accelerate water evaporation, or adjusting the air flow by the fan to reduce humidity, so that moisture is discharged faster. During the adjustment process, the staff will monitor the temperature and humidity changes in real time and record the results of each adjustment to ensure that the ambient temperature and humidity are consistent with the set target and that the water evaporation rate is within the control range. These operations will be based on the real-time data that is continuously collected to ensure that the water evaporation during the drying process is always in the optimal range.

[0035] 422: Confirm whether the water evaporation rate is within the controllable range through the staged drying analysis results, detect whether the water evaporation rate is too fast or too slow during the drying stage, dynamically adjust the operating status of the drying equipment according to demand, and promptly feedback the adjustment results to generate dynamic adjustment results; Based on the dynamic adjustment results, the staff makes dynamic adjustments in each drying stage. When the water evaporation rate does not meet expectations, the staff will re-evaluate the moisture diffusion in each drying area and further adjust the drying equipment based on real-time data. By detecting the difference between the water evaporation rate in different areas and the set target, the staff will take corresponding measures, such as increasing the temperature output of the heater or increasing the wind speed of the fan to help air circulation, thereby increasing the water evaporation rate. When adjusting the equipment, the staff also needs to ensure that the temperature and humidity are evenly distributed in each area to avoid local overheating or overhumidity, so as to ensure that the water evaporation in each drying stage meets the predetermined requirements. At each stage after the adjustment, the adjustment results are recorded and reference data is provided for the subsequent drying process.

[0036] 423: Based on the dynamic adjustment results, evaluate the temperature and humidity changes in each drying stage, check the deviation between the temperature and humidity data in each drying stage and the target value, make detailed adjustments simultaneously, and generate stage-by-stage temperature and humidity adjustment records; According to the dynamic adjustment results, the staff monitors the drying environment in real time and makes necessary adjustments according to the actual water evaporation. First, the staff needs to check the deviation of the temperature and humidity data from the target value in each drying stage, and determine whether the drying conditions need to be further optimized. If it is found that the water evaporation rate in a certain area deviates from the target, the corresponding equipment adjustment is made. For example, if the water evaporates too quickly, the staff may reduce the temperature output of the heater and lower the temperature to slow down the water evaporation; conversely, if the water evaporates too slowly, the temperature is increased and the air flow is accelerated to promote water evaporation. After each adjustment, the staff will continue to monitor the changes in temperature and humidity and record the adjustment results to ensure that the drying process at each stage proceeds smoothly. Finally, through continuous adjustment and monitoring, the staff will generate temperature and humidity adjustment records for each drying stage to ensure that the drying target can be achieved and the drying process remains efficient and consistent.

[0037] See also Figure 7 , the steps to obtain the optimization results of drying process control are: S511: Based on the periodic temperature and humidity adjustment records, collect and analyze the data after the drying cycle of Chinese medicinal materials, and count the temperature and humidity changes and evaporation rate at each stage of the drying process, using the formula: ; Calculates the percentage difference between the actual evaporation rate and the target drying process setpoint , and the difference analysis results of the drying stage were obtained, among which, represents the target water evaporation rate, Represents the actual measured water evaporation rate; Target water evaporation rate The actual measured water evaporation rate is 30 g / h 25 g / hour.

[0038] Plug into the formula: ; The results show that there is a difference of about 16.67% between the actual water evaporation rate and the target setting value. There is a certain deviation between the actual water evaporation rate and the target drying process setting value, and the control process needs to be further adjusted to optimize the drying effect.

[0039] S512: Combine the stage temperature and humidity adjustment records and the drying stage difference analysis results to evaluate the control effect of the current drying process, detect the temperature and humidity deviations and analyze the impact on the water evaporation rate, dynamically adjust the temperature and humidity change rate according to the actual differences, and obtain updated drying process control parameters; Combined with the stage-by-stage temperature and humidity adjustment records and the results of the difference analysis of the drying stages, we first collect real-time temperature and humidity data during the drying process, and conduct a detailed analysis of the temperature and humidity changes in different drying stages. According to the different drying stages, the temperature and humidity control strategy needs to be dynamically adjusted according to the characteristics of the stage. The collected temperature and humidity data can be used for subsequent deviation detection and correction. By comparing the theoretical value with the actual measurement value, the temperature and humidity deviation in the drying process is determined, and the temperature and humidity control effect of each stage is evaluated. The key factors affecting the water evaporation rate are further determined. The data are regressed and analyzed using statistical methods to obtain the relationship between temperature and humidity changes and water evaporation rate, thereby providing theoretical support for the next step of drying process optimization. On this basis, the influence of different stages in the drying process control process on water evaporation is analyzed, and the drying process control parameters are optimized by dynamically adjusting the temperature and humidity change rate. The control effect is evaluated using existing data to obtain the final drying process adjustment plan to ensure that the optimal water evaporation rate is maintained at each stage, and the changes in temperature and humidity are continuously monitored, and finally the control parameters are optimized and updated.

[0040] S513: according to the updated drying process control parameters, an automatic calibration process is executed, and the water evaporation of the entire drying process is monitored to ensure that the water evaporation of the Chinese medicinal materials during the drying process is kept within a controllable range, and a drying process control optimization result is generated; According to the updated drying process control parameters, the calibration process of the drying process is first executed. The calibration process requires real-time collection of the deviation between the actual value and the target value of each parameter in the drying process, and adjustment through the feedback control system to ensure that the drying parameters fluctuate within a reasonable range. The entire process is further analyzed in detail through the data of the humidity and temperature monitoring sensors to confirm the compliance of the current drying environment with the set target, and real-time correction is performed according to the monitoring data. During the calibration process, the system will correct the data for areas with large deviations, adjust the heating power and humidity control threshold, and ensure stable operation of the system. The calibration results will be fed back in real time, so as to automatically adjust the control parameters for optimization. Finally, the drying process control optimization results are generated through the data analysis tool. The results show the actual changes of various parameters in the drying process, and the adjusted control parameters are used to further verify whether the water evaporation rate meets expectations, thereby ensuring that the entire drying process is within the control range and achieving the optimization goal.
