Description

Technical Field

[0001] This invention relates to the field of preparation process control, and in particular to an intelligent preparation method for a kidney-tonifying and hair-growth medicinal wine. Background Technology

[0002] Kidney-tonifying and hair-growth-promoting medicinal wine is a type of Chinese medicinal wine prepared from various Chinese medicinal herbs through processes such as extraction, concentration, blending, and aging. It has the effects of tonifying the kidneys and replenishing qi, promoting blood circulation and dispelling wind.

[0003] Currently, the production of kidney-tonifying and hair-growth-promoting medicinal wines mainly relies on traditional pharmaceutical processes and manual experience. In the extraction stage, the decoction process is typically carried out with fixed durations and water additions, making dynamic adjustments difficult based on the characteristics of the medicinal materials and the actual conditions during decoction. In the percolation process, the soaking time and percolation speed are mostly set manually, failing to respond in real-time to changes in ambient temperature and equipment status. In the concentration stage, the determination of the concentration endpoint relies on manual sampling and density testing, resulting in detection lag and human error. In the aging stage, the determination of the aging endpoint usually depends on visual observation and experience-based estimation by operators, lacking quantitative standards. These problems lead to poor batch-to-batch consistency, large fluctuations in product quality, and high reliance on manual labor in the production of kidney-tonifying and hair-growth-promoting medicinal wines, making it difficult to meet the requirements of modern Chinese medicine production for quality stability and data traceability.

[0004] Therefore, it is evident that how to achieve intelligent control of the entire process of preparing kidney-tonifying and hair-growth medicinal wine has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an intelligent preparation method for a kidney-tonifying and hair-growth-promoting medicinal wine, which adopts the following technical solution: The first traditional Chinese medicine composition is weighed according to the prescription ratio and put into the decoction and extraction unit. The first monitoring data during the decoction and extraction process is acquired in real time. Based on the first monitoring data, the water replenishment, heating power and decoction time are dynamically adjusted. The decoction liquids from the two decoctions are combined and sent to the first concentration unit. After decompression concentration, the first concentrate is obtained. The second Chinese herbal composition is weighed according to the prescription ratio and then crushed into coarse powder. The coarse powder is put into the percolation extraction unit, and the second monitoring data during the percolation extraction process is acquired in real time. Based on the second monitoring data, the soaking time and percolation speed are dynamically adjusted to obtain the initial percolate and the subsequent percolate. The subsequent percolate is sent to the second concentration unit and concentrated under reduced pressure to obtain the second concentrate. The first concentrate and the second concentrate are added to the initial filtrate in sequence to obtain the initial mixed solution. The alcohol content of the initial mixed solution is adjusted to the preset target alcohol content to obtain the mixed solution. The mixed medicine solution is delivered to the aging unit, and the third monitoring data during the aging process is acquired in real time. Based on the third monitoring data, the aging completion time is determined. After aging, the mixed medicinal liquid is filtered and packaged to obtain the finished target medicinal wine.

[0007] Preferably, the decoction extraction unit is equipped with a decoction temperature sensor, a decoction level sensor, a decoction density sensor, and a pH electrode sensor; the first monitoring data includes: real-time temperature of the decoction, real-time level of the decoction, real-time density of the decoction, and real-time pH value of the decoction.

[0008] Preferably, the step of dynamically adjusting the water replenishment amount, heating power, and simmering time based on the first monitoring data includes: The water replenishment volume is adjusted using a preset interval judgment logic rule. The interval judgment logic rule is set as follows: the control interval is divided according to the relationship between the real-time liquid level of the decoction and the highest allowable liquid level, the lowest allowable liquid level, and the target liquid level of the decoction. The opening of the water replenishment valve is adjusted according to the control interval so that the real-time liquid level of the decoction can quickly reach the target liquid level of the decoction. A PID controller is used to adjust the heating power during decoction, so that the real-time temperature of the decoction liquid is maintained within the preset target constant temperature range. According to the preset decoction timing rules, the decoction time is adjusted. The decoction timing rules are set as follows: the effective decoction time is accumulated only when the real-time liquid level of the decoction is not less than the minimum allowable liquid level of the decoction and the real-time temperature of the decoction is not less than the minimum value of the target constant temperature range of the decoction. When the effective decoction time reaches the preset basic decoction time, the basic decoction time is extended according to the preset time if the real-time density of the decoction is less than the preset relative density threshold of the decoction or the real-time pH value of the decoction is less than the preset lower limit of the normal pH value range of the decoction.

[0009] Preferably, the first concentration unit includes a vacuum concentration tank, which is connected to an automatic vacuum adjustment device and an automatic temperature adjustment device. The automatic vacuum adjustment device and the automatic temperature adjustment device automatically adjust the vacuum degree and heating power of the vacuum concentration tank according to the real-time feedback signal of the first concentrate density sensor.

[0010] Preferably, the percolation extraction unit is equipped with a percolate temperature sensor, a percolate pressure sensor, a percolate density sensor, and a flow sensor; the second monitoring data includes: real-time percolate temperature, real-time pressure difference of the packing layer, real-time percolate density, and real-time percolate flow rate.

[0011] Preferably, the step of dynamically adjusting the impregnation time and percolation rate based on the second monitoring data includes: A preset temperature-compensated immersion time adjustment strategy is adopted to dynamically adjust the preset base immersion time. The temperature-compensated immersion time adjustment strategy is set to extend the base immersion time through a pre-calibrated piecewise linear compensation model when the real-time temperature of the permeate is less than the minimum value of the standard immersion temperature range, and shorten the base immersion time through a piecewise linear compensation model when the real-time temperature of the permeate is greater than the maximum value of the standard immersion temperature range. Based on the real-time pressure difference of the packing layer and the preset safe pressure difference range of the packing layer, the preset benchmark percolation velocity is dynamically adjusted. When the real-time pressure difference of the packing layer is less than the minimum value of the safe pressure difference range of the packing layer, the percolation velocity is increased according to the preset first linear curve. When the real-time pressure difference of the packing layer is greater than the maximum value of the safe pressure difference range of the packing layer, the percolation velocity is decreased according to the preset second linear curve.

[0012] Preferably, the second concentration unit includes a thin-film evaporator, which is connected to an automatic feed and discharge control system and a second concentrate density sensor. The automatic discharge control system automatically discharges the concentrate based on the real-time feedback signal from the second concentrate density sensor.

[0013] Preferably, the aging unit includes multiple aging tanks arranged in parallel, and each aging tank is equipped with an online turbidity detector and a sediment image recognition system; Real-time acquisition of third-party monitoring data during the aging process; determination of aging completion time based on this data, including: The sediment image recognition system uses a high-definition camera to capture cross-sectional images of the liquid in the aging tank and inputs these images into a pre-built image recognition model to obtain sediment distribution characteristics, including sediment percentage and floc dispersion density. The aging completion time was determined based on the distribution characteristics of the sediment and the turbidity of the supernatant collected by the online turbidity detector.

[0014] Preferably, determining the aging completion time based on the distribution characteristics of the sediment and the turbidity of the supernatant collected by an online turbidity detector includes: When the proportion of sediment exceeds the preset sediment proportion threshold and the absolute value of the rate of change of sediment proportion within a consecutive preset time period does not exceed the preset first rate of change threshold, the first separation signal is triggered. When the floc dispersion density is less than the preset dispersion density threshold and the absolute value of the rate of change of the floc dispersion density within a continuous preset time period is not greater than the preset second rate of change threshold, the second separation signal is triggered. When the turbidity of the supernatant collected by the online turbidity detector is less than the preset turbidity threshold and the absolute value of the rate of change of the supernatant turbidity within a continuous preset time period is not greater than the preset third rate of change threshold, the third separation signal is triggered. If at least two of the first separation signal, second separation signal, and third separation signal are detected to be in an effective holding state, the aging process is determined to be complete, and the current time point is recorded as the aging completion time.

[0015] This invention provides an intelligent preparation method for a kidney-tonifying and hair-growth-promoting medicinal wine, which has the following technical advantages compared to existing technologies: The intelligent preparation method for kidney-tonifying and hair-growth medicinal wine provided by this invention achieves fully automated production of decoction, percolation, concentration, blending, aging, and filtration and bottling through multi-sensor online detection and closed-loop control by a central controller, significantly reducing reliance on operator experience. Each process uses real-time detection data as the control basis. The decoction stage uses effective decoction time and density / pH dual parameters to determine the endpoint; the concentration stage uses online density triggering for automatic discharge; the blending stage uses real-time alcohol concentration feedback to accurately calculate the amount to be added; and the aging stage uses multi-parameter redundant logic to determine the endpoint, effectively eliminating batch-to-batch quality differences. An industrial IoT platform uniformly collects and stores process parameters for each process, forming a complete electronic batch record and improving data integrity. The control logic for each process can adaptively adjust parameters according to the characteristics of different batches of medicinal materials, making it suitable for the production needs of medicinal materials from different sources and in different batches, and has good prospects for industrial application.

[0016] Figure 1 This is a flowchart of an intelligent preparation method for a kidney-tonifying and hair-growth medicinal wine according to an embodiment of the present invention. Detailed Implementation

[0017] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. The embodiments are provided for illustrative purposes only and should not be construed as limiting the scope of the invention. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of protection of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of this invention.

[0018] In the description of this invention, it should be noted that, unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing specific embodiments only and is not intended to limit the invention. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] This invention discloses an intelligent preparation method for a kidney-tonifying and hair-growth-promoting medicinal wine, referring to... Figure 1 The flowchart shown is a method for intelligent preparation of a kidney-tonifying and hair-growth-promoting medicinal wine, including steps S1-S5, as detailed below: S1: Weigh the first Chinese herbal medicine composition according to the prescription ratio and put it into the decoction and extraction unit. The first monitoring data during the decoction and extraction process is obtained in real time. Based on the first monitoring data, the water replenishment, heating power and decoction time are dynamically adjusted. The decoction liquids from the two decoctions are combined and sent to the first concentration unit. After decompression concentration, the first concentrate is obtained.

[0020] It should be noted that the intelligent preparation method of the kidney-tonifying and hair-growth medicinal wine of the present invention is based on the Internet of Things intelligent control system to realize the fully automated closed-loop production process. The Internet of Things intelligent control system includes: intelligent acquisition terminal, execution drive module, online detection module and central controller.

[0021] The prescription for producing a kidney-tonifying and hair-growth-promoting medicinal wine of this invention comprises 16 Chinese medicinal herbs: Astragalus membranaceus, Rehmannia glutinosa (processed), Lycium barbarum, Longan aril, Glycyrrhiza uralensis, Poria cocos, Angelica sinensis, Polygonum multiflorum (processed), Salvia miltiorrhiza, Carthamus tinctorius, Ligustrum lucidum, Epimedium brevicornu, Eucommia ulmoides, Tribulus terrestris, Angelica dahurica, and Eclipta prostrata. The 16 herbs are divided into two groups. The first group comprises Astragalus membranaceus, Rehmannia glutinosa (processed), Lycium barbarum, Longan aril, Glycyrrhiza uralensis, and Poria cocos, and is extracted using a decoction extraction process. The second group comprises Angelica sinensis, Polygonum multiflorum (processed), Salvia miltiorrhiza, Carthamus tinctorius, Ligustrum lucidum, Epimedium brevicornu, Eucommia ulmoides, Tribulus terrestris, Angelica dahurica, and Eclipta prostrata, and is extracted using a percolation extraction process.

[0022] The decoction extraction process includes a decoction extraction unit, a decoction merging unit, a first filtration unit, and a first concentration unit. The decoction extraction unit includes a decoction tank, a water replenishment device, a purified water storage tank, a condenser reflux device, and a discharge valve. The decoction tank is a sealed container with a jacketed heating device. The tank is equipped with online monitoring devices such as a decoction temperature sensor, a decoction level sensor, a decoction density sensor, and a pH electrode sensor. The decoction temperature sensor is installed in the immersion zone in the middle of the tank to collect the real-time temperature of the decoction. The decoction level sensor uses a radar or ultrasonic non-contact level gauge, installed on the top of the tank. It measures the real-time level of the decoction by emitting a beam towards the surface of the decoction and receiving the echo, calculating the time difference between the emission and reception of the beam; alternatively, a differential pressure level gauge is used, installed at the bottom of the side wall of the tank, and the real-time level of the decoction is calculated by measuring the static pressure at the bottom of the tank. Because medicinal particles may clog the sensor during the decoction process, a circulation pipeline is installed at the bottom of the tank. A circulation pump draws the decoction liquid out, passes it through the decoction liquid density sensor, and then returns it to the tank, forming a bypass online detection loop to collect the real-time density of the decoction liquid. A filter screen is installed in front of the decoction liquid density sensor to prevent dregs from entering. The pH electrode sensor is installed on the circulation pipeline, downstream of the decoction liquid density sensor, and also has a filter screen in front of it to collect the real-time pH value of the decoction liquid.

[0023] The signals from each sensor are processed by the signal conditioning module (including amplification, filtering and A / D conversion circuits) and then transmitted to the intelligent acquisition terminal. The intelligent acquisition terminal is connected to the central controller and generates relevant control commands after performing relevant calculations.

[0024] Specifically, regarding the adjustment of water replenishment, the system presets the maximum allowable liquid level of the decoction, the minimum allowable liquid level of the decoction, the target liquid level of the decoction, the upper limit of the decoction heating power, the sampling period, and the control period. The maximum allowable liquid level of the decoction is set according to the upper limit of the tank volume safety, preferably 85% to 90% of the effective volume of the tank. The minimum allowable liquid level of the decoction is set according to the minimum amount of water required for complete saturation of the first herbal composition. The target liquid level of the decoction is the midpoint between the maximum allowable liquid level and the minimum allowable liquid level of the decoction. The upper limit of the decoction heating power is the maximum allowable heating power of the jacketed heating device of the decoction tank. The sampling period of each sensor in this invention is 1 to 3 seconds, and the adjustment period of the control command output by the central controller is 5 to 10 seconds.

[0025] Furthermore, the central controller incorporates a decoction liquid level controller. This controller employs a four-level interval judgment logic, using the comparison result between the real-time decoction liquid level and the maximum, minimum, and target levels of the decoction liquid as input. The output, based on the following four-level interval judgment logic rules, includes a water supply valve opening control command and a decoction heating power limiting command: First control range: when At this time, the central controller sends a shut-off command to the water supply valve to stop water supply; simultaneously, it sends a first cooking heating power limiting command to the cooking heating power controller built into the central controller, forcibly reducing the upper limit of the cooking heating power by a first percentage to prevent excessive heating power from aggravating boiling and overflow when the liquid level is too high. The first percentage is preferably 10%.

[0026] Second control range: when At this time, the current liquid level is slightly high but still within a safe range. The central controller controls the water replenishment valve to replenish water quantitatively within the first opening range; the heating power for boiling remains at normal power without any limit adjustment. The first opening range is preferably 10%-20%.

[0027] Third regulatory range: when At this time, the current liquid level is low but still meets the requirements for boiling. The central controller controls the water replenishment valve to replenish water quantitatively within the second opening range, while the heating power remains at normal power without any limit adjustment. The second opening range is preferably 20%-40%.

[0028] Fourth control range: when If the current liquid level is below the safety limit, the decoction may not completely soak the medicinal materials, posing a risk of dry burning. The central controller will control the water supply valve to continuously replenish water at the third opening range until the liquid level rises back to the required level. The above; at the same time, a second decoction heating power limiting command is sent to the decoction heating power controller to forcibly reduce the upper limit of the decoction heating power by a second percentage to prevent dry burning that could cause the medicinal materials to char or damage the equipment. The second percentage is preferably 30%, and the third opening range is preferably 60%-100%.

[0029] in, This indicates the real-time liquid level of the decocted medicine. This indicates the preset maximum allowable liquid level for the decoction. This indicates the preset minimum allowable liquid level for decoction. This indicates the target liquid level for the decoction.

[0030] It should be noted that the reduction of the upper limit of the frying and cooking heating power is achieved in the following way: the central controller sends a frying and cooking heating power limiting command to the frying and cooking heating power controller, thereby reducing the upper limit of the frying and cooking heating power of the controller to [a lower limit]. ,in, The percentage reduction includes both the first and second percentages. This is the upper limit of the heating power for frying and boiling.

[0031] Once the real-time liquid level of the decoction drops back to a safe range, the central controller sends either a command to release the first or second decoction heating power limit, with the command from the temperature control loop taking precedence.

[0032] For adjusting the heating power during frying, a target constant temperature range for frying is preset. The target constant temperature range for decoction corresponds to the state of slight boiling of the medicinal liquid, such as 98℃~100℃.

[0033] Specifically, a standard heating power for decoction is preset. The standard heating power is the average heating power required to maintain the decoction in a state of slight boiling, which is obtained through experimental calibration.

[0034] The central controller has a built-in decoction temperature controller, which is specifically a PID controller. It takes the deviation between the real-time temperature of the decoction and the target constant temperature range as input and the heating power adjustment as output. The control logic is as follows: when At that time, calculate the deviation at temperature. The change in the value of the heating power is calculated using a positional PID algorithm. in, express The temperature of the decoction should be monitored at all times during the decoction process. express The amount of power increased during constant frying and heating. This represents the first proportional coefficient preset by the PID controller. This represents the first integral coefficient of the PID controller. This represents the first derivative coefficient of the PID controller.

[0035] Based on the standard heating power for frying, the first heating power for frying is output: in, This indicates the standard heating power for frying and boiling. This indicates the initial heating power for frying or boiling.

[0036] when At the same time, maintain the standard heating power for frying; when When calculating temperature deviation The change in power and the positional PID algorithm are used to calculate the decrease in heating power. in, express Reduce the amount of heat used for constant frying and heating. This represents the second proportional coefficient of the PID controller. This represents the second integral coefficient of the PID controller. This represents the second derivative coefficient of the PID controller.

[0037] Based on the standard heating power for frying and boiling, a second heating power is output: in, This indicates the second heating power for frying and boiling.

[0038] The decoction time is adjusted by pre-calibrating the basic decoction time, the relative density threshold of the decoction, and the normal pH range of the decoction using traditional decoction techniques. In this invention, the basic decoction time is 60 minutes; the relative density threshold of the decoction reflects the lower limit of the density at which the effective components dissolve during normal decoction, and the normal pH range of the decoction reflects the acidity or alkalinity range of the decoction during normal decoction. The preferred relative density threshold of the decoction is 1.05 (measured at 100℃), and the preferred normal pH range of the decoction is... .

[0039] Traditional decoction processes are timed according to a clock, but in actual decoction, the extraction efficiency of active ingredients differs greatly between the heating phase, which deviates from the target constant temperature range, and the target constant temperature phase. This invention introduces an effective decoction time, which is accumulated only when the real-time liquid level of the decoction is not lower than the minimum allowable liquid level and the real-time temperature of the decoction is not lower than the minimum value of the target constant temperature range.

[0040] The effective decoction time is accumulated to obtain the real-time effective decoction time. The real-time effective decoction time is compared with the basic decoction time. When the real-time effective decoction time is equal to or greater than the basic decoction time, the process proceeds to the final verification stage. like and If the conditions for terminating the decoction are met, the decoction process is terminated. like or or The basic simmering time is extended according to the preset time. After each extension cycle, the time is rechecked until the simmering termination condition is met or the maximum allowable extension time is reached. In this invention, the preset time is 10 minutes and the maximum allowable extension time is 30 minutes.

[0041] in, express The density of the decoction is monitored in real time during the decoction process. Indicates the reference density threshold of the drug solution. express The pH value of the decoction should be monitored in real time during the decoction process. This indicates the lower limit of the normal pH range for the decocted medicinal liquid. This indicates the upper limit of the normal pH range for the decocted medicinal liquid.

[0042] After the first decoction is completed, the liquid outlet valve is opened to discharge the decoction into a temporary storage tank. A second decoction is then performed following the same process. The maximum and minimum allowable liquid levels and the basic decoction time for the second decoction can be set to different values ​​as needed, but the control logic is exactly the same as for the first decoction. The preferred maximum allowable liquid level for the second decoction is 80% of the effective volume of the tank, the minimum allowable liquid level is 80% of the minimum allowable liquid level for the first decoction, and the preferred basic decoction time is 40 minutes.

[0043] After the second decoction is completed, the decoctions from the two decoctions are combined and discharged into the first filtration unit for filtration. After filtration, the decoctions are fed into the first concentration unit.

[0044] The main body of the first concentration unit is a vacuum concentration tank, which is equipped with a jacketed heating device, a vacuum pump, a condenser, a stirring mechanism, a liquid receiver, and related pipelines and valves. The vacuum concentration tank is also equipped with sensors such as a first concentrate density sensor, a vacuum sensor, a first concentrate temperature sensor, and a first concentrate level sensor, as well as actuators such as an automatic vacuum adjustment device, an automatic temperature adjustment device, an outlet regulating valve, and an inlet regulating valve.

[0045] The central controller has a built-in controller for the first concentration unit, which presets the first concentrate relative density threshold, the first allowable density fluctuation range, the first concentrate maximum allowable temperature, the first concentrate target temperature, and the first target vacuum degree; the preset sampling period is 200-500ms. The first concentrate density sensor is installed on the circulation pipeline at the bottom of the tank, using an online vibration density meter. The concentrate is drawn out by the circulation pump, flows through the density meter, and then returns to the tank, forming a bypass online detection loop to collect the real-time density of the first concentrate. The vacuum degree sensor is installed in the gas phase space at the top of the tank to collect the absolute pressure inside the tank. The first concentrate temperature sensor is installed in the immersion zone in the middle of the tank to collect the real-time temperature of the first concentrate. The first concentrate level sensor is installed on the side wall of the tank to collect the real-time level of the first concentrate.

[0046] The real-time density of the first concentrate changes with the temperature of the concentrate. The real-time density of the first concentrate is converted to the real-time relative density of the first concentrate at 50℃. The controller of the first concentration unit has a built-in temperature compensation algorithm. in, Indicates 50℃ Real-time relative density of the first concentrate. express Real-time density of the first concentrate. This represents the volumetric expansion coefficient of the first concentrate, determined experimentally. express Real-time temperature of the first concentrate.

[0047] During the concentration process, set the highest priority safety interlock: Based on the preset maximum allowable temperature of the first concentrate, a temperature safety interlock is implemented. When the real-time temperature of the first concentrate exceeds the maximum allowable temperature, the heating output power is forcibly reduced. This invention limits the heating power to 50% of the maximum allowable temperature for concentration heating, and prohibits overheating regardless of whether the relative density of the concentrate meets the standard.

[0048] Based on the first target vacuum level of the vacuum concentrator, determine the upper and lower limits of the allowable pressure of the vacuum concentrator, and adjust the automatic vacuum adjustment device. When the real-time pressure of the concentrate exceeds the upper and lower limits of the allowable pressure of the concentrator, send a limiting command to the automatic vacuum adjustment device to limit the opening of the vacuum regulating valve to within ±5% of the current opening, and trigger an audible and visual alarm at the same time. If the pressure continues to exceed the upper and lower limits of the allowable pressure for more than 30 seconds, the safety shutdown procedure will be automatically executed.

[0049] During the concentration process, a closed-loop coordinated density regulation is implemented. Heating power and vacuum level are adjusted based on the real-time density and relative density threshold of the first concentrate. Specifically: After feeding is completed, the vacuum pump is started and the heating steam is turned on to enter the rapid evaporation stage. During this stage, the system operates at the maximum evaporation rate, with temperature control as the primary method and density monitoring as a secondary method.

[0050] Pre-set the allowable fluctuation range of the relative density threshold of the first concentrate. ,in, To allow for fluctuation amplitude, this invention uses a value of 0.02. The relative density threshold of the first concentrate is 1.10 (measured at 50°C).

[0051] When the real-time density of the first concentrate reaches the lower limit of the allowable fluctuation range of the relative density threshold of the first concentrate. Then, the process transitions to a deceleration and concentration phase. At this point, the heating power and vacuum level are reduced according to a preset gradient to slow down the evaporation rate and prevent over-concentration. The real-time density of the first concentrate is sampled every preset time interval (preferably 1-2 minutes), and the rate of change of the real-time density of the first concentrate is calculated after multiple consecutive samplings.

[0052] When the real-time density of the first concentrate falls into When the real-time density change rate of the first concentrate calculated from three consecutive samples is less than the preset density change rate threshold of the first concentrate, the concentration endpoint is determined to have been reached. The preferred density change rate threshold of the first concentrate is 0.001 g / cm³. 3·min.

[0053] Once the concentration endpoint is reached, discharge control is initiated, sequentially executing the following steps: closing the inlet valve, closing the steam valve, closing the vacuum regulating valve, breaking the vacuum, confirming that the tank temperature has dropped to the safe discharge temperature, and opening the discharge regulating valve to discharge the material. If the temperature does not drop to the safe discharge temperature within the preset time, an alarm is triggered, and the discharge valve is forcibly kept closed.

[0054] In this invention, the amount of water replenishment is precisely controlled in zones during the decoction process through interval judgment logic. Different water replenishment strategies are implemented in different liquid level zones. Combined with dynamic adjustment of the upper limit of heating power, the liquid level is quickly adjusted to the target value while effectively preventing the risks of boiling over and dry burning, thus improving the safety and stability of the decoction process. Simultaneously, the concept of effective decoction time is introduced, abandoning the traditional clock timing method. Time is accumulated only when both the decoction temperature and liquid level conditions are met. Combined with a dual-parameter endpoint verification mechanism of density and pH value, the interference of the heating stage on the extraction effect is overcome, ensuring the full dissolution of effective components and significantly improving the consistency of decoction effects between batches. The first concentration unit uses real-time feedback from an online density sensor as the termination criterion, accurately concentrating the first concentrate to a preset relative density threshold range. This avoids over-concentration or under-concentration caused by differences in human experience in traditional concentration, improving the accuracy and repeatability of the concentration process.

[0055] S2: Weigh the second Chinese herbal medicine composition according to the prescription ratio and crush it into coarse powder. Put the coarse powder into the percolation extraction unit and obtain the second monitoring data in real time during the percolation extraction process. Based on the second monitoring data, dynamically adjust the soaking time and percolation speed to obtain the initial percolate and the subsequent percolate. The subsequent percolate is sent to the second concentration unit and concentrated under reduced pressure to obtain the second concentrate.

[0056] It should be noted that in this invention, the ingredients of the second traditional Chinese medicine composition—Angelica sinensis, processed Polygonum multiflorum, Salvia miltiorrhiza, Carthamus tinctorius, Ligustrum lucidum, Epimedium brevicornu, Eucommia ulmoides, Tribulus terrestris, Angelica dahurica, and Eclipta prostrata—are weighed according to the prescription ratio and pulverized into coarse powder. The powder is then extracted using a percolation extraction process. The percolation extraction process includes a percolation extraction unit and a second concentration unit. The percolation extraction unit includes: a percolation tank with a jacketed insulation device, a solvent storage tank, a percolate collection tank, a flow control loop, and related pipelines and valves. Sensors installed in the tank and pipelines include: a percolate temperature sensor, a percolate pressure sensor, a percolate density sensor, and a flow sensor; the actuators include: a percolation speed regulating device and a solvent feed regulating valve. A percolator temperature sensor is installed in the immersion zone in the middle of the percolator tank to collect the real-time temperature of the percolator; a percolator pressure sensor is installed at the top and bottom of the percolator tank to collect the real-time differential pressure of the packing layer; a percolator density sensor is installed in the percolator outlet pipe to collect the real-time density of the percolator; a flow sensor is installed in the percolator outlet pipe to collect the real-time flow rate of the percolator; a percolator speed regulating device is installed in the percolator outlet pipe; and a solvent feed regulating valve is installed in the inlet pipe at the top of the percolator tank.

[0057] The impregnation step in the percolation process is a crucial stage for the dissolution of active ingredients. The impregnation temperature directly affects the dissolution rate and diffusion coefficient of active ingredients in the medicinal material. The lower the temperature, the slower the molecular motion, and the lower the dissolution rate of active ingredients, requiring a longer impregnation time to achieve the same dissolution effect. Conversely, the higher the temperature, the faster the dissolution rate. If impregnation continues for the original time, it may lead to over-impregnation, component damage, or energy waste. Therefore, the impregnation time can be appropriately shortened.

[0058] For each immersion liquid temperature sampling cycle, this invention introduces a temperature-compensated immersion time adjustment strategy. Using the baseline immersion time within the standard immersion temperature range as a benchmark, the baseline immersion time for each immersion liquid temperature sampling cycle is compensated according to a pre-calibrated piecewise linear compensation model. exist At that time, the real-time temperature of the leachate was higher than the standard impregnation temperature range, but had not reached the degradation criticality, so the impregnation time was shortened. in, Indicates the sampling period of the impregnation solution temperature. The corresponding shortening of the soaking time, This represents the high-temperature compensation coefficient, calibrated experimentally. It indicates the percentage reduction in immersion time required for every 1°C increase in the real-time leachate temperature over one immersion solution temperature sampling cycle. This indicates the maximum value within the standard immersion temperature range. This indicates the upper limit of the safe immersion temperature. Indicates the sampling period of the impregnation solution temperature. The real-time temperature of the impregnation solution, Indicates the sampling period of the impregnation solution temperature. The corresponding temperature deviation, This indicates the temperature sampling period.

[0059] exist At that time, the real-time temperature of the leachate is within a reasonable range, and the sampling period for the temperature of this impregnation solution does not generate a compensation duration.

[0060] exist If the real-time temperature of the leachate is below the standard range, the soaking time needs to be extended. in, Indicates the sampling period of the impregnation solution temperature. The corresponding extended immersion time, This represents the minimum value within the standard immersion temperature range. This represents the low-temperature compensation coefficient, calibrated experimentally. It indicates the percentage increase in immersion time required for each consecutive sampling cycle when the real-time temperature of the leachate drops by 1°C. Indicates the sampling period of the impregnation solution temperature. The deviation at the corresponding temperature.

[0061] In each sampling period, calculate the temperature-compensated immersion time for the current sampling period: Starting from the first immersion liquid temperature sampling cycle, after each immersion liquid temperature sampling cycle, the basic immersion time is dynamically compensated to obtain the temperature-compensated immersion time. Based on the temperature-compensated immersion time and the immersion time already accumulated, the remaining dynamic immersion time is calculated to determine the immersion completion time.

[0062] It should be noted that when the real-time temperature of the impregnation solution exceeds the upper limit of the safe impregnation temperature, the heating power should be reduced immediately and the cooling device should be activated to bring the real-time temperature of the impregnation solution back to the standard impregnation temperature range.

[0063] Furthermore, after impregnation is completed, the impregnation endpoint is determined by combining the real-time density of the impregnation liquid collected by the percolation liquid density sensor. If the real-time density of the impregnation liquid is greater than or equal to the preset impregnation liquid reference density, the impregnation is determined to be completed and percolation is automatically started; if the real-time density of the impregnation liquid is less than the preset impregnation liquid reference density, the impregnation time is automatically extended until the real-time density of the impregnation liquid reaches the standard or the maximum allowable impregnation time is reached.

[0064] It should be noted that the percolation extraction unit is set with a maximum allowable soaking time and a minimum allowable soaking time. The final soaking time must not exceed the maximum allowable soaking time and must not be less than the minimum allowable soaking time.

[0065] Percolation rate is a key parameter affecting extraction efficiency. If the rate is too fast, the active ingredients do not have enough time to diffuse fully, resulting in a low concentration of the percolated extract; if the rate is too slow, it affects equipment utilization and yield. Traditional percolation processes rely on manual adjustment of the bottom valve to control the flow rate, which is difficult to control precisely and results in large batch-to-batch variations.

[0066] This invention adjusts the percolation rate based on the real-time pressure difference of the packing layer. The pressure difference of the packing layer reflects the resistance of the medicinal material bed: a small real-time pressure difference indicates that the bed is loose and the resistance to the percolation liquid is small; an increase in the real-time pressure difference of the packing layer indicates that the bed is gradually compacted, the pores are blocked, and the viscous components are increasing; an excessively high pressure difference of the packing layer indicates that continued high-speed percolation is likely to lead to flow deviation, blockage, and abnormal equipment stress.

[0067] Therefore, the present invention presets a safe pressure differential range for the packing layer. If the real-time differential pressure of the packing layer deviates from the safe differential pressure range of the packing layer, not only is the differential pressure of the packing layer adjusted, but the percolation rate is also adaptively adjusted. Specifically: exist When the resistance of the packing layer is low, the first linear curve is used to increase the percolation rate. in, express Adjust the post-percolation rate frequently. Indicates the base percolation rate, This represents the pre-calibrated first percolation rate adjustment coefficient. This represents the minimum value of the safe differential pressure range of the packing layer. This indicates the real-time pressure difference of the packing layer.

[0068] The first linear curve satisfies the following constraints: in, This indicates the maximum permissible percolation rate. In a preferred embodiment, the maximum permissible percolation rate is 3 ml / min.

[0069] exist At the same time, maintain the baseline percolation flow rate.

[0070] exist If the resistance of the packing layer is too high, the second linear curve should be used to reduce the percolation rate. in, This represents the pre-calibrated second percolation rate adjustment coefficient. This indicates the maximum value of the safe differential pressure range for the packing layer.

[0071] The constraints for the second linear curve are: in, This indicates the maximum permissible percolation rate. In a preferred embodiment, the minimum permissible percolation rate is 1 ml / min.

[0072] According to the process requirements, 540ml of the initial filtrate is collected and stored separately, and 720ml of the subsequent filtrate is collected and sent to the second concentration unit.

[0073] In a preferred embodiment of the invention, the second concentration unit employs a scraped-film evaporator. The material enters from the top of the scraped-film evaporator, is distributed by a rotating distributor, and forms a uniform thin liquid film along the heated wall surface under centrifugal force. The scraper continuously rotates and scrapes the wall surface, constantly renewing the liquid film and pushing the material downwards. The heat from the heated wall surface causes the solvent in the liquid film to evaporate rapidly, secondary vapor is discharged from the top, and the concentrated liquid flows out from the bottom. The residence time of the material in the evaporator is extremely short, only 5-10 seconds, making it particularly suitable for concentrating heat-sensitive Chinese herbal medicine components.

[0074] The central controller incorporates a second concentration unit controller, used to control the heating power, automatic feeding and discharging, and vacuum level of the scraped-film evaporator. It presets the relative density threshold, allowable density fluctuation range, target temperature, and target vacuum level of the second concentrate. The second concentration unit includes the following online detection devices: a second concentrate density sensor, a second concentrate temperature sensor, a second concentrate vacuum level sensor, and a second concentrate level sensor.

[0075] The second concentrate density sensor is installed on the concentrate discharge pipeline, located after the discharge pump and before the discharge valve. The second concentration unit controller has a built-in temperature compensation algorithm to convert the real-time density of the second concentrate into the real-time relative density of the second concentrate at 50°C.

[0076] When the second concentrate level sensor detects that the real-time liquid level of the second concentrate in the evaporator is within the normal range, the automatic feeding system continuously feeds at a preset feeding rate. When the real-time liquid level of the second concentrate in the evaporator reaches the set upper limit, the feeding valve is closed and feeding is stopped. When the liquid level in the evaporator is lower than the set lower limit, the feeding valve is automatically opened to replenish the liquid.

[0077] If the second concentrate density sensor detects that the relative density of the second concentrate is greater than or equal to a preset relative density threshold, and the relative density of the second concentrate is not lower than the second concentrate relative density threshold after a preset number of consecutive samplings, and the relative density change rate of the second concentrate is less than a preset second concentrate change rate threshold, then the discharge regulating valve is controlled to discharge the concentrate. The preferred relative density threshold for the second concentrate is 1.02 (measured at 50℃), and the preferred density change rate threshold for the second concentrate is 0.001 g / cm³. 3 ·min.

[0078] For the temperature control of the thin-film evaporator, the real-time temperature of the second concentrate detected by the second concentrate temperature sensor is used as the feedback signal. The opening of the steam regulating valve is controlled by the PID algorithm to adjust the heating power so that the real-time temperature of the second concentrate is within the allowable fluctuation range of the target temperature of the second concentrate.

[0079] For vacuum control of the thin-film evaporator, the real-time vacuum level inside the tank detected by the second concentrate vacuum sensor is used as the feedback signal. The opening of the vacuum regulating valve is controlled by a PID algorithm to keep the pressure of the thin-film evaporator within the allowable fluctuation range of the second target vacuum level.

[0080] In a preferred embodiment of the invention, a temperature compensation strategy is employed in the percolation stage to dynamically adjust the soaking time, extending it at low temperatures and shortening it at high temperatures, overcoming the drawbacks of fixed-time soaking being affected by seasonal temperature fluctuations. Simultaneously, the percolation rate is adjusted using the pressure difference of the packing layer as a feedback closed loop to prevent clogging and ensure extraction efficiency, significantly improving the robustness and batch-to-batch consistency of the percolation process. In the second concentration stage, online density detection triggers automatic discharge in real time, eliminating the lag of manual sampling, avoiding over-concentration or under-concentration, and ensuring stable concentrate quality.

[0081] S3: Add the first concentrate and the second concentrate to the initial filtrate in sequence to obtain the initial mixed solution. Adjust the alcohol content of the initial mixed solution to the preset target alcohol content to obtain the mixed solution.

[0082] It should be noted that, due to batch-to-batch fluctuations in the residual ethanol content of the primary extract and the second concentrate, the first and second concentrates are added sequentially to the primary extract and stirred thoroughly to obtain the initial mixed solution. After the initial mixed solution stabilizes, its real-time density and real-time alcohol concentration are measured to obtain the real-time density of the initial mixed solution. Real-time alcohol concentration of the initial mixed solution .

[0083] To ensure that the final density of the mixed solution still meets quality standards after adjusting the alcohol content by adding 60% liquor or purified water, a target density for the initial mixed solution is pre-set. ,in The target density of the mixed drug solution was determined experimentally, and was preferably 1.05 (measured at 50°C). As a safety margin for density, the value is taken as 0.01–0.03 g / cm³. 3 calibrated through preliminary experiments. If... First, the initial mixed solution is concentrated under reduced pressure to increase its real-time density to [a certain value]. After concentration, the density and alcohol concentration are re-measured before proceeding to the alcohol content adjustment step.

[0084] Adjustment of alcohol content includes the following: Based on the target alcohol content, the amount of 60% baijiu to be added is calculated using the material balance equations. The calculation formula is as follows: in, This indicates the volume (mL) of 60% baijiu added. This indicates the current volume (mL) of the mixed drug solution. This indicates the current alcohol concentration (%). This indicates the target alcohol concentration, preferably 35%.

[0085] The amount of purified water to be added is then calculated using the material balance equations. The calculation formula is as follows: in, This indicates the volume (mL) of purified water added.

[0086] Then there is no need to add 60% liquor or purified water; simply bring the volume to the target level.

[0087] After the addition is complete, stir thoroughly and recheck the density and alcohol concentration of the mixed solution. If the deviation between the measured density and the target density of the mixed solution is within the allowable deviation range, and the deviation between the measured alcohol concentration and the target alcohol content is within the allowable deviation range, the mixture is deemed qualified and a mixed solution is obtained. If it exceeds the range, repeat the above steps of vacuum concentration, calculation, and alcohol content adjustment for fine-tuning until it is qualified.

[0088] In a preferred embodiment of the present invention, by measuring the density and alcohol concentration of the initial mixed medicinal solution in real time and combining it with a density safety margin design, it is ensured that the density of the final product still meets the requirements after the alcohol content is adjusted; and by using material balance to accurately calculate the amount to be added, combined with a closed-loop mechanism for concentration pretreatment and post-addition verification, the deviation in alcohol content of the final product caused by batch fluctuations in residual alcohol in the concentrate is effectively eliminated, significantly improving the quality consistency between batches of kidney-tonifying and hair-growth medicinal wine.

[0089] S4: The mixed medicine solution is delivered to the aging unit, and the third monitoring data during the aging process is acquired in real time. Based on the third monitoring data, the aging completion time is determined.

[0090] It should be noted that the mixed medicinal solution is transported to an empty aging tank in the aging unit, the inlet and outlet valves are closed, and the static aging process is started. The aging unit consists of multiple aging tanks connected in parallel, each tank is equipped with an independent online monitoring device, and they do not interfere with each other, supporting batch parallel aging.

[0091] The online detection hardware for each tank includes a sediment image recognition system and an online turbidity analyzer. The sediment image recognition system is equipped with a high-definition industrial CCD camera and a near-infrared backlight. The near-infrared backlight (wavelength 850–940 nm) is positioned outside a quartz sight glass window on one side of the aging tank, while the industrial CCD camera is positioned outside a sight glass window on the opposite side. The kidney-tonifying and hair-growth medicinal wine is brownish-red in color due to its pigment components (such as flavonoids in Astragalus membranaceus and polysaccharide-pigment complexes in Rehmannia glutinosa). These components have strong absorption in the visible light region (400–700 nm), causing the medicinal liquid to appear brownish-red, making it difficult for visible light to penetrate. However, in the near-infrared region (850–940 nm), the absorption of pigment components is significantly reduced, and the transmittance of the main body of the medicinal liquid to near-infrared light is significantly increased. However, the precipitates and flocs in the mixed medicinal solution are solid particles such as fragments of medicinal materials and macromolecular aggregates. Their scattering and blocking effect on near-infrared light is much stronger than that of the medicinal solution components in the dissolved state. Therefore, under the illumination of a near-infrared backlight, the intensity of transmitted light in the area where the precipitates and flocs are located is significantly lower than that in the surrounding medicinal solution area, and they appear as dark areas in the grayscale image, thus achieving effective differentiation between the precipitates and flocs and the background of the medicinal solution.

[0092] The distance and angle between the camera and the light source are pre-calibrated to ensure that the imaging field of view covers the entire cross-section of the tank. An online turbidity detector is installed in the clear liquid zone at the top of the tank to collect the turbidity of the supernatant.

[0093] Preprocessing of the cross-sectional image of the drug solution: median filtering to reduce noise and eliminate bubbles and light noise; histogram equalization to enhance the contrast between flocculants, precipitates and the drug solution background; ROI partitioning to divide the preprocessed image into upper, middle and lower layers according to height ratio.

[0094] The preprocessed image data is fed into a trained image recognition model. This model employs a hybrid architecture combining convolutional neural networks and traditional image processing, including a feature extraction network, a feature fusion network, and a segmentation and recognition network. The feature extraction network uses an 18-layer ResNet-18 residual network as its backbone to extract deep features from the image. The feature fusion network uses a Feature Pyramid Network (FPN) to achieve multi-scale feature fusion. The segmentation and recognition network uses the Otsu algorithm to perform adaptive threshold binarization on the bottom layer image, separating sediment from the background and detecting flocculants to identify suspended flocculant particles. The final outputs are the sediment percentage and flocculant dispersion density. The sediment percentage is the ratio between the total area of ​​sediment pixels in the bottom layer and the total area of ​​the effective drug solution area in the image. The flocculant dispersion density is the average number of flocculant pixels per unit area, representing the amount of suspended flocculants.

[0095] For training the image recognition model, cross-sectional images of aging tanks at different aging stages were collected. Professional technicians manually labeled each image with the location and contour of sediment areas and flocculent particles to construct the training dataset. A transfer learning strategy was adopted, using ResNet-18 weights pre-trained on ImageNet as initial parameters, and fine-tuning was performed on the training dataset.

[0096] Furthermore, based on the distribution characteristics of sediment and the turbidity of the supernatant collected by the online turbidity analyzer, three sets of steady-state judgment logic were designed, specifically as follows: Criterion 1: Steady-state conditions of sediment Condition ①: The proportion of sediment is greater than the preset sediment proportion threshold, preferably 20%; Condition ②: Within a continuously preset time period, the absolute value of the rate of change of the proportion of sediment is greater than the preset first rate of change threshold, which is preferably 0.5% / h.

[0097] If both conditions are met simultaneously, the first separation signal is generated, indicating that the sediment layer no longer thickens significantly and the sedimentation process has basically stabilized.

[0098] Judgment 2: Steady-state conditions of suspended flocs Condition ①: The dispersion density of the flocs is less than the preset dispersion density threshold, preferably 50 flocs / cm³. 2 ; Condition ②: Within a continuously preset time period, the absolute value of the rate of change of the flocculant dispersion density is not greater than the preset second rate of change threshold, which is preferably 1% / h.

[0099] If both conditions are met simultaneously, a second separation signal is generated, indicating that there are no longer a large number of particles continuing to settle downwards, and the suspension system has reached stability.

[0100] Judgment 3: Steady-state conditions for supernatant clarification Condition ①: The turbidity of the supernatant collected by the online turbidity detector is less than the preset turbidity threshold, preferably 5 NTU; Condition ②: Within a continuously preset time period, the absolute value of the rate of change of turbidity of the supernatant is not greater than the preset third rate of change threshold, which is preferably 0.3% / h.

[0101] If both conditions are met simultaneously, a third separation signal is generated, indicating that the clarity of the supernatant no longer continues to improve and the clarity is stable.

[0102] The central controller detects that at least two of the first separation signal, the second separation signal, and the third separation signal are in an effective holding state, that is, the signal has been triggered and has not been cleared, and this state is maintained continuously for no less than a preset confirmation time, such as 1 minute. Then it determines that the aging is complete and records the current time point as the aging completion time.

[0103] During steady-state timing, if the corresponding parameter fails to meet the threshold condition and fails to meet it for three consecutive samples, the corresponding timer is immediately reset to zero and the cumulative timing restarts. If the condition is not met for only one or two samples but is subsequently met, the timer continues to accumulate, preventing the timer from being frequently reset due to measurement noise or random fluctuations.

[0104] If the aging time exceeds the preset maximum aging time and the aging is still not determined to be complete, the system will automatically trigger forced discharge and issue an early warning to prevent production from being interrupted.

[0105] In this invention, aging is determined to be complete when any two of the three independent separation signals are generated. This mechanism has the following three advantages: First, redundancy protection effectively prevents misjudgment caused by single sensor failure or interference; second, timing fault tolerance allows for differences in the stabilization time of different characteristic parameters; and third, batch adaptation can adapt to the normal fluctuations in the characteristics of different batches of medicinal materials, thereby improving the robustness of the process.

[0106] S5: After aging, the mixed medicinal liquid is filtered and packaged to obtain the finished target medicinal wine.

[0107] It should be noted that after the aging unit determines that aging is complete, it receives an aging completion signal, and the corresponding aging tank starts automatic discharge, opens the upper supernatant discharge valve, and starts the conveying pump; the bottom drain valve remains closed. The online turbidity of the discharge pipeline is monitored in real time. If the turbidity suddenly and rapidly increases, it is determined that bottom sediment has been drawn in, and the conveying pump frequency is automatically reduced. In severe cases, discharge is suspended and an alarm is triggered. The remaining tanks that have not completed aging continue their original monitoring process and are unaffected.

[0108] Furthermore, after passing through multiple continuous filtration units, sediment and fine flocculent particles are removed, and the filtrate enters a buffer storage tank.

[0109] Furthermore, when the buffer storage tank reaches the minimum starting level, the bottling production line automatically starts. Empty bottles undergo bottle handling, rinsing, and hot air drying in sequence, and qualified empty bottles enter the filling station. The filling machine performs quantitative filling according to the preset single-bottle filling amount. A plunger metering pump is used to control the filling error. After filling, the bottles are automatically transported to the capping and crimping station to complete the sealing and obtain the finished medicinal wine.

[0110] Once the supernatant in the corresponding aging tank has been extracted, close the discharge valve. Start the online cleaning program for the pipelines and filters to rinse away the trapped sediment. Collect and treat the cleaning wastewater separately, and wait for the next batch to be fed after cleaning is complete.

[0111] Finally, the finished medicinal wine is tested, and the content of astragalus root extract (calculated as astragaloside A) per 1 ml must not be less than 0.014 mg. The astragaloside A content is determined by an automated high-performance liquid chromatograph, and the test data is automatically uploaded to an industrial Internet of Things platform for comparison with preset quality standards to determine the product's qualification.

[0112] This application deeply integrates traditional Chinese medicine wine preparation technology with intelligent control. Through online detection by multiple sensors and closed-loop control by a central controller, it realizes automated production of the entire process, including decoction, percolation, concentration, blending, and aging, which significantly reduces reliance on manual labor and batch-to-batch quality differences.
