Description

Technical Field

[0001] This invention relates to the field of low-temperature grinding technology, and more specifically, to a low-temperature grinding system and method for white pepper with adaptive temperature control. Background Technology

[0002] Low-temperature grinding technology for white pepper is a food processing technique that reduces the damage to pepper alkaloids and volatile flavor compounds caused by heat generated during grinding by controlling the grinding environment within a low-temperature range. It offers advantages such as maximizing the preservation of the spicy flavor of white pepper, preventing thermal degradation of active ingredients, and enhancing the sensory and nutritional quality of the finished product. It is widely used in high-end condiments and deep food processing.

[0003] In the low-temperature grinding process of white pepper, the flavor retention and particle uniformity of the finished product are core factors determining its value. However, in traditional low-temperature grinding processes, it is difficult to guarantee consistent grinding quality. Insufficient precision in controlling process parameters (such as grinding speed and chamber temperature control) leads to significant particle size differences between different batches and even within the same batch of white pepper. Some materials experience excessive volatilization of flavor substances due to localized temperature loss, severely affecting the overall quality of the finished product. It is also difficult to resolve the problem of uneven flavor retention caused by temperature fluctuations within the grinding chamber, resulting in unstable processing quality of localized materials and further reducing the uniformity of the finished product. Furthermore, the lack of a real-time data feedback mechanism during processing makes it impossible to promptly obtain information on particle size changes, flavor substance volatilization, and chamber temperature differences during grinding, hindering dynamic adjustment of process parameters and continuously impacting grinding quality and stability.

[0004] Therefore, it is necessary to design an adaptive temperature-controlled low-temperature grinding system and method for white pepper to solve the problems of inconsistent finished product quality, poor particle uniformity, and lack of real-time feedback control in traditional low-temperature grinding technology for white pepper. Summary of the Invention

[0005] In view of this, the present invention proposes an adaptive temperature-controlled low-temperature grinding system and method for white pepper, which aims to solve the problems of inconsistent finished product quality, poor particle uniformity, and lack of real-time feedback control in traditional low-temperature grinding technology for white pepper.

[0006] In one aspect, the present invention proposes an adaptive temperature-controlled low-temperature grinding system for white pepper, comprising: The data acquisition module is used to collect the initial parameters of the white pepper to be ground, including material moisture, initial particle size and grinding environment reference temperature, generate the initial data set of the material, and perform noise reduction processing on the data; An electrostatic pretreatment module, which is electrically connected to the data acquisition module, is used to eliminate static electricity from white pepper after initial screening based on the humidity parameters in the initial data set of the material. The low-temperature grinding module is used to receive white peppers after electrostatic pretreatment and send them into the low-temperature grinding chamber. The grinding operation is carried out according to the initially set grinding speed and initial temperature range. Real-time data on particle size, temperature fluctuation in the chamber and volatilization of flavor substances in the material are collected simultaneously during the grinding process. The temperature control analysis module is electrically connected to the low-temperature grinding module. The temperature control analysis module is used to perform coupled analysis on the data during the grinding process of the low-temperature grinding module, determine the allowable range of temperature deviation based on the critical value of white pepper flavor substance retention, generate a temperature adjustment coefficient by comparing the real-time temperature with the deviation range, and correct the temperature adjustment coefficient by combining the particle size change rate. An adaptive execution module is electrically connected to the low-temperature grinding module and the temperature control analysis module, respectively. The adaptive execution module is used to obtain the corrected temperature adjustment coefficient, dynamically adjust the temperature of the grinding chamber through the refrigeration unit to keep the temperature stable within the allowable deviation range, and adjust the grinding speed according to the real-time particle size data to complete the low-temperature grinding operation of white pepper.

[0007] Furthermore, the electrostatic pretreatment module includes: An ion wind generating unit is configured on the conveying path at the front end of the low-temperature grinding module. The ion wind generating unit is used to control the ion wind generating component to generate ion wind of corresponding intensity to eliminate static electricity on the surface of white pepper. An electrostatic monitoring unit is arranged adjacent to the ion wind generating component. The electrostatic monitoring unit is used to detect the charge density on the surface of the white pepper in real time and determine whether to activate the ion wind generating component based on the current charge density of the white pepper.

[0008] Furthermore, when the data acquisition module performs noise reduction processing on the data, it includes: The data acquisition module is also used to calculate the acquisition fluctuation values ​​of each parameter before the white pepper enters the pretreatment process; The data acquisition module is also configured to set a preset fluctuation threshold. When the collected fluctuation value is less than or equal to the preset fluctuation threshold, the data acquisition module determines that the original data is valid and directly includes it into the initial data set of the material. When the collected fluctuation value is greater than the preset fluctuation threshold, the data acquisition module determines that there is noise in the original data, performs smoothing processing on the original data, and incorporates the processed data into the initial data set of the material.

[0009] Furthermore, after completing the data noise reduction process, the data acquisition module is also configured to determine the initial operating parameters of the cryogenic grinding module based on the noise-reduced initial material dataset, including: The data acquisition module is also configured to extract the material humidity value and initial particle size value from the initial data set of the material after noise reduction, and preset a first humidity threshold, a second humidity threshold, a first particle size threshold, and a second particle size threshold. The data acquisition module is also configured to determine the initial temperature range and initial grinding speed of the low-temperature grinding module based on the relationship between the material's moisture content and the moisture threshold, and the relationship between the initial particle size and the particle size threshold. When the material humidity value is less than or equal to the first humidity threshold and the initial particle size value is less than or equal to the first particle size threshold, the data acquisition module determines the initial temperature range as the first initial temperature range and the initial grinding speed as the first speed. When the material humidity value is greater than the first humidity threshold and less than or equal to the second humidity threshold, and the initial particle size value is greater than the first particle size threshold and less than or equal to the second particle size threshold, the data acquisition module determines the initial temperature range as the second initial temperature range and the initial grinding speed as the second speed. When the material humidity value is greater than the second humidity threshold and the initial particle size value is greater than the second particle size threshold, the data acquisition module determines the initial temperature range as the third initial temperature range and the initial grinding speed as the third speed. When the material moisture content is less than or equal to the first moisture content threshold, and the particle size is greater than the first particle size threshold and less than or equal to the second particle size threshold, the initial temperature range is the first initial temperature range, and the initial grinding speed is the second speed. When the material moisture content is greater than the first moisture content threshold and less than or equal to the second moisture content threshold, and the particle size is less than or equal to the first particle size threshold, the initial temperature range is the second initial temperature range, and the initial grinding speed is the first speed. When the material moisture content is greater than the second moisture content threshold and the particle size is less than or equal to the second particle size threshold, the initial temperature range is the third initial temperature range and the initial grinding speed is the second speed. Among them, the first initial temperature range is greater than the second initial temperature range, which is greater than the third initial temperature range, and the first rotational speed is less than the second rotational speed, which is less than the third rotational speed.

[0010] Furthermore, when the electrostatic pretreatment module performs electrostatic elimination based on material moisture parameters, it includes: The electrostatic monitoring unit of the electrostatic pretreatment module is also configured to preset a first charge density threshold and a second charge density threshold, and to collect the charge density value of the white pepper surface in real time and compare it with the threshold. When the charge density value is less than or equal to the first charge density threshold, the electrostatic monitoring unit determines that the static electricity on the surface of the white pepper has been eliminated and sends a material conveying instruction to the low-temperature grinding module to send the white pepper that has been eliminated into the low-temperature grinding chamber. When the charge density value is greater than the second charge density threshold, the ion wind generating component of the electrostatic pretreatment module controls the ion wind generating unit to output the first intensity ion wind. After a preset first duration, the electrostatic monitoring unit re-collects the charge density value until the charge density value is less than or equal to the first charge density threshold. When the charge density value is greater than the second charge density threshold and less than or equal to the first charge density threshold, the ion wind generating component controls the ion wind generating unit to output the second intensity ion wind. After a preset second duration, the electrostatic monitoring unit re-collects the charge density value until the charge density value is less than or equal to the first charge density threshold. Among them, the first charge density threshold is greater than the second charge density threshold, the first intensity ion wind is greater than the second intensity ion wind, and the first duration is less than the second duration.

[0011] Furthermore, when the low-temperature grinding module receives the electrostatically neutralized white pepper and starts the grinding operation according to the initial operating parameters, it is also configured to monitor the grinding process data in real time and make preliminary judgments, including: The low-temperature grinding module is also configured to collect real-time particle size data, real-time temperature data inside the chamber, and real-time flavor substance volatilization data during the grinding process through a particle size sensor, a temperature sensor, and a flavor substance sensor, respectively, and to preset the target particle size range, temperature safety threshold, and upper limit value of flavor substance volatilization. The low-temperature grinding module is also configured to compare real-time particle size data with the target particle size range, real-time temperature data with the temperature safety threshold, and real-time flavor substance volatilization data with the upper limit of volatilization. When the real-time temperature data exceeds the temperature safety threshold or the real-time flavor substance volatilization data exceeds the upper limit of volatilization, the low-temperature grinding module immediately sends a data abnormality signal to the temperature control analysis module and suspends the grinding operation. When the real-time temperature data is less than or equal to the temperature safety threshold and the real-time flavor substance volatilization data is less than or equal to the upper limit of volatilization, but the real-time particle size data does not fall within the target particle size range, the low-temperature grinding module continues to collect data and send it to the temperature control and analysis module to maintain the current grinding state. When the real-time particle size data falls within the target particle size range, the real-time temperature data is less than or equal to the temperature safety threshold, and the real-time flavor substance volatilization data is less than or equal to the upper limit of volatilization, the low-temperature grinding module sends a grinding compliance signal to the temperature control analysis module and waits for the next instruction.

[0012] Furthermore, when the temperature control analysis module performs coupled analysis on the grinding process data and corrects the temperature adjustment coefficient, it includes: The temperature control analysis module is also configured to receive real-time data sent by the low-temperature grinding module and extract real-time temperature fluctuation values ​​and real-time particle size change rates. The temperature control analysis module is also configured to determine the allowable temperature deviation range based on the critical value for the retention of white pepper flavor substances, compare the real-time temperature fluctuation value with the allowable temperature deviation range, and generate an initial temperature adjustment coefficient. When the real-time temperature fluctuation value is less than or equal to half of the allowable temperature deviation range, the initial temperature adjustment coefficient is the first adjustment coefficient; When the real-time temperature fluctuation value is greater than half of the allowable temperature deviation range but less than or equal to the allowable temperature deviation range, the initial temperature adjustment coefficient is the second adjustment coefficient. When the real-time temperature fluctuation exceeds the allowable temperature deviation range, the initial temperature adjustment coefficient is the third adjustment coefficient. The temperature control analysis module is also configured to correct the initial temperature adjustment coefficient based on the real-time particle size change rate. When the real-time particle size change rate is greater than the preset change rate threshold, the initial temperature adjustment coefficient is corrected to the third adjustment coefficient, the fourth adjustment coefficient, and the fifth adjustment coefficient, wherein the third adjustment coefficient is 1.1 times the first adjustment coefficient, the fourth adjustment coefficient is 1.1 times the second adjustment coefficient, and the fifth adjustment coefficient is 1.1 times the third adjustment coefficient. When the real-time granularity change rate is less than or equal to the preset change rate threshold, the initial temperature adjustment coefficient is kept unchanged, and the corrected or unchanged temperature adjustment coefficient is used as the final temperature adjustment coefficient.

[0013] Furthermore, when the adaptive execution module adjusts the grinding chamber temperature and grinding speed according to the final temperature adjustment coefficient, it includes: The adaptive execution module is also configured to receive the final temperature adjustment coefficient sent by the temperature control analysis module, and control the refrigeration unit to adjust the grinding chamber temperature according to the coefficient: When the final temperature adjustment coefficient is the first adjustment coefficient, the refrigeration unit reduces the refrigeration power to the initial power that is times the first adjustment coefficient, so that the grinding chamber temperature approaches the midpoint of the initial temperature range. When the final temperature adjustment coefficient is the fourth adjustment coefficient, the refrigeration unit increases the refrigeration power to the initial power of the fourth adjustment coefficient, so that the grinding chamber temperature drops back to the initial temperature range. The adaptive execution module is also configured to synchronously receive real-time particle size data from the cryogenic grinding module, preset a particle size compliance deviation value, and when the absolute value of the difference between the real-time particle size data and the midpoint value of the target particle size range is less than the compliance deviation value, control the cryogenic grinding module to reduce the grinding speed to 0.8 times the initial speed. When the absolute value of the difference is greater than the target deviation value, maintain the current grinding speed; The adaptive execution module is also configured to collect the adjusted grinding chamber temperature in real time through a temperature sensor, and when the temperature stabilizes within the allowable temperature deviation range and the real-time particle size data falls into the target particle size range, it sends a grinding completion command to the low-temperature grinding module. If the adjusted temperature still exceeds the allowable temperature deviation range, the adaptive execution module resends a data request to the temperature control analysis module to obtain a new temperature adjustment coefficient and then adjusts again until the temperature reaches the target.

[0014] Furthermore, after the adaptive execution module completes the low-temperature grinding operation of white pepper, it also includes: The product detection and feedback module is electrically connected to the adaptive execution module. The product detection and feedback module is used to perform real-time particle size re-inspection and flavor substance content detection on the ground white pepper product, and generate a product detection report containing actual particle size distribution data and actual flavor substance retention.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The data acquisition module can accurately collect the initial parameters of the material and reduce noise. The low-temperature grinding module simultaneously collects real-time data on particle size, cavity temperature fluctuation and flavor substance volatilization during the grinding process, forming a full-chain data feedback of "initial data - process data", replacing the traditional processing mode without real-time data support, and realizing dynamic knowledge of the grinding status.

[0016] 2. The temperature control analysis module determines the temperature deviation range based on the critical value of flavor substance retention, and the adaptive execution module ensures that the temperature is stable within the allowable range, reducing flavor volatilization caused by local temperature runaway; the data acquisition module adjusts based on the initial parameters to avoid quality fluctuations caused by differences in initial materials, ensuring stable flavor retention and consistent quality.

[0017] 3. The electrostatic pretreatment module removes static electricity based on initial humidity, avoiding material agglomeration or uneven dispersion caused by static electricity, thus laying the foundation for uniform grinding; the adaptive execution module adjusts the rotation speed according to real-time particle size data, corrects the grinding intensity in real time, reduces particle size differences, and improves the uniformity of finished particles.

[0018] On the other hand, this application also provides an adaptive temperature-controlled low-temperature grinding method for white pepper, comprising the following steps: The initial parameters of the white pepper to be ground are collected, including material moisture, initial particle size and grinding environment reference temperature, to generate the initial data set of the material, and the data is denoised. Based on the humidity parameters in the initial data set of the material, static electricity is eliminated from the white pepper after initial screening; The system receives white pepper that has undergone electrostatic pretreatment and sends it into a low-temperature grinding chamber. The grinding operation is carried out according to the initially set grinding speed and initial temperature range. Real-time data on particle size, temperature fluctuations in the chamber, and volatilization of flavor substances in the material are collected simultaneously during the grinding process. The data during the grinding process are coupled and analyzed. The allowable temperature deviation range is determined based on the critical value of white pepper flavor substance retention. The temperature adjustment coefficient is generated by comparing the real-time temperature with the deviation range and then corrected by combining the particle size change rate. The corrected temperature regulation coefficient is obtained, and the temperature of the grinding chamber is dynamically adjusted to keep the temperature stable within the allowable deviation range. At the same time, the grinding speed is adjusted according to the real-time particle size data to complete the low-temperature grinding operation of white pepper.

[0019] It is understandable that the aforementioned adaptive temperature-controlled low-temperature grinding system and method for white pepper have the same beneficial effects, and will not be elaborated further here. Attached Figure Description

The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Reference Figure 1 In some embodiments of this application, an adaptive temperature-controlled low-temperature grinding system for white pepper includes: The data acquisition module is used to collect the initial parameters of the white pepper to be ground, including material moisture, initial particle size and grinding environment reference temperature, generate the initial data set of the material, and perform noise reduction processing on the data; The electrostatic pretreatment module is electrically connected to the data acquisition module. The electrostatic pretreatment module is used to eliminate static electricity in white pepper after initial screening based on the humidity parameters in the initial data set of the material. The low-temperature grinding module is used to receive white peppers after electrostatic pretreatment and send them into the low-temperature grinding chamber. The grinding operation is carried out according to the initially set grinding speed and initial temperature range. Real-time data on particle size, temperature fluctuation in the chamber and volatilization of flavor substances in the material are collected simultaneously during the grinding process. The temperature control and analysis module is electrically connected to the low-temperature grinding module. The temperature control and analysis module is used to perform coupled analysis on the data during the grinding process of the low-temperature grinding module. Based on the critical value of white pepper flavor substance retention, the allowable range of temperature deviation is determined. The temperature adjustment coefficient is generated by comparing the real-time temperature with the deviation range, and the temperature adjustment coefficient is corrected by combining the particle size change rate. The adaptive execution module is electrically connected to the low-temperature grinding module and the temperature control analysis module respectively. The adaptive execution module is used to obtain the corrected temperature adjustment coefficient, dynamically adjust the temperature of the grinding chamber through the refrigeration unit to keep the temperature stable within the allowable deviation range, and adjust the grinding speed according to the real-time particle size data to complete the low-temperature grinding operation of white pepper.

[0023] The data acquisition module in the above embodiments can accurately collect initial material parameters and reduce noise. The low-temperature grinding module simultaneously collects real-time data on particle size, cavity temperature fluctuations, and flavor substance volatilization during the grinding process, forming a full-chain data feedback of "initial data - process data," replacing the traditional processing mode without real-time data support and enabling dynamic awareness of the grinding status. The temperature control analysis module determines the temperature deviation range based on the critical value for flavor substance retention, and the adaptive execution module ensures that the temperature remains stable within the allowable range, reducing flavor volatilization caused by local temperature runaway. The data acquisition module adjusts based on initial parameters to avoid quality fluctuations caused by differences in initial materials, ensuring stable flavor retention and consistent quality. The electrostatic pretreatment module removes static electricity based on initial humidity, avoiding material agglomeration or uneven dispersion caused by static electricity, laying the foundation for uniform grinding. The adaptive execution module adjusts the rotation speed based on real-time particle size data, corrects the grinding intensity in real time, reduces particle size differences, and improves the uniformity of finished particles.

[0024] In a specific embodiment of this application, the above steps are implemented as follows: In a practical application scenario, the white pepper to be ground first has its material humidity, initial particle size, and grinding environment reference temperature collected by the data acquisition module, generating and noise-reducing an initial data set of the material; then, the data acquisition module transmits the humidity parameters in this data set to the electrostatic pretreatment module, which performs targeted electrostatic elimination operations on the white pepper after initial screening; the white pepper that has completed electrostatic pretreatment is sent to the low-temperature grinding module, which introduces it into the low-temperature grinding chamber and starts the grinding operation according to the initially set grinding speed and temperature range, while simultaneously collecting the actual data during the grinding process. The system collects real-time data on particle size, temperature fluctuations within the grinding chamber, and the volatilization of flavor compounds, and feeds this data back to the temperature control and analysis module. The module performs coupled analysis on the received real-time data, determines the allowable temperature deviation range based on the critical value for flavor compound retention in white pepper, compares the real-time temperature with this range to generate a temperature adjustment coefficient, and then corrects this coefficient based on the particle size change rate. Finally, the adaptive execution module acquires the corrected temperature adjustment coefficient from the temperature control and analysis module and the real-time particle size data from the low-temperature grinding module. It then dynamically adjusts the grinding chamber temperature through the refrigeration unit to stabilize it within the allowable deviation range, while simultaneously adjusting the grinding speed accordingly, ultimately completing the low-temperature grinding operation of white pepper.

[0025] The above scenarios are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0026] Specifically, the electrostatic pretreatment module includes: An ion wind generating unit is configured on the conveying path at the front end of the low-temperature grinding module. The ion wind generating unit is used to control the ion wind generating component to generate ion wind of corresponding intensity to eliminate static electricity on the surface of white pepper. The electrostatic monitoring unit is located adjacent to the ion wind generating component. The electrostatic monitoring unit is used to detect the charge density on the surface of the white pepper in real time and determine whether to activate the ion wind generating component based on the current charge density of the white pepper.

[0027] Specifically, the ion wind generating unit of the electrostatic pretreatment module is configured in the material conveying channel at the front end of the low-temperature grinding module, near the discharge port of the white pepper after primary screening. This unit has built-in voltage regulation and wind speed control components, and can receive material humidity parameters transmitted by the data acquisition module. When the humidity is low (the material is prone to strong static electricity), it automatically increases the output voltage and wind speed of the ion wind generating component to generate high-intensity ion wind to quickly neutralize the surface charge of the white pepper. When the humidity is high (the material has weak static electricity), it reduces the voltage and wind speed to avoid excessive blowing and material loss. The electrostatic monitoring unit is adjacent to the ion wind generating component and set in the downstream detection section of the conveying channel. It collects the surface charge density of the white pepper after ion wind treatment in real time through a contact charge sensor and compares the detection data with the preset "safe charge density threshold" in real time. If the detected charge density is higher than the threshold, it immediately triggers the ion wind generating component to start or increase its output. If the charge density is lower than the threshold, it sends a pause signal to the ion wind generating component, forming a closed-loop electrostatic elimination mechanism of "detection-regulation-re-detection" to ensure that the white pepper entering the low-temperature grinding module is always in a low static electricity state.

[0028] Understandably, in the electrostatic pretreatment module, the ion wind generating unit, being positioned on the front conveying path of the low-temperature grinding module, can generate ion winds of corresponding intensity to avoid material loss due to excessively strong ion winds or inability to remove static electricity due to excessively weak ion winds, thus achieving adaptive elimination of static electricity on the surface of white pepper. The electrostatic monitoring unit, located adjacent to the ion wind generating component, can detect the surface charge density of white pepper in real time and determine whether to activate the ion wind generating component, forming a "detection-control" closed loop. This prevents insufficient static electricity removal or excessive energy consumption. The synergy of the two can effectively solve the problems of material agglomeration and uneven dispersion caused by static electricity in traditional grinding, laying the foundation for uniform force and stable processing of materials during subsequent low-temperature grinding, further ensuring the uniformity of finished white pepper particles, and helping to improve the overall grinding quality.

[0029] Specifically, when the data acquisition module performs noise reduction processing on the data, it includes: The data acquisition module is also used to calculate the acquisition fluctuation values ​​of each parameter before the white pepper enters the pretreatment process; The data acquisition module is also configured to preset fluctuation thresholds; When the collected fluctuation value is less than or equal to the preset fluctuation threshold, the data acquisition module determines that the original data is valid and directly includes it into the initial data set of the material. When the collected fluctuation value is greater than the preset fluctuation threshold, the data acquisition module determines that there is noise in the raw data, performs smoothing processing on the raw data, and incorporates the processed data into the initial data set of the material.

[0030] Specifically, after the data acquisition module completes the data noise reduction process, it is also configured to determine the initial operating parameters of the cryogenic grinding module based on the noise-reduced initial material dataset, including: The data acquisition module is also configured to extract the material humidity value and initial particle size value from the initial data set of the material after noise reduction, and preset a first humidity threshold, a second humidity threshold, a first particle size threshold, and a second particle size threshold. The data acquisition module is also configured to determine the initial temperature range and initial grinding speed of the low-temperature grinding module based on the relationship between the material's moisture content and the moisture threshold, and the relationship between the initial particle size and the particle size threshold. When the material humidity value is less than or equal to the first humidity threshold and the initial particle size value is less than or equal to the first particle size threshold, the data acquisition module determines the initial temperature range as the first initial temperature range and the initial grinding speed as the first speed. When the material humidity value is greater than the first humidity threshold and less than or equal to the second humidity threshold, and the initial particle size value is greater than the first particle size threshold and less than or equal to the second particle size threshold, the data acquisition module determines the initial temperature range as the second initial temperature range and the initial grinding speed as the second speed. When the material humidity value is greater than the second humidity threshold and the initial particle size value is greater than the second particle size threshold, the data acquisition module determines the initial temperature range as the third initial temperature range and the initial grinding speed as the third speed. When the material moisture content is less than or equal to the first moisture content threshold, and the particle size is greater than the first particle size threshold and less than or equal to the second particle size threshold, the initial temperature range is the first initial temperature range, and the initial grinding speed is the second speed. When the material moisture content is greater than the first moisture content threshold and less than or equal to the second moisture content threshold, and the particle size is less than or equal to the first particle size threshold, the initial temperature range is the second initial temperature range, and the initial grinding speed is the first speed. When the material moisture content is greater than the second moisture content threshold and the particle size is less than or equal to the second particle size threshold, the initial temperature range is the third initial temperature range and the initial grinding speed is the second speed. Among them, the first initial temperature range is greater than the second initial temperature range, which is greater than the third initial temperature range, and the first rotational speed is less than the second rotational speed, which is less than the third rotational speed.

[0031] Specifically, the preset threshold for material humidity fluctuation is ±0.5%RH, the preset threshold for initial particle size fluctuation is ±0.1mm, and the preset threshold for grinding environment reference temperature fluctuation is ±0.3℃. When the single-time fluctuation of material humidity is ≤±0.5%RH, the initial particle size fluctuation is ≤±0.1mm, and the ambient temperature fluctuation is ≤±0.3℃, the original data is deemed valid and directly included in the dataset. If any parameter fluctuation exceeds the corresponding threshold (e.g., humidity fluctuation reaches ±0.8%RH), the original data is smoothed using the moving average method before being included in the dataset.

[0032] Specifically, the first humidity threshold is 10%RH, the second humidity threshold is 15%RH, the first particle size threshold is 3mm, and the second particle size threshold is 6mm; the initial temperature range and rotation speed correspond as follows: the first initial temperature range is 5-8℃, the first rotation speed is 1200-1500r / min, the second initial temperature range is 2-5℃, the second rotation speed is 1800-2200r / min, and the third initial temperature range is -2-2℃, the third rotation speed is 2500-3000r / min. For example, when the material moisture content is 8%RH (≤10%RH) and the initial particle size is 2mm (≤3mm), the initial temperature range is determined to be 5-8℃ and the rotation speed is 1200-1500r / min; when the material moisture content is 12%RH (10%-15%RH) and the initial particle size is 4mm (3-6mm), the initial temperature range is determined to be 2-5℃ and the rotation speed is 1800-2200r / min; when the material moisture content is 18%RH (>15%RH) and the initial particle size is 7mm (>6mm), the initial temperature range is determined to be -2 to 2℃ and the rotation speed is 2500-3000r / min. When the material moisture content is 9%RH (≤10%RH) and the initial particle size is 4mm (3-6mm), the initial temperature range is determined to be 5-8℃ and the rotation speed is 1800-2200r / min; when the material moisture content is 13%RH (10%-15%RH) and the initial particle size is 2mm (≤3mm), the initial temperature range is determined to be 2-5℃ and the rotation speed is 1200-1500r / min; when the material moisture content is 16%RH (>15%RH) and the initial particle size is 5mm (≤6mm), the initial temperature range is determined to be -2 to 2℃ and the rotation speed is 1800-2200r / min.

[0033] Understandably, the data acquisition module calculates the fluctuation values ​​of each parameter and compares them with preset fluctuation thresholds. It smooths out noisy data exceeding the thresholds and directly retains valid data. This accurately filters out interference information in the original data, ensuring the accuracy of the initial data set and preventing noisy data from causing deviations in subsequent parameter settings. Simultaneously, based on the noise-reduced data, it matches differentiated initial temperature ranges and grinding speeds according to multiple threshold combinations of material humidity and particle size. This breaks the limitations of fixed process parameters in traditional methods, allowing the low-temperature grinding module to accurately adapt to material characteristics from the start-up stage. This reduces problems such as excessive volatilization of flavor substances or uneven particle grinding caused by improper initial parameters. It provides a reliable data foundation for the coupled analysis of the temperature control analysis module and the dynamic regulation of the adaptive execution module, thereby effectively improving the quality stability, particle uniformity, and flavor retention of the finished white pepper product.

[0034] Specifically, when the electrostatic pretreatment module performs electrostatic elimination based on material moisture parameters, it includes: The electrostatic monitoring unit of the electrostatic pretreatment module is also configured to preset a first charge density threshold and a second charge density threshold, and to collect the charge density value of the white pepper surface in real time and compare it with the threshold. When the charge density value is less than or equal to the first charge density threshold, the electrostatic monitoring unit determines that the static electricity on the surface of the white pepper has been eliminated and sends a material conveying instruction to the low-temperature grinding module to send the white pepper that has been eliminated into the low-temperature grinding chamber. When the charge density value is greater than the second charge density threshold, the ion wind generating component of the electrostatic pretreatment module controls the ion wind generating unit to output the first intensity ion wind. After a preset first duration, the electrostatic monitoring unit re-collects the charge density value until the charge density value is less than or equal to the first charge density threshold. When the charge density value is greater than the second charge density threshold and less than or equal to the first charge density threshold, the ion wind generating component controls the ion wind generating unit to output the second intensity ion wind. After a preset second duration, the electrostatic monitoring unit re-collects the charge density value until the charge density value is less than or equal to the first charge density threshold. Among them, the first charge density threshold is greater than the second charge density threshold, the first intensity ion wind is greater than the second intensity ion wind, and the first duration is less than the second duration.

[0035] Specifically, the preset first charge density threshold of the electrostatic monitoring unit is 30 μC / m. 2 The second charge density threshold is 15 μC / m 2The ion wind intensity of the ion wind generating unit is measured by wind speed. The first intensity ion wind is set to 8-10 m / s, and the second intensity ion wind is set to 4-6 m / s. Regarding the preset duration, the first duration is set to 15-20 seconds, and the second duration is set to 30-35 seconds. In actual operation, when the surface charge density value of white pepper collected in real time by the electrostatic monitoring unit is ≤15 μC / m³, the ion wind intensity is optimal. 2 When the electrostatic discharge is deemed satisfactory, a delivery command is directly sent to the low-temperature grinding module; when the charge density value is >30μC / m 2 At that time, the ion wind generating unit outputs an initial intensity ion wind of 8-10 m / s, which lasts for 15-20 seconds. Then, the electrostatic monitoring unit re-detects the charge density until the value is ≤15 μC / m. 2 When the charge density is 15 μC / m 2 (excluding) -30μC / m 2 When the charge density is between (inclusive) and (inclusive), the ion wind generating unit outputs a second-intensity ion wind of 4-6 m / s, which lasts for 30-35 seconds. The electrostatic monitoring unit then detects the charge density again until it is ≤15 μC / m. 2 This ensures that the white peppercorns enter the subsequent grinding process in a low static electricity state.

[0036] Specifically, when the low-temperature grinding module receives the electrostatically neutralized white pepper and starts the grinding operation according to the initial operating parameters, it is also configured to monitor the grinding process data in real time and make preliminary judgments, including: The low-temperature grinding module is also configured to collect real-time particle size data, real-time temperature data inside the chamber, and real-time flavor substance volatilization data during the grinding process through particle size sensor, temperature sensor, and flavor substance sensor, respectively, and preset the target particle size range, temperature safety threshold, and upper limit value of flavor substance volatilization. The low-temperature grinding module is also configured to compare real-time particle size data with the target particle size range, real-time temperature data with the temperature safety threshold, and real-time flavor substance volatilization data with the upper limit of volatilization. When the real-time temperature data exceeds the temperature safety threshold or the real-time flavor substance volatilization data exceeds the upper limit of volatilization, the low-temperature grinding module immediately sends a data abnormality signal to the temperature control analysis module and suspends the grinding operation. When the real-time temperature data is less than or equal to the temperature safety threshold and the real-time flavor substance volatilization data is less than or equal to the upper limit of volatilization, but the real-time particle size data does not fall within the target particle size range, the low-temperature grinding module continues to collect data and send it to the temperature control and analysis module to maintain the current grinding state. When the real-time particle size data falls within the target particle size range, the real-time temperature data is less than or equal to the temperature safety threshold, and the real-time flavor substance volatilization data is less than or equal to the upper limit of volatilization, the low-temperature grinding module sends a grinding compliance signal to the temperature control analysis module and waits for the next instruction.

[0037] Specifically, the preset target particle size range is 60-100 mesh (corresponding to a particle diameter of approximately 0.15-0.25 mm), the temperature safety threshold is set at 10℃ (to avoid excessively high temperatures that could accelerate the volatilization of flavor substances), and the upper limit for the amount of flavor substances volatilized is set at 5% (based on the initial total amount of flavor substances in white pepper before grinding, the volatilization percentage shall not exceed this value). During actual grinding, the low-temperature grinding module collects and compares data in real time through sensors: when the real-time temperature inside the chamber is >10℃ (e.g., 12℃), or the real-time volatile content of flavor substances is >5% (e.g., 6.2%), it immediately sends a data abnormality signal to the temperature control analysis module and stops grinding; when the real-time temperature is ≤10℃ (e.g., 8℃) and the volatile content of flavor substances is ≤5% (e.g., 3.8%), but the real-time particle size is 45 mesh (approximately 0.35mm in diameter, not falling into the 60-100 mesh range) or 110 mesh (approximately 0.13mm in diameter, exceeding the range), it continues to collect data and send it to the temperature control analysis module and maintains the current grinding state; when the real-time particle size is 75 mesh (approximately 0.2mm in diameter, falling into the 60-100 mesh range), the real-time temperature is 6℃, and the volatile content of flavor substances is 2.5%, it sends a grinding compliance signal to the temperature control analysis module and waits for subsequent instructions.

[0038] Understandably, the electrostatic pretreatment module, by presetting different charge density thresholds, matches the output of ion winds of corresponding intensity and duration, forming a closed-loop electrostatic elimination mechanism of "detection-regulation-re-detection." This mechanism can accurately remove static electricity from the surface of white pepper to prevent material agglomeration during subsequent grinding, while also preventing material loss due to excessively strong ion winds or residual static electricity due to excessively weak ion winds. The low-temperature grinding module, by monitoring the particle size, chamber temperature, and flavor substance volatilization during the grinding process in real time, dynamically adjusts the grinding state according to preset thresholds and scenarios (pause when abnormal, maintain when particle size does not meet the standard, and send a signal when all standards are met). This can promptly avoid quality risks of overheating or excessive flavor volatilization, while ensuring that the particle size of the finished product meets the requirements. The synergistic effect of these two modules further enhances the controllability and stability of the white pepper grinding process, effectively ensuring the particle uniformity and flavor retention of the finished product, and reducing the generation of unqualified products due to static electricity or abnormal parameters.

[0039] Specifically, when the temperature control analysis module performs coupled analysis on the grinding process data and corrects the temperature regulation coefficient, it includes: The temperature control analysis module is also configured to receive real-time data sent by the low-temperature grinding module and extract real-time temperature fluctuation values ​​and real-time particle size change rates. The temperature control analysis module is also configured to determine the allowable temperature deviation range based on the critical value for the retention of white pepper flavor compounds, compare the real-time temperature fluctuation value with the allowable temperature deviation range, and generate an initial temperature adjustment coefficient. When the real-time temperature fluctuation value is less than or equal to half of the allowable temperature deviation range, the initial temperature adjustment coefficient is the first adjustment coefficient; When the real-time temperature fluctuation value is greater than half of the allowable temperature deviation range but less than or equal to the allowable temperature deviation range, the initial temperature adjustment coefficient is the second adjustment coefficient. When the real-time temperature fluctuation exceeds the allowable temperature deviation range, the initial temperature adjustment coefficient is the third adjustment coefficient. The temperature control analysis module is also configured to correct the initial temperature adjustment coefficient based on the real-time particle size change rate. When the real-time granularity change rate is greater than the preset change rate threshold, the initial temperature adjustment coefficient is corrected to the third adjustment coefficient, the fourth adjustment coefficient, and the fifth adjustment coefficient, wherein the third adjustment coefficient is 1.1 times the first adjustment coefficient, the fourth adjustment coefficient is 1.1 times the second adjustment coefficient, and the fifth adjustment coefficient is 1.1 times the third adjustment coefficient; When the real-time granularity change rate is less than or equal to the preset change rate threshold, the initial temperature adjustment coefficient is kept unchanged, and the corrected or unchanged temperature adjustment coefficient is used as the final temperature adjustment coefficient.

[0040] Specifically, considering the flavor preservation requirements of low-temperature grinding of white pepper and the temperature ranges of the initial low-temperature grinding module (-2-2℃, 2-5℃, 5-8℃), the allowable temperature deviation range is uniformly set to ±1℃; the preset particle size change rate threshold is 0.5 mesh / second (i.e., particle size change does not exceed 0.5 mesh per unit time); the initial temperature adjustment coefficient is set in a gradient: the first adjustment coefficient is 1.0 (corresponding to small fluctuations, fine adjustment is sufficient), the second adjustment coefficient is 1.05 (corresponding to moderate fluctuations, moderate adjustment is required), and the third adjustment coefficient is 1.1 (corresponding to fluctuations exceeding the range, requiring stronger adjustment). In actual coupled analysis, if the real-time temperature fluctuation value extracted by the temperature control analysis module is +0.4℃ (≤±0.5℃, i.e., half of the allowable temperature deviation range), the initial temperature adjustment coefficient is 1.0; if the fluctuation value is +0.8℃ (>±0.5℃ and ≤±1℃), the initial coefficient is 1.05; if the fluctuation value is +1.2℃ (>±1℃), the initial coefficient is 1.1.

[0041] Specifically, regarding coefficient correction: when the real-time particle size change rate is 0.6 mesh / second (>0.5 mesh / second), if the initial coefficient is 1.0, the corrected coefficient is 1.0×1.1=1.1 (i.e., the third adjustment coefficient); if the initial coefficient is 1.05, the corrected coefficient is 1.05×1.1=1.155 (i.e., the fourth adjustment coefficient); if the initial coefficient is 1.1, the corrected coefficient is 1.1×1.1=1.21 (i.e., the fifth adjustment coefficient); if the real-time particle size change rate is 0.4 mesh / second (≤0.5 mesh / second), the initial temperature adjustment coefficient remains unchanged, and the corrected or uncorrected coefficients are used as the final temperature adjustment coefficients and passed to the adaptive execution module for temperature control.

[0042] Understandably, the temperature control analysis module receives real-time data from the low-temperature grinding module, extracts temperature fluctuations and particle size change rates, and determines the temperature deviation range around the critical value for preserving white pepper flavor substances. This allows the generation of the initial temperature adjustment coefficient to accurately match the flavor protection requirements, avoiding flavor loss caused by single temperature control. At the same time, combined with the dynamic correction coefficient for particle size change rate—an amplification coefficient to enhance temperature control response when the change rate exceeds the threshold and a maintenance coefficient when it does not exceed the threshold—it achieves coupled control of "temperature-particle size." This avoids the risk of local overheating caused by excessive grinding intensity and prevents excessive temperature control from affecting particle size compliance. It effectively solves the problems of disconnect between temperature control and particle size adjustment and parameter fixation in traditional processes, providing a scientific basis for the precise temperature adjustment of the adaptive execution module. Ultimately, it ensures that the temperature during the grinding process remains stable within a reasonable range for flavor preservation, while simultaneously ensuring particle size uniformity and improving the overall quality of the finished product.

[0043] Specifically, when the adaptive execution module adjusts the grinding chamber temperature and grinding speed according to the final temperature adjustment coefficient, it includes: The adaptive execution module is also configured to receive the final temperature adjustment coefficient sent by the temperature control analysis module, and control the cooling unit to adjust the grinding chamber temperature according to the coefficient: When the final temperature adjustment coefficient is the first adjustment coefficient, the refrigeration unit reduces the refrigeration power to the initial power that is times the first adjustment coefficient, so that the grinding chamber temperature approaches the midpoint of the initial temperature range. When the final temperature adjustment coefficient is the fourth adjustment coefficient, the refrigeration unit increases the refrigeration power to the initial power of the fourth adjustment coefficient, so that the grinding chamber temperature drops back to the initial temperature range. The adaptive execution module is also configured to synchronously receive real-time particle size data from the cryogenic grinding module, preset a particle size compliance deviation value, and when the absolute value of the difference between the real-time particle size data and the midpoint value of the target particle size range is less than the compliance deviation value, control the cryogenic grinding module to reduce the grinding speed to 0.8 times the initial speed. When the absolute value of the difference is greater than the target deviation value, maintain the current grinding speed; The adaptive execution module is also configured to collect the adjusted grinding chamber temperature in real time through a temperature sensor. When the temperature stabilizes within the allowable temperature deviation range and the real-time particle size data falls within the target particle size range, it sends a grinding completion command to the low-temperature grinding module. If the adjusted temperature still exceeds the allowable temperature deviation range, the adaptive execution module resends a data request to the temperature control analysis module to obtain a new temperature adjustment coefficient and then adjusts again until the temperature reaches the target.

[0044] Specifically, the initial power of the cooling unit needs to be set to a reference value based on the initial temperature range of the low-temperature grinding module. For example, the initial cooling power for the first initial temperature range (5-8℃) is set to 1000W, the initial power for the second initial temperature range (2-5℃) is set to 1200W, and the initial power for the third initial temperature range (-2-2℃) is set to 1500W. When the final temperature adjustment coefficient received by the adaptive execution module is the first adjustment coefficient (1.0), if the current temperature is in the second initial temperature range (2-5℃), the cooling unit will adjust the power to 1200W×1.0=1200W. By maintaining the initial cooling intensity, the temperature of the grinding chamber will be guided closer to the midpoint of the range (3.5℃) to avoid excessive temperature fluctuations. If the final temperature adjustment coefficient is the fourth adjustment coefficient (1.155) and the current temperature is in the third initial temperature range (-2-2℃), the cooling power will be increased to 1500W×1.155=1732.5W. By enhancing the cooling effect, the temperature that may exceed the range (such as 3℃) will be quickly brought back to within -2-2℃.

[0045] Specifically, the preset parameters for particle size adjustment need to match the target particle size range. The midpoint of the target particle size range (60-100 mesh) is set to 80 mesh, and the particle size deviation is set to 5 mesh (i.e., when the absolute value of the difference is ≤ 5 mesh, it is considered close to meeting the standard). When the real-time particle size data received by the adaptive execution module is 82 mesh (the absolute value of the difference between 80 mesh and 2 ≤ 5), if the current initial rotation speed is 1800 r / min (the second rotation speed), the low-temperature grinding module is controlled to reduce the rotation speed to 1800 r / min × 0.8 = 1440 r / min to avoid over-grinding and resulting in overly fine particles. If the real-time particle size is 68 mesh (the absolute value of the difference between 80 mesh and 12 > 5), the current rotation speed of 1800 r / min is maintained to ensure grinding efficiency and to approach the target range as quickly as possible.

[0046] Specifically, the determination of temperature stability needs to be combined with the allowable temperature deviation range (±1℃). For example, if the current initial temperature range is 5-8℃, then the allowable temperature fluctuation range is 4-9℃. The adaptive execution module collects the temperature in real time through the temperature sensor. If the temperature is stable at 5-7℃ (within the 4-9℃ range) for 30 consecutive seconds, and the real-time particle size is 78 mesh (falling into the 60-100 mesh range), then the module immediately sends a grinding completion command to the low-temperature grinding module. If the temperature is still 9.5℃ after adjustment (outside the 4-9℃ range), the adaptive execution module immediately sends a new data request to the temperature control analysis module to obtain the updated temperature adjustment coefficient (such as the fifth adjustment coefficient of 1.21). Then, the cooling power is adjusted again according to the new coefficient (such as increasing it from 1000W to 1000W×1.21=1210W). The adjustment-detection process is repeated until the temperature stabilizes within the allowable range.

[0047] Understandably, the adaptive execution module dynamically adjusts the cooling power by receiving the final temperature regulation coefficient, ensuring that the grinding chamber temperature accurately approaches or falls back to the midpoint of the range, thus maintaining a stable temperature within the allowable deviation range for flavor retention. Simultaneously, it adjusts the rotation speed based on the real-time deviation between particle size and the target range to avoid over-grinding or under-grinding, ensuring uniform particle size. Furthermore, it forms a closed-loop control system of "adjustment-detection-re-adjustment" through real-time monitoring, effectively solving the problems of fixed process parameters, large temperature fluctuations, and uneven particle size in traditional processes. Ultimately, this improves the flavor retention, particle consistency, and processing stability of the finished white pepper product.

[0048] It is understandable that the operational logic of the second, third, and fifth adjustment coefficients is essentially an extension of the values ​​of the first and fourth adjustment coefficients.

[0049] Reference Figure 2 After the adaptive execution module completes the low-temperature grinding operation of white pepper, it also includes: The product detection and feedback module is electrically connected to the adaptive execution module. The product detection and feedback module is used to perform real-time particle size re-inspection and flavor substance content detection on the ground white pepper product, and generate a product detection report containing actual particle size distribution data and actual flavor substance retention.

[0050] Understandably, the product detection and feedback module performs real-time particle size re-inspection and flavor substance content detection on ground white pepper, generating a product detection report containing actual particle size distribution and flavor substance retention. This directly verifies whether the finished product particle size meets the standards and whether the flavor substance retention meets the requirements, thus preventing unqualified products from being released. It also provides real post-production data support for the subsequent data acquisition module to optimize the initial operating parameter settings and the temperature control analysis module to adjust the temperature adjustment coefficient. This fills the gap in the traditional grinding process, which lacks post-production quality verification and data review, and completes the "processing-detection-optimization" closed loop, continuously improving the finished product quality stability and process controllability of low-temperature ground white pepper.

[0051] Reference Figure 3 This application also provides an adaptive temperature-controlled low-temperature grinding method for white pepper, comprising the following steps: S100: Collects the initial parameters of the white pepper to be ground, including material moisture, initial particle size and grinding environment reference temperature, generates the initial data set of the material, and performs noise reduction processing on the data; S200: Based on the humidity parameters in the initial data set of the material, static electricity is eliminated from the white pepper after initial screening; S300: Receives white pepper after electrostatic pretreatment and sends it into the low-temperature grinding chamber. Grinding is carried out according to the initially set grinding speed and initial temperature range. Real-time data on particle size, temperature fluctuation in the chamber and volatilization of flavor substances in the material are collected simultaneously during the grinding process. S400: Performs coupled analysis on data during the grinding process, determines the allowable temperature deviation range based on the critical value of white pepper flavor substance retention, generates a temperature adjustment coefficient by comparing the real-time temperature with the deviation range, and corrects the temperature adjustment coefficient by combining the particle size change rate. S500: Obtains the corrected temperature regulation coefficient, dynamically adjusts the grinding chamber temperature to keep the temperature stable within the allowable deviation range, and adjusts the grinding speed according to real-time particle size data to complete the low-temperature grinding operation of white pepper.

The low-temperature grinding module is also configured to compare real-time particle size data with the target particle size range, real-time temperature data with the temperature safety threshold, and real-time flavor substance volatilization data with the upper limit of volatilization. When the real-time temperature data exceeds the temperature safety threshold or the real-time flavor substance volatilization data exceeds the upper limit of volatilization, the low-temperature grinding module immediately sends a data abnormality signal to the temperature control analysis module and suspends the grinding operation. When the real-time temperature data is less than or equal to the temperature safety threshold and the real-time flavor substance volatilization data is less than or equal to the upper limit of volatilization, but the real-time particle size data does not fall within the target particle size range, the low-temperature grinding module continues to collect data and send it to the temperature control and analysis module to maintain the current grinding state. When the real-time particle size data falls within the target particle size range, the real-time temperature data is less than or equal to the temperature safety threshold, and the real-time flavor substance volatilization data is less than or equal to the upper limit of volatilization, the low-temperature grinding module sends a grinding compliance signal to the temperature control analysis module and waits for the next instruction.

The temperature control analysis module is also configured to determine the allowable temperature deviation range based on the critical value for the retention of white pepper flavor substances, compare the real-time temperature fluctuation value with the allowable temperature deviation range, and generate an initial temperature adjustment coefficient. When the real-time temperature fluctuation value is less than or equal to half of the allowable temperature deviation range, the initial temperature adjustment coefficient is the first adjustment coefficient; When the real-time temperature fluctuation value is greater than half of the allowable temperature deviation range but less than or equal to the allowable temperature deviation range, the initial temperature adjustment coefficient is the second adjustment coefficient.

The temperature control analysis module is also configured to correct the initial temperature adjustment coefficient based on the real-time particle size change rate. When the real-time particle size change rate is greater than the preset change rate threshold, the initial temperature adjustment coefficient is corrected to the third adjustment coefficient, the fourth adjustment coefficient, and the fifth adjustment coefficient, wherein the third adjustment coefficient is 1.1 times the first adjustment coefficient, the fourth adjustment coefficient is 1.1 times the second adjustment coefficient, and the fifth adjustment coefficient is 1.1 times the third adjustment coefficient. When the real-time granularity change rate is less than or equal to the preset change rate threshold, the initial temperature adjustment coefficient is kept unchanged, and the corrected or unchanged temperature adjustment coefficient is used as the final temperature adjustment coefficient.

When the absolute value of the difference is greater than the target deviation value, maintain the current grinding speed; The adaptive execution module is also configured to collect the adjusted grinding chamber temperature in real time through a temperature sensor, and when the temperature stabilizes within the allowable temperature deviation range and the real-time particle size data falls into the target particle size range, it sends a grinding completion command to the low-temperature grinding module. If the adjusted temperature still exceeds the allowable temperature deviation range, the adaptive execution module resends a data request to the temperature control analysis module to obtain a new temperature adjustment coefficient and then adjusts again until the temperature reaches the target.

The grinding operation is carried out according to the initially set grinding speed and initial temperature range. Real-time data on particle size, temperature fluctuations in the chamber, and volatilization of flavor substances in the material are collected simultaneously during the grinding process. The data during the grinding process are coupled and analyzed. The allowable temperature deviation range is determined based on the critical value of white pepper flavor substance retention. The temperature adjustment coefficient is generated by comparing the real-time temperature with the deviation range and then corrected by combining the particle size change rate. The corrected temperature regulation coefficient is obtained, and the temperature of the grinding chamber is dynamically adjusted to keep the temperature stable within the allowable deviation range. At the same time, the grinding speed is adjusted according to the real-time particle size data to complete the low-temperature grinding operation of white pepper.
