Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine calcination technology, and in particular to a calcination machine for the production of traditional Chinese medicine by calcining in a pot. Background Technology

[0002] In the field of traditional Chinese medicine (TCM) processing, the inverted pot calcination method is an important processing technique, commonly used to prepare certain TCMs, such as carbonized human hair. Traditional calcination equipment uses a relatively simple heating method and lacks effective monitoring tools to understand the state of the calcination process in real time. It cannot accurately determine whether the calcination progress in different areas of the equipment is consistent. With the continuous development of the TCM industry, the quality requirements for TCM processing are becoming increasingly stringent, while also demanding higher production efficiency and lower energy consumption. Traditional calcination equipment can no longer meet these needs, urgently requiring a new type of calcination machine capable of precise temperature control, real-time monitoring of the calcination process, and automatic adjustment of heating intensity based on actual conditions, thereby improving the quality and efficiency of inverted pot calcination of TCM.

[0003] For example, Chinese Patent Publication No. CN116270232A discloses a calcination apparatus and method for processing Chinese medicinal herbs. This invention provides a calcination apparatus and method for processing Chinese medicinal herbs that can uniformly carbonize the herbs and improve the quality of calcination. The calcination apparatus for processing Chinese medicinal herbs includes a calcination rack, a heater, and a lower calcination pot. The heater is connected to the bottom wall of the calcination rack, and the lower calcination pot is connected to the middle of the lower part of the calcination rack. It also includes a vacuuming mechanism and a stirring mechanism. The vacuuming mechanism is located on the upper left side of the upper calcination pot, and the stirring mechanism is located on the upper right side of the upper calcination pot. This invention can accelerate the calcination speed and improve the calcination efficiency by extracting the gas between the upper and lower calcination pots through the vacuuming mechanism. Furthermore, the stirring rack can make the herbs heat evenly and achieve the effect of uniform carbonization.

[0004] The following problems still exist in the existing technology:

[0005] The existing technology does not take into account the uneven heating rate of the medicinal materials in different areas of the equipment due to the uneven residual heat and uneven distribution of the medicinal materials during the continuous calcination process. This leads to differences in the calcination process. The existing technology cannot judge the differences in the calcination process based on the highly representative smoke color characteristics during the production process, and cannot make targeted adjustments to the heating intensity, which affects the uniformity of the continuous calcination of medicinal materials. Summary of the Invention

[0006] Therefore, the present invention provides a calcining machine for the production of traditional Chinese medicine by calcining in a pot, which overcomes the problems in the prior art that it is impossible to judge the differences in the calcination process based on the highly representative smoke color characteristics during the production process, and that it is impossible to make targeted adjustments to the heating intensity.

[0007] To achieve the above objectives, the present invention provides a calcining machine for the production of traditional Chinese medicine by calcination in a pot, comprising:

[0008] The body includes a calcination chamber for holding Chinese medicinal materials for calcination and a chamber cover disposed on top of the calcination chamber for sealing the calcination chamber;

[0009] A temperature control assembly, located at the bottom of the machine body, includes a rotating shaft and a burner connected to the rotating shaft via symmetrical supports for heating the calcination chamber; the burner rotates with the rotating shaft.

[0010] Several monitoring components, including several monitoring pipeline loops arranged at preset intervals on the side of the calcination chamber and a smoke detector arranged on each monitoring pipeline loop to obtain the color intensity of smoke in each monitoring pipeline loop;

[0011] Both ends of each monitoring pipeline loop are connected to the calcination chamber, so that the smoke in the calcination chamber can pass through each monitoring pipeline loop;

[0012] A process analysis module, which is connected to several monitoring components, includes a region division unit and a smoke analysis unit. The region division unit is used to divide the calcination chamber into several calcination sub-regions according to the location of each monitoring pipeline loop.

[0013] The smoke analysis unit is used to determine whether there are differences in the forging process in each forging sub-region based on the fluctuation of smoke color intensity in each monitoring pipeline loop within a preset time, and to screen characteristic forging sub-regions.

[0014] A production control module, which is connected to the process analysis module and the temperature control component, is used to adjust the heating power of the burner for each characteristic forging sub-region based on the difference in smoke color intensity of each characteristic forging sub-region.

[0015] Furthermore, the area division unit is used to draw rays from the central axis of the calcination chamber at equal angular intervals to divide the internal area of ​​the calcination chamber into several calcination sub-regions. Each calcination sub-region corresponds to a unique monitoring component, and the central axis is perpendicular to the plane where the chamber cover is located.

[0016] Furthermore, the monitoring pipeline circuit also includes a switching valve installed at the connection point with the calcination chamber to control the flow of smoke at the connection point. A first switching valve is installed at the connection point that is far from the top of the calcination chamber, and a second switching valve is installed at the connection point that is close to the top of the calcination chamber.

[0017] Furthermore, in response to the forging start command, each monitoring pipeline loop controls the second switch valve to close and the first switch valve to open for a preset time to collect smoke from the monitoring pipeline loop within the preset time.

[0018] Furthermore, the smoke detector acquires the smoke color intensity in each monitoring pipeline loop, including the red light intensity, green light intensity, and blue light intensity of the smoke.

[0019] Furthermore, the smoke analysis unit is used to calculate the standard deviation of the red light intensity of smoke based on the red light intensity of smoke in each monitoring pipeline loop, calculate the standard deviation of the green light intensity of smoke based on the green light intensity of smoke in each monitoring pipeline loop, and calculate the standard deviation of the blue light intensity of smoke based on the blue light intensity of smoke in each monitoring pipeline loop.

[0020] Furthermore, the smoke analysis unit is used to calculate the smoke color intensity fluctuation value based on the standard deviation of the red light intensity of the smoke, the standard deviation of the green light intensity of the smoke, and the standard deviation of the blue light intensity of the smoke. The smoke color intensity fluctuation value is positively correlated with the standard deviation of the red light intensity of the smoke, the standard deviation of the green light intensity of the smoke, and the standard deviation of the blue light intensity of the smoke.

[0021] Furthermore, the smoke analysis unit is used to compare the smoke color intensity fluctuation value with a preset smoke color intensity fluctuation reference value;

[0022] If the smoke color intensity fluctuation value is greater than the smoke color intensity fluctuation reference value, the smoke analysis unit determines that there are differences in the forging process in each forging sub-region.

[0023] Furthermore, the smoke analysis unit is also used to calculate the intensity difference between the blue light intensity of the smoke and the comparison value of the blue light intensity of the smoke in each monitoring pipeline loop, and to screen the forging sub-regions where the absolute value of the intensity difference is greater than the absolute value of the intensity difference reference as characteristic forging sub-regions.

[0024] The contrast value of the blue light intensity of the smoke is determined based on the average value of the blue light intensity of the smoke in each monitoring pipeline loop.

[0025] Furthermore, the production control module is also used to adjust the heating force of the burner on each characteristic forging sub-region according to the intensity difference value, wherein the heating force is positively correlated with the intensity difference value.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention sets up a body, a temperature control component, several monitoring components, a process analysis module, and a production control module. The temperature control component heats the calcination chamber, the smoke detector acquires the color intensity of smoke in each monitoring pipeline loop, the area division unit divides the calcination chamber into several calcination sub-regions, the smoke analysis unit determines whether there are differences in the calcination process in each calcination sub-region and screens characteristic calcination sub-regions, and the production control module adjusts the heating power of the burner for each characteristic calcination sub-region. Thus, it realizes the judgment of differences in the calcination process based on the highly representative smoke color characteristics in the production process, and the targeted adjustment of the heating power, ensuring the uniformity of continuous calcination of medicinal materials and improving the quality and efficiency of traditional Chinese medicine calcination production.

[0027] In particular, the present invention divides the internal area of ​​the calcination chamber into several calcination sub-regions by dividing the area into several calcination sub-regions by regional division units. Those skilled in the art will understand that dividing the calcination sub-regions by extending rays from the central axis to the surrounding areas can cover the temperature distribution characteristics of different locations in the calcination chamber. Thus, it achieves a comprehensive division of the heated area of ​​the calcination chamber and improves the accuracy of monitoring the calcination progress of medicinal materials.

[0028] In particular, this invention controls the flow of smoke by monitoring the switching valves of the pipeline circuit at the conduction position. As those skilled in the art will understand, medicinal materials contain various organic substances and a large amount of water. Under the high temperature conditions of calcination, these components will decompose to form smoke. The color of the smoke generated during the production process of the calcining machine can characterize the progress of the calcination of traditional Chinese medicine. This invention collects the smoke generated in each calcination sub-region during the calcination process by monitoring the opening and closing of the switching valves of the pipeline circuit. Thus, it realizes the judgment of the difference in calcination process based on the highly characterizing smoke color characteristics during the production process, thereby improving the accuracy of calcination process monitoring.

[0029] In particular, this invention acquires the red, green, and blue light intensities of smoke within each monitoring pipeline circuit using a smoke detector. Those skilled in the art will understand that the three primary colors—red, green, and blue—have different wavelength ranges and characteristics, effectively distinguishing different colors. Comprehensive analysis of these three primary colors can reduce the impact of environmental interference on color detection. During the calcination of medicinal materials, the color of the smoke changes with the calcination process and the composition of the medicinal materials. Collecting data on the three primary colors (red, green, and blue) can accurately identify these color changes. This invention acquires the red, green, and blue light intensities of smoke within each monitoring pipeline circuit using a smoke detector, thereby enabling the judgment of differences in the calcination process based on the highly representative smoke color characteristics during production, improving the accuracy of calcination process monitoring.

[0030] In particular, the present invention uses a smoke analysis unit to determine whether there are differences in the calcination process in each calcination sub-region. Those skilled in the art will understand that the smoke color intensity fluctuation value can characterize the degree of heat distribution difference in different areas of the calcination chamber. The larger the smoke color intensity fluctuation value, the more obvious the heat difference between each calcination sub-region. The smaller the smoke color intensity fluctuation value, the more uniform the heat distribution in each calcination sub-region. Thus, the problem of uneven heating of medicinal materials can be detected in a timely manner, thereby improving the quality and efficiency of traditional Chinese medicine calcination production.

[0031] In particular, this invention adjusts the heating power of the burner for each characteristic calcination sub-region based on the intensity difference value through the production control module. Those skilled in the art will understand that during the calcination process, the greater the absolute value of the intensity difference between the blue light intensity of the smoke in the calcination sub-region and the contrast value of the blue light intensity of the smoke, the more abnormal the heating rate of the medicinal material in the calcination sub-region is, and the more necessary it is to adjust the calcination heating power in that region. Thus, it realizes the judgment of the calcination process difference based on the highly representative smoke color characteristics during the production process, and makes targeted adjustments to the heating power, thereby improving the uniformity of continuous calcination of medicinal materials.

Figure 2 This is a schematic diagram of the internal structure of a calcining machine used in the production of traditional Chinese medicine using a pot-cooking method, according to an embodiment of the present invention. Figure 3 This is a top view of the lid of an embodiment of the present invention. A calcining machine for the production of traditional Chinese medicine using a calcining pot according to the present invention includes:

[0042] The body includes a calcination chamber 1 for holding Chinese medicinal materials for calcination and a chamber cover 2 disposed on the top of the calcination chamber 1 for sealing the calcination chamber 1;

[0043] Specifically, the cover 2 is also provided with a waste gas outlet 21 for discharging the waste gas generated inside the calcining chamber 1 during the calcination process;

[0044] The temperature control component is located at the bottom of the machine body and includes a rotating shaft 3 and a burner 5 connected to the rotating shaft 3 via a symmetrical bracket 4 for heating the calcination chamber 1. The burner 5 rotates with the rotating shaft 3.

[0045] Several monitoring components, including several monitoring pipeline loops 6 arranged at preset intervals on the side of the calcination chamber 1, and a smoke detector 7 arranged on each monitoring pipeline loop 6 to obtain the color intensity of smoke in each monitoring pipeline loop 6.

[0046] Both ends of each monitoring pipeline loop 6 are connected to the calcination chamber 1 so that the smoke in the calcination chamber 1 can pass through each monitoring pipeline loop 6;

[0047] Specifically, the monitoring pipeline circuit 6 of the present invention is a transparent pipeline to facilitate the acquisition of the smoke color intensity within each monitoring pipeline circuit 6;

[0048] The process analysis module is connected to several monitoring components, including a region division unit and a smoke analysis unit. The region division unit is used to divide the calcination chamber 1 into several calcination sub-regions according to the location of each monitoring pipeline loop 6.

[0049] The smoke analysis unit is used to determine whether there are differences in the forging process in each forging sub-region based on the fluctuation of smoke color intensity in each monitoring pipeline loop 6 within a preset time, and to screen characteristic forging sub-regions.

[0050] The production control module, which is connected to the process analysis module and the temperature control component, is used to adjust the heating power of the burner 5 to each characteristic forging sub-region according to the difference in smoke color intensity of each characteristic forging sub-region.

[0051] Specifically, the present invention can drive the rotating shaft 3 to rotate by setting an electric motor, so that the rotating shaft 3 drives the burner 5 to rotate through the symmetrical support 4. This is a common technical means used by those skilled in the art, and will not be described in detail here.

[0052] Specifically, the present invention does not limit the specific structure of the burner 5. The combustion of the gas is achieved by means of electronic ignition or electric spark ignition, and the heating intensity is controlled by controlling the amount of gas supplied. This is the prior art and will not be described in detail here.

[0053] Specifically, the present invention does not limit the specific structure of the smoke detector 7. Preferably, it can be an RGB color sensor. The RGB color sensor can use photodiodes or photoresistors and other photosensitive elements to sense light of different wavelengths. These photosensitive elements convert the received light signals into electrical signals, and then process and calculate them through internal circuitry to obtain the light intensity values ​​of the three primary colors of red, green and blue. RGB color sensors are widely used in industrial automation production detection and environmental monitoring, which is existing technology and will not be described in detail here.

[0054] Specifically, the present invention does not limit the specific structure of the production control module, which can be constructed using logic components, such as field-programmable logic components, microprocessors, processors used in computers, etc., which will not be elaborated here.

[0055] Specifically, the area division unit is used to draw rays from the central axis of the calcination chamber 1 at equal angular intervals to divide the internal area of ​​the calcination chamber 1 into several calcination sub-regions. Each calcination sub-region corresponds to a unique monitoring component. The central axis is perpendicular to the plane where the chamber cover 2 is located.

[0056] Specifically, the present invention does not limit the specific structure of the region division unit. Preferably, it can be a processor that performs virtual region division on the pre-built internal structure model of the calcination chamber 1 according to a pre-stored software algorithm. This is prior art and will not be described in detail here.

[0057] Specifically, the present invention divides the internal area of ​​the calcination chamber 1 into several calcination sub-regions by dividing the area into several calcination sub-regions by regional division units. Those skilled in the art will understand that dividing the calcination sub-regions by extending rays from the central axis to the surrounding areas can cover the temperature distribution characteristics of different locations in the calcination chamber 1. Thus, it achieves a comprehensive division of the heated area of ​​the calcination chamber 1 and improves the accuracy of monitoring the calcination progress of medicinal materials.

[0058] For details, please continue reading Figure 1 The monitoring pipeline circuit 6 also includes a switch valve installed at the connection position with the calcination chamber 1 to control the flow of smoke at the connection position. A first switch valve 61 is installed at the connection position with a larger distance from the top of the calcination chamber 1, and a second switch valve 62 is installed at the connection position with a smaller distance from the top of the calcination chamber 1.

[0059] Specifically, each monitoring pipeline circuit 6 responds to the forging start command by controlling the second switching valve 62 to close and controlling the first switching valve 61 to open for a preset time to collect the smoke from the monitoring pipeline circuit 6 within the preset time.

[0060] It is understandable that different colors of smoke and exhaust gas will be generated during the calcination process of Chinese medicinal materials as the production process changes. The smoke and exhaust gas float from the bottom to the top of the calcination chamber 1. The present invention opens the first switch valve 61 to allow the smoke at the bottom of the calcination chamber 1 to enter the monitoring pipeline circuit 6. During this process, the second switch valve 62 is kept closed so that the smoke entering the monitoring pipeline circuit 6 remains in the monitoring pipeline circuit 6.

[0061] Specifically, this invention monitors the switching valve of the pipeline circuit 6 at the conduction position to control the flow of smoke. As those skilled in the art will understand, medicinal materials contain various organic substances and a large amount of water. Under the high temperature conditions of calcination, these components will decompose to form smoke. The color of the smoke generated during the production process of the calcining machine can characterize the progress of the calcination of traditional Chinese medicine. This invention monitors the opening and closing of the switching valve of the pipeline circuit 6 to collect the smoke generated in each calcination sub-region during the calcination process. Thus, it realizes the judgment of the difference in calcination process based on the highly characterizing smoke color characteristics during the production process, thereby improving the accuracy of calcination process monitoring.

[0062] Specifically, the smoke detector 7 acquires the smoke color intensity in each monitoring pipeline loop 6, including the red light intensity, green light intensity, and blue light intensity of the smoke.

[0063] Specifically, this invention uses a smoke detector 7 to acquire the red, green, and blue light intensities of smoke within each monitoring pipeline loop 6. Those skilled in the art will understand that the three primary colors—red, green, and blue—have different wavelength ranges and characteristics, effectively distinguishing different colors. Comprehensive analysis of these three primary colors can reduce the impact of environmental interference on color detection. During the calcination of medicinal materials, the color of the smoke changes with the calcination process and the composition of the medicinal materials. Collecting data on the three primary colors (red, green, and blue) can accurately identify these color changes. This invention uses a smoke detector 7 to acquire the red, green, and blue light intensities of smoke within each monitoring pipeline loop 6, thereby enabling the judgment of differences in the calcination process based on the highly representative smoke color characteristics during production, thus improving the accuracy of calcination process monitoring.

[0064] Specifically, the smoke analysis unit is used to calculate the standard deviation S of the red light intensity of the smoke based on the red light intensity of the smoke in each monitoring pipeline loop 6. R The standard deviation S of the green light intensity of the smoke is calculated based on the green light intensity of the smoke in each monitoring pipeline loop 6. G And the standard deviation S of the blue light intensity of the smoke is calculated based on the blue light intensity of the smoke in each monitoring pipeline loop 6. B .

[0065] Specifically, the smoke analysis unit is used to analyze the smoke based on the standard deviation S of the red light intensity. R The standard deviation S of the green light intensity of the smoke G and the standard deviation S of the blue light intensity of the smoke B Calculate the smoke color intensity fluctuation value W, and the smoke color intensity fluctuation value W is related to the standard deviation S of the red light intensity of the smoke. R The standard deviation S of the green light intensity of the smoke G and the standard deviation S of the blue light intensity of the smoke B They are positively correlated.

[0066] The smoke color intensity fluctuation value W can be calculated using the following formula:

[0067] W = μ × S R +β×S G +γ×S B ;

[0068] Wherein, μ is the weighting coefficient of red light intensity in smoke, β is the weighting coefficient of green light intensity in smoke, and γ is the weighting coefficient of blue light intensity in smoke. The weighting coefficients μ, β, and γ are selected by those skilled in the art based on the influence of historical data on the calculation results of red light intensity, green light intensity, and blue light intensity in smoke. μ + β + γ = 1. Preferably, the weighting coefficients μ, β, and γ can be set to 0.3, 0.3, and 0.4.

[0069] Specifically, please refer to Figure 4 As shown, it is a logic flowchart of the smoke analysis unit in an embodiment of the present invention for determining whether there are differences in the forging process in each forging sub-region. The smoke analysis unit is used to compare the smoke color intensity fluctuation value W with the preset smoke color intensity fluctuation reference value W0.

[0070] If the smoke color intensity fluctuation value W is less than or equal to the smoke color intensity fluctuation reference value W0, then the smoke analysis unit determines that there is no difference in the forging process in each forging sub-region;

[0071] If the smoke color intensity fluctuation value W is greater than the smoke color intensity fluctuation reference value W0, then the smoke analysis unit determines that there are differences in the forging process in each forging sub-region.

[0072] The value of the smoke color intensity fluctuation reference value W0 can be set according to the accuracy requirements of smoke color detection. The smaller the value of the smoke color intensity fluctuation reference value W0, the more accurately the subtle changes in smoke color intensity can be detected. Preferably, the range of the smoke color intensity fluctuation reference value W0 can be set to [25, 50].

[0073] Specifically, this invention uses a smoke analysis unit to determine whether there are differences in the calcination process in each calcination sub-region. Those skilled in the art will understand that the smoke color intensity fluctuation value can characterize the degree of heat distribution difference in different areas within the calcination chamber 1. The larger the smoke color intensity fluctuation value, the more obvious the heat difference between each calcination sub-region. The smaller the smoke color intensity fluctuation value, the more uniform the heat distribution in each calcination sub-region. Thus, the problem of uneven heating of medicinal materials can be detected in a timely manner, improving the quality and efficiency of traditional Chinese medicine calcination production.

[0074] Specifically, the smoke analysis unit is also used to calculate the blue light intensity L of the smoke within each monitoring pipeline loop 6. B Comparison value L with the blue light intensity of smoke B0 The intensity difference value L1, where L1 = L B -L B0The forging sub-region where the absolute value of the strength difference |L1| is greater than the absolute value of the strength difference reference |L1'| is selected as the characteristic forging sub-region;

[0075] Among them, the blue light intensity contrast value L of the smoke B0 The value L2 is determined based on the average value of the blue light intensity of the smoke within each monitoring pipeline loop 6.

[0076] The value of the absolute reference value of intensity difference |L1'| is calculated based on the average value L2 of the blue light intensity of the smoke in each monitoring pipeline loop 6. |L1'|=δ×L2, where δ is the value factor of the absolute reference value of intensity difference, and the value range of δ is [0.05, 0.2]. The smaller the value of the absolute reference value of intensity difference |L1'|, the more characteristic forging sub-regions are selected.

[0077] It is understandable that different colors of smoke and exhaust gases are generated during the calcination process of traditional Chinese medicine. In response to the start of calcination, as the temperature gradually rises, the moisture in the raw materials is evaporated first, producing a small amount of white water vapor smoke. As the temperature continues to rise, the decomposition of organic matter in the raw materials produces denser smoke. Compared to denser colored smoke, the white smoke has a higher RGB color intensity (L) of blue light in the smoke. B Significant changes will occur, so it can be determined based on the intensity L of the blue light in the smoke. B The numerical changes indicate the speed of calcination of Chinese medicinal materials; the RGB values ​​of smoke color, specifically the blue light intensity L in the smoke, are used to determine the speed of calcination. B The smaller the value, the faster the calcination of Chinese medicinal materials enters the organic matter decomposition stage.

[0078] Specifically, the production control module is also used to adjust the heating force of the burner 5 on each characteristic forging sub-region according to the intensity difference value L1, wherein the heating force is positively correlated with the intensity difference value L1.

[0079] Specifically, this invention adjusts the heating intensity of burner 5 for each characteristic calcining sub-region based on the intensity difference value through a production control module. Those skilled in the art will understand that during the calcination process, the larger the absolute value of the intensity difference between the blue light intensity of the smoke in the calcining sub-region and the contrast value of the blue light intensity of the smoke, the more abnormal the heating rate of the medicinal material in the calcining sub-region is, and the greater the need to adjust the calcination heating intensity of that region. When the intensity difference value is positive, the blue light intensity L in the RGB value of the smoke color... B The larger the value, the slower the progress of the calcination of Chinese medicinal materials into the organic matter decomposition stage, requiring increased heating intensity to ensure uniform calcination. When the intensity difference value is negative, the blue light intensity L in the RGB value of the smoke color is... BThe smaller the value, the faster the calcination of Chinese medicinal materials enters the organic matter decomposition stage, requiring a reduction in heating intensity to ensure the uniformity of calcination. This invention uses the intensity difference between the blue light intensity of the smoke and the blue light intensity of the smoke to identify abnormal calcination areas and adjust the heating intensity of the corresponding areas. Thus, it realizes the ability to judge the differences in calcination process based on the highly representative smoke color characteristics during production, and to make targeted adjustments to the heating intensity, thereby improving the uniformity of continuous calcination of medicinal materials.

[0080] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings.
