Description

Technical Field

[0001] The present invention relates to, in particular, a traditional Chinese medicine processing and toxicity-reducing device and method based on multi-wavelength laser dynamic regulation. Background Art

[0002] Traditional Chinese medicine processing is an important technique in traditional Chinese medicine. Its main purpose is to remove toxic components in medicinal materials through physical or chemical methods, enhance the medicinal effect, improve the physical and chemical properties of medicinal materials, and make them more suitable for clinical application.

[0003] The processing technology directly affects the safety, effectiveness, and stability of medicinal materials. Currently, commonly used traditional Chinese medicine processing methods include steaming, frying, sulfur fumigation, baking, etc. However, these methods have the following limitations: High-temperature destruction of active ingredients: Traditional methods (such as steaming and frying) require long-term high-temperature treatment, which easily leads to the degradation of heat-sensitive components (such as polysaccharides, volatile oils, flavonoids), reducing the medicinal effect. Chemical residue risk: Although sulfur fumigation can effectively remove toxins, it may introduce sulfur dioxide residues, affecting the safety of medicinal materials and even causing harm to human health. Inability to precisely reduce toxicity: The removal of toxins (such as aconitine and aristolochic acid) by traditional processes relies on empirical control and lacks quantitative means, easily resulting in incomplete removal of toxins or loss of active ingredients. Summary of the Invention

[0004] In order to overcome the above-mentioned drawbacks of the prior art, the purpose of the present invention is to provide a traditional Chinese medicine processing and toxicity-reducing device and method based on multi-wavelength laser dynamic regulation.

A fixed space for laying the medicinal materials flat is formed between the first grid structure and the second grid structure.

Detailed Embodiments

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0028] To solve the technical problems in the prior art, the present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0029] As Figures 1 to 3 shown, an embodiment of the present invention discloses a traditional Chinese medicine processing and toxicity-reducing device based on multi-wavelength laser dynamic regulation, including a closed box body 1, a laser array module, a vibration and flipping platform, an on-line monitoring device 7, and a control module 8.

[0030] Referring to Figure 1 , the laser array module includes a multi-wavelength composite laser 6 and a laser beam homogenizing and shaping head 5. The multi-wavelength composite laser 6 is connected to the control module 8. The multi-wavelength composite laser 6 supports output in the near-infrared, mid-infrared, and ultraviolet bands. The laser beam homogenizing and shaping head 5 is connected to the multi-wavelength composite laser 6. The laser beam homogenizing and shaping head 5 is usually arranged above the vibration and flipping platform to perform laser processing on the medicinal materials placed on the vibration and flipping platform.

[0031] The multi-wavelength composite laser 6 has a wide wavelength coverage range and integrates at least three types of lasers, such as semiconductor lasers and fiber lasers, which can cover the 800-1500nm near-infrared band, the 2-10μm mid-infrared band, and the 200-400nm ultraviolet band. The absorption spectra of toxins and active ingredients in different medicinal materials are significantly different. Multi-wavelength lasers are used to selectively decompose toxins and retain active ingredients.

[0032] Due to its advantages such as high precision, strong controllability, and concentrated energy, laser technology has been widely used in fields such as material processing and medical treatment. In traditional Chinese medicine processing, laser heating has the following advantages:

[0033] Selective heating: Different medicinal material components have selective absorption characteristics for specific wavelengths of laser, enabling targeted heating, precisely decomposing toxins without damaging active ingredients.

[0034] High efficiency and energy saving: Laser energy is concentrated on the target, and the energy consumption is significantly lower than that of traditional methods.

[0035] No chemical residues: Laser treatment does not require chemical reagents, avoiding the risk of chemical residues.

[0036] Real-time controllability: Combining spectral monitoring technology, laser parameters can be adjusted in real time to ensure the processing effect.

[0037] The vibration and flipping platform uses mechanical vibration and flipping devices to ensure that the medicinal materials are evenly heated during the laser treatment process, preventing the upper-layer medicinal materials from blocking the bottom-layer ones and avoiding inconsistent treatment effects.

[0038] In some embodiments, referring to Figure 1 , the vibration and flipping platform includes a vibration platform 4, a vibration driving member, and a transmission member. The upper end of the vibration platform 4 has a planar structure for supporting the medicinal materials. The vibration driving member and the transmission member are built into the vibration platform 4. The vibration driving member, as the power source of vibration, can be a motor. By the high-speed rotation of the motor, vibration force is generated. The transmission member is connected to the vibration driving member and contacts the bottom of the vibration platform 4. The vibration force of the vibration driving member is transmitted to the vibration platform 4 through the transmission member, causing the platform to generate high-frequency vibration, thereby driving the medicinal materials to continuously flip on the vibration platform 4.

[0039] Furthermore, multiple vibration driving members and transmission members are built into the vibration platform 4 and are evenly distributed at the bottom of the vibration platform 4 to ensure that the medicinal materials on the entire platform fully receive the acting forces of vibration and flipping, and to ensure uniform heating during the laser treatment process.

[0040] In some embodiments, referring to Figure 3 , the vibration and flipping platform further includes a first grid structure 41 and a second grid structure 42. The first grid structure 41 and the second grid structure 42 are stacked in sequence above the vibration platform 4. The first grid structure 41 and the second grid structure 42 are connected to each other to form an integral structure. A fixed space for laying the medicinal materials flat is formed between the first grid structure 41 and the second grid structure 42.

[0041] Moreover, this fixed space also functions to limit and fix the medicinal materials. During the overall flipping process of the first grid structure 41 and the second grid structure 42, it can effectively prevent the medicinal materials from piling up and gathering, ensuring uniform heating of the medicinal materials during the laser treatment process. The gravitational force of the medicinal materials will also make the grid belt 413 of the first grid structure 41 or the second grid structure 42 stick more closely to the vibration platform 4, so that the vibration force of the vibration platform 4 is transmitted to the medicinal materials.

[0042] Further, the first grid structure 41 and the second grid structure 42 are connected into an integral module by fixing members. The rotating mechanism 43 is connected to the fixing members. The rotating mechanism 43 drives the first grid structure 41 and the second grid structure 42 to rotate through the fixing members to achieve the flipping function, so as to flip the medicinal materials for laser irradiation treatment. At the same time, before and after the first grid structure 41 and the second grid structure 42 are flipped, the positions of the first grid structure 41 and the second grid structure 42 are exchanged up and down. The part of the first grid structure 41 or the second grid structure 42 that supports the medicinal materials, such as the grid belt 413, is laid flat on the vibration platform 4, and further with the help of the mechanical vibration built in the vibration platform 4, the medicinal materials are heated evenly during the laser treatment process. Among them, a lifting structure can be installed on the vibration platform 4 to drive the vibration platform 4 to rise and fall, so as to facilitate the smooth flipping of the first grid structure 41 and the second grid structure 42 as a whole.

[0043] Further, the first grid structure 41 or the second grid structure 42 adopts a winding structure design. When the first grid structure 41 or the second mesh structure adopts a winding design, before the medicinal materials are conveyed, it is necessary to adjust the first grid structure 41 or the second grid structure 42 with the winding design to the lower layer position, and the grid belt 413 contacts the vibration platform 4, so as to drive the medicinal materials to be laid flat evenly forward and avoid gathering at the feeding end of the vibration platform 4.

[0044] Further, before laser treatment of the medicinal materials, the first grid structure 41 or the second mesh structure located in the lower layer is longer than the second grid structure 42 or the first mesh structure located in the upper layer at the feeding end, which is convenient for smoothly receiving the medicinal materials conveyed by the front-end feeding equipment. For example, the first grid structure 41 is located in the lower layer and the second mesh structure is located in the upper layer. The feeding end of the first grid structure 41 is closer to the feeding equipment than the feeding end of the second mesh structure. During the laser treatment process, the positions of the first grid structure 41 and the second mesh structure may change once, twice or even multiple times. It is only necessary to adjust the longer first grid structure 41 or the second grid structure 42 to the lower layer position before laser treatment of the medicinal materials.

[0045] In some embodiments, both the first grid structure 41 and the second mesh structure adopt a winding structure design, and their structures are basically the same.

[0046] In a specific example, the first grid structure 41 is provided with a first roller 411, a second roller 412 and a grid belt 413. The first roller 411 is arranged at the front end of the vibration platform 4 close to the feeding port, the second roller 412 is arranged at the other end of the vibration platform 4 close to the discharging port, one end of the grid belt 413 is rotatably wound around the outer periphery of the first roller 411, and the other end of the grid belt 413 is rotatably wound around the outer periphery of the second roller 412.

[0047] When the first grid structure 41 is placed on the lower layer and the second grid structure 42 is located on the upper layer, the medicinal materials are conveyed and spread flat on the grid belt 413 of the first grid structure 41. The first roller 411 and the second roller 412 rotate to drive the medicinal materials to move towards the discharge port of the vibration platform 4, making the spreading of the medicinal materials more uniform. Among them, the grid belt 413 on the first roller 411 is released forward, and the grid belt 413 on the second roller 412 is rolled up forward. The rotation directions of the first roller 411 and the second roller 412 of the first grid structure 41 are the same. The first roller 411 and the second roller 412 of the second grid structure 42 can also rotate to assist the medicinal materials to spread forward faster and more evenly. The rotation directions of the grid belt 413 of the first grid structure 41 and the grid belt 413 of the second grid structure 42 are opposite. Further, their speeds can be inconsistent or the same.

[0048] After the medicinal materials are laser-treated, the first roller 411 and the second roller 412 rotate and move forward, causing the medicinal materials to fall onto the discharge conveyor belt 3-2.

[0049] The grid belt 413 has multiple grid holes, ensuring that the medicinal materials between the first grid structure 41 and the second grid structure 42 are evenly irradiated by the laser. Additionally, different grid belts 413 can be replaced according to different medicinal materials. An adjustment structure can also be added to adjust the distance between the grid belt 413 of the first grid structure 41 and the grid belt 413 of the second grid structure 42.

[0050] The laser beam homogenizing and shaping head 5 and the vibration and flipping platform are arranged inside the closed box body 1. Usually, the laser beam homogenizing and shaping head 5 is installed on the top of the closed box body 1.

[0051] The on-line monitoring device 7, integrated with GC-IMS (gas chromatography-ion mobility spectrometry) and Raman spectrometer, on-line and real-time monitors the change of the components of the medicinal materials, so as to adjust the laser parameters in real time, ensure that the treatment effect meets the standard, and avoid over-treatment or toxin residue.

[0052] The control module 8, with a medicinal material-wavelength database built-in, realizes dynamic matching and closed-loop regulation of laser parameters. Specifically, it matches the laser parameters according to the type of medicinal materials and different stages of medicinal material processing, and dynamically adjusts the laser power, wavelength and irradiation time according to the real-time spectral data, ensuring that the toxin residue in the medicinal materials is lower than the set value, such as the toxin residue ≤ 0.01%.

[0053] Among them, selective toxin decomposition: through a preset wavelength database (such as the best decomposition wavelength of aconitine is 980nm, and the protection wavelength of ginsenoside is 1450nm), the laser targets and excites the toxin molecular bond, uses the photothermal effect to locally decompose the toxin at high temperature, and at the same time avoids the destruction of the active ingredients.

[0054] Dynamic wavelength switching: Automatically switch the wavelength combination according to the type of medicinal material and the processing stage (such as the wavelength sequence for the three stages of "decomposition - drying - solidification"), achieving precise control of "one medicine, one strategy".

[0055] Real-time feedback closed-loop control: Integrate on-line gas monitoring of toxin residues, and the intelligent module dynamically adjusts the laser parameters to ensure that the processing effect meets the standards (such as the aconitine residue ≤ 0.01%).

[0056] See Figure 2 , and the specific control steps are as follows:

[0057] Initial parameter setting: First, set the initial processing parameters through the control module 8 (including the type of medicinal material, weight, and the required medicinal material processing method, such as selecting the "detoxification - solidification" mode for aconite).

[0058] Feeding of medicinal materials: After cleaning the raw medicinal materials, they are spread evenly on the feeding conveyor belt 3-1 through the feeding mechanism 2 and transported to the vibration flipping platform for laser irradiation treatment.

[0059] Laser detoxification treatment: For example, use 980nm laser to irradiate the surface of the medicinal material to decompose toxic components such as aconitine.

[0060] Vibration flipping operation: During the irradiation process, flip the medicinal material through the vibration function in the vibration flipping platform to ensure that the medicinal material is evenly heated during the laser treatment.

[0061] On-line monitoring and adjustment: The on-line monitoring device 7 uses an integrated component monitoring device (GC-IMS and Raman spectroscopy) to provide real-time feedback on the toxin content and water vapor content. If the standards are not met, the medicinal material is transported back to the vibration flipping platform through the transfer device, and the irradiation time is extended or the power is increased for continued detoxification treatment.

[0062] Drying and solidification treatment of medicinal materials: If the detoxification step has been completed, enter the drying and solidification stage, switch the laser wavelength to 1450nm for gentle drying, and solidify the effective polysaccharide components.

[0063] Post-treatment: After completing laser detoxification and drying and solidification, cool and collect the processed medicinal materials, and enter the medicinal material quality inspection and packaging module 13 to complete quality verification and packaging.

[0064] Selectively decompose the toxins in the medicinal material by multi-wavelength laser; dynamically switch the wavelength to complete drying and solidification of the effective components; ensure uniform heating of the medicinal material through the vibration flipping module; and achieve closed-loop optimization of the processing parameters based on spectral feedback.

[0065] In some embodiments, it further includes a feeding module, a conveying module, an air extraction and exhaust module, an exhaust gas treatment module 11, a transfer platform 12, and a medicinal material quality inspection and packaging module 13.

[0066] The blanking module is provided with an automatic blanking mechanism 2 to ensure that the medicinal materials can be laid flat on the feeding conveyor belt 3-1. The blanking mechanism 2 includes an inclined hopper and a material leveling pipeline. The end of the hopper is connected to the material leveling pipeline, and the diameter of the material leveling pipeline gradually decreases from the front end to the rear end. The rear end of the material leveling pipeline is located above the feeding conveyor belt 3-1.

[0067] The conveying module is provided with a conveyor belt with temperature control function, which supports the uniform laying and dynamic positioning of medicinal materials. It includes a feeding conveyor belt 3-1 and a discharging conveyor belt 3-2. The feeding conveyor belt 3-1 and the discharging conveyor belt 3-2 are located inside the closed box body 1. The discharging end of the discharging conveyor belt 3-2 extends outside the closed box body 1. The feeding conveyor belt 3-1 is located between the vibration and turning platform and the blanking mechanism 2, and the discharging conveyor belt 3-2 is located at the discharging end of the vibration and turning platform.

[0068] The air extraction and exhaust module includes an internal air extraction fan 9-1 and an exhaust fan 9-2, and a ventilation pipeline 10, which ensures that the toxic and harmful gases and moisture volatilized inside the box body can be discharged in time. The air extraction fan 9-1 and the exhaust fan 9-2 are located inside the closed box body 1, and the exhaust fan 9-2 is connected to the ventilation pipeline 10.

[0069] The waste gas treatment module 11 is connected to the exhaust pipeline of the air extraction and exhaust module to collect and treat the extracted harmful gases.

[0070] Processing traditional Chinese medicine with the equipment of the present invention has the following advantages:

[0071] Uniform heating: Through the vibration and turning platform, it is ensured that the medicinal materials are uniformly heated during the laser treatment process, avoiding the upper medicinal materials from blocking the bottom medicinal materials.

[0072] Precise detoxification: The toxin removal rate ≥ 90%, and the effective ingredient retention rate ≥ 95%.

[0073] High efficiency and energy saving: The laser energy is concentrated on the target point, and the energy consumption is reduced by 60% compared with the traditional steaming method.

[0074] Green and environmental protection: Avoid the use of chemical reagents, and there is no waste water and waste gas emission.

[0075] Standardized production: The intelligent database supports one-key calling of multi-herb parameters, improving the process consistency.

[0076] The present invention also discloses a method for reducing toxicity in traditional Chinese medicine processing based on multi-wavelength laser dynamic regulation. Using the above-mentioned equipment for reducing toxicity in traditional Chinese medicine processing based on multi-wavelength laser dynamic regulation, it includes the following steps:

[0077] Determine the herb information, which includes the herb type, weight, and processing mode;

[0078] Obtain the medicinal material - wavelength data according to the medicinal material information, match the processing stage of the medicinal material and the corresponding laser parameters for the processing stage to control the operation of the laser array module, where the laser parameters include the laser power, wavelength, and irradiation time corresponding to the medicinal material in different stages;

[0079] Set the speed, vibration time and intensity, number of flips and flip time for the medicinal material to be tiled on the vibration platform 4 according to the medicinal material information to control the vibration and flipping module.

[0080] Among them, the speed at which the medicinal material is tiled on the vibration platform 4 refers to the speeds of the first roller 411 and the second roller 412. The vibration time and intensity are the vibration parameters of the vibration platform 4, which are realized by controlling the vibration driving member, and different vibration parameters correspond to the operating parameters of the vibration driving member. The number of flips and flip time are the flipping parameters of the vibration platform 4, which are realized by controlling the rotating structure, and different flipping parameters correspond to the operating parameters of the rotating mechanism 43.

[0081] Some embodiments further include:

[0082] Obtain the toxin content and water vapor content of the medicinal material after detoxification and blanking;

[0083] When it is detected that the toxin content and water vapor content do not meet the standards, the medicinal material is transported back to the vibration platform 4, and the laser parameters are adjusted, including extending the irradiation time or increasing the laser power to continue the detoxification treatment.

[0084] Example 1: Detoxification of aconite processing

[0085] Equipment parameter settings:

[0086] Laser wavelength: 980nm (decompose aconitine), 1450nm (solidify polysaccharide).

[0087] Power density: 50W / cm for 980nm laser 2 , 20W / cm for 1450nm laser 2 .

[0088] Conveyor speed: 0.5m / min.

[0089] Processing process:

[0090] Raw aconite is scanned with 980nm laser for 3 minutes, and the residual amount of aconitine detected by GC-IMS and Raman spectroscopy is reduced to 0.008%.

[0091] Switch to 1450nm laser for drying for 2 minutes, and the water content of the medicinal material is reduced to 5%.

[0092] The vibration and flipping platform flips the medicinal material once every 30 seconds to ensure uniform heating.

[0093] Effect verification:

[0094] HPLC detection shows that the degradation rate of aconitine is 92%, and the retention rate of saponins is 97%.

[0095] Compared with the traditional steaming method, the processing time is shortened by 40%, and the energy consumption is reduced by 65%.

[0096] Example 2: Processing of Pinellia ternata to reduce toxicity

[0097] Using 1064nm laser to decompose calcium oxalate raphides and 1330nm laser to promote starch solidification to achieve the removal of irritating components and the retention of medicinal components.
