Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine processing technology, specifically relating to a fully automated processing production line and method for water extract of Alpinia oxyphylla. Background Technology

[0002] Alpinia oxyphylla, a traditional and precious Chinese medicinal herb, has high application value in pharmaceutical preparations, functional health products, and natural food additives due to the presence of terpenoids, phenols, and other active ingredients in its water extract. Market demand continues to rise. In the industrial-scale production of Alpinia oxyphylla water extract, the existing mature process mainly includes key steps such as raw material pretreatment, soaking and stirring extraction, filtration of the mixture, and further processing of the filtrate. The specific operation is as follows: First, the Alpinia oxyphylla raw material is ground into powder of a predetermined particle size, then transported to a mixing tank, and a quantitative extraction solution is added for soaking. To accelerate the full extraction of active ingredients, the mixture is continuously and uniformly stirred using a stirring device. After the extraction reaction is complete, the Alpinia oxyphylla residue is separated using a filtration device to obtain a filtrate containing the target water extract. Finally, the filtrate is transported to the next station for subsequent processing such as concentration and purification.

[0003] In the above process, the quality of raw materials directly determines the safety and efficacy of Alpinia oxyphylla extract. If the raw materials have quality defects, the harmful substances or insufficient efficacy will be directly transmitted to the final product. Therefore, before the raw materials enter the pretreatment stage, strict quality testing must be carried out in accordance with the Pharmacopoeia of the People's Republic of China and relevant industry standards. Unqualified raw materials are strictly prohibited from entering the subsequent processes. The core testing indicators and judgment standards are as follows: the aflatoxin content must be controlled below 5μg / kg, the heavy metals lead ≤5mg / kg, cadmium ≤0.3mg / kg, mercury ≤0.2mg / kg, arsenic ≤2mg / kg, the microbial limits must meet the following requirements: total colony count ≤1000cfu / g, mold and yeast ≤100cfu / g, and the active ingredient Alpinia oxyphylla A content ≥0.2% and volatile oil content ≥0.5mL / g. If any of the above indicators does not meet the standards, it will be judged as unqualified raw material and removed and isolated. Otherwise, it will lead to problems such as excessive heavy metals, microbial contamination or insufficient efficacy in the final product.

[0004] Currently, the industry generally suffers from technical shortcomings in the detection and rejection of Alpinia oxyphylla raw materials. There is no dedicated equipment suitable for industrial conveying scenarios that can achieve integrated "detection and rejection," especially lacking a technical solution that can accurately remove Alpinia oxyphylla one by one from the conveyor belt. The specific drawbacks are as follows:

[0005] Firstly, existing testing methods mostly employ a "sampling inspection + batch judgment" model. This involves randomly selecting a portion of the raw materials from a batch for testing. If a sample fails to meet the standards, the entire batch is deemed unusable. This model has two major drawbacks: Firstly, sampling inspection carries the risk of missed detections. If unqualified raw materials are not included in the sample, they will directly flow into subsequent processing stages, creating potential quality issues. Secondly, the entire batch being scrapped results in the waste of a large amount of qualified raw materials, significantly increasing raw material procurement costs. This is especially true for high-quality Alpinia oxyphylla, where the economic losses are even more pronounced. Some companies have attempted to improve accuracy by using manual, particle-by-particle testing. However, manual testing is extremely inefficient, and the results are highly subjective, influenced by personnel experience and fatigue, failing to meet the efficiency requirements of large-scale industrial production.

[0006] Secondly, existing rejection operations are mostly completed after testing, through manual sorting or batch screening equipment, and both require separation from the main raw material conveying line: manual sorting requires pausing the conveyor line, transferring batches of raw materials to the sorting table, and picking out unqualified products one by one. This not only interrupts the continuous processing flow and reduces the overall production line efficiency, but also poses a risk of secondary contamination due to human contact; batch screening equipment (such as gravity separators and air separators) can only separate raw materials based on physical characteristics such as specific gravity and particle size, and cannot accurately reject raw materials with inherent quality defects such as excessive aflatoxin or heavy metals. The rejection accuracy is not high, so the purity of the raw materials still cannot be guaranteed.

[0007] Third, in the existing process, the testing and conveyor lines are independent of each other. Raw materials need to go through multiple stages of "warehousing-testing-transfer-sorting-retransfer to the conveyor line". This not only increases raw material loss and prolongs the production cycle, but also makes the raw materials susceptible to contact with dust and microorganisms in the external environment during multiple transfers, causing secondary pollution. At the same time, there are compatibility issues in the connection of equipment in each stage, which makes it impossible to achieve an automated closed loop of the processing flow. A lot of manpower is required for transfer and connection operations, which further increases production management costs. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, this invention provides a fully automated processing line for water extracts of Alpinia oxyphylla. This fully automated processing line can automatically perform batch testing, precise removal of individual Alpinia oxyphylla seeds, automatic crushing, and water extraction, thereby improving processing efficiency and reducing processing costs.

[0009] The second objective of this invention is to provide a production method for a fully automated processing line for water extracts of Alpinia oxyphylla.

[0010] The technical solution of the present invention to solve the above-mentioned technical problems is:

[0011] A fully automated processing line for water extract of Alpinia oxyphylla includes a frame, a feeding device, a detection device, a rejection device, a crushing device, a water extract device, and a conveying device mounted on the frame.

[0012] The conveying device includes a conveyor belt, a container for holding Alpinia oxyphylla seeds arranged on the conveyor belt, and a conveying drive mechanism for driving the conveyor belt to move. The container is arranged in multiple groups in a matrix on the conveyor belt. Each container can hold only one Alpinia oxyphylla seed. The bottom of the container is provided with air holes.

[0013] The feeding device is used to transport Alpinia oxyphylla to various containers in the conveyor belt;

[0014] The detection device is used to perform quality detection on the Alpinia oxyphylla on the container and upload the detection results to the control system.

[0015] The rejection device includes a support frame, an air blowing mechanism, an air suction mechanism, and a collection mechanism disposed within the support frame. The air blowing mechanism is located below the conveyor belt; the air suction mechanism is located above the conveyor belt; and the collection mechanism is also located above the conveyor belt and is used to collect defective Alpinia oxyphylla seeds. The control system, based on the detection results from the detection device, controls the air blowing mechanism to blow air into the air holes at the bottom of the container holding the defective Alpinia oxyphylla seeds; simultaneously, it controls the air suction mechanism located above the container to suction upwards. Through the combined effect of the blowing lift and suction, the defective Alpinia oxyphylla seeds are guided away from the container and into the collection mechanism under the airflow guidance.

[0016] The crushing device is used to crush qualified Alpinia oxyphylla, and the Alpinia oxyphylla powder obtained after crushing is quantitatively transported to the water extractor through the conveying module.

[0017] The water extractor is used to soak, extract and filter Alpinia oxyphylla powder to obtain a mixture containing Alpinia oxyphylla water extract.

[0018] A production method for a fully automated processing line for water extracts of Alpinia oxyphylla includes the following steps:

[0019] Step 1: The feeding device delivers Alpinia oxyphylla kernels into the containers located at the feeding station, and each container can only hold one Alpinia oxyphylla kernel.

[0020] Step 2: The conveyor drive mechanism moves the conveyor belt and the container set on the conveyor belt to the testing station. The testing device detects the aflatoxin content, heavy metal content, microbial content, and active ingredient content of the Alpinia oxyphylla at the testing station and sends the test results to the control system. The control system determines whether the quality of the Alpinia oxyphylla in the corresponding container meets the preset quality standard based on the test results. When it is determined that the quality of the Alpinia oxyphylla does not meet the preset quality standard, the control system generates and outputs a rejection control signal to the rejection device.

[0021] Step 3: When the conveyor belt carries the Alpinia oxyphylla to the rejection station, the rejection device rejects the unqualified Alpinia oxyphylla in the container according to the rejection control signal.

[0022] Step 4: After removing the unqualified Alpinia oxyphylla, the conveyor belt continues to carry the Alpinia oxyphylla to the crushing station, where it is crushed by the crushing device to obtain crushed Alpinia oxyphylla powder; the powder is then quantitatively transported to the water extractor via the conveying module.

[0023] Step 5: Add the extractant to the water extractor and extract the water extract from Alpinia oxyphylla by controlling the extraction time and temperature to obtain a crude water extract of Alpinia oxyphylla.

[0024] Step 6: The obtained crude aqueous extract of Alpinia oxyphylla is transported to subsequent purification equipment, vacuum concentration equipment, spray drying equipment and automatic packaging equipment to complete the purification, concentration, drying and packaging processes in sequence, and finally obtain the finished product of Alpinia oxyphylla aqueous extract.

[0025] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0026] 1. The fully automated processing production line for Alpinia oxyphylla water extract of the present invention integrates automatic feeding, continuous conveying, precise sorting, efficient crushing and water extraction processes, realizing integrated automated operation of Alpinia oxyphylla from raw material input to finished product extraction. Compared with the traditional segmented processing mode, the fully automated processing production line for Alpinia oxyphylla water extract of the present invention has a significantly improved degree of automation, which not only effectively shortens the processing cycle, but also significantly improves the overall processing efficiency. At the same time, it reduces manual intervention, reduces labor costs and losses caused by operational errors, thereby achieving effective control of processing costs.

[0027] 2. The fully automated processing line for Alpinia oxyphylla water extract of the present invention enables precise detection of each Alpinia oxyphylla raw material during the conveying process by configuring a detection device on the conveying path; at the same time, it is equipped with a rejection device that is linked to the signal of the detection device, and performs a targeted rejection operation on Alpinia oxyphylla that is determined to be unqualified. This can strictly control the quality of raw materials from the source, thereby effectively preventing unqualified raw materials from flowing into the subsequent extraction process, and thus providing a reliable guarantee for the final processing quality of Alpinia oxyphylla water extract.

Detailed Implementation

[0058] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0059] Example 1

[0060] See Figures 1-10 The fully automated processing line for water extract of Alpinia oxyphylla of the present invention includes a frame, a feeding device 1, a detection device 2, a rejection device 3, a crushing device 6, a water extracting device 7, and a conveying device 4 mounted on the frame.

[0061] The conveying device 4 includes a conveyor belt, a container 401 for holding Alpinia oxyphylla seeds disposed on the conveyor belt, and a conveying drive mechanism for driving the conveyor belt. The container 401 is arranged in multiple groups in a matrix on the conveyor belt; each group of container 401 can hold only one Alpinia oxyphylla seed; the bottom of each container 401 has an air hole; the conveying drive mechanism can be implemented with reference to existing devices, for example, using an active conveying roller, a driven conveying roller, and a conveying motor, wherein the conveyor belt wraps around the active and driven conveying rollers, and the conveyor belt drives the conveyor belt via an electric motor. The machine drives the active conveyor roller to rotate, thereby driving the conveyor belt to move; the holding component 401 can be a holding trough set on the conveyor belt, or a holding box installed on the conveyor belt; in this embodiment, the vertical cross section of the holding component 401 is an isosceles trapezoidal structure with a wider top and a narrower bottom. The internal dimensions of the holding component 401 can be precisely designed according to the average particle size of Alpinia oxyphylla (8-10mm) to ensure that only one Alpinia oxyphylla can be held in a single holding component 401, and the inclination angle of the trapezoidal inner wall is 30-45° to form a guiding structure, which facilitates the Alpinia oxyphylla in the feeding device 1 to slide in and be positioned along the inclined inner wall.

[0062] The feeding device 1 is used to transport Alpinia oxyphylla to each container 401 on the conveyor belt;

[0063] The detection device 2 is used to perform quality detection on the Alpinia oxyphylla on the container 401 and upload the detection results to the control system.

[0064] The rejection device 3 is used to reject each unqualified Alpinia oxyphylla one by one;

[0065] The crushing device 6 is used to crush qualified Alpinia oxyphylla, and the crushed Alpinia oxyphylla powder is quantitatively transported to the water extractor 7 through the conveying module. In this embodiment, the crushing device 6 can be an existing crushing device 6, which drives the crushing blade group to rotate through the crushing motor, thereby crushing Alpinia oxyphylla in the crushing chamber to obtain Alpinia oxyphylla powder.

[0066] The water extractor 7 is used to soak, extract and filter Alpinia oxyphylla powder to obtain a mixture containing Alpinia oxyphylla water extract. In this embodiment, the water extractor 7 can be implemented using an existing stirring and filtering extraction device, such as the "a continuous extraction device for tea polyphenols" disclosed in the invention patent application with publication number CN119680250A, or the "water extractor" described in Example 4.

[0067] See Figures 1-10The feeding device 1 can be an existing vibrating feeder, or it can have the following structure, namely, a hopper 101 mounted on the frame, a feeding mechanism mounted below the hopper 101, and a vibration mechanism 103 for causing the feeding mechanism to vibrate. The hopper 101 and the feeding mechanism are not fixedly connected, but can move relative to each other. The vibration mechanism 103 is only used to drive the feeding mechanism to vibrate.

[0068] The feeding mechanism includes a first vibrating plate 104 and a second vibrating plate 102 connected to the first vibrating plate 104; the driving end of the vibration mechanism 103 is connected to the first vibrating plate 104; one end of the second vibrating plate 102 is connected to the first vibrating plate 104, and the other end is a free end that can swing up and down; wherein, the bottom surface height of the first vibrating plate 104 is higher than the bottom surface height of the second vibrating plate 102, and the thickness of the connection part 105 between the first vibrating plate 104 and the second vibrating plate 102 is less than the thickness of the second vibrating plate 102 and the first vibrating plate 104, so that the second vibrating plate 102 can swing up and down with the support point of the connection part 105; the second vibrating plate 102 is provided with multiple sets of conveying grooves arranged along the conveying direction perpendicular to the Alpinia oxyphylla, and the conveying grooves are V-shaped grooves; the number of conveying grooves is the same as the number of holding pieces 401 arranged along the width direction of the conveyor belt, and the end of each set of conveying grooves is located above the corresponding holding piece 401.

[0069] The vibration mechanism 103 outputs a vibration frequency that is the same as the natural frequency of the feeding mechanism to excite the feeding mechanism to undergo modal resonance. This modal resonance couples with the vibration action of the vibration mechanism 103 to form a composite vibration. The composite vibration causes the Alpinia oxyphylla to change from a stacked state to a single-layer, single-row arrangement while continuing to move towards the end of the second vibrating plate 102. In this embodiment, the vibration mechanism 103 is a linear vibrator, which is mounted obliquely on the frame. The drive end of the linear vibrator is connected to the first vibrating plate 104, so that the excitation of the linear vibrator will be completely transmitted to the feeding mechanism.

[0070] The feeding device 1 in this invention, based on traditional vibratory conveying, generates composite vibration by combining externally excited vibration with resonance caused by the external excitation. The condition for resonance is that the external excitation frequency is close to the natural frequency of the feeding structure, and the closer the external excitation frequency is to the natural frequency, the larger the resonance amplitude. Based on this characteristic, the mode shape and amplitude of the resonance of the feeding mechanism can be adjusted by adjusting the external excitation frequency. After coupling the externally excited vibration with the feeding mechanism's resonance at different orders, a controllable composite vibration is formed, thereby achieving the effect of adjusting the feeding of Alpinia oxyphylla. Under the action of composite vibration, the movement of Alpinia oxyphylla mainly consists of two parts: one is the oblique vibration generated by the linear vibrator (e.g., ...). Figure 10 The force (in the V1 direction) can be decomposed into a vertical component (causing the Alpinia oxyphylla to jump upwards) and a horizontal component (causing the Alpinia oxyphylla to move forwards); this causes the Alpinia oxyphylla to move towards the discharge port of the second vibrating plate 102 by sliding or jumping; secondly, when the vibration frequency is close to the natural frequency of the feeding mechanism, the second vibrating plate 102 resonates, producing significant vibration amplification, causing the second vibrating plate 102 to swing up and down (as shown in the image). Figure 10 (V2 direction in the middle); resonance mainly provides the vertical vibration amplitude, making the Alpinia oxyphylla be tossed up and fall more violently; in this process, the Alpinia oxyphylla in the lower layer is in direct contact with the second vibration disk 102 and is directly driven by the vibration of the second vibration disk 102. The vibration of the Alpinia oxyphylla in the lower layer is transmitted to the Alpinia oxyphylla in the upper layer through interaction. Since the gravity (and other forces in the direction of gravity) of the Alpinia oxyphylla in the upper layer is smaller and it is driven more indirectly, the motion amplitude of the Alpinia oxyphylla in the upper layer is relatively small and there is a phase difference with the Alpinia oxyphylla in the lower layer, thus producing relative displacement; and the motion of the Alpinia oxyphylla mentioned above occurs cyclically in each vibration cycle. In addition, during the entire process of the Alpinia oxyphylla moving from the conveying groove to the discharge port of the second vibrating plate 102, it continuously and frequently undergoes a cycle of "throwing up-separating-falling". At the same time, the conveying groove restricts the lateral movement of the Alpinia oxyphylla, forcing it to move only along a predetermined path. This causes the Alpinia oxyphylla in two or more layers to separate from the stacked state, so that the originally randomly stacked Alpinia oxyphylla is gradually arranged into a single layer and a single row of orderly state. When the Alpinia oxyphylla is closer to the end of the conveying groove, the upward motion component is greater. Therefore, the Alpinia oxyphylla will flow back and accumulate in the area with less movement (i.e., the position near the first vibrating plate 104), thereby reducing the number of Alpinia oxyphylla at the end of the conveying groove, thus forming a flat layer at the end of the conveying groove. This is conducive to the Alpinia oxyphylla falling one by one into the container 401 located at the loading station.

[0071] As a preferred embodiment, since each container 401 is only suitable for holding one Alpinia oxyphylla kernel, to avoid problems such as decreased detection accuracy and deviation in rejection actions caused by multiple Alpinia oxyphylla kernels being mixed in the same container 401, this embodiment adds a curtain mechanism (not shown in the attached drawings) between the loading station and the detection station of the production line to achieve automatic sorting in the case of multiple kernels being mixed in, ensuring that the container 401 entering the detection stage contains only a single Alpinia oxyphylla kernel; wherein, the curtain mechanism is installed on the frame between the loading station and the detection station, and directly above the conveyor belt, and consists of two parts: a fixed frame and a flexible curtain; wherein, the fixed frame is bolted to the frame to ensure that The curtain mechanism remains stable under the vibration environment generated by the high-speed operation of the conveyor belt, avoiding the impact of mechanism shaking on sorting accuracy. The flexible curtain can be made of food-grade elastic material, which has both excellent structural strength and flexibility. On the one hand, it can effectively block excess Alpinia oxyphylla kernels, and on the other hand, it can generate an elastic buffer when in contact with Alpinia oxyphylla kernels, avoiding mechanical damage to the raw material. It can also prevent scratching the surface of the container 401. To achieve accurate sorting, the distance between the lower end of the flexible curtain and the top opening of the container 401 must be less than the overall height of a single Alpinia oxyphylla kernel, and greater than the top protrusion height of a single Alpinia oxyphylla kernel when placed in the container 401.

[0072] The working process of the curtain mechanism in this embodiment is as follows: When the conveyor belt drives the container 401 to pass under the curtain mechanism at a constant speed, if there is only one Alpinia oxyphylla in the container 401, since the top of the Alpinia oxyphylla protruding is less than the distance between the flexible curtain and the top of the container 401, it can pass smoothly through the flexible curtain area and enter the subsequent inspection station; if there are two or more Alpinia oxyphylla in the container 401, the excess Alpinia oxyphylla will protrude from the top of the container 401, and its overall protrusion height is greater than the above-mentioned curtain spacing. When passing through the flexible curtain, it will be blocked and separated by the flexible curtain; the separated excess Alpinia oxyphylla falls into the preset recycling troughs on both sides of the conveyor belt, realizing automatic sorting of multiple mixed particles.

[0073] By setting up the aforementioned curtain mechanism, the quantity of Alpinia oxyphylla in the container 401 can be accurately controlled before the inspection process, ensuring that the subsequent inspection module can accurately inspect each Alpinia oxyphylla. It also provides a stable prerequisite for subsequent targeted rejection actions, ensuring the reliability of the production line inspection and rejection process.

[0074] See Figures 1-10 The detection device 2 includes a first detection module, a second detection module, a third detection module, and a fourth detection module arranged sequentially along the conveying direction of the Alpinia oxyphylla, wherein...

[0075] The first detection module is used to detect the aflatoxin content in Alpinia oxyphylla and output the first detection information to the control system. In this embodiment, the first detection module uses a near-infrared spectrometer. By irradiating Alpinia oxyphylla with near-infrared light (wavelength 780-2500nm), the absorption and scattering characteristics of aflatoxin and Alpinia oxyphylla matrix components to near-infrared light are different. By collecting the near-infrared spectral signal of the sample and combining it with a chemometric model (such as partial least squares method, artificial neural network), the rapid quantitative detection of aflatoxin content is achieved. The first detection information containing aflatoxin content data is generated and transmitted to the control system through an Ethernet interface.

[0076] The second detection module is used to detect the heavy metal content in Alpinia oxyphylla and output the second detection information to the control system. In this embodiment, the second detection module uses an X-ray fluorescence spectrometer, which covers common heavy metals such as lead, cadmium, mercury, and arsenic. Its working principle is as follows: X-rays with an energy of 10-40 keV are emitted through an X-ray tube to non-contactly irradiate Alpinia oxyphylla in the container 401. The heavy metal elements are excited and generate characteristic X-rays. The X-ray fluorescence spectrometer collects characteristic X-ray signals through a detector, and the content of each heavy metal element is obtained by the spectral analysis module. The second detection information containing the content data of each heavy metal element is generated and transmitted to the control system through an Ethernet interface.

[0077] The third detection module is used to detect the microbial content in Alpinia oxyphylla and output the third detection information to the control system. In this embodiment, the third detection module adopts a non-contact laser-induced fluorescence detector. The specific implementation process is as follows: the laser emission module of the non-contact laser-induced fluorescence detector emits a pulsed laser of a specific wavelength (355nm) to the surface of Alpinia oxyphylla in the container 401. After the pulsed laser penetrates the surface tissue of Alpinia oxyphylla, it excites the inherent fluorescent substances (such as NADH, tryptophan, etc.) in the microorganisms to produce characteristic fluorescence. The non-contact fluorescence receiving probe collects fluorescence signals at a distance of 8cm from the surface of the raw material. Through the built-in signal processing unit, the fluorescence intensity, fluorescence lifetime and other parameters are converted into total microbial colony data. After generating the third detection information, it is sent to the control system through the wireless transmission module.

[0078] The fourth detection module is used to detect the content of effective components in Alpinia oxyphylla and output the fourth detection information to the control system. In this embodiment, the fourth detection module uses a Fourier transform near-infrared spectrometer to detect effective components such as volatile oils and flavonoids in Alpinia oxyphylla. Its working principle is as follows: near-infrared light is emitted through a non-contact near-infrared light irradiation device, which penetrates the Alpinia oxyphylla sample in the container 401 and collects the near-infrared absorption spectrum of the sample; the absorption spectrum is analyzed using a preset partial least squares regression model to obtain the content data of effective components, and the fourth detection information containing the content data of effective components is generated and transmitted to the control system through the RS232 interface.

[0079] After receiving the first, second, third, and fourth detection information, the control system processes and analyzes the information to determine whether the quality of the Alpinia oxyphylla in the corresponding container 401 meets the preset quality standard. When the quality of the Alpinia oxyphylla does not meet the preset quality standard, the control system generates and outputs a rejection control signal. When the container 401 containing the defective Alpinia oxyphylla is transported to the rejection station, the rejection device 3 performs a rejection operation on the Alpinia oxyphylla in the container 401 according to the rejection control signal.

[0080] In this embodiment, the following judgment rule can be adopted:

[0081] When any one of the aflatoxin content, heavy metal content, microbial content, and effective ingredient content output by the first, second, third, and fourth detection modules fails to meet the preset safety and quality standards, the control system directly determines that the Alpinia oxyphylla is a substandard product and triggers the rejection device 3 to remove it from the production line, prohibiting it from entering the subsequent processing stage.

[0082] When the aflatoxin content, heavy metal content, microbial content, and active ingredient content all meet the preset quality standards, the control system inputs these parameters into a preset AI quality recognition model. The model then calculates and outputs the quality assessment result for the product.

[0083] The AI ​​quality identification model adopts a convolutional neural network (CNN) architecture. Its input layer consists of 7-10 dimensions of feature data, including aflatoxin content, heavy metal (lead, cadmium, mercury, arsenic, etc.) content, total microbial colony count, and volatile oil and flavonoid content. The output layer of the AI ​​quality identification model is the predicted content of the water extract that can be obtained after extracting the Alpinia oxyphylla. The training process of the AI ​​quality identification model is as follows: collect the above-mentioned multi-dimensional indicator data of Alpinia oxyphylla in historical production and the corresponding actual water extract content as label data. After data cleaning and normalization preprocessing, the data is divided into training set and test set. The model parameters are optimized through backpropagation algorithm. By continuously adjusting structural parameters such as convolution kernel size and the number of neurons in fully connected layers, the prediction error of the model is lower than a preset threshold, and the trained AI quality identification model is obtained.

[0084] The control system inputs real-time detected multi-dimensional index data into the trained AI quality recognition model to obtain the predicted water extract yield. The control system compares the predicted water extract yield with a preset threshold: if the predicted water extract yield is greater than or equal to the preset threshold, the Alpinia oxyphylla is determined to be a qualified product and is allowed to enter the subsequent processing stage; if the predicted water extract yield is less than the preset threshold, the Alpinia oxyphylla is determined to be a defective product and the rejection device 3 is triggered to reject it, so as to avoid the low extraction rate raw material affecting the processing efficiency of the production line and product revenue.

[0085] In this embodiment, the first detection module, the second detection module, the third detection module, and the fourth detection module can all be integrated into a closed black box, and the conveyor belt passes through the black box. Through the light-shielding and dust-proof structure design of the black box, a stable detection environment is provided for each detection module, avoiding interference factors such as external light and dust from affecting the detection accuracy. At the same time, the detection process is closed and standardized, ensuring the accuracy and repeatability of the detection results.

[0086] In addition to the non-contact detection methods listed above, the first detection module, the second detection module, the third detection module and the fourth detection module may also adopt other existing non-contact detection methods, and their structures can be implemented with reference to existing devices.

[0087] See Figures 1-10The rejection device 3 includes a support 301, an air blowing mechanism, an air suction mechanism, and a collection mechanism disposed in the support 301. The air blowing mechanism is located below the conveyor belt; the air suction mechanism is located above the conveyor belt; and the collection mechanism is also located above the conveyor belt, used to collect unqualified Alpinia oxyphylla seeds. The control system, based on the detection result of the detection device 2, controls the air blowing mechanism to blow air upwards through the air holes at the bottom of the container 401 containing the unqualified Alpinia oxyphylla seeds; simultaneously, it controls the air suction mechanism located above the container 401 to suction upwards. Through the synergistic effect of the blowing lift and suction, the unqualified Alpinia oxyphylla seeds are guided away from the container 401 and enter the collection mechanism under the airflow guidance.

[0088] The air blowing mechanism includes air jet components 302 mounted on a support 301; the air jet components 302 are multiple sets, and the multiple sets of air jet components 302 are equidistantly arranged along a direction perpendicular to the width of the conveyor belt; and correspond one-to-one with the multiple sets of containers 401 equidistantly arranged along their width direction on the conveyor belt; each set of air jet components 302 includes a nozzle and a first control valve group for adjusting the air pressure of the gas ejected from the nozzle; the air inlet of the nozzle is connected to the air supply device through a gas pipe; the first control valve group includes a solenoid valve and a pressure regulating valve, wherein the solenoid valve is used to control the opening and closing of the gas pipe; the pressure regulating valve is used to control the pressure of the gas pipe; the control system is connected to the solenoid valve and the pressure regulating valve respectively.

[0089] The air suction mechanism includes suction components mounted on a support 301; the suction components are in multiple sets, and these sets are equidistantly arranged along a direction perpendicular to the width of the conveyor belt; and each set corresponds to a container 401 equidistantly arranged along its width direction on the conveyor belt; each suction component includes a box 304, a suction nozzle 305 disposed within the box 304, and a second control valve group for adjusting the suction force of the suction nozzle 305 (the structure of the second control valve group can be implemented with reference to the structure of the first control valve group); a guide component is provided within the box 304 for guiding the Alpinia oxyphylla into the collection mechanism; the guide component divides the space within the box 304 into a first region, a second region, and a third region, wherein the first region is connected to the material inlet 311 in the box 304; the second region is connected to the air inlet of the suction nozzle 305; and the third region is connected to the material outlet of the box 304; the guide component The enclosure includes a first baffle 308 located between the first and second regions and a second baffle 309 located between the second and third regions. The first baffle 308 is inclined, with its lowest end hinged within the housing 304, and its highest end abutting against a support block 307 installed within the housing 304. The second baffle 309 includes a hinge portion and a first flat plate portion and a second flat plate portion disposed on both sides of the hinge portion. The hinge portion is hinged within the housing 304. The first flat plate portion and the second flat plate portion are angled together, with the first flat plate portion located within the housing 304 and the second flat plate portion located outside the housing 304. A counterweight 310 is disposed on the second flat plate portion. The weight of the counterweight 310 causes the second baffle 309 to rotate upward until the upper side of the free end of the first flat plate portion abuts against the lowest end of the first baffle 308.

[0090] The collection mechanism includes a collection trough 303 disposed on the support 301 and a spiral pushing mechanism 306 disposed in the collection trough 303; the material outlets of the boxes 304 in the multiple sets of suction components are all connected to the collection trough 303; the end of the collection trough 303 is provided with a discharge port, which can be connected to a collection container through a pipe for collecting unqualified Alpinia oxyphylla.

[0091] With the above configuration, the working principle of the rejection device 3 in this invention is as follows:

[0092] When the alpinia oxyphylla to be removed arrives at the removal station, the jet assembly 302 located at the bottom of the alpinia oxyphylla activates. The nozzle in the jet assembly 302 blows high-pressure gas through the air hole at the bottom of the container 401. This high-pressure gas, passing through the air hole, causes the alpinia oxyphylla inside the container 401 to move upwards. Simultaneously, the suction assembly in the air suction mechanism also activates, with the suction nozzle 305 drawing in air, creating a negative pressure in the second region of the box 304. Under the combined upward blowing force of the nozzle and the upward suction force of the suction nozzle 305, the first baffle 308 rotates counterclockwise, connecting the first and second regions. The alpinia oxyphylla to be removed is then guided into the second region by the upward blowing and suction forces. Once the alpinia oxyphylla is detected... Upon entering the second area, the suction nozzle 305 and the nozzle stop working, causing the first baffle 308 to rotate clockwise under its own gravity and be supported on the support block 307, thereby separating the first area and the second area again. The Alpinia oxyphylla entering the second area, guided by the inclined first baffle 308, will contact the first flat plate portion of the second baffle 309. The gravity of the Alpinia oxyphylla causes the second baffle 309 to rotate clockwise, thereby connecting the second area with the third area. This allows the Alpinia oxyphylla to enter the third area and fall into the collection trough 303 after passing through the material outlet. The spiral pushing mechanism 306 drives the movement of the Alpinia oxyphylla in the collection trough 303, pushing these defective Alpinia oxyphylla into the corresponding collection container.

[0093] In the above process, a guide opening that is wider at the bottom and narrower at the top can be provided below the material inlet 311 of the box body 304 (e.g., Figure 6 As shown in the figure, so that the Alpinia oxyphylla to be removed can pass smoothly through the material inlet 311 and enter the box 304.

[0094] See Figures 1-10The detection device 2 further includes a visual positioning module (e.g., a camera or industrial camera) for collecting the position information of the Alpinia oxyphylla in the container 401; the visual positioning module is mounted on the bracket 301 and is used to detect the Alpinia oxyphylla that has reached the rejection station to obtain the position information of the Alpinia oxyphylla in the container 401; in addition, the bottom of the container 401 has multiple sets of air holes, which are divided into a first air hole 402 located at the center of the container 401 and a second air hole 402 located around the first air hole 402. Two air holes 403 are provided, wherein the axis of the first air hole 402 passes through the center of the container 401; the second air hole 403 is inclined and the extended axes of each second air hole 403 converge at the same point, and the convergence point is located on the extended axis of the first air hole 402, forming a "center-focused" airflow field structure; correspondingly, the nozzle is provided with a first air outlet and a second air outlet at the corresponding positions of the first air hole 402 and the second air hole 403; the first air outlet and the second air outlet can be controlled independently.

[0095] When the Alpinia oxyphylla is transported to the rejection station along with the container 401, the visual positioning module is activated and collects real-time image information of the Alpinia oxyphylla to be rejected, and uploads the image information to the control system. After preprocessing the image information such as grayscale conversion, edge extraction, and contour recognition, the control system calculates the center of gravity position of the Alpinia oxyphylla to be rejected through image algorithms (establishing a coordinate system with the center of the container 401 as the origin and outputting the center of gravity coordinate data). The control system calculates the difference between the calculated center of gravity position of the Alpinia oxyphylla and the center position of the preset container 401. If the deviation exceeds the allowable range, a position correction signal is generated. This position correction signal includes parameters such as the target correction direction, airflow intensity, and duration. The control system matches the corresponding nozzle according to the position correction signal and drives one or more sets of second air outlets in the nozzle to open and blow out airflow. Through the thrust of the directional airflow, the Alpinia oxyphylla to be rejected is displaced within the container 401 until the deviation between its center of gravity position and the center position of the container 401 is reduced to within the allowable range, thus completing the position correction. This is mainly for Alpinia oxyphylla with relatively small dimensions. After the position correction is completed, the control system outputs a rejection control signal according to the preset rejection command. Based on the rejection control signal, the first air outlet in the nozzle is activated and outputs rejection airflow. The airflow acts precisely on the Alpinia oxyphylla in the corrected position, blowing it out of the container 401, thus achieving precise rejection of unqualified Alpinia oxyphylla.

[0096] In this embodiment, the visual positioning module is directly integrated into the rejection device 3, forming an integrated "detection-correction-rejection" structure. Before executing the rejection action, the visual positioning module first detects the position of the Alpinia oxyphylla to be rejected in the container 401. The control system drives the relevant air outlet of the rejection device 3 to blow out directional airflow according to the detection result, thereby correcting the position of the Alpinia oxyphylla and then immediately executing the rejection operation. This can shorten the work process and improve rejection efficiency. Alternatively, the visual positioning module can also be set at the upstream station of the rejection device 3 to achieve pose pre-correction. The visual positioning module first accurately detects the real-time position of the Alpinia oxyphylla to be rejected and uploads the position information to the control system. The control system drives the air blowing mechanism set below the visual positioning module to perform pose correction of the Alpinia oxyphylla through directional airflow. When the pre-corrected Alpinia oxyphylla is transported to the rejection station with the container 401, it can directly match the action parameters of the rejection device 3 to achieve rapid rejection of unqualified Alpinia oxyphylla, thereby reducing the response time of the rejection station.

[0097] Furthermore, the aforementioned visual inspection and air-blowing posture correction technologies can also be simultaneously applied to the inspection processes of each inspection module. When the Alpinia oxyphylla flows between different inspection modules along with the container 401, the control system triggers the visual positioning module and air-blowing mechanism of the corresponding workstation to work together according to the inspection requirements of the corresponding inspection module. The visual positioning module monitors the posture of the Alpinia oxyphylla in real time, and the air-blowing mechanism outputs directional airflow based on the monitoring results and the weight of the Alpinia oxyphylla to drive the Alpinia oxyphylla in the container 401 to complete actions such as flipping and fine-tuning. This ensures that different surfaces and areas of the Alpinia oxyphylla are fully exposed to the inspection area of ​​the corresponding inspection module, ensuring that each inspection module can achieve all-round, blind-spot-free inspection of the Alpinia oxyphylla, thereby improving the accuracy and comprehensiveness of the inspection data.

[0098] See Figures 1-10A pressure sensor is installed at the bottom of the container 401. This pressure sensor is connected to the control system and is used to collect the weight data of the Alpinia oxyphylla entering the container 401 in real time, and transmit the weight information synchronously to the control system. The control system has a built-in preset air pressure calculation model. This air pressure calculation model uses the weight of the Alpinia oxyphylla as the core input parameter and calculates the nozzle blowing force and suction force values ​​that match the weight of the Alpinia oxyphylla to be removed through preset algorithms (such as linear fitting algorithm and neural network algorithm), so as to ensure that the blowing force and suction force can stably drive the Alpinia oxyphylla to detach. The container 401 prevents breakage of the Alpinia oxyphylla due to excessive pressure or rejection failure due to insufficient pressure. It also ensures that all defective Alpinia oxyphylla from the same batch are rejected at the same time, thus improving rejection efficiency. The control system integrates the corresponding blowing and suction control parameters into the rejection control signal based on the output of the air pressure calculation model. This rejection control signal then drives the corresponding air pressure regulating valve to adjust the jet pressure of the nozzle and the suction pressure of the suction nozzle 305, precisely matching the weight requirements of the Alpinia oxyphylla to be rejected. Once the pressure is adjusted, the nozzle and suction nozzle 305 work together to accurately and efficiently reject defective Alpinia oxyphylla while ensuring that surrounding qualified Alpinia oxyphylla are not affected by the airflow.

[0099] Furthermore, the image information of the Alpinia oxyphylla detected by the visual positioning module and the weight information of the Alpinia oxyphylla detected by the pressure sensor can both serve as supplementary input parameters for the AI ​​quality recognition model, and can be input into the model in conjunction with data such as aflatoxin content, heavy metal content, microbial content, and effective ingredient content. Among these, the weight information reflects the basic quality characteristics of the Alpinia oxyphylla, such as its plumpness and developmental state. Through the fusion training and recognition of multi-dimensional parameters, the accuracy of the AI ​​quality recognition model in judging the quality of Alpinia oxyphylla can be further improved, providing more reliable data support for subsequent screening and elimination decisions. Additionally, the weight information of the Alpinia oxyphylla monitored by the pressure sensor can also be used as a basis for position correction.

[0100] See Figures 1-10The frame is equipped with a collection box 5 at the end of the conveyor belt; the discharge port of the collection box 5 is connected to the feed port of the crushing device 6 through a first conveying pipe; the discharge port of the crushing device 6 is connected to the feed port of the water extraction device 7 through a second conveying pipe; to ensure a stable material supply for each processing stage and to avoid affecting processing efficiency and product quality due to excessive or insufficient material, the first and second conveying pipes are both equipped with the aforementioned conveying modules; in this embodiment, the conveying module adopts a flexible screw conveyor. This flexible screw conveyor, with its flexible conveying characteristics, can adapt to the installation path of the pipe and can precisely control the material conveying amount, ensuring that the feed amount to the crushing device 6 and the water extraction device 7 meets the preset processing parameters, thus achieving coordinated matching between each process.

[0101] In this embodiment, an integrated protective cover is provided on the frame along the conveyor belt's conveying direction. The protective cover and the black box containing the aforementioned detection module are designed with a sealed connection, forming a fully enclosed conveying channel from raw material feeding to detection and discharge. The protective cover is made of transparent antistatic material, which can isolate external dust, microorganisms, light and other interference factors, preventing the Alpinia oxyphylla on the conveyor belt from being contaminated or deteriorating in quality, ensuring the cleanliness of the raw materials and the accuracy of detection. It also allows operators to observe the conveying status in real time. At the same time, the antistatic design prevents the raw materials from adsorbing impurities due to static electricity, further improving the quality control effect of the raw materials.

[0102] See Figures 1-10 The fully automated processing method for water extract of Alpinia oxyphylla of the present invention includes the following steps:

[0103] Step 1: The feeding device 1 feeds the Alpinia oxyphylla kernel into the container 401 located at the feeding station, and each container 401 can only hold one Alpinia oxyphylla kernel.

[0104] Step 2: The conveyor drive mechanism drives the conveyor belt and the container 401 mounted on the conveyor belt to the testing station. The testing device 2 detects the aflatoxin content, heavy metal content, microbial content, and active ingredient content of the Alpinia oxyphylla located at the testing station, and sends the test results to the control system. The control system determines whether the quality of the Alpinia oxyphylla in the corresponding container 401 meets the preset quality standard based on the test results. When it is determined that the quality of the Alpinia oxyphylla does not meet the preset quality standard, the control system generates and outputs a rejection control signal to the rejection device 3.

[0105] Step 3: When the conveyor belt carries the Alpinia oxyphylla to the rejection station, the rejection device 3 rejects the unqualified Alpinia oxyphylla in the container 401 according to the rejection control signal.

[0106] Step 4: After removing the unqualified Alpinia oxyphylla, the conveyor belt continues to carry the Alpinia oxyphylla to the crushing station, where it is crushed by the crushing device 6 to obtain crushed Alpinia oxyphylla powder; the powder is then quantitatively conveyed to the water extractor 7 by the conveying module.

[0107] Step 5: Add the extractant to the water extractor 7, and extract the water extract from Alpinia oxyphylla by controlling the extraction time and extraction temperature to obtain a crude water extract of Alpinia oxyphylla.

[0108] Step 6: The obtained crude aqueous extract of Alpinia oxyphylla is transported to subsequent purification equipment, vacuum concentration equipment, spray drying equipment and automatic packaging equipment to complete the purification, concentration, drying and packaging processes in sequence, and finally obtain the finished product of Alpinia oxyphylla aqueous extract.

[0109] Example 2

[0110] The difference between this embodiment and Embodiment 1 is that the rejection device 3 consists of two sets. One set of rejection devices 3 is used to reject Alpinia oxyphylla seeds that exceed the standards for either aflatoxin content or heavy metal content. The second set of rejection devices 3 is used to reject and collect Alpinia oxyphylla seeds that exceed the standards for microbial content. By grouping the two sets of rejection devices 3, the unqualified Alpinia oxyphylla seeds with different types of contamination can be classified and processed. For the collected Alpinia oxyphylla seeds with excessive microbial content, further specialized processing operations can be carried out: for example, using compliant processes such as high-temperature sterilization or low-temperature plasma sterilization to reduce their microbial content. After re-inspection confirms that the microbial indicators meet the preset quality standards, they can be reintroduced into the production line for processing. This achieves resource utilization of unqualified raw materials, effectively reduces raw material loss rate, and improves the economic efficiency of the production line.

[0111] Example 3

[0112] The difference between this embodiment and Embodiment 1 is that a sterilization module is installed on the lower side of the conveyor belt. This sterilization module is connected to the control system signal and its installation position corresponds to the return section of the conveyor belt (i.e., the conveyor section where the container 401 has been unloaded and has not entered the next round of feeding). It is used to clean and disinfect the interior of the container 401 carried by the conveyor belt for aflatoxin and microorganisms, so as to avoid residual contaminants affecting the detection accuracy and processing safety of subsequent batches of Alpinia oxyphylla. In this embodiment, the sterilization module adopts a composite sterilization structure of "ultraviolet sterilization + ozone assistance". The control system adaptively starts the sterilization module according to the raw material contamination data fed back by the detection module. When the container 401 passes through the sterilization area at a constant speed of 0.5m / s with the conveyor belt, the 30W ultraviolet lamp group... The interior of container 401 is continuously irradiated, while an ozone generator releases ozone at a concentration of 0.4 mg / m³. The ultraviolet light and ozone work synergistically: on the one hand, the ultraviolet light directly destroys the DNA double-strand structure of microorganisms, achieving rapid killing; on the other hand, the ozone oxidizes and decomposes the molecular structure of aflatoxin, rendering it non-toxic. After disinfection, container 401 continues to run with the conveyor belt until the ozone naturally decomposes to a safe concentration (≤0.02 mg / m³) before entering the next feeding process. By adding this sterilization module under the conveyor belt, the entire process of disinfection of container 401 can be achieved, blocking the residual path of pollutants from the source, completely avoiding cross-contamination between different batches of Alpinia oxyphylla, and ensuring that the testing environment of the subsequent testing module is not contaminated, greatly improving the accuracy of testing data and the processing safety of the production line.

[0113] Example 4

[0114] See Figures 11-28 The difference between this embodiment and Embodiment 1 is that the water extraction device 7 in this embodiment includes a base frame, a stirring tank 42 mounted on the base frame, a filtration and stirring mechanism disposed within the stirring tank 42, and a function switching mechanism for driving the filtration and stirring mechanism to switch between filtration mode and stirring mode.

[0115] The mixing tank 42 is equipped with a feed inlet 421, a liquid inlet (not shown in the accompanying drawings), a discharge outlet 423, and a liquid outlet 422. The feed inlet 421 is used for a second external conveying pipe to quantitatively transport the crushed Alpinia oxyphylla powder into the mixing tank 42. The liquid inlet is used to supply the extraction liquid (e.g., hot water) into the mixing tank 42. The liquid outlet 422 is used to discharge the filtrate of the filtered Alpinia oxyphylla aqueous extract to the next processing station after extraction. The discharge outlet 423 is used to discharge the filter residue after extraction for further processing.

[0116] The filtering and stirring mechanism includes multiple sets of filter plates 15 and hinge shafts disposed between adjacent sets of filter plates 15, wherein both sides of adjacent sets of filter plates 15 are hinged to the same hinge shaft; each set of filter plates 15 is provided with filter holes; the function switching mechanism is used to drive some of the hinge shafts to make radial movements. When all the hinge shafts move to the outermost side (i.e., the maximum radial outward movement of each hinge shaft), the two sides of the multiple sets of filter plates 15 are connected in sequence to form a filter barrel, and the filtering and stirring mechanism is in filtering mode at this time; when all the hinge shafts move to the innermost side (i.e., the maximum radial inward movement of each hinge shaft), the two sides of the multiple sets of filter plates 15 are connected in sequence to form stirring blades, and the filtering and stirring mechanism is in stirring mode at this time.

[0117] In this embodiment, the water extraction device 7 can extract water extracts from Alpinia oxyphylla. Alpinia oxyphylla powder is fed into a mixing tank 42, and then an extractant is added. A function switching mechanism first switches the filtration and stirring mechanism to stirring mode, transforming it into a stirring fan blade, which rotates to stir the extractant in the mixing tank 42, thereby accelerating the rapid precipitation of water extracts from the Alpinia oxyphylla powder. After a predetermined time, the function switching mechanism switches the filtration and stirring mechanism to filtration mode, transforming it into a filter barrel, to filter the mixture in the mixing tank 42 after water extraction. The filtrate obtained after filtration is located inside the filter barrel and is discharged through an outlet 422, also located within the filter barrel, and transported to the next processing station.

[0118] See Figures 11-28 The function switching mechanism includes a bracket, a drive disk 46 mounted on the bracket, and a rotary drive mechanism for driving the drive disk 46 to rotate.

[0119] The drive disk 46 is provided with multiple sets of arc-shaped drive grooves 461, and the distance between the arc-shaped drive groove 461 and the center of the drive disk 46 gradually increases along the extension direction of the arc-shaped drive groove 461; wherein the upper end of part of the hinge shaft extends into the arc-shaped drive groove 461.

[0120] When the rotary drive mechanism drives the drive disk 46 to rotate in the forward direction, the drive disk 46 drives multiple sets of hinge shafts (i.e., "second hinge shaft 34" hereinafter) to move radially outward, so as to cause multiple sets of filter plates 15 to open to form a filter barrel; when the rotary drive mechanism drives the drive disk 46 to rotate in the reverse direction, the drive disk 46 drives multiple sets of hinge shafts (i.e., "second hinge shaft 34" hereinafter) to move radially inward, so as to cause multiple sets of filter plates 15 to fold to form stirring blades and drive the stirring blades to rotate to achieve the stirring function.

[0121] See Figures 11-28The function switching mechanism further includes a switching guide mechanism, which includes a guide disk 47 and multiple sets of radially extending guide grooves disposed in the guide disk 47.

[0122] The guide disk 47 is located below the drive disk 46 and is coaxially arranged with the drive disk 46; multiple sets of guide grooves are arranged along the circumference of the guide disk 47.

[0123] The guide groove is divided into a first guide groove 471 and a second guide groove 472, which are alternately arranged along the circumferential direction of the guide disk 47. The upper ends of some hinge shafts extend into the first guide groove 471, while the upper ends of the remaining hinge shafts pass through the second guide groove 472 and enter the arc-shaped drive groove 461. The hinge shaft extending into the first guide groove 471 is the first hinge shaft 33, and the hinge shaft extending into the second guide groove 472 and the arc-shaped drive groove 461 is the second hinge shaft 34. Similarly, the first hinge shaft 33 and the second hinge shaft 34 are alternately arranged along the circumferential direction of the guide disk 47 / drive disk 46.

[0124] With the above configuration, when the rotary drive mechanism drives the drive disk 46 to rotate in the forward direction, the drive disk 46 drives multiple sets of second hinge shafts 34 to move radially outward. Simultaneously, as the second hinge shafts 34 move actively, in order to adapt to this deformation from the stirring blades to the filter barrel, the first hinge shaft 33 also undergoes an adaptive movement (i.e., moves radially outward along the first guide groove 471) to cause multiple sets of filter plates 15 to open and form a filter barrel. When the rotary drive mechanism drives the drive disk 46 to rotate in the reverse direction, the drive disk 46 drives multiple sets of second hinge shafts 34 to move radially inward. Similarly, in order to adapt to this deformation from the filter barrel to the stirring blades, the first hinge shaft 33 also undergoes an adaptive movement (i.e., moves radially inward along the first guide groove 471) to cause multiple sets of filter plates 15 to fold and form stirring blades. Furthermore, as the rotary drive mechanism continues to move in the reverse direction, it can drive the stirring blades to rotate to achieve the stirring function.

[0125] See Figures 11-28 In this embodiment, the water extraction device 7 further includes a lifting scraping mechanism for scraping filter residue on the outer surface of the filter plate 15 in filtration mode; the lifting scraping mechanism includes a mounting frame 13, multiple sets of scrapers 14 disposed on the mounting frame 13, and a lifting drive mechanism for driving the mounting frame 13 to perform vertical reciprocating motion, wherein...

[0126] The mounting frame 13 is located outside the filter stirring mechanism and is coaxially arranged with the filter stirring mechanism; the number of scrapers 14 is the same as the number of sides of the filter stirring mechanism when it is unfolded into a filter bucket, and they correspond one-to-one. For example, if the filter stirring mechanism unfolds into a filter bucket with a hexagonal structure, then the scrapers 14 are also set to six groups, and each group of scrapers 14 is used to scrape off the filter residue on one side of the hexagonal filter bucket.

[0127] The lifting drive mechanism is used to drive the mounting frame 13 to perform vertical reciprocating motion. The lifting drive mechanism includes a fixed frame 8 mounted on the guide plate 47, a lifting frame 48 mounted on the fixed frame 8, a screw transmission mechanism, and a lifting power mechanism for driving the screw transmission mechanism. The screw transmission mechanism includes a vertically arranged bidirectional screw 9 and a screw nut mounted on the bidirectional screw 9. Both the upper and lower ends of the bidirectional screw 9 are rotatably connected to the fixed frame 8. The screw nut is mounted on the lifting frame 48. The lifting frame 48 and the mounting frame 13 are connected by multiple sets of vertically arranged connecting shafts 11. The upper end of the connecting shaft 11 is mounted on the lifting frame 48, and the lower end passes through the guide plate 47 and is mounted on the mounting frame 13. The guide plate 47 is provided with guide holes that cooperate with the connecting shafts 11.

[0128] The lifting power mechanism drives the bidirectional lead screw 9 to rotate, thereby causing the lead screw nut and the lifting frame 48 mounted on the lead screw nut to rise and fall. This, in turn, causes the scraper 14 to scrape the filter residue on the outer surface of the filter plate 15. The advantage of this configuration is that:

[0129] (1) During the filtration process, the filter residue on the outer surface of the filter plate 15 can be removed, thereby ensuring that the outer side of the filter hole will not be blocked, thus ensuring the smooth progress of filtration and improving the filtration efficiency.

[0130] (2) After the water extract from the Alpinia oxyphylla powder is extracted, the filtration and stirring mechanism can first maintain the filter bucket state, and then the cleaning spray mechanism on the inner wall of the stirring tank 42 sprays high-pressure water to clean the outer surface of the filter plate 15. At the same time, the lifting drive mechanism drives the mounting frame 13 and the scraper 14 installed on the mounting frame 13 to rise and fall, thereby cooperating with the cleaning spray mechanism to quickly remove the filter residue on the outer surface of the filter bucket.

Similarly, the upper end of the second rotating shaft 27 can also extend into the inner cavity of the first rotating shaft 10, and the outer wall of the second rotating shaft 27... The inner walls of the first rotating shaft 10 are connected by bearings 40, which also allows the first rotating shaft 10 and the second rotating shaft 27 to rotate relative to each other; the drive disk 46 is connected to the second rotating shaft 27 by bearings 40, allowing the drive disk 46 and the second rotating shaft 27 to rotate relative to each other; an upper drive wheel 21 is installed at the lower end of the first rotating shaft 10, and a bearing 40 is provided between the mounting hole of the upper drive wheel 21 and the first rotating shaft 10, and the upper drive wheel 21 is an upper drive gear; a lower drive wheel 24 is installed at the upper end of the second rotating shaft 27, and the lower drive wheel 24 is fixedly installed on the second rotating shaft 27;

[0134] The forward rotation drive mechanism includes a support frame 12 mounted on the guide plate 47, a rotating shaft 18 mounted on the support frame 12, and an upper transmission gear 17 and a lower transmission gear 20 mounted on the upper and lower sides of the rotating shaft 18. Both ends of the rotating shaft 18 are rotatably connected to the support frame 12, and a torsion spring 16 is provided between the rotating shaft 18 and the support frame 12. The upper transmission gear 17 is mounted on the upper end of the rotating shaft 18 and meshes with the upper drive gear; the upper transmission gear 17 is an incomplete gear. The lower transmission gear 20 is mounted on the lower end of the rotating shaft 18. A drive gear 35 meshing with the lower transmission gear 20 is provided at the rotating part of the drive plate 46.

[0135] The reversing drive mechanism includes a connector, the upper end of which is fixedly connected to the lower end of the lower drive wheel 24, and the lower end of which is connected to the guide disk 47; in this embodiment, the lower end of the second rotating shaft 27 is fixedly connected to the guide disk 47, thereby forming the connector;

[0136] The reversing mechanism is used to transmit power from the first rotating shaft 10 to the upper drive wheel 21 or the lower drive wheel 24. The reversing mechanism includes a drive wheel 23 and a drive element 41.

[0137] The active drive wheel 23 is fixed to the lower end of the first rotating shaft 10 and is located between the upper drive wheel 21 and the lower drive wheel 24; the lower side of the upper drive wheel 21 and the upper side of the lower drive wheel 24 are both provided with inclined grooves 39, and there are multiple sets of inclined grooves 39. The multiple sets of inclined grooves 39 are arranged at equal intervals along the circumferential direction of the upper drive wheel 21 and the lower drive wheel 24, wherein the inclination directions of the inclined grooves 39 in the upper drive wheel 21 and the lower drive wheel 24 are opposite.

[0138] The driving components 41 are in two sets, respectively mounted on the upper and lower sides of the drive wheel 23; the driving component 41 on the upper side is the upper driving component, and the driving component 41 on the lower side is the lower driving component; each set of driving components 41 includes a mounting base 411 and a pawl 412 disposed on the mounting base 411, wherein the drive wheel 23 is provided with a groove for mounting the mounting base 411; the pawl 412 is rotatably connected to the mounting base 411, and the pawl 412 is provided with an inclined portion and a driving portion. Figure 20 The arrow in the figure indicates the swing direction of the paddle 412; a return torsion spring is provided between the mounting base 411 and the paddle 412, and the elastic force of the return torsion spring is used to cause the paddle 412 to extend into the inclined groove 39 in the corresponding drive wheel; the inclined directions of the inclined portions of the paddle 412 in the upper drive member and the lower drive member are opposite.

[0139] When the active drive wheel 23 rotates in the forward direction, the driving part of the tooth 412 in the upper drive member engages with the inclined groove 39 in the upper drive wheel 21 to drive the upper drive wheel 21 to rotate; the inclined part of the tooth 412 in the lower drive member engages with the inclined groove 39 in the lower drive wheel 24 to cause the tooth 412 in the lower drive member to overcome the elastic force of the return torsion spring and disengage from the inclined groove 39 in the lower drive wheel 24 when the active drive wheel 23 rotates in the forward direction, that is, the lower drive wheel 24 does not rotate; When the active drive wheel 23 rotates in the reverse direction, the driving part of the tooth 412 in the lower drive member engages with the inclined groove 39 in the lower drive wheel 24 to drive the lower drive wheel 24 to rotate; the inclined part of the tooth 412 in the upper drive member engages with the inclined groove 39 in the upper drive wheel 21 to cause the tooth 412 in the upper drive member to overcome the elastic force of the return torsion spring and disengage from the inclined groove 39 in the upper drive wheel 21 when the active drive wheel 23 rotates in the reverse direction, that is, the upper drive wheel 21 does not rotate;

[0140] The lifting power mechanism includes a driven gear 22 disposed at the lower end of the bidirectional lead screw 9 and meshing with the upper drive gear; the driven gear 22 is fixedly connected to the optical shaft portion of the bidirectional lead screw 9.

[0141] With the above configuration, the working principle of the rotary drive mechanism and the lifting drive mechanism in this invention is as follows:

[0142] When the filtration and stirring mechanism switches to filtration mode, that is, changes from the state of stirring fan blades to the state of filter barrel, the specific steps are as follows:

[0143] The servo motor 44 drives the first rotating shaft 10 to rotate in the forward direction (taking clockwise rotation as an example), and the active drive wheel 23 also rotates in the forward direction. The driving part of the tooth 412 in the upper drive member engages with the inclined groove 39 in the upper drive wheel 21 to drive the upper drive wheel 21 to rotate. The inclined part of the tooth 412 in the lower drive member engages with the inclined groove 39 in the lower drive wheel 24, so that when the active drive wheel 23 rotates in the forward direction, the tooth 412 in the lower drive member overcomes the elastic force of the return torsion spring and disengages from the inclined groove 39 in the lower drive wheel 24, that is, the lower drive wheel 24 does not rotate. The forward rotation of the upper drive wheel 21 will drive the upper transmission meshed with it. Gear 17 and driven gear 22 rotate, wherein the rotation of driven gear 22 drives the bidirectional lead screw 9 to rotate, thereby driving the lifting frame 48 and the mounting frame 13 installed in the lifting frame 48 and the scraper 14 inside the mounting frame 13 to perform lifting and reciprocating motion; while the rotation of upper transmission gear 17 drives the rotating shaft 18 to rotate against the elastic force of torsion spring 16, thereby driving the lower transmission gear 20 to rotate, and the rotation of lower transmission gear 20 drives the drive gear 35 installed on the drive disk 46 to rotate, thereby driving the drive disk 46 to rotate in the forward direction, thereby driving multiple sets of second hinge shafts 34 to move radially outward, so that the filter stirring mechanism is deformed into a filter bucket;

[0144] In the above process, since the upper transmission gear 17 is an incomplete gear, that is, the teeth in the upper transmission gear 17 are not continuous and there are areas without teeth, this area is defined as the non-meshing area. By controlling the design dimensions between each component, when the incomplete gear rotates to the non-meshing area, the second hinge shaft 34 and the first hinge shaft 33 both move radially outward to the outermost side. At this time, since the upper drive gear is in contact with the non-meshing area in the upper transmission gear 17, the upper drive gear will not be able to drive the upper transmission gear 17 to continue rotating. Therefore, the upper drive gear can only drive the driven gear 22 to rotate, thereby driving the scraper 14 to move vertically reciprocating. At this time, the filtering and stirring mechanism remains in the state of the filter bucket to filter the soaked mixture. Since the outlet 422 is located at the middle position of the bottom of the filter bucket, the valve at the outlet 422 can be opened to pump the filtrate that has been filtered inside the filter bucket to the next processing station.

[0145] After the mixture is completely removed and the internal filter residue is cleaned, the filtration and stirring mechanism switches back to stirring mode, transforming into a stirring fan blade. The specific steps are as follows:

[0146] The servo motor 44 drives the first rotating shaft 10 to rotate in the opposite direction (taking counterclockwise rotation as an example). The active drive wheel 23 also rotates in the opposite direction. The driving part of the tooth 412 in the lower drive member cooperates with the inclined groove 39 in the lower drive wheel 24 to drive the lower drive wheel 24 to rotate. The inclined part of the tooth 412 in the upper drive member cooperates with the inclined groove 39 in the upper drive wheel 21 to cause the tooth 412 in the upper drive member to overcome the elastic force of the reset torsion spring and disengage from the inclined groove 39 in the upper drive wheel 21 when the active drive wheel 23 rotates in the opposite direction. That is, the upper drive wheel 21 does not rotate. Since the upper drive wheel 21 and the first rotating shaft 10 are not fixedly connected, but connected through a bearing, the "bearing connection" means that the outer ring of the bearing is engaged with the inner hole of the upper drive wheel 21, and the inner ring is engaged with the first shaft 10. The rotating shaft 10 is engaged, allowing the upper drive wheel 21 to rotate relative to the first rotating shaft 10. Based on the above structure, since the upper drive wheel 21 (i.e., the upper drive gear) has no active rotation power, under the elastic force of the torsion spring 16, the rotating shaft 18 will rotate in the opposite direction (relative to the previous forward rotation of the rotating shaft 18), thereby driving the lower transmission gear 20 to rotate in the opposite direction, which in turn drives the drive gear 35 mounted on the drive disk 46 to rotate in the opposite direction. The reverse rotation of the drive disk 46 causes the second hinge shaft 34 to move radially inward. Correspondingly, the first hinge shaft 33 will also move radially inward, thereby causing the filter stirring mechanism to switch to the stirring state, i.e., transform into a stirring fan blade (this switching process can also be achieved by stopping the forward rotation of the first rotating shaft 10, for example, by de-energizing the servo motor 44).

[0147] During the above process, since the servo motor 44 drives the first rotating shaft 10 to rotate in the opposite direction, the active drive wheel 23 will drive the lower drive wheel 24 to rotate in the opposite direction, thereby driving the second rotating shaft 27 and the guide disk 47 installed on the second rotating shaft 27 to rotate, and then driving the lifting scraping mechanism to rotate synchronously. The purpose of this setting is to ensure that the scraper 14 in the lifting scraping mechanism can correspond one-to-one with each side of the filter bucket, thereby ensuring that the lifting scraping mechanism can work normally.

[0148] See Figures 11-28 The filtering and stirring mechanism further includes a blocking drive mechanism for opening or closing the filter holes on the filter plate 15; the blocking drive mechanism includes a blocking plate 37 and a vertical drive mechanism for driving the blocking plate 37 to move vertically, wherein,

[0149] The sealing plate 37 is slidably connected to the inner side of the filter plate 15, and the sealing plate 37 is provided with through holes that correspond one-to-one with the filter holes.

[0150] The vertical drive mechanism includes a support 25, a pull rod 28 mounted on the support 25, and a swing arm 26 for driving the pull rod 28 to move vertically. The support 25 is fixed to the second rotating shaft 27 and is located outside the second rotating shaft 27. The lower end of the pull rod 28 is connected to the sealing plate 37 in each filter plate 15 through a connecting structure, and the upper end extends vertically upward from the center of the second rotating shaft 27. The side of the second rotating shaft 27 is provided with a notch. The middle part of the swing arm 26 is hinged to the support 25, one end (connecting end) extends into the interior of the second rotating shaft 27 and is hinged to the upper end of the pull rod 28; the other end (swinging end) is located outside the second rotating shaft 27.

[0151] The rotating shaft 18 is provided with a swing drive mechanism for driving the swing arm 26 to swing. The swing drive mechanism includes a rotating wheel 19 on the rotating shaft 18 and a spiral groove 191 on the outside of the rotating wheel 19. The swing end of the swing arm 26 is provided with a ball bearing 261 that cooperates with the spiral groove 191. When the reversing mechanism transmits the power of the servo motor 44 to the upper drive wheel 21, the rotating wheel 19 rotates synchronously with the upper transmission gear 17, driving the swing arm 26 to swing to open the filter hole.

[0152] In this embodiment, the connection structure includes a tension rope 31 and a fastener for mounting the tension rope 31, wherein,

[0153] One end of the tension rope 31 is installed on the sealing plate 37, and the other end is connected to the fixing member;

[0154] The fastener includes a locking sleeve 29 and a fixing sleeve 30 disposed inside the locking sleeve 29. The fixing sleeve 30 is provided with locking grooves, and there are multiple sets of locking grooves, which are evenly arranged along the circumference of the fixing sleeve 30. The other end of the tension rope 31 is located in the locking groove. The locking sleeve 29 cooperates with the fixing sleeve 30 to fix the other end of the tension rope 31.

[0155] The lower end of the pull rod 28 passes through the inside of the fixed sleeve 30 and is connected to the limiting block 32. A compression spring 36 is provided on the pull rod 28. The compression spring 36 is sleeved on the pull rod 28. The upper end of the compression spring 36 acts on the fixed sleeve 30, and the lower end acts on the limiting block 32. The elastic force of the compression spring 36 causes the pull rod 28 to move downward.

[0156] With the above configuration, the working principle of the blocking drive mechanism is as follows:

[0157] When the upper drive wheel 21 drives the upper transmission gear 17 to rotate, that is, when the filter stirring mechanism is switched to filter barrel, the filter hole is opened; when the filter stirring mechanism is switched to stirring fan blade, the filter hole is closed. The rotating shaft 18 drives the rotating wheel 19 to rotate. The spiral groove 191 on the rotating wheel 19 causes the swing end of the swing arm 26 to move vertically, thereby driving the pull rod 28 to move vertically. The vertical movement of the pull rod 28 will drive the fixing part to move vertically, thereby driving the sealing plate 37 on each filter plate 15 to move vertically through each tension rope 31, thereby opening or closing the filter hole on the filter plate 15.

[0158] In the above process, the movement distance of the sealing plate 37 can be limited by the sliding structure. Since the rotating wheel 19 is mounted on the rotating shaft 18, in order to prevent the rotating shaft 18 from continuing to rotate when the ball bearing 261 on the swing end of the swing arm 26 moves to the end of the spiral groove 191 on the rotating wheel 19, a friction plate can be provided between the rotating wheel 19 and the rotating shaft 18. When the force exerted on the rotating wheel 19 by the swing arm 26 is greater than the friction force between the rotating wheel 19 and the friction plate, the rotating wheel 19 and the rotating shaft 18 can rotate relative to each other, thereby avoiding interference with the rotation of the rotating shaft 18. This can also greatly reduce the machining accuracy and assembly accuracy of the parts.

[0159] When the spring force of the torsion spring 16 causes the rotating shaft 18 to rotate in the opposite direction, the rotating wheel 19 also rotates in the opposite direction, causing the swing arm 26 to swing in the opposite direction again under the pressure of the compression spring 36 and the guidance of the spiral groove 191, thereby driving the pull rod 28 to move in the opposite direction, thereby causing the sealing plate 37 to block the filter hole of the filter plate 15 again.

[0160] In addition, when the filter stirring mechanism switches to the filter mode, that is, when it becomes a filter barrel, the distance between the axis of each filter plate 15 and the filter barrel changes. Therefore, the relative movement between the fixing member and the limiting block 32 of the pull rod 28 will occur, causing the compression spring 36 to be compressed, thereby avoiding the tension rope 31 from interfering with the switching of the filter stirring mechanism.

[0161] See Figures 11-28 The mixing tank 42 is provided with a partition 45, which is located above or below the guide plate 47. The partition 45 is used to divide the internal space of the mixing tank 42 into two spaces, an upper space and a lower space. The upper space is used to install the transmission components, while the lower space is used to soak, stir and filter the Alpinia oxyphylla powder. At the same time, the transmission components in the upper space can be sealed and waterproofed without affecting its function.

[0162] See Figures 11-28 The feed inlet 421 of the mixing tank 42 is located on the upper side of the mixing tank 42, and the feed inlet 421 is connected to the lower space through the conveying pipe 43; the partition plate 45 is provided with a clearance groove.

[0163] See Figures 11-28 The mixing tank 42 is equipped with a temperature control device and a water level control device. The temperature control device includes a temperature sensor and a heating module. The temperature sensor detects the temperature of the extract, and the heating module heats the extract to maintain the temperature of the extract in the mixing tank 42 within the most suitable extraction temperature range. The water level control device includes a liquid level sensor, which is used to detect the liquid level height in the mixing tank 42.

[0164] See Figures 11-28 The valves at the liquid inlet, feed inlet 421, liquid outlet 422 and discharge outlet 423 can all be controlled by solenoid valves, and necessary waterproofing measures should be taken.

[0165] See Figures 11-28 The inner wall of the mixing tank 42 is provided with a cleaning spray mechanism. After the filtrate is completely pumped to the next processing station, the cleaning spray mechanism sprays high-pressure water to clean the outer wall of the filter tank. At the same time, the lifting drive mechanism drives the scraper 14 to move vertically back and forth to clean the filter residue remaining on the outside of the filter plate 15.

[0166] In this embodiment, the cleaning spray mechanism can use nozzles, and there are multiple sets of nozzles arranged in the circumferential and height directions of the mixing tank 42, which work in conjunction with the lifting and scraping mechanism to clean the filter residue on the outer wall of the filter barrel.

[0167] In addition, the position and spray angle of the nozzle can be adjusted, and the nozzle can also be a fan-shaped nozzle; the discharge port 423 is located on the outside of the filter barrel.

[0168] See Figure 29The bottom of the mixing tank 42 is provided with a rotating disk 38, which is rotatably connected to the bottom of the mixing tank 42. The center of the rotating disk 38 is hollowed out to avoid the liquid outlet 422. The rotating disk 38 is provided with a third guide groove 381 and a fourth guide groove 382. There are multiple sets of third guide grooves 381, which correspond one-to-one with the first guide groove 471. There are multiple sets of fourth guide grooves 382, ​​which correspond one-to-one with the second guide groove 472. The lower end of the first hinge shaft 33 is located in the third guide groove 381. The lower end of the second hinge shaft 34 is located in the fourth guide groove 382. Both the third guide groove 381 and the fourth guide groove 382 are open grooves, that is, the outer side is open. The third guide groove 381 and the fourth guide groove 382 extend radially to the edge of the rotating disk 38.

[0169] With the above configuration, since the function switching mechanism acts on the upper end of the first hinge shaft 33 and the second hinge shaft 34 during the switching between the filtering and stirring modes, in order to prevent the bottom of the filter plate 15 from deforming during radial movement or to ensure that both the upper and lower sides of the filter plate 15 can move synchronously, a rotating disk 38 is provided at the bottom of the stirring tank 42, and a third guide groove 381 and a fourth guide groove 382 are provided on the rotating disk 38, which correspond one-to-one with the first guide groove 471 and the second guide groove 472 in the guide disk 47. This can achieve synchronous guidance of the upper and lower ends of the first hinge shaft 33 and the second hinge shaft 34, and the rotating disk 38 and the guide disk 47 rotate synchronously.

[0170] In addition, the outer sides of the third guide groove 381 and the fourth guide groove 382 are open, which can prevent filter residue from accumulating in the third guide groove 381 and the fourth guide groove 382. Even if filter residue accumulates in the third guide groove 381 and the fourth guide groove 382, ​​it is only located on the outer side of the filter plate 15. When the filter stirring mechanism is transformed into a filter barrel, the first hinge shaft 33 and the second hinge shaft 34 move radially outward in the third guide groove 381 and the fourth guide groove 382 respectively, thereby pushing the filter residue in the third guide groove 381 and the fourth guide groove 382 out of the third guide groove 381 and the fourth guide groove 382 respectively.

[0171] Example 5

[0172] The difference between this embodiment and embodiment 4 is that:

[0173] The lead screw nut adopts a split structure, namely, it consists of a first lead screw nut and a second lead screw nut. An electromagnetic clutch is provided on the lifting frame 48. The electromagnetic clutch is used to drive the first lead screw nut and the second lead screw nut to tighten or loosen the bidirectional lead screw 9. A spring is provided between the lifting frame 48 and the guide plate 47. The spring can be sleeved on the connecting shaft 11 or on the bidirectional lead screw 9. The elastic force of the spring causes the lifting frame 48 to move upward, so as to cause the mounting frame 13 and the scraper 14 on the mounting frame 13 to return to the initial position / height.

[0174] When the filter stirring mechanism switches to the filter mode, the electromagnetic clutch drives the first lead screw nut and the second lead screw nut to grip the bidirectional lead screw 9, thereby causing the lifting frame 48 to move up and down against the elastic force of the spring.

[0175] When the filter stirring mechanism switches to the stirring mode, the electromagnetic clutch drives the first lead screw nut and the second lead screw nut to release the bidirectional lead screw 9, so that the lifting frame 48 moves upward under the elastic force of the spring, so as to cause the mounting frame 13 and the scraper 14 on the mounting frame 13 to return to the initial position / height.

[0176] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.

The fully automated processing line for water extract of Alpinia oxyphylla according to claim 5, characterized in that, The detection device further includes a visual positioning module for detecting the position information of the Alpinia oxyphylla in the container; the visual positioning module is mounted on the bracket and is used to detect the Alpinia oxyphylla that arrives at the rejection station to obtain the position information of the Alpinia oxyphylla in the container; the bottom of the container has multiple sets of air holes, which are divided into a first air hole located at the center of the container and a second air hole located around the first air hole, wherein the axis of the first air hole passes through the center of the container; the second air holes are inclined, and the extension lines of the axes of all the second air holes intersect at the same convergence point, and the convergence point is located on the extension line of the axis of the first air hole; correspondingly, the nozzle is provided with a first air outlet and a second air outlet at the corresponding positions of the first air hole and the second air hole, respectively, wherein the first air outlet and the second air outlet can be controlled independently; When the cardamom pods are transported to the rejection station along with the container, the vision positioning module triggers the acquisition of real-time image information of the cardamom pods to be rejected and uploads it to the control system. The control system extracts and analyzes the features of the real-time image information, calculates the center of gravity position of the cardamom pods to be rejected, and performs a difference calculation between the center of gravity position and the preset center position of the container. If the deviation exceeds the allowable range, the control system generates a position correction signal, matches the corresponding nozzle according to the deviation direction and deviation amount, drives one or more sets of second air blowing ports in the nozzle to open and blow out directional airflow, correcting the position of the cardamom pods in the container through airflow thrust. After the position correction is completed, the control system, based on the pre-generated rejection control signal, drives the first air blowing port in the nozzle to start and output rejection airflow, accurately rejecting the unqualified cardamom pods from the container.

7. The fully automated processing line for water extract of Alpinia oxyphylla according to claim 6, characterized in that, A pressure sensor is installed at the bottom of the container; the pressure sensor is used to detect the weight of the Alpinia oxyphylla entering the container in real time and transmit the weight information to the control system; the control system has a built-in air pressure calculation model, which calculates the nozzle blowing force value and suction force value matching the weight information of the Alpinia oxyphylla to be removed, and integrates the blowing force control parameters and suction force control parameters into the removal control signal to adjust the air pressure of the nozzle and the suction pressure of the suction nozzle, so as to achieve accurate removal of unqualified Alpinia oxyphylla.

9. A production method for the fully automated processing line for the aqueous extract of Alpinia oxyphylla as described in any one of claims 1-8, characterized in that, Includes the following steps: Step 1: The feeding device delivers Alpinia oxyphylla kernels into the containers located at the feeding station, and each container can only hold one Alpinia oxyphylla kernel. Step 2: The conveyor drive mechanism moves the conveyor belt and the container set on the conveyor belt to the testing station. The testing device detects the aflatoxin content, heavy metal content, microbial content, and active ingredient content of the Alpinia oxyphylla at the testing station and sends the test results to the control system. The control system determines whether the quality of the Alpinia oxyphylla in the corresponding container meets the preset quality standard based on the test results. When it is determined that the quality of the Alpinia oxyphylla does not meet the preset quality standard, the control system generates and outputs a rejection control signal to the rejection device. Step 3: When the conveyor belt carries the Alpinia oxyphylla to the rejection station, the rejection device rejects the unqualified Alpinia oxyphylla in the container according to the rejection control signal. Step 4: After removing the unqualified Alpinia oxyphylla, the conveyor belt continues to carry the Alpinia oxyphylla to the crushing station, where it is crushed by the crushing device to obtain crushed Alpinia oxyphylla powder; the powder is then quantitatively transported to the water extractor via the conveying module. Step 5: Add the extractant to the water extractor and extract the water extract from Alpinia oxyphylla by controlling the extraction time and temperature to obtain a crude water extract of Alpinia oxyphylla. Step 6: The obtained crude aqueous extract of Alpinia oxyphylla is transported to subsequent purification equipment, vacuum concentration equipment, spray drying equipment and automatic packaging equipment to complete the purification, concentration, drying and packaging processes in sequence, and finally obtain the finished product of Alpinia oxyphylla aqueous extract.

10. The production method according to claim 9, characterized in that, In step 2, the rules for judging the quality of Alpinia oxyphylla are as follows: If any one of the following in the Alpinia oxyphylla content—aflatoxin content, heavy metal content, microbial content, or active ingredient content—does not meet the preset quality standard, then the Alpinia oxyphylla is determined to be a substandard product. When the aflatoxin content, heavy metal content, microbial content, and active ingredient content in the Alpinia oxyphylla all meet the preset quality standards, the aflatoxin content, heavy metal content, microbial content, and active ingredient content are input into the AI ​​quality recognition model trained in the control system to obtain the predicted water extract yield. The control system compares the predicted water extract yield with a preset threshold: if the predicted water extract yield is greater than or equal to the preset threshold, the Alpinia oxyphylla is determined to be a qualified product and is allowed to enter the subsequent processing stage; if the predicted water extract yield is less than the preset threshold, the Alpinia oxyphylla is determined to be a non-qualified product.
