Description

Technical Field

[0001] This invention relates to the field of closed fruit drying detection technology, specifically to an intelligent closed fruit drying component detection device, and more particularly to a device suitable for accurately extracting and detecting the diffuse gas components after drying in the intelligent drying process of closed fruits such as walnuts, hazelnuts, and almonds. Background Technology

[0002] During the drying process of closed fruits (such as walnuts, hazelnuts, and almonds), the internal moisture and volatile components gradually diffuse into the surrounding environment after being heated. By detecting the content of specific components in these diffused gases, the degree of drying and quality status of the closed fruits can be accurately determined, thereby achieving precise control over the drying process. Infrared spectroscopy, due to its advantages such as non-destructive nature, simultaneous detection of multiple components, and fast response speed, has been widely used in the qualitative and quantitative analysis of gas components.

[0003] However, during the drying process of closed fruits, because the closed fruits are piled up on the supporting device, the volatile gas components generated after drying are mainly concentrated in a small space near the surface of the closed fruits, and their dispersion range is extremely limited. Traditional gas extraction detection methods usually employ large-scale or long-distance extraction, that is, extracting the gas throughout the entire drying chamber through extraction pipes installed on the top or side walls of the drying chamber. This extraction method has the following significant drawbacks:

[0004] First, an excessively large suction range leads to significant dilution of the gas being tested by air, resulting in a much lower concentration of the target component detected by the infrared spectrometer compared to the actual concentration in the diffused gas, severely impacting detection accuracy and sensitivity. Second, long-distance suction requires lengthy extraction pipelines, and gas is prone to condensation and adsorption losses during transport, further reducing detection accuracy. Third, large-scale suction cannot achieve precise sampling at specific points or locations, making it difficult to distinguish the differences in drying status between different regions or batches of closed fruits. Fourth, the fixed suction port position of traditional suction devices cannot be adaptively adjusted according to the position of the supporting components and the stacking height of closed fruits, resulting in a large distance between the suction port and the gas diffusion area, leading to low suction efficiency.

[0005] While some extendable suction devices exist in existing technologies, these devices are mostly used in fields such as range hoods and medical devices. Their telescopic structure and driving method are not suitable for the specific requirements of closed-fruit drying detection scenarios, such as precise docking and synchronous extension and retraction of the suction tube and support components, as well as the sealing and connection of the air passage. Therefore, there is an urgent need for a detection device that can accurately and closely suction the diffused gas after the closed-fruit has dried, in order to solve the technical problems of the large suction range and inaccuracy of traditional suction methods. Summary of the Invention

[0006] To address the technical problems of large suction range, inaccurate sampling, and low detection sensitivity in existing gas component detection methods during closed-fruit drying, this invention provides an intelligent closed-fruit drying component detection device that can achieve precise docking of the suction tube and the support component and close-range suction, effectively improving the accuracy and sensitivity of gas component detection.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A smart drying component detection device for closed fruits is installed inside a smart detection and drying chamber and connected to a gas component infrared spectrometer. The smart detection and drying chamber is equipped with an infrared drying system. The device includes: a support component for arranging the closed fruits to be tested; a conveying component for transporting the support component; and a suction component for facilitating the extraction of the component mixture gas dispersed in the gas after the closed fruits on the support component have been dried by the gas component infrared spectrometer.

[0009] The conveying assembly is installed inside the intelligent detection and drying chamber, and the suction-guiding assembly is installed on top of the detection and drying chamber and directly opposite the conveying assembly. The supporting assembly is conveyed by the conveying assembly to the area below the suction-guiding assembly to complete the suction of the dried mixed gas, and then sent out of the detection and drying chamber after detection. The supporting assembly includes a support tray and a central tube, with the central tube installed at the center of the support tray, and the suction-guiding assembly able to connect and communicate with the central tube.

[0010] As a further improvement of the present invention, the suction assembly includes a fixed frame, a suction tube, a tube telescopic mechanism, and a transmission mechanism for driving the tube telescopic mechanism. The fixed frame is fixedly installed on the top of the detection and drying chamber, the suction tube is slidably installed inside the tube telescopic mechanism, the tube telescopic mechanism is installed at one end of the transmission mechanism, and the transmission mechanism is installed on the fixed frame and driven by a drive mechanism. Driven by the tube telescopic mechanism, the suction tube can closely adhere to the supporting assembly to suction the mixed gas. The suction tube communicates with the transmission mechanism and the tube telescopic mechanism, and a suction port is opened on the side wall of the air inlet end of the suction tube. A sensor module is installed at the end near the suction port.

[0011] As a further improvement of the present invention, the catheter telescopic mechanism includes: an inner connecting sleeve, an outer connecting sleeve, and a telescopic sleeve. The inner connecting sleeve is mounted on the transmission mechanism, the telescopic sleeve is rotatably mounted on the outside of the inner connecting sleeve, the suction tube is rotatably mounted on the inside of the inner connecting sleeve, the outer connecting sleeve is sleeved on the outside of the telescopic sleeve, and the outer connecting sleeve is fixedly connected to the transmission mechanism and driven by the transmission mechanism to slide along the length direction of the telescopic sleeve.

[0012] As a further improvement of the present invention, the inner side of the telescopic sleeve is provided with a forward spiral groove, and the outer side is provided with a reverse spiral groove. The suction tube is slidably connected to the forward spiral groove on the inner side of the telescopic sleeve via a guide post, and the guide post is fixed to the outer end of the suction tube away from the suction port. The outer connecting sleeve is slidably connected to the reverse spiral groove on the outer side of the telescopic sleeve via a guide block, and the guide block is fixedly disposed in the middle of the inner side of the outer connecting sleeve.

[0013] As a further improvement of the present invention, the inner connecting sleeve is provided with a constraint guide groove that constrains the suction tube to move linearly along its length direction. The guide post of the suction tube is slidably connected to the constraint guide groove, and the telescopic sleeve is rotatably connected to the inner connecting sleeve through a retaining ring and a retaining groove.

[0014] As a further improvement of the present invention, the transmission mechanism includes: a transmission shaft connected to the drive mechanism, a guide rail assembly, and a guide cam. The transmission shaft is rotatably mounted on a fixed base, and the guide cam is fixed to the fixed base and sleeved on the outside of the transmission shaft. The guide rail assembly and the guide cam are slidably connected through cam grooves, the guide rail assembly is mounted on the transmission shaft through a bushing, and the guide rail assembly is fixedly connected to the outer connecting sleeve. The transmission shaft has a hollow structure, one end of which is connected to the inner connecting sleeve, and the other end is connected to the air inlet pipe of the infrared spectrometer through a rotary joint.

[0015] As a further improvement of the present invention, the guide rail assembly includes guide rail one and guide rail two. Guide rail one and guide rail two are symmetrically mounted on the bushing through a guide seat. One end of guide rail one and guide rail two are slidably connected to the cam groove of the guide cam through a stop wheel.

[0016] As a further improvement of the present invention, the other end of the first guide rail is fixedly connected to the outer connecting sleeve, and the other end of the second guide rail is equipped with a docking sleeve, which can dock with the central tube of the supporting component.

[0017] As a further improvement of the present invention, when the guide rail drives the outer connecting sleeve to move up and down along the length direction of the telescopic sleeve, the guide block of the outer connecting sleeve cooperates with the reverse spiral groove of the telescopic sleeve to drive the telescopic sleeve to rotate, and the forward spiral groove on the inner side of the telescopic sleeve slides with the guide post of the suction tube, driving the suction tube to extend and retract up and down along the constraint guide groove on the inner connecting sleeve.

[0018] As a further improvement of the present invention, when the guide rail II moves up and down, it drives the docking sleeve and the suction tube to extend and retract synchronously, and the docking sleeve is preferentially connected to the center tube before the suction tube.

[0019] As a further improvement of the present invention, the sensor module includes a temperature sensor, which is used to detect the drying temperature inside the tray and control the drive mechanism to start after a preset time when the drying temperature is reached.

[0020] As a further improvement of the present invention, after the conveying component conveys the supporting component to the bottom of the suction component, the supporting component is aligned with the suction component by centering positioning.

[0021] Beneficial effects

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] Precise close-range suction: This invention, through the setting of a suction guide component 300, allows the suction tube 320, driven by the guide tube telescopic mechanism 330, to directly extend into the central tube 120 of the support tray 110, making the suction port 321 close to the gas diffusion area on the surface of the closed fruit to be tested. Compared with traditional large-area suction methods, the suction range of this invention is significantly reduced, the target gas components are not diluted by a large amount of air, effectively improving the concentration of the target components detected by the infrared spectrometer, and significantly improving detection accuracy and sensitivity.

[0024] Precise docking of the suction tube and the support assembly: This invention achieves the synchronous telescopic movement of the suction tube 320 and the docking sleeve 349 through the staggered vertical movement of guide rail 1 3421 and guide rail 2 3422 in the guide rail assembly 342. Moreover, the docking sleeve 349 is aligned and connected to the central tube 120 before the suction tube 320, ensuring that the air passage is sealed and docked before the suction tube 320 extends into the central tube 120, avoiding gas leakage, and ensuring the reliability of suction and the accuracy of detection results.

[0025] Bidirectional spiral groove differential transmission design: This invention features a forward spiral groove 3331 and a reverse spiral groove 3332 on the inner and outer sides of the telescopic sleeve 333, respectively. These, in conjunction with the guide post 323 of the suction tube 320 and the guide block 3321 of the outer connecting sleeve 332, achieve a two-stage motion conversion: linear motion of the outer connecting sleeve 332, rotational motion of the telescopic sleeve 333, and then linear motion of the suction tube 320. This design enables a large-stroke telescopic movement of the suction tube 320 within a limited space, resulting in a compact structure and high transmission efficiency.

[0026] Integrated gas path design: The drive shaft 341 of this invention has a hollow structure, with one end connected to the inner connecting sleeve 331 and the other end connected to the air inlet pipe of the infrared spectrometer via a rotary joint 346. The guide tube 320 is connected to the drive mechanism 340 and the guide tube telescopic mechanism 330, which makes the suction airflow path short and the sealing good, avoiding condensation and adsorption loss of gas during long-distance transportation, and further ensuring the accuracy of detection.

[0027] Intelligent control: By setting a sensor module 322 (including a temperature sensor) at the end of the suction tube 320, the present invention can automatically control the drive mechanism to start after a preset time when the drying temperature is reached, so as to realize the automatic extension and suction detection of the suction tube 320 without manual intervention, thereby improving the automation level and efficiency of detection.

Detailed Implementation

[0037] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0038] Example 1

[0039] like Figures 1 to 8 As shown, this invention provides an intelligent drying component detection device for closed fruits, which is installed inside an intelligent detection and drying chamber and connected to a gas component infrared spectrometer. The intelligent detection and drying chamber is equipped with an infrared drying system for heating and drying the closed fruits to be tested.

[0040] The device includes a support assembly 100, a conveying assembly 200, and a suction assembly 300. The conveying assembly 200 is installed inside the intelligent testing and drying chamber and is used to convey the support assembly 100 to the testing station and send it out after testing. The suction assembly 300 is installed on top of the testing and drying chamber and directly opposite the conveying assembly 200, and is used to draw in the component mixture gas dispersed in the gas after drying.

[0041] The support assembly 100 includes a support tray 110 and a central tube 120. The support tray 110 has a disc-shaped structure with an internal space for accommodating the closed fruits to be tested. The central tube 120 is vertically installed at the center of the support tray 110. The lower opening of the central tube 120 communicates with the internal space of the support tray 110, and the upper opening is used to connect with the suction assembly 300. The bottom of the support tray 110 is provided with a positioning structure that cooperates with the conveying assembly 200 to ensure the positional accuracy of the support tray 110 during the conveying process.

[0042] The conveying assembly 200 can be a conventional conveying device in the art, such as a chain conveyor, roller conveyor, or AGV (Automated Guided Vehicle). In this embodiment, the conveying assembly 200 preferably uses a chain conveyor, whose conveying chain plate is provided with positioning slots adapted to the bottom positioning structure of the support tray 110. After the conveying assembly 200 conveys the support assembly 100 to below the suction assembly 300, it aligns the support assembly 100 with the suction assembly 300 through centering positioning.

[0043] The suction assembly 300 includes a mounting frame 310, a suction tube 320, a tube telescopic mechanism 330, and a transmission mechanism 340. The mounting frame 310 is fixedly installed on the top of the testing and drying chamber, serving as the mounting base for the entire suction assembly 300. The transmission mechanism 340 is mounted on the mounting frame 310 and is driven by a drive mechanism (such as a servo motor). The tube telescopic mechanism 330 is installed at one end of the transmission mechanism 340, and the suction tube 320 is slidably installed within the tube telescopic mechanism 330.

[0044] The suction tube 320 is a long and slender tubular structure with a suction port 321 on its lower end sidewall for drawing in diffused gas. A sensor module 322 is installed near the suction port 321. The sensor module 322 includes a temperature sensor and can also integrate a humidity sensor, pressure sensor, etc., as needed. The temperature sensor is used to detect the drying temperature inside the tray 110. When the drying temperature reaches a preset value and a preset time (e.g., 5-10 minutes) has elapsed, the sensor module 322 sends a control signal to activate the drive mechanism, which drives the suction tube 320 to extend for suction detection.

[0045] The suction tube 320, driven by the conduit telescopic mechanism 330, extends downwards, bringing the suction port 321 close to the interior of the support tray 110 of the support assembly 100, thereby precisely drawing in the mixed gas dispersed on the surface of the closed fruit. The suction tube 320 is connected to the transmission mechanism 340 and the conduit telescopic mechanism 330, and the drawn gas is delivered to the infrared spectrometer through the gas passages inside the suction tube 320, the conduit telescopic mechanism 330, and the transmission mechanism 340.

[0046] Example 2

[0047] like Figures 3 to 8 As shown, the difference between this embodiment and Embodiment 1 is that the specific structure of the catheter telescopic mechanism 330 is described in detail.

[0048] The catheter telescopic mechanism 330 includes an inner connecting sleeve 331, an outer connecting sleeve 332, and a telescopic sleeve 333. The inner connecting sleeve 331 is a cylindrical structure, with its upper end mounted on the lower end of the drive shaft 341 of the transmission mechanism 340. The telescopic sleeve 333 is a cylindrical structure and is rotatably mounted on the outside of the inner connecting sleeve 331. The suction tube 320 passes through the inside of the inner connecting sleeve 331 and can rotate relative to the inner connecting sleeve 331. The outer connecting sleeve 332 is sleeved on the outside of the telescopic sleeve 333 and is fixedly connected to the guide rail 3421 of the transmission mechanism 340, and is driven by the guide rail 3421 to slide along the length direction (i.e., the vertical direction) of the telescopic sleeve 333.

[0049] The inner wall of the telescopic sleeve 333 has a forward spiral groove 3331 (i.e., a spiral groove with a clockwise thread direction), and the outer wall has a reverse spiral groove 3332 (i.e., a spiral groove with a counterclockwise thread direction). The pitch of the forward spiral groove 3331 and the reverse spiral groove 3332 can be designed according to the required telescopic speed and stroke.

[0050] A guide post 323 is fixedly installed at the end of the outer wall of the suction tube 320 away from the suction port 321. The guide post 323 extends into the forward spiral groove 3331 inside the telescopic sleeve 333 and slides in cooperation with the forward spiral groove 3331. A guide block 3321 is fixedly installed in the middle of the inner side of the outer connecting sleeve 332. The guide block 3321 extends into the reverse spiral groove 3332 on the outer side of the telescopic sleeve 333 and slides in cooperation with the reverse spiral groove 3332.

[0051] The inner connecting sleeve 331 has a constraint guide groove 3311 extending along its length. The guide post 323 of the suction tube 320 passes through the forward spiral groove 3331 and extends further into the constraint guide groove 3311, where it is slidably connected. The constraint guide groove 3311 guides and constrains the guide post 323, allowing the suction tube 320 to move linearly along the length of the inner connecting sleeve 331, and preventing it from rotating relative to the inner connecting sleeve 331.

[0052] The upper end of the telescopic sleeve 333 is rotatably connected to the inner connecting sleeve 331 via a retaining ring 334 and a retaining groove on the outside of the inner connecting sleeve 331. The retaining ring 334 is embedded in the retaining groove, allowing the telescopic sleeve 333 to rotate freely around the inner connecting sleeve 331, but it cannot move along the length of the inner connecting sleeve 331.

[0053] When the guide rail 3421 drives the outer connecting sleeve 332 to move up and down vertically, the guide block 3321 of the outer connecting sleeve 332 slides into the reverse spiral groove 3332 on the outer side of the telescopic sleeve 333. Since the telescopic sleeve 333 is limited vertically by the retaining ring 334 and cannot move up and down, the vertical movement of the outer connecting sleeve 332 drives the telescopic sleeve 333 to rotate around its axis via the reverse spiral groove 3332. When the telescopic sleeve 333 rotates, its inner forward spiral groove 3331 rotates accordingly, driving the suction tube 320 to move vertically via the guide post 323. Because the guide post 323 is simultaneously constrained by the constraint guide groove 3311, the suction tube 320 can only move linearly in the vertical direction and cannot rotate.

[0054] Through the aforementioned transmission principle, the vertical movement of the outer connecting sleeve 332 is converted into the vertical extension and retraction movement of the suction tube 320. Due to the combined effect of the forward spiral groove 3331 and the reverse spiral groove 3332, a specific transmission ratio exists between the extension and retraction speed of the suction tube 320 and the movement speed of the outer connecting sleeve 332, achieving a stroke amplification effect within a limited space. Furthermore, after the suction tube 320 retracts, the outer connecting sleeve 332 moves downwards to precisely cover the suction tube and block the suction port 321, thus opening and closing the air intake of the suction tube 320.

[0055] Example 3

[0056] like Figure 3 and 4As shown, the difference between this embodiment and embodiments one and two is that the specific structure of the transmission mechanism 340 is described in detail.

[0057] The transmission mechanism 340 includes a transmission shaft 341, a guide rail assembly 342, a guide cam 343, a fixed seat 344, a bushing 345, a rotary joint 346, a guide seat 347, a stop wheel 348, and a mating sleeve 349.

[0058] The fixed base 344 is fixedly mounted on the fixed frame 310. The drive shaft 341 is vertically arranged and rotatably mounted on the fixed base 344 via bearings. The upper end of the drive shaft 341 is connected to the output end of the drive mechanism (such as a servo motor). The guide cam 343 has a disc-shaped structure, is fixedly mounted on the fixed base 344, and is sleeved on the outside of the drive shaft 341. The end face of the guide cam 343 has a cam groove 3431, which is an annular groove, and its trajectory is designed according to the required guide rail motion law.

[0059] The bushing 345 is fixedly mounted on the drive shaft 341 and rotates together with the drive shaft 341. The guide rail assembly 342 includes guide rail one 3421 and guide rail two 3422, each of which is symmetrically mounted on the bushing 345 via a guide seat 347. The guide seat 347 guides and supports guide rail one 3421 and guide rail two 3422, allowing them to slide only in the vertical direction.

[0060] One end (upper end) of guide rail 3421 is slidably connected to the cam groove 3431 of guide cam 343 via abutment wheel 348, and the other end (lower end) of guide rail 3421 is fixedly connected to outer connecting sleeve 332. One end (upper end) of guide rail 3422 is slidably connected to the cam groove 3431 of guide cam 343 via abutment wheel 348, and the other end (lower end) of guide rail 3422 is fitted with mating sleeve 349.

[0061] When the drive mechanism rotates the transmission shaft 341, the bushing 345 drives the guide rails 3421 and 3422 to rotate synchronously. The abutment wheels 348 at the upper ends of the guide rails 3421 and 3422 roll along the cam groove 3431 of the guide cam 343. Because the trajectory of the cam groove 3431 undulates in the vertical direction, the guide rails 3421 and 3422 will also reciprocate in the vertical direction while rotating with the bushing 345. By reasonably designing the trajectory of the cam groove 3431, the guide rails 3421 and 3422 can achieve staggered vertical movement—that is, one rises while the other falls, or the two move at different speeds and strokes.

[0062] The drive shaft 341 has a hollow structure with a through-hole gas channel. The lower end of the drive shaft 341 is connected to and communicates with the inner connecting sleeve 331, and the upper end of the drive shaft 341 is connected to the air inlet pipe of the infrared spectrometer via a rotary joint 346. The rotary joint 346 is used to achieve a sealed gas connection between the rotating component (drive shaft 341) and the stationary component (air inlet pipe).

[0063] The mating sleeve 349 has a cylindrical structure, and its lower end is provided with a mating interface (such as a tapered interface or a sealing ring interface) that is compatible with the upper end of the central tube 120. The interior of the mating sleeve 349 is connected to the internal air passage of the guide rail 3422, and the interior of the guide rail 3422 is connected to the internal air passage of the drive shaft 341.

[0064] When guide rail 1 3421 drives the outer connecting sleeve 332 to move up and down, as mentioned above, the guide tube 320 is driven to extend and retract up and down through the guide tube telescopic mechanism 330. At the same time, guide rail 2 3422 drives the docking sleeve 349 to move up and down synchronously. Due to the trajectory design of the cam groove 3431, the docking sleeve 349 contacts and aligns with the central tube 120 before the guide tube 320 during its downward movement. Specifically, before the guide port 321 of the guide tube 320 extends into the central tube 120, the docking sleeve 349 has already completed a sealed docking with the upper end of the central tube 120, establishing a complete air passage from the inside of the support tray 110 → central tube 120 → docking sleeve 349 → guide tube 320 → drive shaft 341 → rotary joint 346 → infrared spectrometer inlet pipe. Subsequently, the suction tube 320 continues to extend downwards, passing through the docking sleeve 349 and the central tube 120, so that the suction port 321 extends into the inside of the tray 110 close to the position of the closed fruit to be tested, and begins to draw in the diffused gas.

[0065] Example 4

[0066] This embodiment will provide a detailed description of the working process of the intelligent fruit drying component detection device of the present invention.

[0067] Step 1: Loading. The operator evenly spreads the closed fruits (such as walnuts) to be tested in the tray 110, ensuring that the closed fruits are spread flat in the tray 110 so that the infrared drying system can heat the closed fruits evenly.

[0068] Step Two: Conveying into the Chamber. The conveying assembly 200 conveys the support assembly 100 containing the closed fruit to be tested into the intelligent detection and drying chamber, and transports it directly below the suction assembly 300. The conveying assembly 200 uses a centering and positioning device (such as a photoelectric sensor in conjunction with a positioning block) to precisely align the center tube 120 of the support tray 110 with the docking sleeve 349 of the suction assembly 300 in the vertical direction, with the positioning accuracy controlled within ±1mm.

[0069] Step 3: Infrared Drying. The infrared drying system in the intelligent detection drying chamber is activated to heat and dry the closed fruits to be tested in tray 110. The infrared drying system can use infrared heating tubes or infrared heating plates. The heating temperature is set according to the type of closed fruit and the drying process requirements, generally controlled within the range of 60-120℃.

[0070] Step 4: Temperature Monitoring and Start-up Judgment. A temperature sensor in the sensor module 322, installed at the end of the suction tube 320, monitors the temperature inside the tray 110 in real time. Once the preset drying temperature is reached, the system starts timing. After a preset drying time (e.g., 10-30 minutes, the specific time depending on the type of fruit and the target components being detected), the sensor module 322 sends a start signal to control the drive mechanism to start.

[0071] Step 5: The suction tube extends and connects. The drive mechanism (servo motor) starts, driving the transmission shaft 341 to rotate. The transmission shaft 341 drives the guide rail 1 3421 and guide rail 2 3422 to rotate via the bushing 345. The abutment wheel 348 at the upper end of the guide rail 1 3421 and guide rail 2 3422 rolls along the cam groove 3431 of the guide cam 343, driving the guide rail 1 3421 and guide rail 2 3422 to move downward in the vertical direction.

[0072] Guide rail 2 3422 drives docking sleeve 349 to move downwards. Docking sleeve 349 first docks with and seals the upper end of central tube 120. Then, guide rail 1 3421 drives outer connecting sleeve 332 downwards. The guide block 3321 of outer connecting sleeve 332 engages with the reverse spiral groove 3332 on the outer side of telescopic sleeve 333, driving telescopic sleeve 333 to rotate. The forward spiral groove 3331 on the inner side of telescopic sleeve 333 drives suction tube 320 to extend downwards along the constraint guide groove 3311 of inner connecting sleeve 331 via guide post 323. Suction tube 320 passes through docking sleeve 349 and central tube 120, causing suction port 321 to extend into the tray 110, closely contacting the surface of the test result.

[0073] Step Six: Gas Suction and Detection. After the guide tube 320 extends into position, the infrared spectrometer starts the suction pump, drawing the mixed gas dispersed in the tray 110 into the infrared spectrometer for component analysis through the gas path formed by the guide port 321 → guide tube 320 → inner connecting sleeve 331 → drive shaft 341 → rotary joint 346 → air inlet pipe. Because the guide port 321 is close to the surface of the fruit to be tested, the concentration of the target component in the suction gas is much higher than that of traditional large-scale suction methods, greatly improving detection sensitivity and accuracy.

[0074] Step Seven: Suction Tube Retraction and Exit from Chamber. After the inspection is completed, the drive mechanism reverses, the transmission shaft 341 rotates in the opposite direction, and guide rails 3421 and 3422 move upward. The suction tube 320 retracts upward under the drive of the guide tube telescopic mechanism 330, and the docking sleeve 349 disengages from the central tube 120. Subsequently, the conveying assembly 200 sends the supporting assembly 100 out of the intelligent inspection and drying chamber, completing the entire drying and inspection process.

[0075] Example 5

[0076] The difference between this embodiment and the previous embodiment is that the tray 110 may be provided with a partition structure to divide the internal space of the tray 110 into multiple independent sub-regions, each of which can be filled with different batches or different types of closed fruits. Correspondingly, the lower end of the central tube 120 may be provided with multiple branch ports, each corresponding to a different sub-region, or a rotatable gate mechanism may be provided to achieve selective suction of gas from different sub-regions. This design enables the device to simultaneously dry and test multiple closed fruit samples, improving testing efficiency.

[0077] In addition, sensor module 322 may also include a humidity sensor and a pressure sensor. The humidity sensor is used to detect the humidity of the gas inside the tray 110 to help determine the degree of drying of the closed fruit; the pressure sensor is used to detect the air pressure in the suction pipeline to ensure that the suction pump is working properly and to prevent pipeline blockage or leakage.
