Description

Technical Field

[0001] The present invention relates to the technical field of rapid carotenoid detection, in particular to a rapid carotenoid detector and a use method thereof. Background Art

[0002] Carotenoids are a common natural pigment in aquatic organisms and are widely found in red, orange-red, yellow and other pigments in fungi, algae, animals and plants. They can act as a precursor of VA to participate in the functional regulation of organisms and have multiple biological activities. They are also a natural feed additive and colorant with antioxidant, immunomodulatory, anti-cancer, and anti-aging effects.

[0003] At present, the detection method for measuring carotenoids in shellfish is to first dissect the living body, extract the carotenoids in the tissue, and then use optical instruments to measure. It is impossible to carry out rapid and accurate measurement on living bodies. In some use scenarios where living bodies need to be preserved, such as scientific research, breeding and production of new carotenoid-enriched varieties, and commercial seedlings, the carotenoid content of shellfish needs to be measured and kept alive for screening. Existing technical means cannot achieve this and can only be observed with the naked eye, which wastes a lot of manpower and cannot guarantee accuracy. For this reason, we propose a rapid carotenoid detector and its use method. Summary of the Invention

[0015] A rapid carotenoid detection method comprises the following steps:

[0016] S1: During the carotenoid test of live shellfish to be tested, the live shellfish are placed on a carrying plate of a carrying box. After placement, the carrying plate and the live shellfish on the carrying plate are pulled down into the carrying box by a pulling assembly;

[0017] S2: During the descending process of the carrying plate, the first flow holes of the first circular plate and the second flow holes of the second circular plate communicate with each other, so that part of the liquid in the carrying box is transported to the top of the carrying plate through the first flow holes and the second flow holes, and the placed live shellfish is immersed in the liquid. The action of the liquid on the live shellfish assists in the rapid opening operation of the live shellfish;

[0018] S3: After the live shellfish opens its mouth, the supporting plate and the live shellfish placed on the supporting plate are lifted and reset by the line-releasing operation of the pulling assembly and the reset support of the supporting assembly.

After closing, the live shellfish is irradiated by the irradiation lamp and photographed by the image acquisition camera, and the flesh quality and color of the inner side of the live shellfish after opening are photographed. The photographed image is processed by the processor on the computer and compared with the data in the database. Due to the different carotenoid content in the shellfish, its soft tissue will show different colors and depths. In the database, each different color image corresponds to a precisely measured carotenoid content value. By comparing the actual photographed color with the data in the database, the carotenoid content value is obtained and displayed on the display, thereby realizing a rapid carotenoid detection operation for the live shellfish;

[0020] S5: In the process of pushing the detection cover toward the carrying box, the detection cover is abutted against the extrusion plate, pushing the extrusion plate to move downward on the detection table. Through transmission, each group of second flow holes is staggered with each group of first flow holes. Through the staggered effect, the light transmittance when the second flow holes are connected to the first flow holes is avoided, which causes the influence of other uncertain light sources on the image during the photo identification process, thereby further ensuring the accuracy of detection judgment.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] During the process of carotenoid detection on the living shellfish to be detected, the present invention obtains the carotenoid content value through the mutual cooperation of the detection component, the support component and the pulling component, and displays the detected value on the display, thereby realizing a rapid carotenoid detection operation on the living shellfish. In addition, during the detection process, through the setting and circulation of the liquid and the subsequent shading operation, the detection efficiency is improved while the detection accuracy is guaranteed.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figures 1-8 The rapid carotenoid detector shown in the figure includes a detection table 101 for rapid detection of shellfish carotenoids. A plurality of rotating wheels 102 are fixed at the four corners of the lower end of the detection table 101, and further includes:

[0036] The detection component for carrying shellfish and detecting carotenoids fixed on the detection table 101 includes a carrying box 201 fixed on the detection table 101, and a carrying plate 202 for carrying and placing shellfish is provided on the carrying box 201. The shape of the carrying box 201 and the carrying plate 202 matches the shape of the shellfish and is arranged in a fan shape. The interior of the carrying box 201 is provided with a supporting component for assisting the supporting plate 202 and a pulling component for pulling the supporting plate 202. The interior of the carrying box 201 is provided with a supporting component for assisting the detection process. The liquid in the shellfish opening is provided on the carrying plate 202 with a circulation component for assisting liquid circulation. The upper end hinge of the carrying box 201 is provided with a detection cover 203 for covering the carrying box 201. The detection cover 203 is installed with an image acquisition camera 204 for assisting detection and an irradiation lamp 205 for auxiliary lighting. The detection cover 203 is provided with a computer, which is provided with a processor for processing images taken by the image acquisition camera 204, a data comparison library for comparing images, and a display for displaying the compared data.

[0037] It should be noted here that the principle of the entire detection is that carotenoids are natural pigments. Within a certain concentration range, the higher the content, the brighter and darker the tissue color. This color characteristic provides the basis for detecting carotenoid content through image recognition, including:

[0038] The image acquisition camera 204 converts the collected light signal into an electrical signal, thereby generating a digital image;

[0039] The processor processes and analyzes the digital image acquired by the image acquisition camera 204, including image preprocessing, color feature extraction, comparison with the database, and content estimation;

[0040] The data comparison library serves as a reference standard for detection and provides a basis for sample image comparison and content estimation. It stores a large number of scallop images with known carotenoid content and their corresponding content information, and is the key support for the entire detection technology. In the database construction process, shellfish samples with different carotenoid content are subjected to precise chemical analysis, such as high-performance liquid chromatography to determine their content. At the same time, high-precision image acquisition equipment is used to obtain sample images under standardized lighting and shooting conditions. The images and corresponding content information are stored one by one, forming a database that can be queried and matched by image features. See Figure 9 The actual test diagram made in

[0041] It is worth noting that the image acquisition camera 204, the processor, the data comparison library and the display are conventional technical means for image recognition, data processing and comparison in this application, and their working principles and connection methods are not described in detail here.

[0042] During the carotenoid detection process of the live shellfish to be detected, the carotenoid content value is obtained through the mutual cooperation of the detection component, the support component and the pulling component, and the detected value is displayed on the display, thereby realizing the rapid carotenoid detection operation of the live shellfish. In addition, during the detection process, the setting and circulation of the liquid and the subsequent shading operation are used to improve the detection efficiency while ensuring the accuracy of the detection.

[0043] Preferably, the circulation assembly includes a first circular plate 501 centrally fixed on the carrier plate 202, the lower end of the first circular plate 501 being rotatably connected to a second circular plate 502, the first circular plate 501 being provided with a plurality of first circulation holes 503, the second circular plate 502 being provided with a plurality of second circulation holes 504 for communicating with the first circulation holes 503, and a rotating assembly for rotating the second circular plate 502 being provided inside the carrier box 201;

[0044] It should be noted that when liquid needs to pass through and fall back, the groups of first flow holes 503 on the first circular plate 501 are respectively connected to the groups of second flow holes 504 on the second circular plate 502. During the process of passing through and falling back on the liquid carrying plate 202, the liquid flows over the placed live shellfish. Through the fluid action of the liquid, impurities such as floating mud on the surface of the live shellfish and the inside of the open mouth are removed, facilitating subsequent more accurate detection and identification.

[0045] It is worth noting here that the liquid is clean sand-filtered seawater. When shellfish are in a clean sand-filtered seawater environment, the osmotic pressure inside and outside their bodies is balanced, and the shellfish's own physiological regulation mechanism will not be disturbed by the change in osmotic pressure. The water conditions in the shellfish's natural living environment are simulated, making it more likely for the shellfish to open their mouths naturally in a relatively comfortable state. In addition, appropriately increasing the water temperature can also help maintain the vitality of the shellfish and avoid closing the shells due to cold stimulation.

[0046] Preferably, the rotating assembly includes a spline cylinder 601 rotatably connected to the interior of the carrying box 201, a spline shaft 602 is slidably connected to the spline cylinder 601, one end of the spline shaft 602 is fixed to the lower end of the second circular plate 502, the first circular plate 501, the second circular plate 502 and the spline shaft 602 are concentrically arranged, and a driving assembly for driving the spline cylinder 601 is provided inside the carrying box 201;

[0047] It should be noted here that: the spline cylinder 601 is forced to rotate through the driving component. During the rotation of the spline cylinder 601, the second circular plate 502 is rotated at the lower end of the first circular plate 501 through the connection and transmission effect between the spline cylinder 601 and the spline shaft 602. Through the rotation of the second circular plate 502, each group of second flow holes 504 is staggered with each group of first flow holes 503. Through the staggered effect, the light transmittance of the second flow holes 504 when communicating with the first flow holes 503 is avoided, which causes the influence of other uncertain light sources on the image during the photo recognition process.

[0048] Preferably, the drive assembly includes a push plate 701 slidably connected to the carrying box 201, a rack 702 is fixed to one end of the push plate 701 located inside the carrying box 201, a ring gear 703 is fixed to the outside of the spline cylinder 601, the rack 702 and the ring gear 703 are meshed with each other, and a transmission assembly for driving the push plate 701 is provided on the outside of the carrying box 201;

[0049] It should be noted here that: through the transmission assembly, the push plate 701 is forced to move toward the inside of the carrying box 201. During the movement of the push plate 701, the rack 702 is driven to move. During the movement of the rack 702, the spline cylinder 601 is forced to rotate through the mutual engagement transmission between the rack 702 and the ring gear 703.

[0050] Preferably, the transmission assembly includes a transmission plate 801 disposed on the outside of the carrying box 201, with an inclined slot 802 formed on the transmission plate 801, a transmission pin 803 being slidably connected to the inclined slot 802, one end of the transmission pin 803 being fixed to the push plate 701, an extrusion plate 804 being slidably connected to the detection platform 101, one end of the extrusion plate 804 being located above the detection platform 101 for abutting against the covered detection cover 203 for transmission, the other end of the extrusion plate 804 being fixed to the upper end of the transmission plate 801, and a connecting assembly for connecting and guiding the extrusion plate 804 being provided on the outside of the carrying box 201;

[0051] It should be noted here that: in the process of pushing the detection cover 203 toward the carrying box 201, the detection cover 203 is offset from the extrusion plate 804, pushing the extrusion plate 804 to move downward on the detection platform 101. In the process of movement of the extrusion plate 804, the transmission plate 801 is driven to move downward synchronously. In the process of movement of the transmission plate 801, the offset transmission effect of the inclined groove 802 and the transmission pin 803 and the connection effect of the transmission pin 803 are used to force the push plate 701 to move toward the inside of the carrying box 201.

[0052] Preferably, the connecting assembly includes a fixing plate 901 fixed to the outside of the carrying box 201, a connecting plate 902 fixed to the extrusion plate 804, and a plurality of groups of T-shaped rods 903 slidably connected to the fixing plate 901, one end of each group of T-shaped rods 903 being fixed to the connecting plate 902, and a first spring 904 being sleeved on the outside of each group of T-shaped rods 903, and the two ends of the first spring 904 being respectively connected to one end of the T-shaped rod 903 and the fixing plate 901;

[0053] It should be noted here that the fixing plate 901 , the connecting plate 902 and the T-bar 903 are used to assist in guiding the sliding of the squeeze plate 804 after being stressed, and the first spring 904 is used to reset the squeeze plate 804 after movement.

[0054] Preferably, the support assembly includes two sets of sleeves 301 fixed inside the carrying box 201, with a slide rod 302 slidably connected to the sleeve 301, one end of the slide rod 302 is fixed to the lower end of the carrying plate 202, and a second spring 303 is sleeved on the outer side of the sleeve 301, with the two ends of the second spring 303 respectively abutting against the interior of the carrying box 201 and the lower end of the carrying plate 202;

[0055] It should be noted that the two sets of sleeves 301 and the two sets of slide bars 302 assist the supporting plate 202 to move downward and telescopically after being stressed, and the second spring 303 facilitates the restoration of the supporting plate 202 after the downward movement.

[0056] Preferably, the pulling assembly includes a support frame 401 fixed to the lower end of the carrying box 201, a winding wheel 402 is rotatably connected to the support frame 401, a pull rope 403 is wound around the winding wheel 402, one end of the pull rope 403 passes through the interior of the carrying box 201 and is fixed to the bottom of the carrying plate 202, and a driving motor 404 for rotating the winding wheel 402 is installed on the support frame 401;

[0057] It should be noted here that: the winding wheel 402 is driven to rotate by the driving motor 404. During the rotation of the winding wheel 402, the pull rope 403 is released or reeled in. During the reeling of the pull rope 403, the pull rope 403 is used to pull the supporting plate 202 to descend inside the supporting box 201.

[0058] Preferably, a circulation assembly for assisting the circulation of liquid inside the carrying box 201 is provided inside the testing platform 101. The circulation assembly includes a U-shaped circulation pipe 1001 installed on both sides of the carrying box 201. A circulation pump 1002 is installed inside the testing platform 101. The two ends of the U-shaped circulation pipe 1001 are respectively connected to the inlet and outlet of the circulation pump 1002. A filter screen for filtering the liquid is installed inside the U-shaped circulation pipe 1001.

[0059] It should be noted here that: the liquid circulates between the carrying box 201 and the U-shaped circulation pipe 1001 through the driving action of the circulation pump 1002. During the circulation process, impurities in the liquid are filtered through the filter net to facilitate the continuous use of the liquid.

[0060] In this scheme: A method for rapid detection of carotenoids comprises the following steps:

[0061] S1: During the carotenoid test of live shellfish, the live shellfish are placed on the carrying plate 202 of the carrying box 201. After the placement is completed, the carrying plate 202 and the live shellfish on the carrying plate 202 are pulled down into the interior of the carrying box 201 by a pulling assembly;

[0062] S2: During the process of the carrying plate 202 descending, the communication between the groups of first flow holes 503 on the first circular plate 501 and the groups of second flow holes 504 on the second circular plate 502 allows part of the liquid inside the carrying box 201 to be transported to the top of the carrying plate 202 through the first flow holes 503 and the second flow holes 504, so that the placed live shellfish are immersed in the liquid. The action of the liquid on the live shellfish assists in the rapid opening operation of the live shellfish.

[0063] S3: After the live shellfish opens its mouth, the supporting plate 202 and the live shellfish placed on it are lifted and reset by the pay-off operation of the pulling assembly and the reset support of the supporting assembly on the supporting plate 202. During the lifting and reset process, the liquid above the supporting plate 202 flows back to the interior of the carrying box 201 through the groups of first flow holes 503 and second flow holes 504. In the process of the liquid passing through and falling back on the supporting plate 202, the liquid flows over the placed live shellfish. The fluid action of the liquid removes impurities on the surface of the live shellfish and the inside of the open mouth, facilitating subsequent more accurate detection and identification.

[0064] S4: After the carrying plate 202 and the living shellfish placed on the carrying plate 202 are raised and reset, the detection cover 203 is pushed toward the carrying box 201 and covered with the carrying box 201, so that the living shellfish above the carrying plate 202 is inside the detection cover 203. After covering, the living shellfish is irradiated by the irradiation lamp 205 and photographed by the image acquisition camera 204, and the meat quality and color of the inner side of the living shellfish after opening are photographed. The photographed image is processed by the processor on the computer and compared with the data in the database. Due to the different carotenoid content in the shellfish, its soft tissue will show different colors and depths. In the database, each image of different colors corresponds to a precisely measured carotenoid content value. By comparing the actual photographed color with the data in the database, the carotenoid content value is obtained and displayed on the display, thereby realizing a rapid carotenoid detection operation for the living shellfish;

[0065] S5: In the process of pushing the detection cover 203 toward the carrying box 201, the detection cover 203 is offset against the extrusion plate 804, pushing the extrusion plate 804 to move downward on the detection platform 101. During the movement of the extrusion plate 804, the transmission plate 801 is driven to move downward synchronously. During the movement of the transmission plate 801, the offset transmission effect between the inclined slot 802 and the transmission pin 803 and the connection effect of the transmission pin 803 cause the push plate 701 to be forced to move toward the inside of the carrying box 201. During the movement of the push plate 701, the rack 702 is driven to move. During the movement of the rack 702, the rack 701 is connected to the rack 701. 2 and the gear ring 703, the spline cylinder 601 is forced to rotate. During the rotation of the spline cylinder 601, the second circular plate 502 is rotated at the lower end of the first circular plate 501 through the connection and transmission between the spline cylinder 601 and the spline shaft 602. Through the rotation of the second circular plate 502, each group of second flow holes 504 is staggered with each group of first flow holes 503. The staggered effect avoids the influence of other uncertain light sources on the image during the photo recognition process caused by the light transmittance when the second flow holes 504 are connected to the first flow holes 503, thereby further ensuring the accuracy of detection and judgment.

10. A method for rapid detection of carotenoids, comprising the method comprising: The following steps are involved: S1: During the process of performing carotenoid testing on the live shellfish to be tested, the live shellfish is placed on the carrying plate (202) of the carrying box (201). After the placement is completed, the carrying plate (202) and the live shellfish on the carrying plate (202) are pulled down into the interior of the carrying box (201) by a pulling assembly; S2: During the process of the carrier plate (202) descending, the first flow holes (503) of each group on the first circular plate (501) and the second flow holes (504) of each group on the second circular plate (502) communicate with each other, so that part of the liquid inside the carrier box (201) is transported to the top of the carrier plate (202) through the first flow holes (503) and the second flow holes (504), and the placed live shellfish is immersed in the liquid. The action of the liquid on the live shellfish assists in the rapid opening operation of the live shellfish; S3: After the live shellfish opens its mouth, the supporting plate (202) and the live shellfish placed on the supporting plate (202) are lifted and reset by the line-releasing operation of the pulling component and the reset support of the supporting component on the supporting plate (202). During the lifting and reset process, the liquid above the supporting plate (202) flows back to the interior of the carrying box (201) through each group of first flow holes (503) and second flow holes (504); S4: After the carrying plate (202) and the living shellfish placed on the carrying plate (202) are lifted and reset, the detection cover (203) is pushed to move toward the carrying box (201) and cover the carrying box (201), so that the living shellfish above the carrying plate (202) is inside the detection cover (203). After covering, the living shellfish is irradiated by the irradiation lamp (205) and photographed by the image acquisition camera (104), and the meat quality and color of the inside of the living shellfish after opening are photographed. The photographed image is processed by a processor on the computer and compared with the data in the database. Due to the different carotenoid content in the shellfish, its soft tissue will present different colors and depths. In the database, each image of different colors corresponds to a precisely measured carotenoid content value. By comparing the actual photographed color with the data in the database, the carotenoid content value is obtained and the compared value is displayed on the display, thereby realizing a rapid carotenoid detection operation for the living shellfish; S5: In the process of pushing the detection cover (203) toward the carrying box (201), the detection cover (203) and the extrusion plate (804) are abutted against each other, pushing the extrusion plate (804) to move downward on the detection platform (101). Through transmission, each group of second flow holes (504) is staggered with each group of first flow holes (503). Through the staggered effect, the light transmittance when the second flow holes (504) and the first flow holes (503) are connected is avoided, which prevents the presence of other uncertain light sources on the image during the photo recognition process, thereby further ensuring the accuracy of the detection judgment.
