[0002] In the modern food supply chain, numerous stages are involved in food production, processing, transportation, and sales, significantly increasing the likelihood of food being exposed to various contamination and quality risks. From an agricultural production perspective, the widespread use of pesticides and veterinary drugs plays a crucial role in increasing yields and controlling pests and diseases; however, excessive or improper use can lead to excessive pesticide and veterinary drug residues. During food processing, some unscrupulous businesses may illegally add various additives to improve taste, appearance, or extend shelf life. Furthermore, food can be contaminated with heavy metals, microorganisms, and toxins during storage and transportation.

[0003] In today's society, food comes in a wide variety of forms, including agricultural products, meat and poultry, aquatic products, beverages, alcoholic beverages, dairy products, canned foods, and food packaging materials. Different types of food have different production processes, raw material sources, and quality control requirements. The sources of food are also extremely diverse, including locally produced, transported from other regions, and imported foods. In this complex and ever-changing food safety risk environment, traditional single-indicator testing devices are no longer sufficient to meet the needs of comprehensively and accurately assessing food quality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic food safety testing device and its usage method, solving the problem that traditional single-indicator testing devices are no longer sufficient to meet the needs of comprehensive and accurate food quality assessment.

[0032] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides an automatic food safety testing device, including a housing 1. An electric slide rail 2 is installed inside the housing 1. A sliding frame 3 is slidably connected inside the electric slide rail 2. A pipetting mechanism 4 is installed on the lower surface of the sliding frame 3. An electric slide rail 5 is installed inside the housing 1. A sliding frame 6 and a sliding frame 7 are slidably connected inside the electric slide rail 5. A sample bottle is placed on the upper surface of the sliding frame 6. A transfer mechanism 8 is installed on the upper surface of the sliding frame 7. The housing 1 contains a detector 9, an incubator 10, a centrifuge 11, a shaker 12, a sieve 13, a stirrer 14, and a waste liquid tank 15. A placement rack 16 is installed on the upper inner wall of the housing 1.

[0034] Specifically, the electric slide rail 2 and the sliding frame 3 work together to drive the pipetting mechanism 4 to slide, thereby expanding the application range of the pipetting mechanism 4. The electric slide rail 5 and the sliding frame 6 work together to drive the sample bottle to slide, and multiple sample bottles can be used. The electric slide rail 5 and the sliding frame 7 work together to drive the transfer mechanism 8 to slide, expanding the application range of the transfer mechanism 8. In some embodiments of the present invention, the detector 9 is a fluorescence analyzer; the oscillator 12 is a vortex mixer. For ease of operation, the detector 9, incubator 10, centrifuge 11, oscillator 12, sieve 13, stirrer 14 and waste liquid tank 15 can be arranged in a straight line. The placement rack 16 is used to place unused sample bottles.

[0035] Please see the appendix Figure 1 - Appendix Figure 3 The pipetting mechanism 4 includes a robotic arm 401, the upper surface of which is disposed on the lower surface of the sliding frame 3, and a pipette 402 is disposed on the outer wall of the robotic arm 401.

[0036] Specifically, the robotic arm 401 can move at multiple angles, thereby moving the pipette 402, which can be used to transfer liquids.

[0037] Please see the appendix Figure 2 - Appendix Figure 3 The transfer mechanism 8 includes a second robotic arm 801, the lower surface of which is disposed on the upper surface of the sliding frame 7, and an electric gripper 802 is disposed on the outer wall of the second robotic arm 801.

[0038] Specifically, robotic arm 2 801 can move at multiple angles, and robotic arm 2 801 can drive electric gripper 802 to move. Electric gripper 802 can be used to grip sample bottles and bottle stoppers, thereby transferring sample bottles arbitrarily.

[0039] Please see the appendix Figure 1 - Appendix Figure 4 The outer wall of the detector 9 is fitted with a card slot 17, the lower surface of the card slot 17 is set on the inner wall of the housing 1, the inside of the detector 9 is equipped with a control panel 18, the inside of the detector 9 is slidably connected with a detection card 19, the outer wall of the detection card 19 is equipped with a QR code 20, the upper surface of the housing 1 is equipped with a placement box 21, and the inside of the placement box 21 is equipped with a cleaning fluid bottle 22.

[0040] Specifically, 17 is used to store 19. After 19 is used, 19 can be pushed directly into the interior of 17 from the side. The QR code 20 on 19 contains the name of the hazardous factor, the food matrix to be tested, and the corresponding pretreatment process. The placement box 21 is used to place the cleaning liquid bottle 22. The interior of the cleaning liquid bottle 22 is used to store the cleaning liquid, such as ethanol.

[0041] Please see the appendix Figure 5 A method for using an automatic food safety detection device includes the following steps:

[0042] Weigh the sample and select the corresponding test card 19;

[0043] Insert the test card 19 into the tester 9. Multiple test cards 19 can be used. According to the test items, the test cards 19 are spliced ​​and combined to start the processing flow.

[0044] Use a pipette 402 to take the supernatant and add it to the sample vial;

[0045] Place the sample vial in an incubator at 10°C for incubation.

[0046] Add the test droplet to the corresponding test card 19, and call up the relevant curve by combining the QR code 20 on the test card 19 to automatically calculate the result;

[0047] Use a pipette 402 to extract the cleaning solution for cleaning, and place the waste liquid in the waste liquid tank 15.

[0048] Specifically, using a balance with the required accuracy, accurately weigh an appropriate amount of sample according to the testing standards. The weighed sample should be properly stored to avoid contamination or changes in its properties. Insert the selected test card into the designated slot of the testing instrument according to the instrument's operating instructions. During insertion, keep the test card clean and avoid touching the testing area. After insertion, start the testing instrument and enter the testing process. Transfer the weighed sample to the sample container in the stirrer. Place the sample bottle in the incubator and set the temperature and time according to the requirements of the testing item. During incubation, ensure the temperature of the incubator is stable to avoid temperature fluctuations affecting the test results. Use a pipette to draw an appropriate amount of the test solution and add it to the corresponding testing area of ​​the test card. Control the dripping speed and volume during the dripping process. Each test card has a unique QR code. The testing instrument scans this QR code to automatically retrieve the relevant standard curve and automatically calculate the test results. The results can be transmitted to the "Food Safety Data Management and Analysis System" for quality and safety monitoring. Use a pipette to extract cleaning solution to clean the used instruments. Place the cleaning waste solution in the waste solution tank. During cleaning, add cleaning solution by taking out the cleaning solution bottle 22 for convenient and timely replenishment. The bottle is placed on the upper surface of the tank 1 for easy access.

[0049] Please see the appendix Figure 5 Before incubation, place the sample bottle in a centrifuge (11) for centrifugation.

[0050] Specifically, based on the properties of the sample and the testing requirements, set the centrifuge speed and centrifugation time. Start the centrifuge to allow the sample to separate into layers under centrifugal force.

[0051] Please see the appendix Figure 5 Before centrifugation, place the sample vial into shaker 12 and shake.

[0052] Place the sample vial containing the supernatant into the shaker, and set the shaking frequency and time according to the testing requirements. Start the shaker to allow the liquid in the sample vial to vibrate thoroughly, promoting the uniform distribution and reaction of the components in the sample.

[0053] Please see the appendix Figure 5 Before using pipette 402 to take the supernatant, first put the sample to be tested into stirrer 14 and start stirrer 14.

[0054] Specifically, adjust the stirring speed and time of the stirrer according to the properties of the sample and the testing requirements. Start the stirrer to ensure the sample is thoroughly mixed, and then use a pipette to collect the supernatant.

[0055] Please see the appendix Figure 5 Before stirring, the supernatant should be sieved through a sieve (13 sieves).

[0056] After the sampling step, the supernatant can be sieved to remove impurities, thereby improving the speed and accuracy of the test.

[0057] The second sliding frame 6 drives the sample bottle to slide, and then the sample bottle is transferred by the transfer mechanism 8. The transfer mechanism 8 removes or installs the stopper of the sample bottle. The first sliding frame 3 drives the pipetting mechanism 4 to slide, and the pipetting mechanism 4 adds solution into the sample bottle.

[0058] Specifically, the sliding frame 2 moves the sample vials arbitrarily. When it is necessary to remove the sample vials from or place them into the instrument, the robotic arm 2 can move the electric gripper to hold and transfer the sample vials. During each step, the stopper of the sample vials can be removed first, and the sliding frame 3 can move the pipetting mechanism 4 to align the pipette 402 with the sample vials. Liquid can then be added to the sample vials, and the stopper can be replaced by the transfer mechanism 8.

[0059] Based on the aforementioned apparatus and methods, this solution provides the following five specific testing procedures for grains, meat, eggs / milk, fruits and vegetables, and aquatic products.

[0060] Detection direction:

[0061]

[0062] Example 1:

[0063] This embodiment takes the detection of grains as an example and specifically includes the following steps:

[0064] First, weigh an appropriate amount of sample and enter the product name and weight on the control panel 18 of the detector 9. Then, select the test card 19 for Escherichia coli O157, Salmonella, Staphylococcus aureus, Bacillus cereus, enterotoxins (ABCDE), lead, and cadmium, and assemble the test card 19.

[0065] Insert the combined test card 19 into the tester 9. After the tester 9 recognizes the QR code 20 on the test card 19, it calls the corresponding preprocessing process to start running.

[0066] Place the sample to be tested into the stirrer 14, add 10 ml of diluent, compact and break the sample, extract the supernatant through the pipette 402, and sieve the supernatant through the sieve 13.

[0067] Using pipette 402, 4 ml and 3 ml of supernatant were added to sample bottle 1 and sample bottle 2 respectively, and the sample bottle caps were closed by the transfer mechanism 8.

[0068] The transfer mechanism 8 places sample vials No. 1 and No. 2 into shaker 12 and shakes for 4 minutes before removing them;

[0069] The transfer mechanism 8 places sample bottles No. 1 and No. 2 into centrifuge 11 and centrifuges for 3 minutes, and then places them on the sliding rack 2 6;

[0070] Slide the slide holder 2 6 and, in conjunction with the pipetting mechanism 4, add quantitative reagent A and reagent B to sample bottle 1 respectively. Reagent A is a neutralizing solution and reagent B is a diluent containing a chelating agent. Mix well by shaking up and down with shaker 12, and place in incubator 10 to incubate at 37°C for 8 minutes.

[0071] Then, use a sampling needle to draw the test solution from sample bottle 1 and add 4 drops to 120 μL of the solution to the corresponding lead and cadmium detection card 19 using a pipetting mechanism; draw the test solution from sample bottle 2 and add 120 μL of the solution to the corresponding detection card 19.

[0072] After sequential testing, the test card 19 is ejected from the side of the detector 9 into the card slot 17, and the T-line and C-line are observed. The relevant curves are retrieved using the QR code 20 on the test card 19, and a quantitative curve is generated after testing. This curve is associated with the substance detected by the test card 19 for easy retrieval. The results are automatically calculated and displayed on the control panel 18.

[0073] After the test is completed, the cleaning waste liquid is placed in the waste liquid tank. During cleaning, the cleaning liquid is added by taking out the cleaning liquid bottle 22, which makes it convenient to add cleaning liquid in time. The cleaning liquid is extracted by the pipetting mechanism 4, and the instruments of each unit are automatically cleaned. The waste liquid is then extracted into the waste liquid tank 15.

[0077] Insert the combined test card 19 into the tester 9 in sequence. After the tester 9 recognizes the QR code 20 on the test card 19, it calls the corresponding preprocessing process to start running.

[0078] Select the sample to be tested, add 10 ml of diluent, compact and break the sample, extract the supernatant, and use the pipetting mechanism 4 to take out 4 ml and 3 ml respectively and add them to sample bottle No. 1 and sample bottle No. 2. Use the transfer mechanism 8 to cover the sample bottle cap.

[0079] The transfer mechanism 8 places sample vials 1 and 2 into shaker 12 and shakes for 4 minutes, then places them into centrifuge 11 and centrifuges for 3 minutes, and then places them into sliding rack 2 6.

[0080] Slide the slide holder 2 6 and add quantitative reagent A and reagent B to sample bottle 1 respectively through pipetting mechanism 4. Use shaker 12 to shake and mix well, then place in incubator 10. Then use sampling needle to draw the test solution from sample bottle 1 and drop it onto the corresponding lead and cadmium detection card 19; draw the test solution from sample bottle 2 and drop it onto the corresponding detection card 19.

[0081] After sequential testing, the test card 19 is ejected on the right side of the instrument. Combined with the QR code 20, the relevant curves are retrieved, the results are automatically calculated, and displayed on the control panel 18 screen. The results can be transmitted to the "Food Safety Data Management and Analysis System" to monitor quality and safety.

[0082] After the test is completed, the cleaning waste liquid is placed in the waste liquid tank. During cleaning, the cleaning liquid is added by taking out the cleaning liquid bottle 22, which makes it convenient to add cleaning liquid in time. The cleaning liquid is extracted by the pipetting mechanism 4, and the instruments of each unit are automatically cleaned. The waste liquid is then extracted into the waste liquid tank 15.

[0086] Insert the combined test card 19 into the tester 9 in sequence. After the tester 9 recognizes the QR code 20 on the test card 19, it calls the corresponding preprocessing process to start running.

[0087] Place the sample to be tested into the sample bottle, compact and break it up, extract 1g of sample into sample bottle No. 1, and add 4ml of extraction solution;

[0088] The sample vial No. 1 is placed into the shaker 12 and shaken for 5 minutes using the transfer mechanism 8, then left to stand for 5 minutes.
