Description

Technical Field

[0001] The present invention relates to the technical field of microbial detection, and particularly to a rapid detection device for food inspection and detection of microorganisms. Background Technique

[0002] Food microbiological detection is a detection method that uses the theory and methods of microbiology to detect the types, quantities, properties of microorganisms in food and their impact on human health, so as to determine whether the food meets the quality standards. At present, the food microbiological indicators include total colony count, Escherichia coli and pathogenic bacteria. The microbiological detection procedure includes sample collection, sample submission, sample processing, inspection and result reporting. When inspecting samples, to avoid contamination of the test samples, it is necessary to carry out the inspection in a sterile environment. After diluting the samples, they are placed in a culture medium. After culturing for a certain period of time, the total colony count and distribution in the culture medium are often observed under a microscope.

[0003] At present, when the existing food microbiological detection is carried out, it is often necessary to take multiple samples of the same food or multiple foods for inspection. After the existing food microbiological detection device finishes detecting one sample, it is necessary to manually remove the loading tray and then replace it with a new loading tray before placing the sample on the loading tray to detect the next sample. This detection method not only has a low working efficiency, but also the hands will inevitably touch the food samples when replacing the loading tray, and it is extremely easy to cause contamination when replacing the next loading tray, resulting in chaos during detection and contamination of the samples, leading to errors in detection. Therefore, there are certain deficiencies. For this reason, we have proposed a rapid detection device for food inspection and detection of microorganisms. Summary of the Invention

The microscope 44 cooperates with the loading tray 13. The adjustment frame 43 can adjust the angle of the microscope 44 to facilitate its detection.

[0027] In summary, when using the rapid microbial detection device for food inspection and testing, first place the sample to be tested into the interior of 47. Subsequently, screw 48 onto the top of 47 to seal it. Inject hydrogen peroxide into the interior of 46 in advance through 68. Then, combine 46 and 47. When combining, insert 59 into 46 through 57. The hydrogen peroxide located inside 46 will flow into the interior of 47 along 60 and mix and soak with the sample. At this time, place 19 into the interior of 18. The heating structure inside 18 can be used to heat and digest the mixed sample, thereby performing wet ashing treatment. Subsequently, place the disinfected loading tray 13 into the storage tray cylinder 27 from the top of the storage tray cylinder 27. After the loading tray 13 is placed into the storage tray cylinder 27, the positioning rod 29 at its bottom is inserted into the guide groove 31 for positioning. Then, activate the multi-joint electric telescopic rod 36 to push the slider 35 to slide and drive the pull plate 42 to move through the second connecting plate 40 at the same time. While the pull plate 42 is moving, the loading tray 13 at the bottommost part of the bottom of the storage tray cylinder 27 is pulled towards the guide cylinder 32. Subsequently, the loading tray 13 is conveyed to above the positioning head 12 through the guide cylinder 32 and the installation of the loading tray 13 is completed by inserting the positioning rod 29 into the installation hole 30. Then, activate the servo motor 5 through the controller to drive the disc 6 to rotate one circle. The dial rod 7 on the top of the disc 6 cooperates with the dial groove 8 to drive the positioning disc 4 and the rotating shaft 3 to rotate 60°. Repeat this process to move the loading tray 13 below the blanking port 25. Subsequently, insert the samples into the U-shaped groove 18 in sequence according to the detection order. During the heating process, 55 made of β-eucryptite has the characteristic of thermal contraction and cold expansion, so it no longer fits tightly with 49. Therefore, 55 at the bottom of 19 above 20 loses the bottom support and thus disengages from the interior of 49, causing the sample inside 47 to be injected onto 13 through 20 and the blanking port 25. Then, hold 67 and take out the 19 that has been fed with materials from the interior of 18 to make way for the samples to be tested subsequently. Finally, activate the servo motor 5 again to convey the loading tray 13 loaded with samples to the detection station through the above transmission method. While the rotating shaft 3 is rotating, it can drive the driven synchronous pulley 21, the first rotating rod 16, and the material distribution disc 17 to rotate through the driving synchronous pulley 23 and the synchronous belt 24, so that the next storage cylinder 19 loaded with the sample to be tested moves above the through hole 20 for convenient feeding and detection in the next time. After the sample is detected by the microscope 44, activate the servo motor 5 again to rotate the detected sample and the loading tray 13 to the inside of the mounting rack 14. Subsequently, the control panel energizes the electromagnet coil 39 to generate magnetic force and adsorb the loading tray 13. Then, activate the multi-joint electric telescopic rod 36 to push the slider 35 to slide and send the loading tray 13 above the collection box 52 through the electromagnet coil 39. Then, the control panel controls the electromagnet coil 39 to de-energize to place the loading tray 13 into the collection box 52 for collection. At the same time, while the slider 35 is sliding, it drives the pull plate 42 to move through the second connecting plate 40. While the pull plate 42 is moving, the loading tray 13 at the bottommost part of the bottom of the storage tray cylinder 27 is pulled towards the guide cylinder 32,Subsequently, the material loading tray 13 is conveyed above the positioning head 12 through the guide cylinder 32 and then inserted into the mounting hole 30 through the positioning rod 29, thus completing the replacement of the material loading tray 13. The overall use is convenient and fast, and the detection efficiency is high.
