Description

Technical Field

[0001] This invention relates to the field of food testing technology, and in particular to a rapid microbial detection device for food production. Background Technology

[0002] In the food production process, to ensure food safety, MBS microbial detection devices are usually used. MBS microbial detection devices are based on the physiological and metabolic characteristics of microorganisms and molecular recognition technology. They achieve high-sensitivity detection through the biochemical reaction between specific detection reagents and target pathogens. During food testing, operators need to inject a quantitative food sample and detection reagent into a special detection bottle. In order to ensure that the microorganisms in the sample come into full contact with the detection reagent and shorten the reaction time, the testing personnel usually need to shake the detection bottle several times before placing it into the detection tank.

[0003] For example, application number CN201210363941.2 discloses a rapid detection method and device for microbial samples, based on a mesoporous biochip. The method first involves immobilizing antibodies on the micropores of the mesoporous biochip. The test sample flows through these antibody-immobilized micropores, allowing the chip to separate and enrich pathogenic microorganisms or other biological substances. Then, a solution containing fluorescently labeled or enzyme-labeled antibodies is injected into the micropores, forming a sandwich-type antibody-antigen-labeled antibody immune complex. Pathogenic microorganisms or other biological substances are detected by measuring the fluorescence intensity of the fluorescently labeled antibody or the light absorption or chemiluminescence intensity of the enzyme-catalyzed reaction products. Because the mesoporous biochip has numerous micropores, significantly increasing the reaction area, this invention offers high sensitivity and rapid detection of microbial samples.

[0004] However, MBS microbial detection devices are usually equipped with multiple detection slots, requiring testing personnel to shake multiple test bottles in sequence. This not only increases the workload and frequency of repetitive work for testing personnel, but also affects the microbial cell breakage rate, reagent penetration uniformity, and detection efficiency of food due to differences in oscillation frequency, amplitude, and holding posture among testing personnel. Furthermore, it leads to inconsistent reaction conditions for multiple test samples, affecting the accuracy of the test results. Summary of the Invention

[0005] In view of this, the present invention provides a rapid microbial detection device for food production. During use, the simultaneous opening and closing of multiple light-shielding caps can be achieved simply by rotating the drive shaft. This not only reduces the workload of testing personnel and avoids repetitive tasks, but also improves the efficiency of food testing and enhances the ease of use in practical applications. Furthermore, the present invention utilizes the force exerted when the light-shielding caps are closed to synchronously drive the oscillation auxiliary mechanism, achieving synchronized shaking of multiple test bottles. This further reduces the workload of testing personnel, simplifies their operation, and avoids repetitive tasks. The frequency of shaking, while ensuring uniform penetration between microbial cell disruption and reagents, not only improves the efficiency of food testing but also guarantees the consistency of reaction conditions among multiple test samples, further enhancing the accuracy of test results and the speed of food testing, as well as the working efficiency and effectiveness of this testing device in practical applications. Furthermore, during the simultaneous shaking of multiple test bottles, the damping characteristics of the flexible buffer ring ensure that the impact energy is controlled while keeping the peak stress at the bottom of the test bottle below the glass transition temperature, avoiding the risk of container breakage and further improving the safety of this testing device in practical applications.
