Description

Technical Field

[0001] The present invention belongs to the technical field of food microorganism detection, and in particular relates to a food microorganism rapid detection device for food detection. Background Art

[0002] Food microbiological testing methods are an essential component of food quality management. Food microbiological testing is a key indicator of food hygiene quality and a scientific basis for determining whether a food is edible. The food microbiological testing process primarily includes pre-test preparation, sample pretreatment, microbiological testing, and result feedback. With the development of modern biotechnology, the types of testing equipment available for microbiological testing are increasing, making food hygiene microbiological testing more efficient and convenient.

[0003] To address this, Chinese Publication No. CN113686854A proposes a rapid food microbiology detection device for food testing. This device addresses the problem that manual food grinding often fails to achieve sufficient results and observation is relatively difficult. The device uses a first pad on the outer wall of the rotating grinding disc and a second pad in the mounting groove to further grind the debris, thereby ensuring more accurate microbial detection. However, the above technical solution and the existing microbial detector need to mix the sample with the detection liquid before testing during the detection process of food microorganisms. During the detection period, the food residue will be deposited in the detection liquid and then accumulate at the bottom of the culture container. The detector will be blocked to a certain extent during the irradiation detection process, thereby affecting the detection accuracy. In addition, for some solid foods, the staff needs to manually shake the detection container after mixing the detection liquid to ensure that the detection liquid and the solid food are fully mixed. In this process, the effect of manual vibration mixing is poor and increases the workload of the staff. In this regard, the present design proposes a rapid detection device for food microorganisms for food testing. Summary of the Invention
