Description

Technical Field

[0001] The utility model relates to the technical field of food detection devices, specifically referring to a test tube oscillation device for food detection. Background Art

[0002] Food detection plays a crucial role in ensuring food safety. By conducting various tests on food, it is possible to promptly detect harmful substances, microbial contamination, and whether the nutritional components meet the standards in food, effectively safeguarding the health of consumers. Food detection encompasses multiple links, including sample collection, pretreatment, and analysis and detection. In these links, test tubes are often used to mix and react reagents.

[0003] During the food detection process, test tube oscillation is a commonly used operation method. It can fully mix the samples and reagents in the test tube, accelerate the reaction speed, and improve the accuracy and reliability of the detection. By oscillating the test tube, the components in the sample can be more evenly distributed in the reagent for better subsequent detection and analysis.

[0004] Traditional test tube oscillation equipment is usually of a fixed height and cannot adapt to test tubes of different heights. In actual detection, since different detection items may require test tubes of different specifications, and traditional equipment cannot be adjusted according to the height of the test tube, it brings many inconveniences to the detection work.

[0005] Traditional test tube oscillation equipment generally drives the entire test tube rack to shake, and this method will generate relatively large noise during operation. Summary of the Utility Model
