Abstract: With the rapid development of the dairy industry,the quality and safety of dairy products have received much attention,and accurate and efficient detection technology has become the key.As the core equipment of modern dairy testing,the constant temperature and oscillation detection device integrates advanced temperature control and oscillation technology,which can simulate complex environment,ensure uniform heating and full reaction of samples,and provide accurate and reliable support for dairy testing. In this paper,the application of the device in dairy detection was discussed,including microorganism,nutrient composition,physical and chemical properties and pollutant detection.Its working principle,key technology and structure are described in detail. Comprehensive analysis of temperature control accuracy,oscillation performance,stability,sealing and other performance indicators.It also look forward to the future development trend from the aspects of innovative design, technology integration,standardization and intelligence,aiming to provide theoretical and technical support for improving the level of dairy testing and promoting the development of the industry.

Key words: constant temperature oscillation detection device, dairy testing, microbial detection, nutrient analysis, physical and chemical characteristics detection, pollutant detection, temperature control technology, oscillation technique, performance optimization
