摘　　要：针对现有热处理验证设备不能满足烹饪过程动力学函数成熟值M和过热值O测定需求,因而研制了一种能在计算机上实现多路自动采集烹饪温度、积分计算M/O值的数据采集分析系统。该系统采用超细铠装热电偶作为温度传感器,使得系统温度采集精确度达到±0.05℃;系统采用辛普森法积分计算M/O值并具备智能实时显示、记录并存储数据的功能。系统应用实例中测定了样品的表面和中心温度、表面和中心成熟值、表面和中心过热值,其中M/O值测量误差分别为±1.16%和±0.58%。应用表明,所研系统满足了成熟值理论的验证与分析、烹饪试验传热学和动力学试验以及烹饪过程的数值模拟试验等研究的设备需求。The process characteristics of typical Chinese cuisine were analyzed into heat transfer, mass transfer,relative motion, and quality changes of fluid-particulate system in an open container, which showed that a temperature change of the heat transfer process played a crucial role in food quality. The current research object is to study the relationship between heat transfer and food quality of a fluid-particulate system by kinetics that is the bond of them. Based on aforementioned analysis, the primary purpose of cuisine is to make food materials mature and control heating which is the key to minimize food quality degradation while materials of cuisine are heated until done. In order to exactly express the degree of maturing in variations of temperature, Chinese cuisine maturity theory puts forward the novel kinetics functions in which maturity value（M value） and overheated value（O value） quantitatively expresses the degree of maturing and quality deterioration of foods respectively. Each of them was physically defined based on the equivalent heating time to reference temperature for respective quality factors. Validation and analysis of Chinese cuisine maturity theory, experiments of heat transfer and kinetics research on cuisine, and numerical simulation of the cuisine process all require basic test equipments to acquire data of heat transfer and kinetics of experiment. The existing instruments for validation of thermal process don＇t meet the requirements of the research of Chinese cuisine.Consequently, a system of data acquisition and analysis of heat transfer and kinetics for Chinese cuisine which automatically acquires temperature data in the process of heat transfer by multi-channels temperature acquisition module and simultaneously displays time-temperature profile, M value and O value of the integral computation of Simpson method that was programmed by Visual Basic software on the computer was developed.In the process of typical Chinese cuisine such as stir-frying, mixtures of fluid-particulate s
