摘　　要：食品热杀菌过程中,存在冷点温度的测量、食品杀菌强度(F值)的计算较为困难,以及热源不稳定造成杀菌釜实际温度偏离控制温度的问题。本文开发了一种可实时计算食品中心杀菌强度并由此对杀菌釜的运行参数进行智能纠偏控制的系统。该系统主要包括实时F值计算部分和纠偏控制部分,适用于不同型号的杀菌釜,并自主开发了配套PC软件。验证试验表明,该系统可根据杀菌釜温度计算食品的中心温度,与实际值的偏差约3.12%。同时,实现了依据设定杀菌强度对热杀菌过程进行纠偏控制,最终获得的杀菌强度与设定值偏差为5.5%,满足工程应用的要求。In the process of heat sterilization,there are problems in measuring the cold spot temperature and the sterilization intensity of the food,and the problem that the actual temperature of the sterilization retort deviates from the control temperature due to the instability of the heat source.This paper developed a device that could display the sterilization intensity of food centers in real time and thus intelligently corrected the control temperature.The device mainly included real-time F value calculation part and correction part,which was suitable for different types of sterilization retorts,and supportive PC software was developed.The experiment showed that the deviation of the food center temperature and the value calculated by the device according to the temperature of the sterilization retort was about 3.12%,and the deviation could be corrected according to the set sterilization value.The deviation between the sterilization value and the set value was 5.5%,which could meet the engineering application.
