中文摘要:
      目的 研究喷淋热杀菌过程中杀菌初始温度对PET瓶装饮料温度场分布的影响。方法 运用有限元分析软件Ansys构建喷淋热杀菌PET瓶装饮料热传导模型, 并以水为喷淋介质对其进行温度加载。结果 喷淋热杀菌过程中, PET瓶装饮料的温度场分布受杀菌初始温度影响较大, 但其高温区域始终位于瓶肩中心处。杀菌初始温度越高, 其最终温度场分布中高温区域所占比例越大, 最高温度值有所提高, 达到相同温度所需的时间也越短。结论 杀菌初始温度的适当提高可保证杀菌效果, 同时也可缩短杀菌时间。
英文摘要:
      This paper studied the effect of different initial temperatures on the temperature field in the spray sterilization process. This paper designed the heat conduction model of PET bottled drinks in the spray sterilization process with finite element analysis software ANSYS, which was loaded with temperature, taking water as the spray medium. The temperature distribution of PET bottled drinks was greatly influenced by the initial temperature in the spray heat sterilization process, but the high-temperature region was always located at the center of the bottle shoulder. The higher the initial temperature of PET bottled drinks was, the larger the proportion of the high temperature region in the final temperature field was and the greater the value of the maximum temperature was, besides the shorter the time it needed to reach to the same temperature. An appropriate increase of the initial temperature could guarantee the sterilization effect and shorten the sterilization time.
