食品微波加热过程中的传热模型

摘要

Microwave heating is a rapid and convenient strategy for food梤eheating. However, the phenomenon of uneven heating often occurs during microwave heating. To solve the "cold spot" problem during microwave reheating, a heat transfer model to predict the distribution of heat could help control the quality of food during microwave heating. Therefore, this manuscript summarized the recent advances in microwave heat transfer model, discussed the numerical calculation, theory and microwave absorption frequency of microwave heat transfer model, and analyzed the current issues and future development in this field.%微波加热是一种快速简便的食品复热手段,但此种方法通常会导致受热不均匀.为了更好的将微波加热技术应用于食品的复热过程,解决受热过程“冷点”的出现,作者综述了食品微波加热过程传热模型的研究进展,并针对数值计算方法、模型理论和功率吸收进行了详细阐述,探讨了微波能在食品中转化成热能的机制,并分析了研究过程中存在的问题和发展方向.
