Investigations on the Heat Transfer Model in Food during Microwave Heating

Microwave heating is a rapid and convenient strategy for food-reheating.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.
