Study on heat transfer characteristics and gas flow in propane air fryer
Air fryer is a leading cooking tool for kitchen innovation,proposed a calculation method of mass and heat transfer in a propane air fryer,the law of heat transfer and air flow in an air fryer with air return structure was studied,a calculation model considering steady-state heat transfer and fluid dynamics was established and the influence of three-dimensional structure of air fryer on internal temperature and fluid velocity was analyzed.The analysis shows that the temperature of the heating plate is transmitted to the air,and the temperature is transmitted to the food through the air flow.In the velocity field analysis,the velocity distribution diagram of different sections is shown,the influence of the inlet on the air velocity is clarified,and the change of the direction and velocity of the air flow with the spatial position is shown.The temperature heat transfer and air flow inside the air fryer are deeply analyzed,compared with experiments,it was found that the air fryer with an air recirculation structure has higher cooking efficiency and better quality for food,which provides important reference and theoretical support for optimizing the design and improvement of the air fryer.
