Abstract

Abstract: Forced convection oven as a common baking tool, the uniformity of temperature field is an important index to measure its performance. Through the study of the uniformity of the temperature field of a dual fan convection oven, finds that: (1) Using Teflon blocks to simulate food, the variance of simulation is in good agreement with the experimental range, which can be used to reflect the temperature field uniformity of cavity; (2) Compared with the uniformity of temperature field of single fan cavity, the clockwise rotation of dual fans can increase about 30%; (3) In the dual fan cavity, left fan rotates clockwise and right fan rotates counterclockwise, the heating rate of the center of the cavity is increased by 17% compared with dual fans rotate clockwise. In addition, when left fan rotates clockwise and right fan rotates counterclockwise, the heat accumulation in the center area of the cavity can accelerate the cooking of large-volume food.
