Abstract
The transient temperature computational model of the change of food temperature was set up. With the established model the influence rule of various heat transfer modes such as conduction, radiation and convection on the temperature of food in different storage conditions was analyzed. The results showed that the temperature distribution of each position of the display cabinet was different. The results showed that the temperature near the air curtain air supply outlet was the lowest and the temperature on the bottom of the front position was the highest. Secondly, the effects of different heat transfer modes on food temperature were different, and the weight size was conduction > radiation > convection. So strengthening the heat conduction ability of the shelf could rapidly reduce the food temperature. Thirdly, the cooling time at different locations was different, and the location near the air curtain air supply output of the fastest temperature decline could be used to place easily spoiled food. This model can be used to predict the cooling rule of food package and provide reference for the best food cold storage.
