摘要(Abstract)：

以立式多搁架中温冷藏陈列柜为研究对象,研究空气预冷器对冷藏陈列柜所储食品温度的影响。试验结果表明:冷藏陈列柜使用减湿预冷器后柜内所储食品的平均温度降低了1.3℃,垂直方向上不同搁架区食品的平均温差降低了0.8℃,并且融霜时食品温度的回升也降低了0.8℃。因此,空气预冷器的使用,将有利于提高柜内所储食品的品质。
Using a mid-temperature multi-shelf vertical display cabinet,the effect of pre-cooler on food temperature in display cabinet was investigated.The results showed that: the average temperature of the food was lowered by 1.4℃,the temperature difference between the first shelf to the fifth shelf was lowered by 1.5℃,and the temperature rise during defrosting time was lowered by 0.8℃.And this new desing could lead to improvements in food quality.
