摘 要:
目的与方法：降低冷藏陈列柜内冷藏食品的温度及提高食品冷藏品质；将超市里一般平行摆放食品的方式改为阶梯型，通过比较采用这2种陈列方式后是否能够降低食品内部温度以及降低幅度，来决定其试验的可行性和实用价值；结果：与水平型陈列方式相比，采用阶梯型陈列方式后，总体来说，各层搁板前后排食品温差均有所降低，第1、2层冷藏空间的食品温度下降幅度较大，具用一定的可行性；而对第3、4层冷藏空间来说，其效果不如前2层理想，有待于采用其它方式进行强化传热。[著者文摘]

Abstract:
Objective and methodLadder-type fodd display way is employed instead of parellel display. The two display ways affecting fodd tem- perature inside refrigerated display cabinet were compared. Conclusion： The results showed that food temperature difference among the front and back of a shelf was decreased ovrall after using ladder-type display way, as compared with parellel display way：food temperature in the frozen space of the first and second floor reduced; while that in the frozen space of the third and forth floor rose slightly,other method for enhancing heat transfer should be adopted.[著者文摘]
