柜外环境对立式冷藏陈列柜食品温度影响的研究

Study on the Influence of the External Environment of Vertical Refrigerated Display Cabinet on the Food Temperature

本文研究了环境温度、湿度及灯光照度相互之间对立式敞开式冷藏陈列柜食品温度的影响,以期为降低食品冷藏温度和提高冷藏食品的品质提供依据。实验发现立式敞开式冷藏陈列柜柜外环境温度、湿度以及灯光辐射对柜内食品温度的影响很大。随着柜外环境温度、湿度的升高,柜内食品的温度逐渐升高;随着柜外灯光照射强度的增加,柜内食品温度也逐渐升高,且当灯光强度达到一定程度时,增加少量的灯光都会对食品温度产生较大的影响,即降低环境温湿度及灯光照度有利于降低柜内食品温度,能较好保持好冷藏食品的品质,并且在较低湿度下运行,可以节省陈列柜能耗。

The influences of environmental temperature, humidity and light intensity of vertical open-refrigerated food display cabinet on the food temperature were studied. The results showed that the food temperature gradually rose with the increase of the environmental temperature, humidity and the light intensity. When the light intensity was raised to a certain level, a small extra increase in the light intensity may greatly influence the food temperature. So, lowering the environmental temperature, humidity and lighting intensity could decrease the temperature of the frozen food, maintain their qualities, and save the energy consumption of the food display cabinet.
