果箱堆码间距对其码垛区域内气流组织的影响

冷库是现代冷藏的主要设备,冷库内果箱不同的堆码方式会对冷库码垛区域内气流组织和温度场造成影响,从而直接影响果蔬产品等的储存.为探究冷库中果箱在不同水平间距下码垛区域内温度场的变化规律,通过做实验,分别在间距为0、1、2、3、4、5、6 cm的工况下对果箱之间间隙的进、出口截面以及中间截面的温度进行了测量和分析.结果表明...

Effects of the Stacking Spacing of Fruit Boxes on Air Distribution in the Stacking Area

Cold storage is the main equipment of modern cold storage. The different stacking methods of fruit boxes in the cold storage will affect the air distribution in the stacking area and the temperature field, which directly affect the storage of fruits and vegetables. In order to explore the law of the temperature change in the stacking area built by the fruit boxes in the cold storage under different horizontal spacing. The temperature of the inlet section and outlet section and the middle section of gap between the fruit boxes in seven working conditions with spacing of 0 cm, 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm were measured and studied by doing experiments. The results show that when the horizontal spacing between the fruit boxes is 1cm to 4cm, the temperature field between the fruit boxes is evenly distributed and have a good heat exchange effect. When the distance continues to be expended after more than 4 cm, the heat transfer effect of the overall air flow field is not affected. When the spacing is 2 cm, the precooling effect of apples is better, and then continue to increase the spacing has little effect on the precooling effect of apples. It is concluded that the horizontal spacing of fruit boxes of 1 cm to 4 cm is a suitable stacking spacing for fruit boxes in cold storage.
