To determine the relationship between the ice amount of packing for transportation of pasteurized milk and the temperature in the foam box and the transportation time under a certain external temperature, and to obtain the appropriate ice amount data. Considering the influencing factors of foam box ice aviation logistics and the actual operation mode, the energy consumption model of foam box ice transportation was established, and the energy consumption balance process was analyzed. On this basis, the ice amount of foam box ice transportation was set as different standards, and the corresponding relationship between the logistics duration and the temperature in the foam box was studied under different external temperatures and 50%~20% ice amount. The relationship curve between the ice proportion and the low temperature time in the foam box, the arrival time of the lowest temperature in the box, and the transportation time under the appropriate temperature was made. Research suggests that the ice amount of 50% can meet all the usual external temperatures within 60 hours of transportation quality. The logistics duration is less than or equal to 24 hours, the recommended ice amount is about 20%. The logistics duration is about 36 hours, the recommended ice amount is about 30%. The logistics duration is about 48 hours, the recommended ice amount is not more than 40%.
为了确定巴氏奶运输中包装冰的用量与泡沫箱内温度和在一定外界温度下运输时间之间的关系，并获得合适的冰用量数据。考虑到泡沫箱冰航空物流的影响因素和实际操作模式，建立了泡沫箱冰运输的能耗模型，并对能耗平衡过程进行了分析。在此基础上，将泡沫箱冰运输的冰量设定为不同的标准，并研究了不同外界温度和 50%~20%冰量下，物流持续时间与泡沫箱内温度之间的关系。制作了冰比例与泡沫箱内低温时间、箱内最低温度到达时间和适宜温度下运输时间之间的关系曲线。研究表明，在运输质量 60 小时内，50%的冰量可以满足所有常见的外界温度。物流持续时间小于或等于 24 小时，建议的冰量约为 20%。物流持续时间约为 36 小时，建议的冰量约为 30%。物流持续时间约为 48 小时，建议的冰量不超过 40%。
