    便携式微型保鲜冷库研究

    Research and development of portable mini cold storage room

    • 摘要: 可折叠、便携式新型微型冷库研究,以新型聚乙烯基发泡材料为试材,以经典硬质聚苯乙烯泡沫保温材料为对照,明确便携式微型保鲜冷库的热功性能及其苹果、葡萄的保鲜效果。结果表明,便携式微型保鲜冷库的最佳制冷设备工作时间系数为0.24,对照0.32,库体导热系数为0.95,对照1.00。尺寸受热变形率-3.5%,压缩率7%,延伸率150%,压缩强度3.14 N/cm2,使富士苹果和巨峰葡萄的保鲜效果显著地优于对照。

       

      Abstract: To study portable mini cold storage room, the property of new type foamed polyethylene and the application of portable mini cold storage room made of this material in the storage of apple and table grape were studied comprehensively. The results show that comprehensive technical indexes of the structure made of foamed polyethylene board were good. The optimal coefficient of work hour of refrigerate system is 0.24, while that of the control is 0.32. The thermal conductivity of structure made of polyethylene and the control is 0.95 and 1.00, respectively. The property of foamed polyethylene board is as follows: the heat induced rate of shape change is 3.5%; compressed rate is 7%; expansion rate is 150%; compressed intensity is 3.14 N/cm2. The fruits of Fuji apples and Kyoho table grapes had better quality in the portable mini cold storage room made of new type foamed polyethylene than that in the control after 86 days' storage.
