| 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. |
