新型食品级保温罐式集装箱的研发与应用

Development and Application of New Food-grade Thermal Insulation Tank Container

针对传统食品级罐式集装箱保温性能较差,运输时间受限的问题,研发了新型食品级保温罐式集装箱。新型罐式集装箱采用聚氨酯高压整体发泡工艺,在保证抗压强度的条件下,导热系数约为传统岩棉罐式集装箱的一半。此外通过为保温罐式集装箱加装专用制冷机组,可进一步控制罐内货物温度,适用于跨洋远途运输,实现多式联运。实际运行结果表明新型食品级保温罐式集装箱可以有效延长运输时间,满足使用需求。

Aiming at the problems of poor thermal insulation performance of traditional food-grade tank containers and limited transportation time,a new type of food-grade thermal insulation tank container has been developed.The new tank container uses polyurethane high-pressure integral foaming process.Under the condition of ensuring compressive strength,the thermal conductivity is about half that of the traditional rock wool tank container.In addition,by installing a special refrigeration unit for the tank container,the temperature of the cargo in the tank can be further controlled,which is suitable for long-distance transportation across the ocean and realizes multimodal transport.The actual operation results show that the new food-grade insulated tank container can effectively extend the transportation time and meet the demand for use.
