Dry ice is solidified CO2, its melting point is -78.5 ℃, and the surrounding temperature will be reduced to about 20 ℃ when it is volatilized. Therefore, it is easy to sublimate in daily storage, which causes dry ice to become smaller and cause losses. Therefore, a special dry ice storage box must be used for dry ice storage and transportation, which can effectively reduce the loss caused by the volatilization of dry ice.
What should be noticed when transporting with dry ice?
- If possible, it is recommended to store dry ice in an environment below -80 ° C and to store it with other items as little as possible. When using closed items such as dry ice storage boxes, leave a gap in the storage box. This is because dry ice is extremely volatile. If it is a closed environment, a large amount of CO2 generated by volatilization will be accumulated in the closed environment, which will cause the internal air pressure to rise continuously and there is a danger of explosion.
- 要储存干冰，请使用特殊的储存盒。一个好的储存盒可以将干冰损失减少到6‰。如果没有专用盒子，也可以使用普通泡沫盒来存放干冰。 如无必要，尽量不要将整块干冰切成小块或颗粒。这是因为切成小块的干冰比整块干冰更容易升华。
- 干冰蒸发很快，主要是由于高温。因此，不能将干冰放置在高温的地方，尽量将干冰产品存放在阴凉通风的环境中。这既安全又可以让干冰保持冷藏更长时间并且不易融化。
- Usually, when we transport seafood, we need to put dry ice around the seafood so that the seafood stays fresh for a long time. When choosing dry ice, it is best to use block-shaped dry ice cubes. The dry ice cubes will keep the seafood longer cooling effect during transportation.
