What to pay attention to when transporting with dry ice?

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?

  1. 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.
  2. Para almacenar hielo seco, utilice una caja de almacenamiento especial. Una buena caja de almacenamiento puede reducir la pérdida de hielo seco al 6 ‰. Si no hay una caja especial, también puedes utilizar cajas de espuma normales para almacenar hielo seco. Si no es necesario, trate de no cortar un trozo entero de hielo seco en trozos pequeños o gránulos. Esto se debe a que el hielo seco cortado en trozos más pequeños se sublimará más fácilmente que un trozo entero de hielo seco.
  3. El hielo seco se evapora rápidamente, principalmente debido a las altas temperaturas. Por lo tanto, no puede colocar hielo seco en un lugar con alta temperatura y trate de mantener los productos de hielo seco en un ambiente fresco y ventilado. Esto es seguro y permite que el hielo seco permanezca refrigerado por más tiempo y no se derrita fácilmente.
  4. 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.
