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.
- ドライアイスを保管する場合は、専用の保管箱をご使用ください。優れた保管ボックスを使用すると、ドライアイスの損失を 6 パーセントに減らすことができます。特別な箱がない場合は、通常の発泡箱をドライアイスの保管に使用することもできます。 必要がない場合は、ドライアイス全体を小さな断片や顆粒に切らないようにしてください。これは、ドライアイスを丸ごと食べるよりも、細かく切ったドライアイスの方が昇華しやすいためです。
- ドライアイスは主に高温により急速に蒸発します。したがって、ドライアイスを高温の場所に置くことはできず、ドライアイス製品は涼しく換気の良い環境に保管するようにしてください。これは安全であり、ドライアイスをより長く冷蔵状態に保ち、簡単に溶けないようにすることができます。
- 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.
