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. Untuk menyimpan es kering, gunakan kotak penyimpanan khusus. Kotak penyimpanan yang baik dapat mengurangi kehilangan es kering hingga 6‰. Jika tidak ada kotak khusus, Anda juga bisa menggunakan kotak busa biasa untuk menyimpan es kering. Jika tidak perlu, usahakan untuk tidak memotong seluruh bagian es kering menjadi potongan-potongan kecil atau butiran. Hal ini karena es kering yang dipotong kecil-kecil akan lebih mudah menyublim dibandingkan es kering utuh.
  3. Es kering menguap dengan cepat, sebagian besar disebabkan oleh suhu tinggi. Oleh karena itu, Anda tidak dapat meletakkan es kering di tempat yang bersuhu tinggi, dan usahakan menyimpan produk es kering di lingkungan yang sejuk dan berventilasi. Ini aman dan memungkinkan es kering tetap didinginkan lebih lama dan tidak mudah meleleh.
  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.
