When we think of keeping perishables cold, we typically imagine ice-packs and pounds of bagged ice in big plastic coolers. While they sometimes may keep our food cool and fresh, they all often end up the same way: a big leaky or soggy mess with nothing quite as cold as we would like it to be. Enter dry ice! Dry ice can be utilized for a variety of uses, from commercial applications like cleaning equipment or cooling asphalt to consumer uses like decoration for the holidays or keeping food cold when camping. If you’re wondering how dry ice can work for your products, it’s best to understand exactly how it works in general.
What is Dry Ice?
Dry ice is frozen carbon dioxide. Carbon dioxide has a much lower freezing point than regular water and is therefore much colder, at about -109.3 F. As it gets warmer, instead of melting into a puddle like regular ice, dry ice sublimates directly into carbon dioxide gas. This is great for shipping frozen items, especially over long distances, because the item will still be frozen, but also dry.
How is it Made?
To make dry ice, you need liquid carbon dioxide in a high-pressure container and slowly release that carbon dioxide. The liquid carbon dioxide will expand and evaporate at high speed which cools the remaining liquid to the freezing point where it then becomes a solid. You can see this happening in a carbon-dioxide fire extinguisher when snow forms in the nozzle–if you compress that snow you create a block of dry ice.
How Can You Use It?
There are a lot of uses for dry ice, and if you need it for your products, there are many ways to utilize dry ice for preservation or shipping. From medical supplies to seafood, if you need to ship your products, dry ice is a great solution for keeping your products frozen for shipping around the world. If you’re in construction, you can use dry ice in metal fabrication to shrink worked metal for a tight fit or to cool concrete and asphalt when you’re on deadline. If you work in an industrial setting, you can also use dry ice to clean your equipment without disassembling it; this is called dry ice blasting.
