Dry ice is a solid form of carbon dioxide which can be used to keep food cold, as well as to provide a smoky effect for occasions such as parties. However, you will need to store it properly and handle it safely. Here are some tips on how to get the best out of your dry ice.
Use the container
The best container to use for dry ice is the one it was sold in. This is likely to be a styrofoam box that will be well insulated. You can add extra insulation if you wish by wrapping it in a towel. If you want to transfer it to something else, you will need to use another container with a high degree of insulation. Otherwise, the dry ice will suffer from sublimation and may have evaporated by the time you want it.
Keep it cold
Dry ice sublimates more quickly in higher temperatures. It is best stored in a freezer until it is needed. It is not suitable for storage in a fridge or a cold room for any period of time. When it is taken out of the freezer, it should not be placed on ordinary kitchen worktops or tiles - the freezing cold temperature of the dry ice container can damage or crack the surface.
Keep it well-ventilated
When the dry ice is removed from the freezer, you should ensure that it is stored in a well-ventilated area. The dry ice gives off carbon dioxide that can be hazardous to both human and animal health. If you are transporting the dry ice in a car or another vehicle, make sure you open the windows and take the ice directly to its destination - do not leave it in a parked vehicle. You should use the dry ice as soon as possible after buying it - preferably on the day of purchase.
Do not consume
Most importantly, make sure that no one swallows the dry ice. Although it can be added to drinks to cool them down and provide a striking smoke effect, it is best to do this with special safety containers to make sure there is no risk that anyone consumes the dry ice.
Dry ice adds an air of mystery to your event, or it can just be used as a coolant. Just talk to a supplier like Dry Ice WA about your requirements or if you have any questions.
