1. Use a suitable cooler
Dry ice is not like regular ice; it is carbon dioxide (CO2), frozen below 109°F. Consequently, when heated, carbon dioxide does not melt, but instead sublimes and releases CO2.
It is important to use a refrigerator with adequate ventilation and insulation to prevent CO2 from building up pressure and exploding inside the refrigerator. Dry ice needs to be handled with extra care and if you don't have a suitable cooler we recommend using itother methods of cooling foodinstead of.
For regular campers, we recommend investing in one of these quality coolers:
- Tundra Yeti.Available in three sizes (35, 45 and 65) perfect for camping, fishing and other adventures. The Tundra 45 holds 28 cans of beer including ice.
- Yeti Roadie. Smaller than the Tundra and better suited for road trips. Only available in one size and large enough for wine bottles.
2. Consider using two coolers
If you're camping in a group of four or more, a cooler probably won't provide enough storage space. While one fridge should suffice for two people, consider using two fridges if space allows.
The advantage of two coolers is that one can be used as a freezer to store dry ice and regular ice, while the second cooler is used for food and beverages.
Take regular ice from the first cooler to put in the second as needed. Using coolers in this way slows the sublimation of dry ice and eliminates the risk of food freezing.
3. Buy the right amount of dry ice
You don't want to overfill the cooler with ice, but you also don't want your food heating up in the middle of camp. Knowing exactly how much dry ice you need allows you to use your cold storage effectively and keep your food fresh at all times.
As a general guide you will need double the amount of ice cream/drinking or a 2:1 ratio of ice cream/drinking. This keeps your food and drinks cold during your trip.
4. Freeze your food ahead of time.
It's a good idea to freeze any food you intend to eat about two days before your trip. By freezing food ahead of time, you keep refrigerator temperatures down, which slows dry ice sublimation.
The added benefit of freezing ahead of time is that it helps you stay organized and gives you plenty of time to buy more drinks if needed.
5. Make sure you wear protective gloves
Dry ice is very, very cold! So cold that you can seriously burn your hands if you're not careful. When handling dry ice, it is important to wear protective gloves, e.g. B. Insulated rubber gloves.
Have burn ointment ready in case you burn yourself. Dry ice burns are treated like regular burns. Wash the burned area with warm water and, if necessary, treat it with burn ointment. In the case of severe frostbite or burns with a risk of infection, consult a doctor.
6. Wrap the dry ice in brown paper
Wrapping the dry ice in newspaper or brown paper serves two purposes. First, it insulates the dry ice and slows down the sublimation process. Secondly, newspapers protect against frost in case you accidentally touch them.
Two to three sheets of newspaper will do, but you can add more. If you plan to place the dry ice on the bottom of the cooler, you can wrap it thick enough to fill the entire surface and minimize air gaps.
7. Create a barrier between the dry ice and your food.
Of course you want your food to be cold, but frozen food is not edible. To avoid frozen food, you should avoid direct contact between your food and dry ice.
While the newspapers around the dry ice will help a little, they won't do the trick. A towel folded in half makes a great tampon and keeps food from freezing. You can use the towel to clean the cool box at the end of the journey, so two stones!
8. Place the ice on the top or bottom of the cooler
Many people put dry ice on the bottom of the refrigerator as it is more convenient and reduces the risk of accidental burns when handling dry ice.
Placing dry ice on top will keep your produce fresher longer as the cold air descends. However, you will have to deal with ice more often. Choose what works best for you.
9. Strategically pack your food and ice in your cooler
To keep food and dry ice cold longer, open the fridge as little as possible. Pack the goods you will use last or least often at the bottom to avoid taking out everything for that item next.
If you must take out food for lunch, take out as much as you need at one time to keep opening and closing to a minimum.
10. Minimize air gaps by using newspaper
The less air there is in your cooler, the slower the dry ice will sublimate, keeping your food fresh and your journey comfortable.
Effective use of space when packing minimizes most gaps. For any other airspace left over after packing, you can use crumpled or brown newspaper.
11. Keep your fridge in a cool place.
Quality coolers like Yeti coolers will keep your produce cool even in full sun, but a cool spot helps. If you keep your cool box in a shady place, the contents stay cool much longer! After all, the sun is a heat source.
You can create a shaded area with a tarp or netting, or even place the cooler inside your tent when there is no shade.
12. Dispose of dry ice safely
When you need to dispose of dry ice, it's important to do it properly and safely. Carbon dioxide poisoning is not something to be taken lightly!
The easiest way to get rid of dry ice is to leave it outside so you can sublimate it. You must watch it to make sure no children or animals touch the ice before it sublimates. If you can't leave it outside, put it in a well-ventilated area.
