Tips on how to keep your ice from melting too fast, how to keep your ice cold and your food fresh when traveling in the desert.
by Lynn Bremner of DesertUSA.com
One of the challenges of camping in the desert is keeping your ice from melting in a cooler and thus keeping your food and beverages cold and edible. How can you preserve your ice so it doesn’t melt quickly? Learn tips to keep your food from getting soggy from melted ice. Discover techniques to keep a cooler cold for 5 to 10 days if ice is not available for purchase nearby.
What type of cooler should you use?
There are many types of coolers to choose from, including metal, plastic, Styrofoam, soft-sided nylon and hard-sided plastic. The soft-sided nylon coolers and Styrofoam coolers are suitable for day trips. If you are camping overnight or going on a longer trip, it is very important to get a durable cooler that can keep your food and beverages cold over a period of time. Metal coolers hold heat longer when left in the sun, so plastic coolers are the most popular choice for campers.

When selecting a plastic or hard-sided cooler, make sure to choose a cooler that has an insulated lid with a tight seal. Wheels and big handles for easier management are also beneficial features. Make sure your cooler has a plug on the bottom for water drainage.
Pre-chill your drinks and food before placing the items in the cooler. You’ll extend the life of your ice by pre-chilling all items. You can also pre-chill your cooler by filling it with ice to chill the interior, prior to packing it with food and beverages.
Freeze plastic bottles of water or canned drinks that are not carbonated, such as Hansen’s fruit juices. The frozen drinks will act as ice and will keep the other items in your cooler colder. You can also freeze water or other non-carbonated beverages in gallon milk or juice jugs. They can be consumed when the liquid inside melts.
Freeze meat, and any other food that can be frozen, to help keep the food cold and fresh. Freeze bread and other food items that don’t require refrigeration, and store these items in a dry cooler without ice to keep food fresh and dry.
Line your cooler with Reflectix (aluminized bubble wrap). You can find it at most home improvement stores. It was invented to insulate homes and buildings. Smart campers came up with the idea to use Reflectix to keep the heat out and the cold air in coolers. Cut the Reflectix into pieces that fit, lining the inside of your cooler, including the top/lid. You can even throw a sheet of Reflectix over the outside of your cooler to further insulate it.
Packing your cooler
Pack items in your cooler in chronological order based on when you plan to use or consume the items. Put the items you will use last on the bottom of the cooler, and those you will need access to first, on top. Cold air travels down, so pack the items in the cooler first and then pack either crushed ice or block ice on top. Make sure you pack your cooler tight as air pockets can increase the temperature inside.
Pack perishables such as meat or dairy products directly on the ice. Put food in zip-lock plastic bags or in plastic containers to keep it dry as the ice melts.
For longer trips it’s a good idea to keep your beverages in a separate cooler that can be opened more frequently. Put all of your food in another cooler and open it less often.
What type of ice should you use? Crushed ice cools items faster, but ice blocks last longer. Block ice is recommended for trips that are more than one or two days. Dry ice will last the longest and keep your food dry, but requires some special handling.
You can freeze water in quart-sized zip-lock bags. They will work just like ice packs, but won’t leak water as they melt. In addition, the bags of water, once melted, can be refrozen and used again. As noted above, frozen water bottles, milk or juice jugs filled with water or juice can be used in place of, or with ice cubes or blocks. Frozen blue ice packs also work well in place of ice.
If you are going on a trip where you will not be able to purchase ice or where you need your cooler to stay cold for several days or weeks, consider dry ice. Dry ice comes in blocks wrapped in paper. Keep the paper on the dry ice or wrap it in newspaper or craft paper. Don’t pick up the dry ice with your bare hands. Use gloves or some sort of barrier between your skin and the dry ice as it will burn your skin.
Dry ice will crack a plastic cooler if it is sitting directly on the bottom of the cooler or touching the sides. The dry ice needs to be wrapped in paper (NOT plastic), and placed on a rack or barrier so it doesn’t crack your cooler. You can cut down a cheap Styrofoam cooler, place the dry ice in the bottom of the cut down portion, and then place that inside of the plastic cooler. This creates a barrier between the dry ice and the plastic sides and bottom of the cooler. You might also try putting a stainless steel dish rack with legs in the bottom of the cooler and then placing the dry ice on the rack. Stainless steel dish racks can be found in most stores that sell kitchenware.
Anything stored right next to dry ice will freeze. Keep this in mind when packing fruit, dairy products or other items that you don’t want to freeze. Dry ice does not melt, it sublimates and keeps items cold or frozen, and dry.
Another idea is to pack the dry ice in a separate cooler and surround it with frozen blue ice packs. Don’t put any food or beverages in this cooler, just the dry ice with frozen blue ice packs. Once the blue ice packs in your food or beverage cooler are used up, switch the blue ice packs with fresh ones out of the dry ice cooler. It’s a great way to refreeze your blue ice packs and avoid damage to your food by freezing it too much with dry ice.
Does Salt Keep Your Ice Colder?
Fact or fiction . . . does salt keep your ice colder? Well, kind of. Salt melts ice. When salt is mixed with water and ice together, it can bring the freezing temperature of the water to a lower degree, making the water colder without freezing it. What this means is that the combination of salt, ice and water creates really cold water. The down side is that salt also causes the ice to melt, and the goal of keeping your ice cold for a long period of time is to keep the ice from melting.
The ice/water/salt combo is s a great trick if you are having a party, run out of cold drinks and need to chill something quickly. Put some water in a big bucket or pot, put the canned beverages or bottled beverages into the container, add ice and salt to the water and stir the mixture. Put the container with the salt water mixture and the drinks in the freezer and those beverages will be chilled in a matter of minutes. Or keep the mixture out and spin the drinks in the fluid – that will also speed up the chilling process. If you don’t spin the beverages or put the mixture in the freezer it will still chill the drinks faster than ice alone or your refrigerator would without the ice/water/salt mixture.
During your trip . . .
Once you arrive at your camping location be sure to keep your coolers in the shade and out of the sun. You can put an old sleeping bag over them for further insulation. You can also use a tarp or Reflectix to keep the sun off the cooler. Ice will last twice as long when your cooler is placed in the shade.
Only open your coolers when necessary and when you do open the cooler, close it right away. Don’t drain the cold water from freshly melted ice out of the cooler, as the cold water helps keeps the items in the cooler cold. Drain the water only when necessary to create more space in the cooler or when adding more ice.
