Keep Ice cream frozen with dry ice
Dry ice is commonly used for temporary refrigeration. It is a solid form of carbon dioxide which is -109.3°F, colder than our home freezer. We recommend storing dry ice in a ventilated area & keep it away from children. Wear gloves before handling.
Thing we need
- Dry ice
- A towel/ Newspaper
Preparing dry ice
Collect enough dry ice according to your cooler size. You need about 10-20 pounds for a regular-size ice chest. You can also make your own dry ice by using a CO2 fire extinguisher. It could be dangerous, we don’t suggest doing that.
Covering the dry ice
At first, wear protective gloves to avoid cold. You can use a towel or newspaper to cover the dry ice. Covering ice will protect your ice cream or other food from extreme cold power.
Placing dry ice into the cooler
Depending on the foods you will carry on the cooler, you can put the dry ice on the top or bottom. To keep items frozen longer, put the dry ice on the top. Since cold air sinks, it works best on the top. Always try to put ice cream in the bottom and put dry ice above them.
Filling the gap
If there are any gaps in the cooler, use towel to fill them. Empty space will cause the dry ice to melt quickly.
Useful tips to keep food frozen longer on a cooler
- Close the cooler lid carefully.
- Avoid direct sunlight in the cooler.
- If you carry in a car, close the windows to reduce the sun’s heat.
Disposal of dry ice
When you’re finished using the dry ice, just keep your cooler open in a ventilated place. Dry ice will sublimate into carbon dioxide gas. It will dissipate into the air.
Keep ice cream frozen in a cooler without dry ice
Dry ice is very effective to keep ice cream frozen for longer. We can do this without dry ice. We will use regular ice that can be made using a freezer. Let’s do it.
Things we need
- Deep freezer
- Plastic container
- A serrated knife
- Warm water
- A towel/ Newspaper
- Safety Glove
- Few freezer bags
Making ice with a freezer
Take a plastic container and pour it with 4-5L water. Now, freeze warm water in a freezer for 18 to 24 hours. We have to wait until every inch of the water has frozen. When water turns into ice properly, use a serrated knife to cut the ice into cubes. Wear a glove before starting the cutting process.
We have to use a high-quality insulated cooler. Different types of coolers are available in the market. Insulate cooler works better than a disposable styrofoam cooler. Now cool down your cooler to reduce melting ice. Take enough time to make your cooler cool down. When the cooler is ready, follow the next steps.
Putting ice on the cooler
Now, pour the cooler with the ice. Keep ice cream on the bottom which needs to stay frozen. Then put a few cubes of ice above the ice cream. If you have something else, put them on the top of the cooler. Which we put in the bottom will stay cold longer.
Using rock salt & a freezer bag
Rock salt slows down the melting process of the ice. Use a few rock salt on the top of the rice.
Freezer bags also helps to slow down the melting process. It adds an extra layer of insulation. If possible, keep your foods in the freezer bag, then place them in your cooler.
Filling empty space
Use a towel to feel the empty space of your cooler to reduce the melting. Also, avoid opening your cooler without necessary and keep it shut as much as possible. Don’t keep your cooler in direct sunlight.
