What Makes Dry Ice Ideal for Freezing?
Dry ice, the solid form of carbon dioxide, is an extremely effective freezing agent thanks to its extremely low temperature of -109.3°F (-78.5°C). Unlike regular ice, which melts into water, dry ice sublimates directly into gas, which means it doesn’t leave behind any liquid. This makes it an excellent choice for keeping items frozen, whether you’re transporting perishable food, storing frozen goods for an extended period, or using it for specific freezing applications.
But just how effective is dry ice at freezing things? The simple answer is: very. Dry ice can keep food and other items frozen solid for extended periods, depending on how it’s used and stored. Whether you’re shipping frozen foods across the country or keeping things frozen at a remote location, dry ice’s ability to maintain freezing temperatures makes it a superior alternative to traditional ice.
In this article, we’ll explore various uses of dry ice for freezing and answer common questions like “will dry ice keep food frozen?” and “can dry ice freeze water?” We’ll also introduce our handy calculator tool to help you determine exactly how much dry ice you need for your freezing needs.
Will Dry Ice Keep Food Frozen?
How Dry Ice Maintains Freezing Temperatures
When it comes to keeping food frozen, dry ice is an excellent solution. Because dry ice is much colder than regular ice, it can maintain freezing temperatures for much longer. Dry ice will keep food frozen as long as it’s properly packed and stored in an insulated cooler or container. The cold air generated by the dry ice spreads throughout the cooler, ensuring that your food remains frozen during transportation or storage.
One of the key benefits of using dry ice is that it sublimates, which means it goes from a solid state directly to gas without leaving any liquid behind. This is especially helpful when transporting food that should not be exposed to moisture, such as meat, dairy products, or certain baked goods. With dry ice, you won’t have to worry about the water from melting ice contaminating or soaking your food items.
Best Practices for Using Dry Ice to Keep Food Frozen
To get the most out of dry ice when freezing food, it’s important to follow a few best practices. First, make sure you pack the food tightly in the cooler to minimize any air gaps, which can cause uneven cooling. Place the dry ice blocks on top of the food for the most effective freezing, as cold air sinks. For larger items or longer trips, layering the dry ice and food can help maintain freezing temperatures over a longer period.
How long dry ice will keep food frozen depends on several factors, including the size of the cooler, how much dry ice you use, and the external temperature. On average, dry ice can keep food frozen for 18 to 24 hours, but this time frame can be extended by using more dry ice or a high-quality dry ice cooler from Sub Zero Dry Ice.
To help calculate exactly how much dry ice you’ll need, use our dedicated dry ice calculator tool, which factors in the volume of items you’re freezing and the duration of time they need to remain frozen. This is especially helpful for large shipments or multi-day trips where precise calculations are essential.
Can Dry Ice Freeze Water?
One common question people ask is, “can dry ice freeze water?” The answer is yes. Because dry ice has an extremely low temperature of -109.3°F (-78.5°C), it can freeze water very quickly. If you place dry ice in a container of water, the dry ice will rapidly lower the water’s temperature, freezing it in a fraction of the time it would take using regular ice.
However, the way dry ice works is a little different from traditional freezing methods. Dry ice sublimates, meaning it transitions directly from a solid to a gas, skipping the liquid phase entirely. When placed in water, the dry ice will start sublimating immediately, and as the cold air spreads through the water, it begins to freeze. This process creates fascinating visual effects, as the water seems to freeze almost instantaneously, and fog-like vapor rises from the surface, making it an exciting experiment to try at home.
Fun Experiments with Freezing Water Using Dry Ice
If you’re looking to have some fun with dry ice, freezing water is a simple yet fascinating experiment. You can use dry ice to create ice sculptures, freeze water in various shapes, or even make ice cubes much faster than with a traditional freezer. By placing small pieces of dry ice into ice cube trays filled with water, you can create frozen cubes in minutes, all while producing cool fog effects that make the process fun to watch.
Another interesting experiment is to create “instant ice.” Start by chilling a bottle of water in the freezer until it’s just below freezing but still in liquid form. Then, place dry ice next to the bottle and pour the water out onto a surface. The water will instantly freeze into solid ice due to the rapid temperature drop caused by the dry ice. This is a great way to demonstrate how dry ice can freeze water quickly and make learning about freezing temperatures more engaging.
Does Dry Ice Freeze Other Things?
Dry ice isn’t just effective at freezing water — it can also freeze other materials quickly and efficiently. Whether it’s liquids like juice or solids like food items, dry ice is capable of lowering temperatures fast enough to freeze them solid. In fact, dry ice is often used in commercial applications to freeze large quantities of items, such as perishable goods, in preparation for transportation or storage.
Dry ice can also freeze delicate or temperature-sensitive items without damaging them. For example, if you need to preserve medical supplies or biological samples, dry ice offers a reliable freezing solution. Its ability to maintain sub-zero temperatures for extended periods makes it ideal for freezing items that require long-lasting cold storage.
Practical Uses of Dry Ice for Freezing
There are many practical uses for dry ice when it comes to freezing, especially in commercial and industrial settings. For instance, dry ice is commonly used to keep food and beverages frozen during transport, ensuring that items remain at safe temperatures throughout the journey. Companies that ship frozen goods, such as seafood, ice cream, or meat, often rely on dry ice to maintain product quality during long trips.
Additionally, dry ice is used in the medical field to preserve organs, tissues, and other biological samples that require freezing. It’s also used in laboratories and for scientific research when freezing needs to occur quickly and efficiently. Dry ice’s ability to freeze various materials, from liquids to solids, makes it a versatile and reliable freezing agent in both everyday and specialized applications.

Safety Tips for Using Dry Ice for Freezing
Handling Dry Ice Safely
When using dry ice for freezing, it’s important to handle it with care to avoid injury. Dry ice is extremely cold and can cause frostbite if it comes into direct contact with your skin. Always use thick, insulated gloves, such as dry ice gloves, when handling dry ice to protect your hands. Avoid touching dry ice with bare hands and use tools like tongs to move or pack the dry ice in your cooler or container.
Additionally, dry ice releases carbon dioxide gas as it sublimates, so it’s important to use it in well-ventilated areas to avoid the buildup of CO2. When storing dry ice in a cooler, make sure the cooler is not completely sealed. Leaving a small vent or opening allows the gas to escape safely without creating pressure inside the cooler.
Storing and Disposing of Dry Ice Safely
When storing dry ice for freezing purposes, always keep it in a well-ventilated area to avoid the buildup of carbon dioxide gas. If you’re using a cooler, make sure there is a small gap or vent to allow the gas to escape. Never store dry ice in an airtight container, as the pressure from the gas can cause the container to burst.
If you have leftover dry ice after using it for freezing, dispose of it safely by allowing it to sublimate in a well-ventilated area. Do not throw dry ice in the trash or flush it down the sink, as it can damage plumbing and create hazardous situations. By leaving the dry ice in an open space, it will naturally turn into gas and dissipate without leaving any harmful residue behind.
