How to keep dry ice cold?
Place the dry ice in an insulated container like a plastic cooler/ice chest. Since dry ice is much colder than traditional freezing containers (-109.3 degrees Fahrenheit which is -78.5 degrees Celsius), it won’t be kept cool by your average freezer or refrigerator.
How to slow down dry ice sublimation?
The thicker insulated your cooler or ice chest is, the slower the dry ice will sublimate. Open and close the container as little as possible to slow down the sublimation process. You can also fill the open space in the cooler with wadded paper to limit dead space and slow down sublimation as well.
What happens when you sublimate dry ice?
The sublimation of dry ice to carbon dioxide will cause the container to expand and possibly explode. Dry ice can cause a violent eruption if packed too tightly. Some people have been brought up on felony criminal charges for purposely confining dry ice until it explodes, creating a dry ice "bomb.".

If your skin blisters or comes off, treat the area with antibiotic ointment and wrap with a bandage. Consult a doctor immediately in cases of extreme burns.
What to wear when opening dry ice?
Wear leather gloves and long sleeves when opening or pouring dry ice. Though brief contact is harmless, prolonged contact with skin can freeze the cells and burn you in a manner similar to fire.
What is Dry Ice?
Dry ice is a super cooling agent with many practical uses—from keeping food and medical samples frozen to creating fog for concerts and Halloween parties.
When To Use Dry Ice
Since dry ice has an exceptionally cold temperature of minus 109.3 degrees Fahrenheit (minus 78.5 degrees Celsius), it’s best reserved for products that absolutely need to be kept very cold, such as frozen foods, sensitive medical supplies and some biologics.
Procuring Dry Ice
You can obtain dry ice from local dry ice suppliers, including some grocery and big box stores. It comes in different shapes and sizes, from pellets and big blocks to slices and little bullets, depending on your need. Dry ice is generally inexpensive, and the larger the quantity you buy, the lower the price per pound.
Handling Dry Ice
You have to be very careful when handling dry ice since its extreme cold temperature can cause physical harm. Handlers must wear goggles to protect eyes, special gloves to safeguard hands and bibs to ensure dry ice does not spill under clothes.
Storing Dry Ice
Special containers must be used when storing dry ice. Airtight containers cannot be used, as the process of sublimation can create severe internal pressure and cause the container to rupture or explode. Glass containers also cannot be used, as the glass can crack.
Calculating How Much Dry Ice To Use
As a rule of thumb, expect five to ten pounds of dry ice to sublimate every 24 hours. However, the exact sublimation rate will depend on the density of the expanded polystyrene (EPS) insulating foam container you use. The lower the density, the faster the sublimation. Factor this into your shipping calculation.
Packing With Dry Ice
Make sure your contents are at the optimal temperature when you’re ready to pack them. Use an EPS foam container for its insulating properties, and place it inside a sturdy, corrugated cardboard box.
What is Dry Ice?
Dry ice is another name for frozen carbon dioxide. This material, which freezes around -109 degrees F, is popular because its solid form sublimates directly into gas under normal atmospheric pressure, leaving behind no dampness. Since dry ice is simply carbon dioxide, it’s also non-toxic and, when scrubbed, safe around food. However, due to its low temperature, it can cause burns when it touches bare skin, and it should be handled in well-ventilated areas to avoid the danger of suffocation.
How is carbon dioxide turned into a solid?
The liquid carbon dioxide is turned into a solid through depressurization. CO 2 enters into a tank with normal atmospheric pressure through an expansion valve, which removes the liquid’s pressure to allow it to gasify again. As the gas expands, it drops the temperature inside the tank, freezing a little less than half of the carbon dioxide into a solid before it can become a gas. This 46% of the carbon dioxide becomes snow, condensing onto the upper plate of a press, which then compresses it for about five minutes under 60 tons of force to create a block. For dry ice pellets, the snow is extruded through dies in a pelletizer.
How does dry ice get its carbon?
Dry ice starts life as a byproduct; it’s harvested from the refining of ammonia, petroleum, or other chemicals. This gas is often taken from the ammonia production process, as that’s the most efficient way to produce carbon dioxide, but in the U.S. it’s also majorly supplied from the ethanol production process. Natural gas is burned to separate carbon and hydrogen atoms, and the hydrogen is then combined with nitrogen to make ammonia. The leftover carbon then can be mixed with oxygen to produce carbon dioxide.
What is the process of burning natural gas?
Natural gas is burned to separate carbon and hydrogen atoms, and the hydrogen is then combined with nitrogen to make ammonia. The leftover carbon then can be mixed with oxygen to produce carbon dioxide. Once harvested, carbon dioxide meant for contact with food is scrubbed to make it food grade.
What are pellets used for?
Pellets, which melt most quickly thanks to their high surface area, are used for frozen food, meat processing, laboratory experiments, and transportation of lab specimens and blood plasma. They’re also used by consumers and theater companies to create fog effects. Pellets come in a range of sizes.
How is dry ice pelletized?
For dry ice pellets, the snow is extruded through dies in a pelletizer. If the snow is compressed into block form, a two-foot-wide block then rolls out of the chamber on a conveyer belt. Pneumatic saws cut it to the required size from there.
What is dry ice production?
One type of dry ice production machine is known as a pelletizer, which produces, as its name suggests, dry ice pellets. Pelletizers are available in different sizes based on their production capacity which is typically measured in units of kg/hour or lbs/hour. The production capacity may also contain a specification for the inlet pressure …
What does the label on a dry ice container mean?
You will need a label that says "Dry Ice" or "Carbon Dioxide Solid.". You will need a label that reads UN 1845, which also indicates the package contains hazardous materials. You will need a label indicating the net worth of dry ice in your container. Make sure you know how much dry ice you used during packing.
How to keep food fresh?
Wrap the food in plastic wrap or place in paper bags prior to packing. You want to make sure the food and dry ice are packed together tightly. Use newspaper or cellulose to make sure it’s packed tight. This provides extra insulation, keeping your perishables fresh.
Why is dry ice dangerous?
Dry ice releases carbon dioxide, which can be hazardous if released through the package rupturing. A rupture can be caused by pressure pushed down on a package during shipments.

How to get dry ice out of your fridge?
Touch dry ice with bare skin. Lay dry ice directly on a solid-surface or tiled countertop —it could crack the surface. Expose unsealed food in your fridge directly to dry ice, which can freeze foods on contact. If flash-freezing items like fish, place food in a freezer bag or vacuum-seal it prior to dry ice exposure.
How long does it take for dry ice to sublimate?
