How do they keep it longer than i can at my house? a 5lb block is gone with in 30 hours, but yet, at the store, a 5 pound block has been in there for a while.Bystander said:They don't.
Bystander said:The store runs its refrigerators at a lower temperature.
Dry ice sublimates at 194.65 K (−78.5 °C; −109.3 °F), at Earth atmospheric pressures. This extreme cold makes the solid dangerous to handle without protection due to burns caused by freezing (frostbite). While generally not very toxic, the outgassing from it can cause hypercapnia (abnormally elevated carbon dioxide levels in the blood) due to buildup in confined locations.
Thats a good read. I have red it in the past. I was just curious how my walmart stores it and what type of machine they use. Next time I am there, ill take a peek at itBystander said:
It will keep your freezer nice and cold.LT72884 said:so your saying the cooler that they store the dry ice in is a powered refrigerator, like a meat freezer? thus keeping it longer? So if i put in a deep freezer, with no other food, would that be ok then?
Well, you can handle it as the dry ice does not conduct heat very well. Just don't put it down someone's back as a stupid joke, or squeeze a chunk in your fist.Klystron said:Leading to this.
I didn't know Walmart or any other retailer had dry ice for sale to the public. We usually has to buy the bags from the "dry ice company". My guess is that they buy it in bulk every week and just store it some out of the place area.LT72884 said:Thats a good read. I have red it in the past.

Stores keep dry ice from evaporating by storing it in insulated containers or using specialized freezers that maintain a temperature of -109.3°F (-78.5°C). This helps to slow down the sublimation process, in which dry ice transforms from a solid into a gas.
Dry ice can be stored for up to 24 hours without evaporating if it is kept in an insulated container or specialized freezer. However, the exact amount of time can vary depending on factors such as the quantity of dry ice and the temperature of the storage environment.
Yes, dry ice can evaporate at room temperature. This is because the sublimation process will occur at any temperature above -109.3°F (-78.5°C). However, the rate of evaporation will be faster at warmer temperatures.
To transport dry ice without it evaporating, ensure that it is stored in an insulated container or specialized freezer. If possible, also try to limit the amount of time the dry ice is exposed to warmer temperatures during transport. It is also important to follow safety precautions, such as using gloves and handling the dry ice with care to avoid contact with skin.
If dry ice is left out at room temperature, it will eventually evaporate into carbon dioxide gas. This process is called sublimation and it occurs at a rate of about 5-10 pounds of dry ice per day at room temperature. It is important to handle dry ice with care and not leave it out for extended periods of time to avoid potential hazards.
