Dry ice is solid carbon dioxide with a freezing point of -78°C (-109°F). It is extensively used for package deliveries of frozen dairy products such as ice cream. It is cut into pieces of appropriate size, which are wrapped in paper to avoid rapid evaporation and then placed around the package of the ice cream inside an insulated packer or in a single service type packer.

Because the ice is cold (sub-zero) but never gets wet when it melts as it sublimates (see earlier question) turning directly from a solid to a gas without ever becoming a liquid.

Dry ice is solid carbon dioxide gas. It's called dry ice because when it 'melts' it changes in state from a solid directly to a gas without ever becoming a liquid. This process is called sublimation. When dry ice is put into boiling water it sublimates and creates these clouds of thick heavy fog which clings to the ground (because it is cold and more dense than air).

Dry ice evaporates, so there may not be any visible dry in the package upon opening. If the food is cool to the touch the food is OK.

Yes! Using only 1.5 to 2.5 pounds (0.68 to 1.14 kg) of pellets per minute, Cold Jet's single-hose pellet blasting systems can clean two to five times faster than a two-hose block dry ice shaver system. The single-hose system has superior cleaning capability and can significantly reduce production downtime and correspondingly yield thousands of dollars in production savings beyond what is attainable with a two-hose block dry ice system.

No. It is not worth the risk & it does not last any longer than regular block ice. The following is an article of information regarding the use of Dry Ice: Normal air is 78% Nitrogen, 21% Oxygen and only 0.035% Carbon Dioxide. If the concentration of carbon dioxide (The Chemical Composition of Dry Ice) in the air rises above 0.5%, carbon dioxide can become dangerous. Smaller concentrations can cause quicker breathing but is otherwise not harmful.

Dry ice blasting is similar to sand blasting, bead blasting, or soda blasting where a media is accelerated in a pressurized air stream (or other inert gas) to impact the surface to be cleaned.

Dry ice pellets are delivered to your plant in sealed insulated containers. Depending on the climate, the pellets will last in their container for 5 to 12 days. Once the seal is broken, the ice should be used in 1 to 3 days.

Dry ice pellets are available all over the world. In the United States, call +1-800-SEND-ICE (+1-800-736-3423) or +1-513-831-3211 for a location near you.

To ensure that your product arrives frozen we ship with 5lbs. of dry ice. In most instances, the dry ice will have evaporated or partially evaporated by the time you receive the product. However, if your box does contain some dry ice, do not touch the ice with your bare hands. Use tongs, insulated (thick) gloves or an oven mitt and dispose of the ice outside. Do not let dry ice evaporate in your home or in a confined space. Crack windows open if the ice remains in your home for a period of time.

If Dry ice is the ONLY hazard, the package must be labeled with a Class 9 label along with the net weight of the dry ice within the package. No Dangerous Goods Declaration Form is required but the dry ice must be declared on the courier's airway bill in accordance with the company's requirements, which may or may not also include documenting the net weight of the dry ice.
