Commercial shippers of perishables often use dry ice even for non frozen goods. Dry ice gives more than twice the cooling energy per pound of weight and three times the cooling energy per volume than regular water ice (H2O). It is often mixed with regular ice to save shipping weight and extend the cooling energy of water ice. Sometimes dry ice is made on the spot from liquid CO2. The resulting dry ice snow is packed in the top of a shipping container offering extended cooling without electrical refrigeration equipment and connections.
Isogenix Dry Ice only use Food Grade quality CO2 to produce our superior product.
Dry Ice comes in different forms:
- Solid Blocks
- Nuggets (Pellets)
- Rice Nuggets (Pellets)
Dry Ice should be used as soon as bought or kept in a well insulated cooler. Dry Ice will "sublimate" at a rate of approximately 4.5 kilograms every 24 hours. A 23.5 kilogram block is sufficient to keep food frozen, in a cooler, for about 6-7 days. You will need to purchase Dry Ice as close to when you plan to use it as possible, as Dry Ice will not keep. Dry Ice starts "sublimating" as soon as it's manufactured.
How do you use Dry Ice?
For keeping material frozen, place the Dry Ice in the cooler on top of the frozen material (as cold goes down). Close the lid and do not open until necessary to minimize loss. Dry Ice will not harm frozen food
DRY ICE PELLETS
THE FAST, LOW COST, EASILY CONTROLLED REFRIGERANT
Dry Ice Nuggets offer important new economies in handling and shipping. They lower the cost of lowering temperature. Really fast temperature reduction, more precise temperature control and uniform cold distribution assures thorough, even refrigeration. Labor is significantly reduced. Handling and crushing of Dry Ice Blocks is eliminated.
Uniformly sized Nuggets provide effective cooling. Their dense structure lasts longer and transfers heat at an ideal rate.
Rice Nuggets are used in Dry Ice Blast cleaning.
