Dry Ice Uses: Food Storage and Shipping
Discover How Dry Ice Can Aid in Food Transportation and Storage
Preserving Dry Goods with Dry Ice
Dry ice is highly effective in preserving dry goods like grains and legumes for an extended period. It's crucial to ensure that your storage container is suitable for dry ice and the dry ice doesn't contain any frost, which might introduce unwanted moisture. The process is simple: place the dry ice at the bottom of the container and pour your dry goods on top. Be cautious not to immediately seal the lid, as the sublimating dry ice could create a hazardous pressure buildup.
Within about 5-6 hours, the dry ice will have sublimated entirely, replacing all the oxygen in the container with carbon dioxide. This is when you can securely fasten the lid. Your food will now be safe from spoilage for an extended period. The absence of oxygen eliminates the threat from insects and bacteria, ensuring your food's longevity and freshness.
Cold Food Storage and Shipping with Dry Ice, Of course, dry ice also comes in handy for cold and frozen food storage. In situations like power outages or during outdoor activities like hunting or fishing trips, dry ice is a reliable solution to keep your perishables cold.
The CO2 gas that results from sublimation is denser than our atmospheric air, causing it to sink. Hence, it's optimal to place dry ice on top of items that need to be kept frozen and underneath food that needs to be cool. This method also proves useful when shipping items that must remain frozen.
Essential Dry Ice Facts To better understand the versatility and effectiveness of dry ice.
- Dry ice doesn't change from solid to liquid; it directly sublimates into gas.
- It is also known as cardice and is solid carbon dioxide.
- Dry ice is extremely cold, significantly colder than wet ice.
- The precise temperature of dry ice is -78.5 degrees Celsius or -109.3 degrees Fahrenheit.
- Dry ice is usually sold in the form of pellets or blocks.
- It has low thermal and electrical conductivity.
- Dry ice sinks in water and other fluids straight to the bottom.
- During sublimation, the released white vapor contains carbon dioxide, but most of it is water fog.
- It is best used in places where mechanical cooling isn't available.
- Dry ice should always be handled in a well-ventilated area due to the increased presence of CO2.

Dry ice (frozen carbon dioxide) is extremely cold and can cause skin burns upon contact. It is essential to wear protective gloves while handling it. Additionally, dry ice transforms into carbon dioxide gas upon evaporation, which is the desired outcome. Although CO2 is not inherently hazardous (as we exhale it with every breath), it is crucial to ensure proper ventilation in the area where you are packing your storage containers.
