Dry Ice has a number of commercial and consumer uses:
- To remove floor tiles
- For low-temperature testing
- In the baking industry
- To make fog in the entertainment
- In the poultry industry
- To keep party kegs cold
- To improve porosity in oil wells
- By airline caterers to keep food chilled
- By blood banks for shipping
- To blast clean rubber and plastic injection molds and food processing equipment
- By the concrete industry to prevent heat buildup
- To freeze unstable ground
- To germinate food
- To blast clean fire-damaged buildings
- To remove skin imperfections
- As a mosquito attractant for traps
- To lengthens the life of wet ice
- To shrink metal
- To retard chemical catalysts
- To pack ice cream on trips
- To purge fuel tanks
- To brand animals
- To store food during power outages
- To pack trophy game or fish on the way home
- To freeze water lines without shutoff valves
Technical InformationDry ice, ''solid carbon dioxide,'' is a translucent substance. It has a density of approximately 97.6 lb./cu. ft. at atmospheric pressure. Blocks are cut to 50 lbs. each and measure about 10 x 10 x 12 in. The temperature of dry ice at atmospheric pressure is 109 degrees below 0 (141 degrees colder than water ice). The extremely low temperature accounts for its extensive use as a refrigerant. The extremely low temperature accounts for its extensive use as a refrigerant. One of its biggest uses as a refrigerant is to prevent foods from perishing.
It is used in trucks and rail cars, where mechanical refrigeration is not available, to preserve meats and frozen foods during transfer to market. Perhaps that greatest advantage, though, is that dry ice sublimes to CO2 gas rather than melt to water. Dry ice is non-toxic. Bottling companies use carbon dioxide to carbonate soda pop. However, if left in an unvented area such as a car, dry ice displaces the air. Therefore, if you leave a child or a pet in a car with dry ice, leave a window open. > When handling dry ice, always use leather palmed work gloves or even ski gloves.
The low temperature could cause frostbite if not handled properly. Do not seal dry ice tightly in unvented containers like bottles or thermoses. The dry ice will build up pressure when it ''melts." Keep dry ice away from children just as you would anything that would burn them. Using dry ice for camping will free you from having to make the daily trip to the market for fresh meat and allow you to keep ice cream, popsicles and ice cubes frozen at your own camp site. Dry ice will not harm food. Just wrap it as you would if putting it in your freezer at home.
In a Coleman or similar cooler, 1 block (50 lbs.) will last about 7 days depending on the condition of the cooler and how often it is opened. Loss is approximately 10% per day. It is important to remember that any product in the container is going to freeze solid. Do not leave bottles, milk or similar products in with the dry ice. Meat that has been packed with dry ice must be defrosted, as if from a freezer.
