How to Put Ice Cream in an Ultra Low Temperature Freezer
Ice cream is among the most popular frozen treats in the world, and its dairy base makes it among the most difficult to store properly --- any amount of thawing and refreezing can result in taste imperfections and biological contamination. One particularly effective way to avoid refreezing problems is through use of an ultra low temperature refrigerator, which stores the ice cream at a temperature between -40 and -86 degrees Fahrenheit.

Place your ice cream in a container that is suitable for your freezer's storage temperature. Most plastic storage devices are suitable for ultra low temperature storage. If you're not sure what containers to use, refer to your freezer's user's manual for information about recommended storage devices and how to purchase them. Never place a glass container in an ultra low temperature freezer, as doing so will cause the glass to break.
