It is also possible to freeze food by immersion in the warmer (at −70 °C (−94 °F)), but cheaper, liquid carbon dioxide, which can be produced by mechanical freezing (see below). [ 8 ] Most frozen food is instead frozen using a mechanical process using the vapor-compression refrigeration technology similar to ordinary freezers .
They can be used as a normal reusable ice pack by storing in a freezer, but they can also be heated in water or a microwave oven to reach the desired temperature. The first hot and cold pack was introduced in 1948 with the name Hot-R-Cold-Pak and could be chilled in a refrigerator or heated in hot water. [ 3 ]
