Dry ice (carbon dioxide ice) cools or freezes your products quickly. It can also be used to keep products cold or frozen. Dry ice is solid carbon dioxide which changes directly from solid into gas and evaporates without leaving a trace.
Dry ice can be used in a multitude of ways. During warm seasons, it is a great help in parties, since it can keep served foods and beverages properly cooled. It is also handy when defrosting the freezer. In addition to preserving food, dry ice can be used to keep served foods cold. It can also be used for decoration, for example for creating fog.The temperature of dry ice is very low, -78 ºC. As a result, properly insulated gloves must always be worn when handling dry ice. Never put dry ice in your mouth! The extreme coldness will cause severe frostbites as a result of rapid drop in temperature.
