freezer (plural freezers) 1  An appliance or room used to store food or other perishable items at temperatures below 0Â° Celsius (32Â° Fahrenheit). 2  The section of a refrigerator used to store food or other perishable items at a temperature below 0Â° Celsius (32Â° Fahrenheit).
The temperature of your freezer is affected by how full your freezer is, how well you maintain it (keeping it from icing up) and the quality of your freezer. If your freezer is constantly at or below -18Â°C and the chicken was bought frozen tests have shown little measurable change at 12 months.
