Before setting the temperature on your commercial freezer, you should know what it is for. You might think the temperature is set in degrees Fahrenheit, but that’s not always the case. It is better to set the temperature to -18 degrees Celsius. To get the best performance from your commercial freezer, the temperature must be maintained between 0 and -18 degrees Celsius. To ensure your freezer is working properly, make sure the gasket around the freezer is not damaged or torn. If your seals are broken, air cannot flow through the freezer.
A commercial freezer should be set to a constant temperature lower than that of a refrigerator. Any temperature swing will destroy many items, from frozen meat to ice cream. If you store food at too high or too low a temperature, it will spoil quickly, and if you leave it for too long, freezer burn can occur. This is why choosing a quality commercial freezer is crucial.
If you plan to store ice in your freezer, consider the temperatures for the unit. A good rule of thumb is that ice cream freezes at a temperature of minus 10 degrees Fahrenheit or -18 degrees Celsius. However, if you’re selling ice cream, the ideal temperature for a commercial freezer should be minus 20 degrees Fahrenheit. Otherwise the ice won’t freeze. To avoid the risk of spoiling your produce, make sure your staff understands the temperatures for your commercial freezer.
