The ideal holding temperature for frozen desserts is –10°C / 14°F. A freezer’s ability to freeze at that temperature or lower isn’t the only requirement demanded from it. During a busy service, the freezer door will be opened and shut many times, trapping the outside temperature with it. The compressor should be powerful enough to restore the temperature to –10°C / 14°F quickly so as to not affect the frozen product. Stabilizers cannot do the work alone to prevent heat shock. Proper air circulation is another contributing factor to the quality of the freezer. The better the air flow, the more consistent the temperature will be, even with constant opening and closing of the freezer door.
