Overrun Overrun is the increase in product volume, expressed as a percentage, resulting from the entrapment of air in liquid mix as it is frozen. The rotating dasher blends air into the mix as it is frozen resulting in increased frozen product volume. For example, if one gallon (1) (4.4 liters) of liquid mix is poured into a freezer and one and a half gallons (1/2) (6.6 liters) of frozen product is drawn out, the result is a fifty percent volumetric increase, or a fifty (50%) percent “overrun”.
