Soft Serve Information

10.1 Overrun

As mix is frozen in the freezing cylinder,
air is incorporated into the mix to in-
crease its volume, as well as enhance
the taste and texture of the finished
product. The increase in volume is
called overrun. Fifty percent overrun
means a volume increase of 50% — 10
gallons of liquid mix has become 15
gallons of finished product.
Controlled overrun is important to
maintain consistency in product quality.
Too much overrun (air) results in a light,
fluffy product lacking the cold, refreshing
appeal of a quality product. Too little
overrun results in a wet, heavy product.
To correctly measure the overrun,
perform the following steps:
on the scale* and adjust your scale to
zero.
and fill with liquid product to the top.
