Soft Serve Information

11.1 Overrun

As mix is frozen in the freezing cylinder,
air is incorporated into the mix to increase
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:
the scale* and adjust your scale to zero.
fill with liquid product to the top. Weigh
container and record.
* Your Electro Freeze Distributor can provide a scale and container (P/N HC158049)
that is graduated in overrun percentage.

a. Place an empty pint container on
b. Remove container from scale and
c. Replace liquid product with frozen
product, being sure to leave no voids or
air spaces in the container.
d. Strike off the excess product so it
is even with the top of the container and
measure the weight.
e. Use the following formula to figure
overrun percentage:
"Weight of liquid mix minus weight of
frozen product/divided by the frozen
weight."
Example:
Weight of one pint of liquid mix
18 oz.
Weight of one
pint frozen product
Difference
6.0 oz. divided by 12 oz.
.5 x 100 = 50% overrun

= 12 oz.
= 6 oz.
