Product Information

10.1 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:
a. Place an empty pint container on
the scale* and adjust your scale to zero.
b. Remove the container from the
scale and fill with liquid mix. Measure and
record the weight.

10.2 Rerun

If local health codes permit the use
of rerun make sure to follow these
procedures:
1. Store rerun mix in a clean,
sanitized container.
2. Store in a cooler with a
temperature below 40
3. DO NOT prime the machine with
rerun. Always skim off and discard foam.
Then combine the rerun with fresh mix
in a ratio of 50/50 and add to the hopper
during operation.
4. Once a week run the mix as low
as possible and discard after closing. This
will break the rerun cycle and reduce the
possibility of high bacteria and coliform
counts.

c. Remove the liquid mix and fill the
same container with frozen product. Be
sure there are 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." See example.
Example:
Weight of one pint of mix =
Weight of one
pint frozen product
Difference
6.0 oz. divided by 12 oz.
.5 x 100 = 50% overrun
* Your Electro Freeze Distributor can
provide a scale (P/N HC158049) that is
graduated in overrun percentage.
NOTE: Rerun product is unable to
accept the same amount of air as fresh
product. As a result, the quality will
be affected and product may appear
grainy and icy.
