11 Soft Serve Information
11.1 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
translates to a volume increase of 50
percent — 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 per-
form the following steps:
1. Place an empty pint container on
the scale* and adjust your scale to zero.
2. Remove container from scale
and fill the container with liquid product
to the top. Weigh container and record.
3. Replace liquid product with
frozen product, being sure to leave no
voids or air spaces in the container.
4. Strike off the excess product so
it is even with the top of the container
and measure the weight.
5. Use the following formula to
figure overrun percentage:
“Weight of liquid mix minus weight of
frozen product/divided by the frozen
weight. Multiply by 100.” See example.
Example:
Weight of half liter of mix = 510 g
Weight of half = 340 g
liter of frozen product
Difference = 170 g
170 g divided by 340 g = .5
.5 x 100 = 50% overrun
*Your Electro Freeze Distributor can
provide a scale (P/N 158049) that is
graduated in overrun percentage.
If local health codes permit the use of
rerun make sure to follow these proce-
dures:
1. Store rerun mix in a clean,
sanitized container.
2. Store in a cooler with a tempera-
ture below 4.4 º C.
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.
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.
For further information contact your local
Electro Freeze distributor or the Service
Department of H. C. Duke & Son, Inc.,
phone (309) 755-4553.
