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.
If local health codes permit the use of rerun
make sure to follow these procedures:
1. Store rerun mix in a clean, sani-
tized container.
2. Store in a cooler with a temperature
º º
below 40 F (4.4 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.
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.
