9.2 Draining Product from Freezer
NOTE: It is your responsibility to be
aware of and conform to the requirements
for meeting local, state, and federal laws
concerning the frequency of cleaning and
sanitizing the freezer.
To remove frozen product from the
cylinder, perform the following steps:
1. Place a clean, sanitized
container under the dispensing nozzle.
2. Remove the mix feed tube from
the hopper. (See gure 9-3.
3. Turn the selector switch to the
“CLEAN” position.
4. Dispense the product until the
mix hopper is empty. Turn the selector
switch to “OFF” position and drain the
remaining product. Close the plunger. If
franchise and local health codes permit,
cover the rerun product container and
place in a cooler. (See 10.2 General
Information - Rerun).
5. Pour 2 gallons of cold water
into the hopper. Turn the selector switch
to “CLEAN” and dispense the cold water.
Important:
DO NOT use hot water. Damage to the
freezer could occur.
10. Place an empty container
under the dispensing head. Drain the
sanitizing solution from the cylinder by
slowly pulling down on the dispense
handle. Open and close the handle
several times while draining.
11. With most of the sanitizing
solution drained, turn the selector switch
to the “OFF” position and drain the
remaining sanitizer from the freezer and
close the plunger.
12. Proceed to disassembly,
cleaning and sanitizing instructions.

warm water and repeat until the freezer
dispenses clear water. With most of the
water dispensed, place selector switch
in the “OFF” position and drain the
remaining water.
7. Prepare sanitizing solution
in a container. Sanitizing solution must
be mixed according to manufacturer’s
instructions to yield 100 ppm available
chlorine solution.

10 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 nished 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 nished product.
Controlled overrun is important to
maintain consistency in product quality.
Too much overrun (air) results in a light,
uffy 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 ll with liquid mix to the top of
the contianer. Measure and record the
weight.
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 gure
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 = 18 oz.
Weight of one = 12 oz.
pint frozen product
Difference = 6 oz.
6.0 oz. divided by 12 oz. = .5
.5 x 100 = 50% overrun
* Your Electro Freeze Distributor can
provide a scale (P/N HC158049) that is
graduated in overrun percentage.
c. Remove the liquid mix and ll the
same container with frozen product. Be
sure there are no voids or air spaces in
the container.
10.2 Rerun
If local health codes and franchise 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 40ºF (4.4ºC).
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. Twice 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.,
