3. Replace liquid mix 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 weigh.
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 ½ liter of liquid mix
Weight of ½ liter frozen product = 340 g
Difference
170g divided by 340 g
.5 x 100 = 50% overrun
*Your Electro Freeze Distributor can provide
a scale (P/N 158049) 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.

local Electro Freeze distributor or the
Service Department of H. C. Duke &
Son, Inc., phone (309) 755-4553.
