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
Weight of half
liter of frozen product
Difference
170 g 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.
