Overrun

During the freezing process, mix is blended and
frozen with air. The frozen mix absorbs air and
therefore increases the volume of the mix.
Example: If 1 gallon of mix yields 1.5 gallons of
frozen product, the mix volume has been increased
by 50 percent. The overrun is then 50%.
Calculating Overrun
1. Place a cup on a scale and adjust the scale to
read "ZERO".
2. Fill the cup completely with unfrozen fresh mix
and weigh the cup of mix. Write down the
weight. Discard the liquid mix and rinse the cup.
3. After the freezer has completed a refrigeration
cycle, draw frozen product into the same cup.
As the cup fills, lightly pack the product to
prevent air pockets. Slightly overfill the cup and
then close the freezer draw valve.

4. Skim off the excess product at the brim of the
cup.
5. Place the cup of frozen product on the scale
and record the weight.
6. Divide the unfrozen fresh mix weight by the
frozen product weight. The answer indicates
the increase in volume.
