Computing Overrun (cont.)
3)Draw a heaping cup of frozen product that contains no air pockets. Note: Use a spatula or other device to help fill the cup completely. Avoid tamping the cup as this artificially reduces overrun.
4)Use a straight edge to scrape off excess product flush with the rim of the cup and weigh the cup.
5)Subtract the cup weight and use the overrun formula to determine overrun.
Weight ofWeight of
Liquid Mix (Minus) Frozen Product x 100 = OVERRUN
Weight of Frozen Product
For Example:
If a full cup of liquid mix weighs 23 ounces (.652kg) and a full cup of frozen product weighs 15 1/2 ounces (.439kg), then:
15 1/2
Note: Several companies manufacture scales that automatically read out the overrun for
Overrun has a major impact on the size of the finished frozen portion. As the percentage of overrun (air in the frozen product) increases, the size of the finished portion also increases, yet the portion weight remains the same. For example, an increase from 25% to 50% overrun will yield a 20% larger portion. Customers equate size with perceived value so proper overrun will result in increased customer satisfaction. Experiment with carburetor settings to achieve optimum overrun and product quality with each mix. Some products such as Cappuccino taste better with low overrun. Experiment with different carburetor settings to find the ideal combination for each product.

IMPORTANT: The
Mix Low Function
This model will sense when the mix is low in the hopper. The mix low light will illuminate continuously for 2 min- utes. After 2 minutes the light will begin to blink off and on for the next 8 minutes. The buzzer in the mix out circuit is 2 minutes off and 5 seconds (or 5 beeps) on for a total of 10 minutes.
