Product Quality

BRIX

Correct BRIX effects product flavor and freezing characteristics. Frozen product with low BRIX may have a weak fla- vor, larger ice crystals, and a tendency to dispense slowly. Product with high BRIX has an overly strong flavor, increased portion cost and results in lower freezer output capacity.

Alcohol Content

High alcohol content may prevent the freezer from serving product at proper thickness. High alcohol also suppress- es the syrups ability to absorb CO2 and depresses the temperature of the frozen product. Too much alcohol will also lower product overrun.

What Is Overrun?

Overrun is the increase in product volume, expressed as a percentage, resulting from the carbonation of the water. The freezer chamber is pressurized, which holds the carbonation in the frozen product. The carbonation causes the volume of the frozen product to increase when dispensed. For example, if one gallon (4.4 liters) of liquid mix is fed into a freezing cylinder and one and a half gallons (6.6 liters) of frozen product is drawn out, the result is a fifty per- cent volumetric increase, or a fifty percent (50%) "overrun".

Why is overrun important? The introduction of CO2 into the finished frozen product is essential from two stand- points...taste and profitability. Frozen product that has a low percentage of overrun costs more to serve, appears wet, and is heavy. The introduction of CO2 makes the finished frozen product taste richer. Too much overrun causes the finished frozen product to be too light and fluffy, making it less satisfying and adversely effecting sales.

Factors Effecting Overrun

Syrups

The foaming agent in the syrup increases the ability of the frozen product to expand as it is dispensed.

Frozen Product Draw Rate Effects Overrun

Infrequent frozen product usage can result in a drink that may appear wetter and have less overrun.

Carbonation In The Water Effects Overrun.

There is a direct correlation between the level of carbonation of the water and the overrun of the frozen drink. Water quality has a direct effect on carbonation. If it is difficult to achieve adequate overrun an activated carbon filter will have to be added to the system. Also try readjusting the carbonator CO2 pressure.

Computing Overrun

1)Weigh an empty cup.

2)Weigh this cup filled to the rim with liquid mix, and subtract the weight of the cup.

3)Draw a heaping cup of frozen product that contains no air pockets. Avoid tapping 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 of Frozen Mix Product

For Example:

If a full cup of liquid mix weighs 23 ounces (.652kg) and a full cup of frozen product weighs 15 ½ ounces (.439kg), then:

23 - 15½ X 100 = 48.4% Overrun 15½
