Overrun is a Variable.

The percentage or degree of overrun depends on a number of factors. The specific syrup, BRIX, low dispensing volume, carbonation level in liquid product, and freezing, all affect overrun. After these factors have been considered, desired viscosity (product consistency) adjustment may be made on the Unit. The viscosity adjustment adjusts product texture from very wet to light.

Specific Product Ingredients Affect Overrun.

Each syrup has its own specific formulation of makeup. Baume, an important ingredient factor, may fall within an extremely wide range. Fruit flavors contain citric acids that colas do not. Colas also differ in ingredients from one brand to another. Each product formulation has its own peculiarities regarding the way the product will absorb carbonation and the way it will release carbonation.

BRIX Affects Overrun.

Sugar in carbonated drinks is like anti–freeze in water. The higher the BRIX in a product, the greater resistance the product has to freezing. Conversely, in products with lower BRIX, freezing takes place at higher temperatures than for high–BRIX products. Thus, BRIX affects overrun because the amount of sugar in a drink has a direct bearing on the product’s freezing characteristics.

Low Dispensing Volume Affects Overrun.

When Unit sits idle for a period of time and no drinks are dispensed, CO2 gas in the system takes a ‘‘set’’. When first few drinks are drawn off after an idle period, CO2 gas has less tendency to break out as drink is dispensed. The result is these casual drinks have less overrun than drinks dispensed during peak-use periods.

Carbonation Level in Liquid Product Affects Overrun.

The higher the specific carbonation level in a given product, the greater the potential for carbonation breakout in frozen carbonated form of that drink. For example, drinks with 3.0 volume of carbonation will have more gas breakout in frozen carbonated form, and more overrun, than will drinks that contain 2.0 volumes of CO2 gas.

Freezing Affects Overrun.

Freezing causes approximately a 10 percent expansion in dispensed frozen carbonated drink. The degree of freezing is limited because finished drink is intended to be sipped through a straw. This is not possible if product is too ‘‘solid’’.

OPERATING CHARACTERISTICS

The product viscosity (product consistency) can be varied by adjustment and secondary CO2 regulator setting from a high overrun light drink to a wet heavy drink. The length of freezing cycle and amount of CO2 present in product combine to create drink dispensed. The dispensed product will have a normal variance due to the following conditions:
