  • Page 14: Dispensed Product Conditions

    DISPENSED PRODUCT CONDITIONS ‘‘OVERRUN’’, AS APPLIED TO FROZEN CARBONATED BEVERAGES Overrun Defined. Overrun is product expansion that takes place in the frozen carbonated drink. It is caused primarily by CO breakout and secondary by freezing. Low Dispensing Volume Affects Overrun. When the Unit sits idle for a period of time and no drinks are dispensed, CO gas in the system takes a ‘‘set’’.

  • Page 15: Operating Characteristics

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

ADJUSTING BRIX (WATER-TO-SYRUP “RATIO”) OF DISPENSED PRODUCT BRIX is the Water-to-Syrup “Ratio” of the dispensed product and should be periodically checked and if neces- sary, be adjusted by a qualified Service Person.
