FACEPLATE RELIEF VAL VES

The faceplate relief valves, located in each freeze cylinder faceplate (see Figure 3), are spring-loaded valves
that protect the freeze cylinders from accidental over-pressure. The relief valve is also used to manually bleed
CO2 gas from the freeze cylinder to atmosphere during filling with product and if gas pockets form in the cylin­der during operation.

DISPENSING VALVES

Self-closing dispensing valves, located on the faceplates on front of the Unit (see Figure 3), are operated one at
a time or simultaneously to deliver product to the customer.

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 CO2 gas

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, CO2 gas in the system takes a ‘‘set’’.
When the first few drinks are drawn off after an idle period, the CO2 gas has less tendency to break out as the
drink is dispensed. The result is these casual drinks have less overrun than drinks dispensed during the peakĆ

use periods.

DRAWING 1

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
the 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.

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 the overrun. After these factors have been
considered, desired viscosity (product consistency) adjustment may be made on the Unit. The viscosity adjust-

ment 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 ab-

sorb carbonation and the way it will release carbonation.

DRAWING 2

DRAWING 3

BRIX Affects Overrun.

Sugar in carbonated drinks is like antifreeze 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.

3120300029

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’’.

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 the freezing cycle and the amount of CO
present in the product combine to create the drink dispensed. The dispensed product will have a normal vari­ance due to the following conditions:

1. If some time has elapsed since the last drink was drawn from a particular freeze cylinder and the compres­sor has not cycled on, the drink dispensed will have a tendency to be wetter, have slightly less overrun
than normal for the setting, and will not mound up as high. See Drawing 1.

NOTE: A cylinder freeze-up may be expected under casual draw conditions if an attempt is made to
eliminate the drink described above by adjusting viscosity.

2. If product is drawn from the freeze cylinder quite regularly, its viscosity (product consistency) will be main­tained at whatever viscosity setting was made within the normal variance of the compressor off and on
cycle. See Drawing 2.

2

3. If product is drawn continuously from the freeze cylinder and the rate is approaching capacity of the dis­pensing Unit, overrun of the drink will increase just prior to point capacity is exceeded, and drink dispensed
will turn slightly wetter (see Drawing 3).
