It will be necessary to brix your Wunder-Bar® Mechanical Flex Hose bar
dispenser before use. Either a Wunder-Bar® Syrup separator and Brix Cup
( Fig.5 ) or a refractometer may be used. Diet products do not contain sugar
and therefore diet products’ ratio may only be measured using a Brix Cup.
Brix ratio is the ratio of syrup concentrate to soda or water. A syrup separa-
tor (p/n PH10-83) is designed to separate the syrup/concentrate from the
soda or plain water, allowing for proper measurement of products. A Brix
Cup (p/n PH10-35) allows the user to visually compare and confirm the ra-
tios of soda-to-syrup and water-to-syrup. A refractometer (Not available
from Wunder-Bar) is a hand-held optical device used to measure the
amount of sugar in solution in beverages containing sugar.
In order for accurate Brix measurements or readings to be made, it will be
necessary to "ice down" the cold plate, by covering the cold plate located in
the bottom of the ice bin with a minimum of 4” to 6” of ice. If a mechanically
refrigerated beverage chilling system is to be used, instead of a cold plate,
turn ON the refrigerated, re-circulating beverage unit and allow it to “chill
down” to normal operating temperature before attempting to take Brix read-
ings or measurements. Once the cold plate or refrigerated unit have
reached temperature, dispense approximately 10 to 12 ounces of each bev-
erage just before attempting to “read” each products’ brix.
SETTING THE SODA AND WATER FLOW RATES
Set the flow rate to your specifications or to the nominal flow rate of 5 oz of
soda in 3 seconds. Dispense soda, through nozzle, into the large chamber
of the Brix Cup or a measuring cup. Squeeze the two tabs together and re-
move the manifold cover. Adjust the brix screw at the "S" position on the
product manifold by turning the screw
counter-clockwise or “out” to in-
crease flow rates and clockwise or “in” to decrease flow rates ( Fig.6 ).
The brix screws are the exposed screws on the product manifold. Do not
turn the “Shut-Offs” to adjust the brix ratio. The shut-offs are closest to the
input fitting side of the manifold and are open when the Shut-Off tabs or
screw slots are in line with the flow of product through the manifold (
see
Fig.7 ). Repeat the adjustment process to set the water flow rate
to 5 oz. of water in 3 seconds.
ADJUSTING THE BRIX RATIOS
Now that the soda and water flow rates are set, product brixing
may begin. The "L" button corresponds to the "L" position on the product
label at the manifold. The "C" button corresponds with the "C" position on
the manifold, "T" for "T", etc. The syrup brix screws are adjusted in the
same manner as Soda and Water Brix Screws;
counter-clockwise or "out"
increases flow rates, clockwise or "in" decreases flow rates. The most
common ratio for Post-mix beverages is 5:1 (5 parts soda or water to 1 part
syrup). However, some specialty beverages have 5.5:1 or higher ratios.
Some juices and mixers have ratios as low as 1:1 to 2:1. Always read the
BIB (Bag-In-Box) syrup container label for ratio specifications before start-
ing. The small chamber (syrup side) of brix cup should fill to 1 oz. in the
same amount of time it takes to fill the large chamber 5 oz. of soda or wa-
ter—confirming a 5:1 brix ratio (
Fig.5 ). If the product was 4:1 ratio, the small
chamber would fill to the same 1 oz. mark, but the soda or water would fill to
4 oz. Repeat until all products are properly brix ratio’d.
SECONDARY WATER BRIX SCREW (Fig.8)
All Wunder-Bar® Post-Mix and Juice dispensers have a “Secondary Water
Adjustment Screw” to enable juices and beverages with 2:1 and 1:1 ratios to be dispensed through buttons
located under the lower right Butterfly Plate. The Secondary Water Brix Screw is factory set to the “open”
position. Use a small bladed screwdriver to turn the screw Clockwise or “in” to decrease water flow to
achieve 2.1 to 1:1 ratios for products like tomato juice and Bloody Mary Mix.
