Step 7
Pour the product from the syrup sampling valve into
a cup. Close the syrup sampling valve by turning the
handle to the center position.

Step 8
Stir the finished product. Pour a small amount of
product over the refractometer. The br ix reading
should register 13 to 14. A reading higher than this
would cause a darker, richer product. The
refrigeration system would have to run longer to
freeze this excess syrup. A reading lower than this
could cause a freeze-up in the freezing cylinder
because of the excess water.

Step 9
To adjust the brix, turn the adjustment sc rew located
behind the drip tray shelf. Clockwise adjustments
increase the amount of syrup to water, and
counterclockwise adjustments decrease the amount
of syrup to water. Adjust the screw in small
increments and check the brix again.
Figure 33
Repeat this step until a correct brix reading is
registered.
Step 10
Once the proper brix has been achieved, turn the
handle “up” to allow product to flow to the mix tank.
Figure 34
Note: The position of the handle on the syrup
sampling valve determines the direction of product
flow. The down position opens the syrup sampling
valve for collecting brix samples. The center posit ion
shuts off the product flow. The up position direc ts
the flow of product to the freezing cylinder.
