Open the sample valve. Adjust the water flow rate to 1.5 oz/sec (44.4 ml/sec) by dispensing water
from the solution module through the sample port for 10 seconds into a measuring cup. The
amount measured should be 15 oz (444 ml). Turn the flow control clockwise to increase the flow
and counterclockwise to reduce the flow.
10.
Open the syrup supply valve and check syrup line connections for leaks. Preset syrup flow by
turning flow controls two and one fourth (2 1/4) turns clockwise on solution module.
11.
Place a container under the sample port (see
Figure 6.2
) and open the sample valve until a good
water and syrup mixture is obtained. This sample should be discarded.
12.
Dispense a 9-12 oz sample and measure the brix with a refractometer. Be sure to thoroughly mix
the sample first by pouring back and fourth in two cups.
13.
Turn the syrup flow control counterclockwise to decrease the brix. Turn the syrup flow control
clockwise to increase the brix.
14.
Dispense and discard several samples after adjusting the brix.
Note:
Do not adjust the brix with the water flow control setting unless you are unable to obtain the
desired brix with adjustments to the syrup flow control. The brix reading is affected by temperature;
samples taken from the barrel should be at the same temperature as from the sample valve.
15.
Repeat steps 8 through 14 for other barrel.
The target brix for most sugar flavors is between 13.5 and 15. The target brix for most "light" flavors will be
lower, usually between 9 and 10. Check the specifications for the flavors if unsure of the target brix.
Note:
Light or diet products have a low brix and can cause problems with the dispenser if not properly set up.
Although these products have ingredients to replace the antifreezing properties of sugar, they can still create
excessive ice if not carefully brixed according to their specifications. Low brix issues will be associated with
events such as audible ice scraping during freeze and low beater problems.
