Syrup/Concentrate; Setting Ratios - Cornelius UF-1 Training Manual

UF-1 and UFB-1 Valves Training Manual

2. Syrup/Concentrate

Syrup should always be pre-cooled before setting the ratio. Syrup takes a path through the valve parallel to
the water path. It is introduced in the block, travels through a syrup flow control, banjo, valve head and out
the nozzle. Note, concentrate is not cooled.
High sugar syrups are more viscous (thicker) than diet syrups and consequently have more pressure drop
within a system. This pressure drop results in less flow at the valve and therefore a slower fill time. Increasing
the pump pressure will help overcome the pressure drop caused by high sugar syrups.

3. Setting Ratios

If the ratio varies and must be adjusted often, it is probably the result of a restricted syrup system. It is then
time to clean and sanitize the syrup tubing and cooling coils and check for other problems such as syrup
pumps, etc.
Note: Try raising the pressure on the pump before cleaning.
Set the water flow rate first, then adjust the syrup to the desired ratio. This gives the most accurate valve
flow setting possible. Measure the ratio and adjust the syrup flow, if necessary. This will result in uniform
flow, better carbonation retention, and improved drink quality.
When using a ratio cup always take these precautions to ensure accuracy:
• After installing the separator tube, open the valve to fill the syrup tube before starting the ratio test.
• Clean the cup thoroughly between tests so there is no carry–over from one test to the next.
• Fill the cup to approximately 3/4 full and use approximately the same quantity for each test to ensure
accurate settings.
• Take another sample to verify the settings.
