Dissolved Oxygen
Dissolved oxygen (dO2) must be tested before, during, and after every run. It is highly recommended to first check the
brite tank dO2 level, and then to check seamed cans during and after the packaging session for dissolved oxygen. This
must be done on ever canning run to ensure proper operation and good manufacturing practices. It is not uncommon
for an ABE canning line to produce seamed products under 100ppb or 50ppb while adding 10-15 ppb of oxygen above
what level is provided to the line from the brite tank. Therefore, it is also important the brite tank oxygen level be as low
as possible. Acceptable craft beer dO2 levels are attainable with proper maintenance to the ABE machine, proper
brewing practices, and tight connections from the brite tank and throughout the canning line.
Higher than preferred dissolved oxygen levels are typically attributed to a loose fitting which has beer passing through it.
If a fitting is not tight, oxygen may enter the system and higher than preferred dissolved oxygen levels may result.
Furthermore, there cannot be oxygen in the headspace of the can. The headspace must be filled with CO2. The
headspace should not be filled with product as this overfills the can.
Consult your specific dissolved oxygen meter for specific uses. Always check the brite tank first and then the can's total
dissolved oxygen level.
Troubleshooting
a.
Ensure brite tank dO2 level is acceptably low before checking the canning line dO2 levels.
b.
Check all connections (tri-clamps, push to connect fittings, etc.) are properly tightened between the
brite tank and fill nozzles.
c.
Is one specific nozzle producing a higher dO2 level than another?
a.
If so, check for loose fittings
d.
Is there sufficient foam atop the product so no area for air is able to be trapped?
a.
See section Filling for foam troublehshooting.
e.
Is the undergassing co2 turned on at the lid chute and in the lid-chute tunnel?
Consult ABE if your levels are higher than acceptable.
