For the past 18 months, we have used a new, highly efficient membrane technology for beverage carbonation.
Coupled with mass flow measurement and PLC control, we achieve straightline carbonation performance under typical filler start-stop conditions. (slide#1) Accuracy is typically 0.25% of CO2 setpoint as measured at the outlet of the system. The is equivalent to +/- .01 CO2 volumes for a 4.0 volume beverage.
This performance level is a significant improvement over other carbonation technologies which report accuracies ranging from 1.0% to 2.5% of CO2 setpoint.
To fully describe this developemnt (slide #2), I will briefly summarize our background requirements, discuss processing system design, expalin the new membrane technology, and conclude with performance data.
