The current design of the machine presents efficiency and performance problems,mainly due to over-foaming and lack of accurate fill level controls. A flowdynamics analysis was done with the intention of understanding the factorscontrolling the foam formation and propose improvements that will directly impactthe machine´s KPI´s.

As result of the analysis the change from counter pressure to atmospheric filling isproposed as well as the re-programing of its PLC together with physical changes tothe flow path, and the use of a better suited speed controlling device.

The proposed fill speed controlling device was analyzed with the aid ofcomputational fluid dynamics software and then quantitatively characterized. Allthe proposed changes suggest a possible change in speed from 3 bottles per minuteto above 8.5 bottles per minute with minimum intervention to the machine.
