Defoaming Technology

Beer Bottling & Canning Lines

The beer foam control system is not designed to eliminate foam in the brewery packaging lines but to compress the foam down in the can or bottle into a denser foam with smaller bubble characteristics. This enables the foam control system to deliver significant productivity gains, filling line efficiency gains, reduced beer waste, reduced contamination, energy & water saving and quality improvements whilst still keeping the TPO/oxygen levels in good specification range

Key Benefits

  1. Increased filling line speed (10-50%): enhanced productivity gains or reduced operational days per week (savings on labour, energy, water, cleaning cycle/chemicals, waste treatment)

  2. Reduced beer extract losses by an average 1ml to 5ml per can or bottle: due to the foam compression effect, beer losses are reduced and more beer is kept in the bottle or can. Adjustment of the fill settings (volumetric filler) or tube length on filler valves (mechanical filler) allows for the beer loss saving to be realized.

  3. Reduced beer waste (waste treatment cost): reduced waste treatment costs (beer/water/chemicals)

  4. Reduced bottle & can rejects due to underfill: reduced beer losses, packaging material and reduction in waste treatment costs

  5. Reduced CO2 consumption on bubble breakers or in most cases elimination of CO2 bubble breakers whilst still keeping TPO/Oxygen the same and in good specification range

  6. TPO/Oxygen levels in the head space of the capped bottles/cans remain the same or in certain situations lower than the standard process

  7. Enhanced hygiene, reduced contamination on package and filler: due to the foam control effect, beer stays in the bottle or can instead of contaminating the bottle and can filling line zone resulting in a cleaner line and potentially reduced cleaning cycles/CIP (energy, water, chemical saving, reduced down time on filler)

  8. Filling temperature increase: For lines where beer is flash pasteurized before the filler, potential to increase filling temperature to ambient fill (energy cost saving, eliminate condensation issues on bottle or can impacting down-stream processes in the plant (labeller, packing logistics)
