Defoaming Technology

Dairy Industry Packaging Lines

Dairy Defoaming Equipment Delivering Production Efficiency and Productivity Gains

Key Benefits

  1. Ehanced hygiene, reduced contamination on package and filler: due to the foam control effect, dairy stays in the bottle, can or carton instead of contaminating the bottle and carton filling line zone resulting in a cleaner line and potentially reduced cleaning cycles/CIP (energy, water, chemical saving, reduced down time on filler). Eliminating contamination and risk for microbial growth on the caps, threads and seal of the package.

  2. Increased filling line speed (5-40%): enhanced productivity gains or reduced operational days per week (savings on labour, energy, water, cleaning cycle/chemicals, waste treatment)

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

  4. Reduced dairy waste (waste treatment cost): reduced waste treatment costs (dairy/water/chemicals)

  5. Reduced bottle & carton rejects due to underfill: reduced dairy losses, packaging material and reduction in waste treatment costs

  6. Enhanced efficiency of filling lines where nitrogen dosing is applied: due to the defoaming effect in the bottle or package prior to capping, increased nitrogen dosing efficiency and greater nitrogen content in the capped bottle or package.

  7. Applicable to skimmed milk, semi-skimmed milk, full fat milk, dairy mixers/smoothies (fruit flavours, chocolate, caramel, coffee), coffee milk drinks

Performance Guarantee
