The challenge
The OEM was tasked with engineering a state-of-the-art powder handling line for infant formula. In this sector, microscopic product buildup (bridging) is a major risk, leading to cross-contamination and bacterial growth. Traditional surface treatments, like glass bead blasting, leave microscopic crevices that trap fine powders. This meant the end-customer would face unacceptably long and frequent cleaning cycles between product changeovers.
Why ViwateQ?
The engineering team needed a surface topography that actively prevented product adhesion while strictly adhering to EHEDG guidelines. Chemical pickling was rejected due to its environmental impact and its inability to physically round off the surface profile. ViwateQ was selected because its patented wet polishing process perfectly smooths out microscopic peaks, creating an ultra-hygienic, low-friction surface without utilizing any toxic chemicals.
Results & business impact
- Eliminated powder bridging: Complete prevention of product sticking in hoppers, chutes, and transport tubes.
- Immediate compliance: The superior Ra-value and topography ensured immediate EHEDG certification for the entire line.
- Faster delivery: By integrating a ViwateQ license in-house, the OEM eliminated external transport times, cutting total production lead time by two weeks.
“
In infant nutrition applications, hygiene is simply non-negotiable. The ViwateQ technology gives our powder lines an unmatched cleanability. The powder simply slides off the surface, allowing our end-customer to significantly increase their daily output by cutting down on cleaning time.
