The Challenge: Mineral Scale in Food Production
In the food confectionery industry, water quality directly impacts product consistency and equipment longevity. Salles Frères encountered several issues related to hard water:
- Rapid limescale buildup in pipes feeding washing and rinsing tanks for olives and vegetables.
- Frequent clogging of nozzles in spray systems used for brining and marinating.
- Reduced heat exchange efficiency in hot water boilers used for pasteurization processes.
- Increased downtime for manual descaling of mixing vessels used for tapenades and spreads.
