Small stones. Big operational impact.
Small stones can create major disruption in potato chips processing.
Even after washing, sorting and inspection, embedded stones may still reach the cutting stage. Once inside the cutting head, they can strike several blades in succession, causing repeated blade damage, unplanned stops and less predictable slicing performance.
That is why FAM STUMABO developed StoneExtractor.
Its redesigned segment geometry improves stone evacuation inside the cutting head, helping guide small stones out of the cutting zone immediately after impact. The goal: reduce cumulative damage and support more stable production, especially when raw material conditions become more challenging.
The solution has already been validated under real industrial conditions at Kelly Ges.m.b.H., Austria’s market leader in salty snacks, where it helped reduce blade wear and unplanned stops.
StoneExtractor: designed to keep stones moving out, not around.
