Predictive control of Hellmann's mayonnaise filling

Unilever reported 50% less overfill giveaway after introducing predictive filling control

WorkingCompany's own claim

Problem

The Hellmann's line at Pouso Alegre adjusted filling from downstream weight checks. Delayed feedback allowed excess mayonnaise into jars and increased material costs.

Approach

Unilever introduced Rockwell Automation's FactoryTalk LogixAI Perfect Fill. Its model used upstream process variables to predict fill quantities before filling and adjust equipment controls.

Results

50%reduction in finished-goods overfill giveaway on the Hellmann's line, reported by UnileverCompany's own claim[1]

Takeaway

The change brought process predictions into the filling controls before downstream weighing detected a deviation.
