Food industry
The Process Control team has bee applying predictive control for more than 30 years to a wide range of processes in food industry.
The methodology based on models and the Sherpa’s experience are assets for the success of an optimization of the dynamic process handling.

Typical example : Evaporator
The evaporator runs continuously in a batch environment : the feed tank and concentrated tanks are respectively fed and emptied independently from each other at non predictable moments.In spite of the rather small structure, optimization appeared to be a fast solution for satisfying roughly three objectives simultaneously (level of each tank and outlet product concentration).
In case of conflict, the operator may decide to give advantage to one of the tanks.
The control improvement concerns the concentration control but also and mainly, the optimization guaranties a more stable behaviour of the whole system, avoids the inconvenient related to levels out of range (high or low).
Added to that, the model running inside the predictive controller is used for warning the operator about a possible drift of the concentration sensor.
