Swiss technology group Bühler is taking the long-lasting and fruitful relationship with Kägi Söhne AG, the Swiss chocolate wafer producer, to the next level. Bühler is supporting Kägi in building its smart factory. One of the first actions of the team was to connect most of Kägi’s production to the Insights platform, Bühler’s digital tool that connects devices, operational metrics, and analytics. With that, the level of transparency on process and machine data has increased significantly.

From raw materials, to baking and filling of wafer sheets, and to chocolate coating, data can now be recorded, analysed, and interpreted at any time. In addition, all process-relevant data and KPIs for each production step are visualized via dashboards. All this results in higher performance and optimization of processes. By linking and visualizing the data in Bühler Insights, Kägi expects to see an Overall Equipment Effectiveness (OEE) increase of 5 to 8 %.
