Arla Foods Holstebro annually produces 58,000 tons of cream cheese in various flavours. Approximately 3,500 plant components are connected to the control system. Success criteria for the technical solution were to achieve an open system that Holstebro itself could maintain/enlarge, a future-proof investment, plus encapsulating the knowledge and experience in the dairy. Furthermore, it was constructed in accordance with Arla Foods’ Standards ISA S88/ISA S95, and built for data collection and traceability through integration to the Arla Foods IT reporting system and SAP.

Scope of Supply

• 8 Siemens S7-414 PLC’s;
• 1 Wonderware Intouch station with big screen in the control room;
• 14 Wonderware Intouch stations distributed in the respective control rooms and process area;
• 3 redundant Wonderware IAS servers;
• 1 Siemens programming station;
• ISA S88 structured Siemens software application;
• Wonderware Intouch SCADA application;
• Data collection for the ISA S95 structured database.

Project Process

The project was initiated in early 2009 and extended over three years. It was carried out as a step by step upgrade/development, in order that the commissioning was implemented with minimum interruptions. The project was implemented in close co-operation with Holstebro’s technical personnel and operators.

Benefits For Arla Foods

As result of the upgrade Holstebro has since 2008 reduced its costs for electricity, steam and ice water by over 20%, and for water and chemicals by over 30%. Additionally, the maintenance costs for the control system have been reduced and its flexibility and integration possibilities have increased. As a natural part of the upgrade Holstebro has implemented a good deal of optimization and expansions of the process plant. Today there is better traceability and far better reporting capabilities than before.
