Visualization and control of the processes of cooling and freezing at the Dutch company Zandbergen World's Finest Meat

Headquartered in the Dutch municipality of Zoeterwoude, Zandbergen World's Finest Meat is a leading company in the international protein supply chain.

They import chilled and frozen meat (beef, lamb, pork, poultry) from the USA, Argentina, Brazil, Uruguay, Paraguay, Chile, Thailand, Australia, and New Zealand.

The meat is prepared in various ways (portioned steaks, hamburgers, sliced and cubed products) to meet the needs of a wide variety of customers. It is then supplied to all EU countries, Switzerland, Norway, and the United Arab Emirates. Since 2018, the company has also been offering alternative protein solutions.

In March 2020, the Dutch company Chiron-tec B.V. implemented a system for the control and monitoring of the processes of cooling and freezing at Zandbergen's production facility.

Control system

The system consists of a Siemens SIMATIC S7-1500 PLC (with 1,100 IO signals) and the Reliance SCADA/HMI system.

It is used for the control and monitoring of the production facility's:

• Engine room
• Industrial heat pump
• Cooling and freezing rooms
• Air handling units

Among other things, the control system is also used for:

• Displaying and printing trends
• Floor plan monitoring
• Email notification in case of an alarm

For the purposes of efficiency calculations and research, a pressure-enthalpy diagram is made dynamically to see what the design values are compared to the actual values when the heat pump is running.

To replay the history in the diagram, Reliance's Postmort function is used.
