According to Andrew Sprigg, control systems engineer at Metromotion Controls, “Rockwell Automation is the automation vendor of choice for Chobani so by having one brand for standardisation; maintenance, service and support is streamlined for the plant.”
“The cooperation between Rockwell Automation, NHP, Metromotion and Chobani has worked really well and this good working relationship has helped everything to flow smoothly,” he said.
Driving Production Efficiencies
The yogurt production process is fully automated using the latest control and automation technologies from Rockwell Automation. Ethernet/IP™ is used as the communications protocol with all devices connected via the one network.
The architecture at the plant has been designed so that five independent ControlLogix® controllers are used for a specific process role such as raw milk processing, pasteurising, cleaning in place (CIP), fermentation and filling.
Each part of the process is further broken down into modular skids. A control panel with FLEX™ I/O communicates the process information back to the ControlLogix controller over Ethernet. This provides the capability for remote access diagnostics of equipment easily over the Ethernet network.
The motor control utilises PowerFlex® drives from Rockwell Automation that are located in a centralised motor control centre and communicate over the Ethernet network.
