PLC/SCADA/IoT Systems Already Automating Core Monitoring Tasks
#1PLC/SCADA automation of food processing and cooking operations is not an emerging trend — it is an operational reality that has been deployed at scale in large food manufacturers for over a decade and is now actively diffusing to mid-size facilities through falling hardware costs and SaaS-model MES platforms. Automated retort systems from JBT Corporation and Stock America are documented to operate entire sterilization rooms with 80–85% headcount reductions relative to manual operation; a single SCADA operator supervises 4–6 fully automated retort vessels. IIoT platforms from Rockwell Automation, Siemens, and Honeywell are actively marketed to mid-tier food processors with ROI claims based explicitly on labor cost elimination. The barrier to adoption at smaller facilities is falling as cloud-based SCADA (IgnitionCloud, Aveva Connect) eliminates the capital cost of on-premise infrastructure.
