Keeping an industrial food process on target through automatic, usually computerized, regulation. Networks of sensors feed measurements of temperature, pressure, flow, pH, and moisture to controllers that adjust valves, heaters, and pumps in real time, holding every variable inside validated limits. Good control smooths out raw-material variation, cuts energy and waste, protects safety margins in thermal processes, and delivers the batch-to-batch consistency modern brands require. Engineers tune the control loops during commissioning and revalidate them whenever recipes or equipment change.
