Control System
AssemblyA PLC holds the vacuum and steam pressure and adjusts feed and product flow to hit a target concentration, usually inferred from a density or refractometer reading. It coordinates the steam, vacuum, and pump loops and runs the CIP sequence. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
