HMI Architecture in Dairy & Chemical CIP Washdown: Die-Cast Aluminum vs. SUS304 Stainless Steel
Automated clean-in-place (CIP) and clean-out-of-place (COP) sanitation routines in dairy bottling, milk pasteurization, and chemical mixing facilities represent some of the most aggressive physical environments for industrial automation electronics. Lines undergo multi-stage washdowns involving 1.5% to 2.0% hot sodium hydroxide (caustic soda, pH ≥ 12) at 75°C, followed by intermediate nitric or phosphoric acid rinses
