Clean-in-place is only as reliable as the instruments that govern it. In a food and beverage plant, a CIP circuit has to prove that the right solution reached the right line, at the right strength and the right temperature, for the right duration — and that used solution never found its way back into the fresh supply. That proof comes from the instrumentation and control layer, not from the pipework.
Valve operation is handled by air-operated, solenoid-controlled valves with positive feedback, so the control system knows the actual valve position rather than assuming it. Timed sequences route the rinse water, alkali and acid stages in turn, and fail-safe mechanisms prevent pump dry running. Temperature is held by steam heat exchangers under PID control, regulating cleaning solutions to specific ranges such as 60°C–85°C, with steam thermostats maintaining consistency — hot enough to break down residue, but controlled to avoid thermal degradation of the cleaning agents themselves.
Hygienic integrity is protected by air gaps in the return flow circuits, which prevent backflow contamination and ensure used cleaning solutions cannot re-enter the fresh supply across the plant. Advanced CIP systems add pH and conductivity sensors directly into the cleaning lines to continuously analyse and maintain chemical concentration, ensure precise chemical action, and reduce overuse of cleaning agents by up to 20%.
PMG Engineering's CIP design work targets maximum efficiency, compliance with hygiene standards and operational cost savings. We specialise in design, instrumentation and automation design and architecture, preparation of BOQ and tender documents, layouts and elevation, through to release of GFC drawings.
