Equipment Maintenance and Reliability

Maintenance preserves more than availability. Mechanical condition affects particle size, temperature, dose, seal integrity, drainage, foreign-material risk and the validity of process records.

Tasks should be based on manufacturer guidance, operating hours, risk, history and inspection findings. A calendar alone is weak when load and wear vary substantially.

Knives, plates, bearings, belts, pumps and seals need defined acceptance criteria. Dull, loose or misaligned components can heat, smear, shed fragments or create inaccessible gaps.

Lubricants, sealants, cleaners, welding materials and replacement parts must be suitable for their location and intended use. Food-grade status does not permit uncontrolled product contact.

Maintenance work requires isolation, tool and part accountability, cleaning and documented release. Temporary repairs should be time-limited and assessed for hygiene and physical hazards.

Downtime, repeated faults, alarm history and rejected product should feed the maintenance plan. Recurring repair of the same symptom without root-cause action is not effective control.
