Dairy-Grade Fluid Equipment Daily Maintenance Guide
Maintenance Pain Points: Poorly Maintained Dairy Equipment Equals Production Hazards
- Food Safety Risk: Dairy-grade equipment has long-term contact with high-protein dairy products. Residue can easily breed bacteria, and inadequate cleaning affects product safety.
- Equipment Damage: In humid climates, metal parts of equipment are prone to rust, shortening service life.
- Operational Losses: Improper maintenance leads to frequent equipment failures, delaying 24-hour continuous production and causing significant losses.
3 Key Practical Maintenance Points for Dairy-Grade Fluid Equipment
1. Daily Cleaning: Dairy-Grade Standards to Eliminate Residue
- Post-Production Cleaning: After each production run, pipelines and tanks must be flushed with hot water above 85 deg C plus food-grade cleaning agent. Focus on cleaning areas prone to residue such as valves and seals (complying with GB 12693 hygiene requirements).
- Weekly CIP Check: Conduct a self-inspection of the CIP (Clean-in-Place) system once a week to ensure cleaning pressure is at least 0.3MPa and temperature meets standards to avoid cleaning dead spots.
- Post-Cleaning Drying: After cleaning, wipe the equipment surface dry. In humid weather, ensure proper ventilation to prevent oxidation and rust on stainless steel parts.
2. Material Care: Targeted Response to Local Climate
- 304/316L Stainless Steel Parts: Wipe with a food-grade rust inhibitor once a month, especially at equipment joints and welds.
- Seals (Food-grade Silicone Rubber): Inspect every 6 months. If aging or deformation is found, replace promptly to avoid production delays.
- Motors, Pipelines, and Key Components: Avoid direct contact with moisture. Workshop can be equipped with dehumidification equipment to reduce humidity impact on electrical systems.
3. Regular Maintenance: Plan Based on Capacity Adaptation
- Small and Medium-sized Dairy Enterprises (5-30t/day): Conduct a comprehensive inspection once per quarter, focusing on sealing and operational stability of pumps and valves.
- Large Processing Plants (30-100t/day): Conduct spot checks of key components once per month, and invite the manufacturer for in-depth maintenance every six months.
- Record Keeping: During inspections, focus on recording equipment operating parameters to facilitate subsequent targeted adjustments.
Maintenance Summary
The maintenance of dairy-grade fluid equipment is not about repairing when broken but about daily upkeep. Stable equipment operation is directly related to order delivery and product safety. The core principle is Hygiene + Anti-corrosion + Stability.
