Regular maintenance is the foundation of a stable, efficient, and high-quality brewing operation.
Proactive maintenance ensures consistent product quality, minimizes downtime, and extends the life of all brewery systems.
Key benefits:
Maintain consistent beer quality and flavor
Prevent unexpected breakdowns and production interruptions
Reduce long-term maintenance costs
Improve operational safety and compliance
| Issue | Typical Symptoms | Impact |
|---|---|---|
| Equipment Aging or Failure | Pumps, heat exchangers, fermenters, and filters wear out or leak | Production stops, inconsistent quality |
| Contamination or Odor | Microbial growth, residues, or scaling in tanks and pipelines | Off-flavors, beer spoilage |
| Temperature Control Problems | Faulty sensors or unstable glycol system | Fermentation deviation, alcohol inconsistency |
| Automation Malfunctions | PLC, sensors, or actuators fail | Disrupted process flow, inaccurate dosing |
| Accessory Wear | Seals, gaskets, and valves deteriorate | Leakage and energy loss |
| Poor Facility Conditions | Inadequate ventilation, lighting, or safety measures | Increased safety risk and poor hygiene |
Develop a routine inspection plan for key systems such as fermenters, cooling units, heat exchangers, pumps, and pipelines.
Lubricate, tighten, and clean components regularly.
Replace worn seals, gaskets, and valves before failure occurs.
Perform CIP (Cleaning-in-Place) or manual cleaning for all parts that contact wort, beer, or yeast.
Use food-grade cleaning and sanitizing agents; avoid chemical residues that affect taste or safety.
Calibrate temperature sensors and controllers regularly.
Check glycol chillers, heat exchangers, and steam systems for leaks or scaling.
Conduct chemical descaling or back-flushing of the heat exchanger as required.
Test PLCs, sensors, transmitters, and actuators periodically.
Back up control programs and process data.
Clean electrical cabinets, ensure proper cooling and insulation of components.
Keep inventory of key spare parts such as gaskets, valves, and pump seals.
Replace any corroded or worn components promptly to avoid downtime.
Maintain good ventilation, lighting, and cleanliness across all production areas.
Inspect fire protection, electrical safety, and chemical storage regularly.
Manage cleaning chemicals properly to prevent safety risks.
Train operators and maintenance personnel on routine checks and troubleshooting.
Maintain detailed equipment logs, including maintenance dates, repair history, and replacement records.
Assign dedicated maintenance engineers to oversee preventive programs.
Use process data to optimize fermentation, cooling, and CIP cycles.
Adopt smart sensors and IoT monitoring for temperature, pressure, vibration, and energy consumption.
Implement a CMMS (Computerized Maintenance Management System) to manage schedules, spare parts, and alarms efficiently.
| Frequency | Key Tasks |
|---|---|
| Daily | Check temperature and pressure; perform quick cleaning after production. |
| Weekly | Clean heat exchangers; lubricate pumps and motors; inspect for leaks. |
| Monthly | Calibrate sensors; verify automation and control system stability. |
| Quarterly | Deep-clean fermenters; inspect heat exchangers and electrical systems. |
| Annually | Full system shutdown inspection; replace all seals and gaskets; evaluate upgrades. |
Minimize unexpected downtime and costly repairs
Ensure consistent beer quality and process reliability
Extend equipment service life
Enhance safety and regulatory compliance
Support digital transformation and intelligent maintenance management
Proactive maintenance is not just a task — it’s a mindset that defines a professional brewery.
At DEGONG, we encourage every brewer to integrate preventive maintenance into daily operations.
A well-maintained brewery is safer, more efficient, and produces better beer — every single batch.
