Keep Your DEGONG Bottling Line Running at Peak Performance

Maintaining your beer filling machine is one of the most effective ways to ensure consistent product quality, reduce equipment downtime, and extend the lifespan of your bottling line. Proper maintenance keeps your brewery operating efficiently and helps prevent unnecessary production interruptions. This maintenance guide by DEGONG Brewery Equipment walks you through the essential steps to keep your bottling system clean, accurate, and reliable.

1. Why Regular Maintenance Is Essential

A beer filling machine operates in a demanding environment that requires precision, sanitation, and stability. Without regular maintenance, you may face oxidation issues, inconsistent filling volumes, increased beer loss, or mechanical failures.

Key benefits of proper maintenance:

• Improved beer quality: Clean contact surfaces reduce oxygen pickup and protect flavor stability.

• Longer equipment lifespan: Preventing wear and corrosion reduces the need for costly repairs.

• Lower operating costs: Replacing small components early prevents major failures later.

• Higher production efficiency: Fewer stoppages mean more reliable output.

2. Understanding How a Beer Filling Machine Works

A modern bottling or canning line normally includes:

• Conveyor system to move containers

• Rinsing unit to sanitize bottles or cans

• Isobaric filling heads to reduce foaming

• Capping or sealing system

• Pneumatic and electrical control system

• Cleaning-in-place (CIP) system for automated sanitation

By understanding how these components work together, operators can maintain the machine more effectively and recognize early signs of malfunction.

3. Daily Maintenance Checklist

To keep your DEGONG beer filling machine in optimal condition, the following tasks should be performed every day:

• Rinse and sanitize all beer-contact parts

• Inspect filling valves for leakage

• Check for abnormal sounds or vibrations

• Verify CO₂ pre-purge and pressure settings

• Clean conveyors and work surfaces

Daily cleaning prevents the buildup of yeast, sugar, or protein residue that can contaminate beer and damage equipment.

4. Scheduled Weekly, Monthly, and Annual Maintenance

A structured maintenance plan ensures long-term reliability.

Weekly Tasks

• Lubricate chains, gears, and moving parts

• Inspect pneumatic actuators and hoses

• Check sensor alignment and accuracy

Monthly Tasks

• Replace worn seals or O-rings

• Calibrate filling heads for accurate dosing

• Clean or adjust conveyor belts and guides

Annual Tasks

• Perform a full equipment inspection

• Replace aging valves, gaskets, and bearings

• Evaluate machine performance and upgrade when needed

DEGONG recommends maintaining a detailed maintenance log to track each task and identify patterns that may indicate deeper issues.

5. Cleaning and Sanitization Procedures

Sanitation is the foundation of beer filling quality. Most DEGONG systems support CIP cleaning, enabling operators to automate the cleaning cycle.

Typical CIP Sequence:

• Pre-rinse with warm water

• Circulate alkaline detergent

• Acid rinse to remove mineral deposits

• Final rinse or sanitizing solution

For machines without fully automated CIP, removable parts such as filling heads or valves must be manually cleaned and disinfected.

6. Key Components to Inspect Regularly

Some parts experience higher wear due to repetitive movement or beer contact. These include:

• Filling valves

• Sealing rings and O-rings

• Conveying belts

• Bearings and bushings

• Foam eliminators and CO₂ purge systems

Replacing worn components promptly prevents downtime and ensures accurate filling performance.

7. Lubrication Guidelines

Use food-grade lubricants on:

• Conveyor chains

• Gearboxes

• Cam followers

• Slide rails

Avoid over-lubrication to prevent contamination. All lubrication points should be documented in the maintenance manual provided by DEGONG.

8. Troubleshooting Common Problems

Excessive Foaming

• CO₂ pressure imbalance

• Warm beer or bottles

• Incorrect fill height

Inconsistent Filling Volume

• Dirty or partially blocked filling valves

• Incorrect calibration

• Worn seals

High Oxygen Pickup

• Insufficient CO₂ purging

• Delayed sealing

• Leaking valve components

Addressing these issues early reduces beer loss and improves shelf stability.

9. Tips to Improve Long-Term Performance

• Maintain a preventive maintenance schedule instead of waiting for failures

• Train operators regularly to prevent misuse or accidental damage

• Use high-quality replacement parts from DEGONG

• Record every maintenance action to track wear trends

A well-maintained filling machine delivers smoother operation, higher quality beer, and lower running costs.

Conclusion

A DEGONG beer filling machine is engineered for durability, precision, and hygiene. By following a structured maintenance plan—including daily cleaning, scheduled lubrication, and regular inspections—you can significantly extend the life of your filling line and ensure exceptional performance.
