In every brewery, fermentation tanks play a central role — transforming wort into beer through precise temperature and yeast control. However, these tanks operate under pressure, variable temperatures, and continuous exposure to CO₂, acids, and cleaning chemicals. Without proper care, their lifespan and performance can deteriorate rapidly.
At DEGONG, we manufacture and engineer high-grade stainless steel fermentation tanks built for durability, hygiene, and long-term stability. Based on over 15 years of brewery equipment experience, our engineering team shares key strategies to extend the service life of your fermentation tanks — ensuring maximum efficiency, lower maintenance costs, and consistent beer quality.
The foundation of a long-lasting fermentation tank starts with the material and fabrication quality.
Material: DEGONG uses 316L food-grade stainless steel, offering superior resistance to acids, alkalis, and high CO₂ environments.
Surface Finish: Internal surfaces are polished to Ra ≤ 0.4 µm, minimizing microbial buildup and simplifying cleaning.
Welding: Full TIG welding with 100% argon protection eliminates weak points and ensures seamless hygiene.
Insulation: Dual-layer construction with polyurethane foam maintains stable temperatures and reduces thermal stress.
Choosing high-quality stainless steel and precision welding technology is the first and most critical step toward extending tank service life.
Temperature, humidity, and pressure fluctuations can stress your tank over time. Maintaining stable conditions not only protects the equipment but also ensures better fermentation performance.
Keep ambient humidity below 70% to prevent condensation and external corrosion.
Avoid rapid heating and cooling cycles — thermal expansion can cause weld fatigue.
Operate within the rated pressure range (0–3 bar); never exceed design specifications.
Ensure proper ventilation around the tank to avoid CO₂ accumulation.
Consistent environmental control reduces metal fatigue and prolongs both tank and component lifespan.
Cleaning and sanitation (CIP) are vital to beer quality, but if performed incorrectly, they can damage your tank’s surface or shorten gasket life.
Rinse with warm water (40–50 °C) to remove residual beer or yeast.
Circulate alkaline cleaner (NaOH 1–2%) for 20–30 minutes.
Rinse thoroughly until pH is neutral.
Use acid rinse (HNO₃ 0.5–1%) every 3–5 cycles to remove beer stone.
Final rinse with sterilized or deionized water.
Avoid using excessively strong acids or chlorinated cleaners, which can pit the stainless steel surface. DEGONG recommends periodic passivation every 6–12 months to restore corrosion resistance.
Advanced monitoring extends both efficiency and longevity. DEGONG fermentation tanks can be equipped with:
Temperature probes for accurate fermentation control
Pressure sensors with automatic vent valves
pH and CO₂ monitors for yeast management
PLC systems (Siemens / Omron) for automated control and data logging
Early detection of abnormal temperature or pressure prevents mechanical stress and helps avoid costly repairs.
Like any precision equipment, some components require regular inspection and replacement:
Seals and gaskets: Replace every 6–12 months or sooner if deformation occurs.
Safety valves and pressure gauges: Test every quarter.
Piping and clamps: Inspect for leaks and wear after each CIP cycle.
Cooling jackets and glycol lines: Flush periodically to prevent scaling.
By replacing inexpensive parts on time, you can prevent large-scale failures and protect your equipment investment.
Avoid excessive vibration from nearby pumps or compressors.
Ensure all tanks are mounted on stable, level flooring.
Use food-grade lubricants on valves and mechanical seals.
Keep cleaning chemicals in correct concentration — over-dosage can corrode surfaces.
Rinse immediately after CIP if the tank will remain idle for long periods.
Each of these small practices contributes to longer equipment life and smoother operations.
When investing in new equipment, choose a design that reduces long-term stress and simplifies cleaning. DEGONG Fermentation Tank Design Highlights:
Conical bottom (60°) for efficient yeast collection
Dimple jacket with zone cooling for uniform temperature
CIP ball positioned for 360° internal coverage
Sampling port and pressure-rated manway
Insulated sidewalls and top dome for temperature stability
Our tanks are engineered not only for durability but also for operational convenience, helping brewers maintain consistent performance for years.
Preventive maintenance ensures small issues don’t escalate into costly downtime.
A recommended schedule includes:
Daily: Visual inspection and quick rinse
Weekly: CIP and pressure test
Monthly: Valve and gasket check
Quarterly: Full mechanical inspection and data calibration
Annually: Re-passivation and performance audit
DEGONG provides detailed maintenance manuals and remote support to guide brewery owners in establishing efficient maintenance cycles.
