Beer Fermentation Tanks

Beer fermentation tanks are essential equipment for proper beer production. This guide provides a comprehensive overview of beer fermentation tank types, sizes, layouts, suppliers, prices, and technical considerations for installation, operation, and maintenance.

Overview of Beer Fermentation Equipment

Beer fermentation is a critical step in brewing where yeast converts sugars into alcohol and carbon dioxide. Proper temperature control, agitation, and yeast health optimization during fermentation ensures high quality, consistent beer output.

Special fermentation tanks are used to provide optimum conditions for yeast activity. Key equipment pieces include:

Fermentation Vessels – Cylindroconical stainless steel tanks that hold beer during the fermentation process. Available in different diameter to height ratios. Fitted with cooling jackets, agitators, yeast collection systems and CIP sprayballs.

Temperature Control Systems – Cooling jackets around tanks use glycol/ammonia/freon systems to maintain steady fermentation temperature profile.

Yeast Propagation Systems – Special mini fermenters to grow sufficient healthy yeast for pitching into main fermentation tanks.

Yeast Storage Tanks – After fermentation, yeast sediment is collected and stored for reuse.

Carbonation Systems – Equipment for controlled injection of CO2 post-fermentation prior to bright beer tank storage.

Monitoring & Automation – Sensors, transmitters, process controllers are used to track temperature, density, pH and automate tank processes.

Proper fermentation tank configuration is critical for efficient beer production, quality and yield.

Beer Fermentation Tank Types

Many fermenter tank designs exist for different batch sizes, beer types and workflow formats. Main equipment configurations include:

Tank Type	Description
Cylindroconical Tanks	Cone bottom tank with cylindrical upper section.  Most common design with efficient yeast separation.  Available from few BBLs to thousands of BBLs capacity.
Open Fermenters	Flat/sloped bottom, open top rectangular vessels.  Allow easy access for fruit/ingredient addition. Limited to certain ale beer styles suited to ambient exposure.
Closed Fermenters	Cylindrical tanks with dish/conical bottom and closed top.  Range from 5 to 30 BBLs. Used for ales and lagers.
Horizontal Fermenters	Cylindrical tanks placed in horizontal orientation.  Require less vertical headroom. Up to 800 bbls.
Mixed Fermentation	Combination of vessel types for primary and secondary fermentation steps.  Open tanks used for initial activity followed by closed tanks.

Beer Fermentation Tank Sizes

Beer fermentation tanks cover a wide range of sizes from a few barrels to massive volumes over 1000 barrels. Some typical fermenter capacities include:

• Pilot Systems: 1-3 BBL
• Microbreweries: 3-7 BBL, 7-30 BBL
• Pub Breweries: 15-30 BBL
• Production Breweries: 30-300 BBL, 600-800 BBL, 1000+ BBL

Larger tanks have advantages of higher volume and less cleaning/handling per barrel but need substantial space and capital investment. Smaller tanks provide flexibility for more beer varieties.

Typical fermentation tank size selection considers:

• Annual beer production targets
• Peak seasonal production capacity
• Floorspace and height constraints
• Budget

With multiple fermenters, it is also important to have the right tank mixing – small and large units that can handle both flagship brews and experimental pilot batches.

Beer Fermentation Tank Designs

Fermenter tanks have different designs and accessory fittings tailored to facility requirements:

Parameter	Options	Advantages	Limitations
Geometry	Cylindroconical <br> Horizontal Cylindrical <br> Open Top Rectangular	Efficient yeast settling <br> Height reduction <br> Accessibility	Tall height <br> Difficult CIP <br> Exposure risk
Construction	Stainless Steel <br> Aluminum <br> Plastic	Durable, impermeable <br> Cost-effective <br> Disposable	Cost <br> Reactive material <br> Single-use
Heating/Cooling	Cooling Jacket <br> Internal Cooling Coil <br> External Heating/Cooling	Uniform temperature <br> No contamination risk <br> Flexible applications	Complex install <br> Limited cooling <br> Hardware requirements
Agitation	Top-mounted mechanical <br> Side-mounted mechanical <br> Airlift pneumatic	Full mixing profile <br> Avoid top intrusions <br> No sealing requirements	Bearing maintenance <br> Shear effects <br> Weaker mixing
Yeast Handling	Conical bottom <br> External separator tank <br> Slope sheets	Compact design <br> Adjustable capacities <br> Easier cleaning	Height needs <br> Additional tank space <br> Leveling requirements

Planning Beer Fermentation Tank Layout

Fermentation room layout balances production workflow, equipment spacing, service access and expansion flexibility:

• Linear layout places tanks in a single row
• Cluster layout groups tanks together with open workflows
• Compact layout fits more tanks by minimizing aisle space
• Modular layout has moveable racks and standardized spacing
• Multi-level layout uses second level mezzanines for small FVs

20% extra area should be allocated for tank maintenance access and yeast propagation systems. FV orientation relative to other equipment in brewhouse impacts slurry transfers, cleaning, forklift logistics etc.

Customization Options for Beer Fermentation Tanks

In addition to standard tank accessories like cooling jackets, agitators, CIP components etc., customizations enable unique capabilities:

Automatic yeast pitching – Density sensors trigger pumps for pitching at the right fermentation phase

In-tank dry hopping – Special tank bottom section for dry hop addition without opening the tank

Advanced automation – Touchscreen controllers, remote monitoring and data analytics integration

Hybrid uni/multivessel – Single FV switches between unitary and multivessel modes

Pressure/vacuum rating – Withstand high CO2 volumes or vacuum conditions for specialty processes

Steam jackets – Live steam injection for temperature boost or hot water sanitization

** canker**- Internal or external tank cladding for insulation benefits

Such custom features help enhance efficiency, reduce labour and enable novel processing techniques but add cost and complexity. Brewers should assess value proposition for bespoke designs versus off-the-shelf standard tanks on a case-by-case basis.

Strict cleaning procedures between batches minimizes risk of contamination. Proactive inspections and preventative maintenance avoids unplanned downtime. Personnel must follow all standard safety protocols when working inside fermentation vessels.

Key Considerations for Selecting Beer Fermentation Tanks

Brewery Scale & Growth Plans

Match tank capacity and quantity to annual beer production targets. Factor in peak demand during seasonal spikes. Choose modular designs allowing incremental expansion without full system replacement.

Floor Plan Dimensions

Consider facility height, footprint and layout constraints. Measure doorway clearance, aisle width and overhead space to ensure tanks fit into building. Account for 20% extra space around tanks for operator movement and ancillary equipment.

Beer Variety Complexity

Simple lager portfolios need fewer larger fermenters while complex ales require more tanks with variable sizes for different recipes. Flexibility for short batch turnover around core brands allows innovation.

Budget Limitations

Weigh value of automation, exotic alloys and custom features versus basic functionality. Prioritize must-have accessories over nice-to-have upgrades given finite capex allocation.

In-House vs Turnkey Expertise

Evaluate ability to self-install tanks or outsource to specialists. Complex integrated systems with advanced automation may warrant vendor turnkey project. Simpler tanks can be DIY using modular designs and supplier support.

Future-Proofing Scope

Anticipate emerging beer trends, novel ingredients, and processing innovations that could require fermentation flexibility in 5-10 years. Choose designs accommodating projected needs via customization potential.

Regulatory Approvals

Get supplier support during certification process for welding standards, sanitary design, hazardous environment compliance etc. required by local food safety and alcohol bureaus.

Frequently Asked Questions (FAQ)

1) What working pressure should Beer Fermentation Tanks be rated for?

• For modern unitanks, target 1–2 bar (15–30 psi) MAWP with certified PRV/VacRV. This enables spunding, natural carbonation, and closed pressure transfers safely.

2) Jacketed vs. single‑wall: which is better for consistent fermentation?

• Jacketed stainless with glycol control and PID delivers tighter stability (±0.5–1.0 °F / ±0.3–0.6 °C) and faster crash cooling. Single‑wall tanks often require chambers or wraps and provide less precision.

3) How do I size glycol chilling for a cellar of Beer Fermentation Tanks?

• Plan ~1.5–2.0 refrigeration tons per actively fermenting 30 bbl FV during peak heat load; add 20–30% headroom and consider concurrency (e.g., simultaneous crashes). Consult OEM heat loss specs for your geometry and jacket area.

4) Which fittings/instrumentation add the most value on FVs?

• Tri‑clamp ports, sanitary sample valve, racking arm with position indicator, RTD in a thermowell, pressure transducer, carbonation stone with check valve, PRV/VacRV, and a CIP spray device sized to your pump.

5) How can I minimize oxygen pickup during dry hopping and transfers?

• Use purgeable hop‑dosers, CO2 purge tanks/hoses/BBTs, pressure‑transfer through purged lines, maintain gasket integrity and PRVs, and spot‑check DO at knockout and pre‑packaging where possible.

2025 Industry Trends for Beer Fermentation Tanks

• Oxygen‑aware cellars: closed dry‑hop dosing, pressure transfers, and inline/package DO checks are standardizing even in small breweries.
• Smarter telemetry: networked temp/pressure/SG sensors feed QC dashboards and traceability logs.
• Hygienic by design: shadowless manways, orbital welds, and validated spray coverage shorten CIP cycles and lower micro risk.
• Energy and water stewardship: better insulation, optimized jacket zoning, and CIP chemical optimization reduce utilities per hL.
• Modular scalability: retrofit kits for pressure capability, carb stones, level sensing, and jacket upgrades extend FV lifecycle.
