Volume Considerations

The volume of a fermentation tank directly influences the capacity of the brewery and the efficiency of the fermentation process. Selecting the right tank volume involves balancing several factors:

Batch Size: The first step in determining the tank size is to consider the typical batch size the brewery plans to produce. The tank should be large enough to accommodate the entire batch with some headspace for foam and gas expansion during fermentation.
Headspace: It’s important to account for additional space at the top of the tank to manage krausen (foam created during fermentation) and to allow for gas exchange. Typically, this means sizing the tank to hold around 10-20% more than the actual batch volume.
Fermentation Time: The length of time that a batch will remain in the tank also impacts the required volume. Longer fermentation times may necessitate more tanks or larger tanks to maintain continuous production without bottlenecks.
Product Mix: Breweries producing a variety of beer styles may need tanks of different sizes to accommodate varying batch volumes and fermentation requirements. Smaller tanks might be used for specialty brews or seasonal products, while larger tanks handle the brewery’s core offerings.
Production Capacity: The overall production capacity of the brewery, including future goals, should be a guiding factor in determining tank volume. It’s essential to consider not just current needs but also potential increases in demand.

Scalability

Scalability is a vital aspect of tank design, particularly for growing breweries that anticipate an increase in production over time. The design and installation of fermentation tanks should allow for easy expansion without disrupting existing operations.

Modular Systems: One approach to scalability is using modular tank systems. These systems allow breweries to add more tanks as needed, increasing capacity in a controlled and manageable way. Modular designs also offer flexibility in terms of tank size and configuration.
Future-Proofing: When designing the layout of fermentation tanks, it’s wise to leave space for additional tanks or larger replacements. Planning for expansion from the outset can save time and costs associated with retrofitting or redesigning the brewery later.
Tank Utilization: Efficient use of tank space is critical for scalability. This includes optimizing the tank’s fill rate and ensuring that tanks are neither underutilized nor pushed to their limits, which could compromise product quality.
Interconnectivity: Designing tanks with interconnectivity in mind can also enhance scalability. This includes planning for shared utilities like glycol lines for cooling, CO2 lines, and CIP (Clean-in-Place) systems, which can be extended to new tanks as the brewery expands.
Versatility: Selecting tanks that can be used for multiple stages of production—such as both fermentation and conditioning—can increase flexibility and scalability. This approach allows breweries to adapt to changing production needs without requiring significant new investments.
