Why choose a cylindrical-conical tank for brewing beer?

Controlled fermentation is the key to exceptional beer. For professional brewers, the choice of equipment is decisive in guaranteeing consistent quality and optimising each stage of the brewing process. That's where the advantages of cylindro-conical tanks come into play, equipment that has become indispensable in modern breweries. Thanks to their ingenious design, these tanks facilitate yeast separation, reduce losses and improve the clarity of the final product.

In this article, we'll explore why these stainless steel tanks are an indispensable asset for brewers, whether they're running a microbrewery or a large production operation. You'll discover how their unique design optimises brewing and ensures more efficient fermentation, while making maintenance and waste management easier. Get ready to plunge into the world of cylindro-conical tanks and understand why they are a strategic choice for professionals in the sector.

More efficient fermentation

In beer brewing, fermentation control is a key element in guaranteeing quality production. Thanks to their specific design, stainless steel cylindro-conical tanks enable more homogeneous and better-controlled fermentation, a major advantage for professional and craft brewers.

Easy yeast recovery: an optimised process

In the brewing process, yeast management plays a key role in the final quality of the beer. Effective fermentation relies on a clear separation between the liquid and the sediment, a step that is often complex with traditional tanks. Thanks to their ingenious design, cylindrical-conical tanks make this task easier by allowing the yeast to settle naturally and optimally. Their conical shape gradually directs the sediment towards the bottom of the tank, where it accumulates without interfering with the liquid part of the brew.

One of the major advantages of this technology is the significant reduction in beer losses. With conventional fermentation systems, yeast and suspended particles remain mixed with the wort, making it difficult to separate them and resulting in considerable wastage during racking. With a cylindrical-conical tank, this problem is largely avoided. The clarified beer can be extracted without any undesirable residue, guaranteeing greater profitability for the brewer.

Another essential advantage is that the yeast can be recovered and reused for subsequent brews. In a brewery, the quality of the yeast determines not only the taste and aroma of the beers, but also the consistency between each production run. Optimised yeast management helps to stabilise the taste profile while reducing the cost of buying new strains. The accumulation of yeasts in the cone facilitates their extraction in a sterile environment, preserving their vitality and their ability to be used several times without loss of performance.

Finally, the clear separation of wort and sediment contributes directly to improving the clarity of the beer. Beer that is cloudy or contains undesirable deposits can detract from the consumer experience and impact on a brewery's image. Thanks to a cleaner, better-controlled fermentation process, cylindrical-conical tanks offer a clearer end product, limiting the need for additional filtration. Adopting these tanks is therefore a strategic choice for any brewer looking to optimise their production process while guaranteeing high-quality beer.

Better management of pressure and temperature

Fermentation is a delicate phase of brewing, where every variation in temperature and pressure can have a direct impact on the taste, texture and stability of the beer. Inadequate regulation can lead to incomplete fermentation, unbalanced aromas or undesirable defects in the final product. It is precisely to avoid these hazards that cylindro-conical fermenters stand out for their ability to offer optimal control of fermentation conditions.

One of the major challenges for a brewer is to maintain a stable temperature throughout the process. Excessive heat can accelerate yeast activity uncontrollably, producing undesirable alcohols and overly pronounced aromas. Conversely, too low a temperature slows fermentation and can alter the expression of esters and phenols, essential components of the flavour profile of many beers. Thanks to their integrated cooling jackets, the cylindrical-conical tanks allow precise temperature control. This system promotes homogenous fermentation, adapted to the specific requirements of each recipe, whether for an ale fermenting at moderate temperatures or a lager requiring rigorous cold control.

As well as temperature, pressure management plays a key role in the success of a brew. Well-controlled pressure ensures optimum natural carbonation, avoiding excess CO₂ which could give too pungent a mouthfeel or, conversely, a lack of effervescence which would affect the perception of the finished product. Cylindro-conical fermenters are designed to support and adjust internal pressure through safety valves and regulating valves, allowing brewers to modulate carbonation according to the desired beer style. This precision is particularly appreciated for beers filled directly into tanks, where a perfect balance between dissolved gas and texture is required.

Another major advantage of these tanks is their hermetic design, which considerably reduces the risk of contamination. Unlike open or poorly insulated fermenters, where undesirable micro-organisms can spoil the fermentation process, cylindrical-conical tanks provide a closed, controlled environment. This tight seal enhances the microbiological stability of the brew, guaranteeing safer, more reproducible fermentation.

Thanks to their precise temperature control, effective pressure regulation and hermetically sealed design, these tanks are an invaluable asset for brewers looking to optimise their fermentation process. By limiting temperature variations, stabilising carbonation and reducing the risk of contamination, they ensure more regular production, consistent quality and better control of the finished product.

Robust, hygienic equipment

In the brewing sector, the hygiene and durability of equipment are essential criteria for guaranteeing efficient production that complies with health standards. Stainless steel cylindro-conical tanks are exceptionally resistant and easy to maintain, meeting the requirements of both professional and craft breweries.

Corrosion-resistant 304 stainless steel

304 stainless steel, used in the manufacture of conical fermentation tanks, is renowned for its strength and resistance to corrosion. This alloy is ideal for use in brewing, as it does not deteriorate under the effects of humidity, temperature variations or aggressive cleaning products.

📌 Why choose 304 stainless steel for a brewing vessel ?
✔ Increased durability, preventing premature deterioration of the equipment.

✔ Total neutrality: no transfer of taste or odour into the beer.
✔ Adapted to health standards: stainless steel is the material of choice for the food industry.

📍 Example : ARSILAC models 006808, 006641 and 006642 are designed in 304 stainless steel, guaranteeing optimum resistance to intensive cleaning and the acidity of fermenting musts.

Easy to clean with removable wash balls

Equipment maintenance is a major issue in brewing. A poorly cleaned tank can lead to microbial contamination and alter the quality of the brews. Cylindro-conical fermenters are designed to simplify this process, thanks to built-in removable wash balls.

More precise and efficient brewing

Optimising the brewing process is a priority for professional brewers, whether in microbreweries or industrial production. Stainless steel cylindro-conical tanks offer greater precision at every stage of fermentation, guaranteeing better quality beer with optimised yields.

Total emptying system for better must recovery

The efficiency of brewing depends not only on fermentation, but also on the ability to extract the wort optimally. Every litre of beer produced represents an investment in raw materials, time and energy, making wort recovery essential to maximising the profitability and quality of the brew. Cylindro-conical fermenters are designed to extract all the fermented liquid, minimising losses and guaranteeing optimum yield.

A traditional tank, with its flat or slightly domed structure, can retain a significant quantity of residual must, trapping yeast and sediment at the bottom of the container. This wastes product and increases the need for additional handling to recover the liquid that can still be used. Conversely, the conical shape of cylindrical-conical tanks makes it easier to concentrate sediment to a single point, enabling more efficient draining. Thanks to their gently sloping design and the addition of a 90° drain elbow, as on ARSILAC models, the entire must can be extracted without leaving any unwanted residue.

This total emptying process is not just a question of yield, it also plays a key role in the hygiene and safety of production. By completely draining the must and preventing the build-up of deposits inside the tank, the risk of bacterial contamination is greatly reduced. Incomplete extraction encourages the stagnation of residues that can affect the quality of subsequent brews and require more intensive cleaning. By completely emptying the contents, cylindrical-conical fermenters guarantee a cleaner, more stable fermentation environment, limiting undesirable variations from one brew to the next.

Optimising brewing also involves more efficient economic management. Every litre of beer lost represents an additional cost, whether in raw materials or labour time. Maximum wort recovery reduces these losses and increases the yield per brew, a significant advantage for craft and industrial breweries. With cylindro-conical tanks fitted with high-performance draining systems, every production run becomes more profitable and more controlled, while guaranteeing beer of impeccable quality.

Clear draw on the cone for clearer beer

One of the hallmarks of a quality beer is its clarity and visual stability. A crystal-clear beverage, free from suspended residues, reflects not only the care taken in its production, but also the mastery of the fermentation process. This is where conical fermentation tanks play a decisive role, as their specific design encourages natural separation of sediment and yeast. By gradually concentrating the solid particles towards the bottom of the cone, they produce a purer liquid, without altering the beer's aromas or texture.

The main advantage of clear draught is that it preserves the organoleptic qualities of the brew. Yeast residues in suspension can sometimes give rise to undesirable tastes, altering the balance of flavours and attenuating the desired aromatic finesse. By facilitating the elimination of these particles, the clear draught system integrated into the cylindro-conical fermenters guarantees a beer with clean, precise flavour notes, and better enhancement of the selected malts and hops. This process is particularly advantageous for beer styles requiring a high degree of transparency, such as lagers, pilsners or certain IPAs.

In addition to its impact on sensory quality, this technology also optimises the packaging process. Clearer beer means less downstream filtration, reducing the workload and speeding up bottling or kegging. Less filtration also means less waste, guaranteeing better brew profitability. Breweries looking to improve their productivity while maintaining artisanal quality therefore have a real advantage in adopting fermenters equipped with a clear draught system.

ARSILAC models incorporate a precise stainless steel butterfly valve sampling system, designed to ensure clean and controlled extraction of the fermented liquid. This configuration allows brewers to draw off only the clarified part of the brew, without stirring up the sediment that has accumulated at the bottom of the tank. The result is a more stable beer, both visually and in terms of taste, with a consistency and brilliance that will appeal to amateurs and professionals alike.
