Conical Fermenter Tank
Brewing beer is a time-honored tradition, and while the process has stayed relatively the same over centuries, the equipment has evolved dramatically. One of the most significant innovations in modern brewing equipment is the conical fermenter tank. Whether you are a homebrewer or managing a commercial brewery, understanding the conical fermenter tank and how it impacts your brewing process can help you produce higher-quality beer. In this article, we’ll delve deep into every aspect of conical fermenters, including types, processes, costs, advantages, installation, maintenance, and supplier selection.
Overview of Conical Fermenter Tanks
The conical fermenter tank is a cylindrical vessel with a cone-shaped bottom, designed to streamline the fermentation process in beer brewing. Its design allows for a cleaner, more efficient separation of yeast and sediment from the liquid. This enhances the clarity of the beer and simplifies the process of removing yeast or transferring the liquid into another vessel. These tanks are used in both small-scale homebrewing and large-scale commercial brewing operations.
Unlike flat-bottom fermenters, conical fermenters offer precise control over the brewing process, reducing the risks of contamination and improving the consistency of the beer. They also allow for dry hopping, yeast harvesting, and easy trub separation, which are vital steps for producing high-quality craft beers.
Equipment Guide: What is a Conical Fermenter Tank?
Conical fermenter tanks serve as both the primary fermenter and, in some cases, the secondary fermenter. Their unique design allows yeast, trub, and sediments to settle at the cone’s bottom while the liquid remains on top. This structure simplifies the removal of unwanted materials from the beer and provides a cleaner transfer to the next stage of the brewing process.
Key Features of a Conical Fermenter Tank:
- Conical Shape: The cone bottom slopes down to a central valve or drain where sediment collects, allowing easy separation from the brew.
- Material: Most conical fermenters are made from stainless steel because of its durability, non-corrosive properties, and ease of sanitation.
- Pressure Control: Many models come equipped with pressure relief valves to ensure safety and provide control over carbonation levels.
- Temperature Regulation: Some models feature built-in cooling jackets or are compatible with external temperature control systems to keep the fermentation process consistent.
Types of Conical Fermenter Tanks
Conical fermenters come in various types, each catering to different needs based on scale, budget, and operational complexity. Here’s a breakdown of the common types available:
| Type of Conical Fermenter | Material | Capacity | Best For | Price Range |
|---|---|---|---|---|
| Stainless Steel Conical Fermenters | Stainless steel (SS304/SS316) | 1 gallon – 1000+ gallons | Commercial breweries, serious homebrewers | $500 – $10,000+ |
| Plastic Conical Fermenters | High-quality food-grade plastic | 1 gallon – 50 gallons | Homebrewing, beginners | $50 – $500 |
| Hybrid Fermenters | Stainless steel with plastic components | 1 gallon – 300 gallons | Small-scale brewing | $300 – $2000 |
| Pressurized Conical Fermenters | Stainless steel with pressurization capabilities | 10 gallons – 1000+ gallons | Carbonation control, high-end commercial setups | $2,000 – $15,000+ |
Each type offers different benefits based on your brewing needs, space, and budget. Stainless steel options are durable and ideal for long-term brewing investments, while plastic fermenters can be more accessible for home brewers who are just starting out.
Brewing Process Using a Conical Fermenter
Brewing beer with a conical fermenter adds several layers of convenience to the traditional brewing process. Let’s walk through the general brewing process while highlighting how a conical fermenter enhances each step.
- Wort Transfer: After boiling the wort, it is transferred into the conical fermenter to start the fermentation process. The top part of the fermenter is sealed to avoid exposure to contaminants.
- Fermentation: Once yeast is added to the wort, fermentation begins. A conical fermenter allows for easy temperature regulation through external cooling systems or insulation, ensuring stable fermentation.
- Trub Separation: As fermentation progresses, yeast and other solids (trub) settle at the bottom of the cone. A valve at the base allows brewers to remove the trub without disturbing the beer. This results in a cleaner and clearer final product.
- Yeast Harvesting: The conical design makes it easier to collect and reuse yeast. Simply drain the settled yeast from the bottom valve.
- Secondary Fermentation/Dry Hopping: If you want to introduce additional flavors or perform a secondary fermentation, it’s simple to add hops or other ingredients through the top of the fermenter.
- Transfer or Bottling: Once fermentation is complete, the beer is either transferred to another vessel or bottled directly from the fermenter. Since the yeast and trub have already been separated, this process is smoother compared to traditional fermenters.
Design and Customization of Conical Fermenter Tanks
Conical fermenter tanks come in a variety of designs and can be customized based on brewery needs. Some factors to consider when selecting a design include capacity, available space, temperature control features, and the need for automation.
| Design Aspect | Details |
|---|---|
| Capacity | Conical fermenters range from 1 gallon for homebrewers to 1000+ gallons for commercial use. |
| Space & Layout | Vertical, compact designs optimize space, while larger models may require dedicated brewing areas. |
| Material | Stainless steel is preferred due to its durability and ease of cleaning. Plastic options are lightweight but less durable. |
| Customization Options | Cooling jackets, pressurization features, additional valves, and automation systems are some of the customizable aspects. |
| Temperature Control | Some fermenters come with built-in jackets for glycol cooling systems, while others may need external temperature control systems. |
Choosing the right conical fermenter design is crucial for achieving consistency and efficiency in your brewing process. If you’re running a large brewery, automation features might be essential for scaling production efficiently.

Installation, Operation, and Maintenance of Conical Fermenter Tanks
Installation:
Installing a conical fermenter tank requires careful planning. Consider the available space, the need for temperature control systems, and the proximity to other brewing equipment. Stainless steel fermenters often need additional setup for cooling jackets and pressure-relief valves.
Operation:
Operating a conical fermenter is straightforward but requires attention to detail. After transferring wort into the fermenter, make sure it’s sealed properly to prevent contamination. Regularly monitor temperature, pressure, and fermentation activity.
Maintenance:
Maintaining a conical fermenter involves thorough cleaning after each use to prevent any contamination in subsequent brews. Stainless steel models are easier to sanitize and typically require cleaning solutions such as PBW (Powdered Brewery Wash) or caustic soda to ensure all residue is removed. Plastic models may require gentler cleaning to avoid scratches that can harbor bacteria.
| Process | Details |
