Driven by the craft beer craze, more and more brewing enthusiasts are moving from home brewing to commercial production. In this process, choosing the right equipment is crucial, and the conical бродильный чан has gradually become the first choice of brewers due to its unique design and function. But for beginners and brewers about to expand their production scale, is the conical fermentation tank worth investing in? What are its advantages and disadvantages compared with traditional fermentation tanks? What issues should be paid attention to before purchasing? This article will provide a comprehensive analysis of this.
A conical fermenter is a beer fermentation equipment with a conical bottom, commonly used in commercial and craft brewing. Unlike traditional cylindrical or barrel fermenters, its bottom is at an angle of 60° or steeper, which facilitates the automatic separation of sediment and yeast.
Conical fermenters are usually made of stainless steel or high-strength plastic and are equipped with drain valves, temperature control devices, pressure regulation systems, and other functions to meet the brewing needs of different scales. Whether it is a small home brewer or a large craft brewer, you can choose the appropriate specifications according to your production scale.
Преимущества конических бродильных резервуаров
Efficient yeast separation and recovery
During the fermentation process, yeast will settle to the bottom of the tank, and the conical design allows these precipitated yeasts to be collected in a centralized manner without being mixed into the finished beer. This not only improves the clarity of the beer but also recovers healthy yeast for subsequent brewing, thereby reducing yeast costs and maintaining consistency between batches.
Reduce oxidation risk and improve beer quality.
Traditional бродильные ёмкости are easily exposed to the air when transferring beer, causing oxidation and affecting the taste. The conical fermentation tank allows primary and secondary fermentation to be carried out directly in the same container, avoiding frequent transfers, reducing oxygen contact, and making the beer fresher and more stable.
Suitable for a variety of brewing styles
Whether it is ale, lager, IPA, or stout, the conical fermentation tank can adapt to different fermentation needs. Its temperature control function can also help brew low-temperature fermented beer, providing greater flexibility.
Easier cleaning and maintenance
Conical fermentation tanks are usually made of stainless steel, which has strong corrosion resistance and a smooth surface that is not easy to hide dirt. Many models are equipped with a CIP system that allows for automatic cleaning, reducing the workload of manual cleaning and improving production efficiency.
Carbonation can be performed on the same equipment
Some conical fermenters support pressurized fermentation, which can be directly carbonated during the fermentation process, reducing additional carbonation steps, improving efficiency, and improving the fineness of the beer foam.
Conical fermentation tank investment return analysis
The conical fermentation tank is suitable for the following groups of people:
- Home brewers: hope to improve brewing quality, reduce contamination risks, and try more advanced brewing techniques.
- Craft brewery entrepreneurs: plan to expand production scale, and improve efficiency and product consistency.
- Commercial wineries: hope to optimize the brewing process and reduce long-term production costs.

Types of Conical Fermenters and Their Features
Standard Conical Fermenters
Standard conical fermenters are the most basic type. They feature a single-wall construction and do not offer any additional temperature control. While they may lack some of the advanced features of other types, they remain a popular choice for homebrewers and small breweries due to their simplicity and affordability. With standard conical fermenters, brewers still benefit from the conical design, which allows for easy separation of lees and yeast, resulting in cleaner, clearer beer. Additionally, the conical design promotes yeast health and fermentation efficiency.
Jacketed Conical Fermenters
Jacketed fermenters take the fermentation process to the next level by providing precise temperature regulation. These fermenters come with a cooling jacket that surrounds the conical vessel, allowing brewers to control the temperature of the fermenting beer. This feature is particularly beneficial for controlling fermentation and achieving optimal yeast activity. By maintaining a constant temperature throughout the fermentation process, brewers can ensure that the yeast is working optimally, resulting in better flavor and overall beer quality.
Insulated Conical Fermenters
Insulated fermenters are an excellent choice for brewers who ferment in environments with fluctuating temperatures. These fermenters are designed with a layer of insulation that helps maintain a steady temperature throughout the fermentation process.
The insulation acts as a barrier, preventing outside temperature fluctuations from affecting fermentation. This is especially important during cold winters or hot climates, where maintaining a constant temperature can be difficult.
By using an insulated conical fermenter, brewers can rest assured that their beer is fermenting at the optimal temperature regardless of the outside conditions.
Conical Fermenters vs. Other Fermentation Vessels
- Glass Carboys and Glass Jugs: Conical fermenters are superior in terms of use, cleaning, and sediment removal. Glass Carboys and Glass Jugs are more challenging to clean and transfer beer without messing with sediment.
- Barrels and Plastic Fermenters: Conical fermenters provide better temperature control and reduce oxygen exposure compared to plastic fermenters, which improves beer quality.
- Flat Bottom Fermenters: While conical and flat bottom fermenters serve the same purpose, the conical design allows for better sediment collection and yeast management.
- While the choice ultimately comes down to personal preference and budget, conical fermenters are often the preferred choice for brewers.
Common problems and solutions for conical fermentation tanks
The initial cost is high, is it worth investing?
If you only brew occasionally and have a limited budget, you can choose a plastic or stainless steel conical fermentation tank with a smaller capacity (10L-50L), which is relatively cheap. But if it is commercial production or long-term brewing, it is worth investing in a high-quality stainless steel conical fermentation tank because it is more durable and can improve long-term benefits.
Does it require special cleaning methods?
Stainless steel conical fermentation tanks can be cleaned with an alkaline cleaner (PBW) + acid disinfectant (StarSan), and at the same time use a CIP system or high-pressure water washing. Compared with traditional fermentation tanks, it requires less cleaning work, but it still requires regular maintenance.
Is it suitable for low-temperature fermentation?
Yes, most conical fermentation tanks are equipped with cooling jackets or temperature control devices, which can accurately control the fermentation temperature and are suitable for low-temperature fermentation of lager beer. Home brewers can also use temperature control boxes or refrigerators for control.
How to avoid blockage caused by excessive precipitation?
When using a blowdown valve, slowly discharge the sediment in batches to avoid yeast mud or hop residue clogging the valve. For larger commercial fermenters, a cyclone sedimentation device can be installed to help separate impurities.
