OPTIFERM – BEER FERMENTATION OPTIMIZATION SYSTEM

EXTERNAL HEAT EXCHANGE AND 360° MIXING

The core of OptiFerm is the combination of active recirculation, external heat exchange and 360° mixing.

The external heat exchanger provides efficient temperature control, while the 360° mixer ensures that the product is distributed evenly inside the tank. This helps eliminate cold and hot zones, supports efficient yeast suspension and allows the brewery to respond faster when process conditions need to change.
The result is a more controlled fermentation process with lower energy consumption, shorter cooling times and better use of the existing tank capacity.

KEY BENEFITS

Lower energy consumption

OptiFerm reduces energy consumption by improving the efficiency of heat transfer during fermentation.
By using external heat exchange and active recirculation, the system minimizes energy losses and improves the overall efficiency of the fermentation process. OptiFerm is also well suited for integration with heat pumps, enabling further reductions in total energy consumption and CO₂ emissions.

Faster cooling and shorter process time

Efficient cooling and fast temperature response make it possible to move more quickly between process phases.
OptiFerm can reduce cooling time significantly and support a shorter overall fermentation process. This improves the utilization of the fermentation department and helps the brewery increase output from the existing tank setup.

Increased fermentation capacity

For many breweries, fermentation tank capacity is a major production bottleneck.
By reducing cooling time and overall process time, OptiFerm can increase the utilization of existing fermentation capacity. This allows breweries to produce more without necessarily adding more tanks.

Homogeneous temperature throughout the tank

Traditional fermentation setups can create temperature differences inside the tank.
OptiFerm helps create a more uniform temperature distribution throughout the fermenter. This improves process control and creates more stable conditions for yeast activity, fermentation performance and product quality.

Efficient yeast suspension

The 360° mixer keeps yeast in homogeneous suspension during the fermentation process.
This supports better yeast utilization, more stable fermentation conditions and improved process performance. Efficient yeast suspension can also contribute to faster diacetyl reduction and better use of the brewery’s fermentation capacity.

Optimized yeast management

OptiFerm can support improved yeast management and product consistency.
Better yeast suspension and controlled process conditions can help improve yeast health and reduce yeast consumption per batch. Optimized yeast extraction can also reduce the load on centrifuges and filtration systems.
Controlled aeration can be integrated directly into the recirculation loop when required by the process.

Suitable for high-gravity brewing

OptiFerm is well suited for high-gravity brewing applications.
The combination of active recirculation, efficient mixing and precise temperature control supports demanding fermentation processes where yeast performance, process stability and cooling efficiency are critical.

Low- and non-alcoholic beer fermentation

OptiFerm also supports the production of low- and non-alcoholic beer.
By using selected yeast strains that only metabolize monosaccharides, breweries can produce beers with 0.5% and even 0.0% ABV directly in the fermentation process.
This can reduce or eliminate the need for expensive dealcoholization equipment. Production of 0.0% ABV beer requires oxygen injection within the circulation loop.

HYGIENE, CIP AND STERILIZATION

OptiFerm can also improve cleaning and hygiene routines in brewery production.

CIP cleaning can be performed directly through the 360° mixer, helping to ensure full cleaning coverage inside the tank. This can reduce the need for separate internal CIP equipment and help lower water, chemical and cleaning time consumption.

For tanks without cooling jackets, heat sterilization becomes possible, as the tank design is mechanically simpler and less exposed to thermal stress from traditional jacket construction.

BUILT FOR NEW AND EXISTING BREWERY INSTALLATIONS

OptiFerm is a flexible and scalable fermentation optimization solution for modern breweries.

The system can be adapted to both new installations and existing tank farms, making it relevant for breweries that want to improve fermentation efficiency, reduce operating costs, increase capacity, optimize yeast management and support more sustainable production strategies.

Whether the objective is higher output, better process control, reduced energy consumption or new possibilities within low- and non-alcoholic beer, OptiFerm provides a practical and technically advanced approach to brewery fermentation.
