New food fermentation, where microorganisms such as yeast, bacteria and fungi convert raw materials into valuable food ingredients, is becoming an increasingly important capability for food and ingredient producers. As the industry looks to diversify ingredient sourcing and improve resource efficiency, producers are moving from pilot testing to industrial-scale production. These companies are therefore seeking systems that deliver consistent performance while reducing variability and operational burden.

Tetra Pak Bioreactor RF is a fermentation vessel designed to maintain stable conditions while providing operators with actionable process insight. From pilot validation and first industrial runs through to full-scale production, the system delivers repeatable performance without increasing operational complexity.

“Industrial fermentation succeeds when performance is repeatable, day after day,” says Rafael Barros, director of the New Food Business Stream at Tetra Pak. “Tetra Pak Bioreactor RF is designed to reduce operational risk and remove complexity, helping operators stay in control.”

Tetra Pak Bioreactor RF is pre-assembled and factory-tested, enabling faster installation and commissioning, while reducing disruption to production planning. Its integrated platform design removes the need for separate support structures, lowering installation costs and complexity.

At the core of Tetra Pak Bioreactor RF is a patented magnetic agitation system that removes the need for mechanical seals, a common source of contamination risk and process instability in conventional designs. Unlike traditional magnetic agitators, which can struggle to maintain power as vessel size increases, Tetra Pak’s patented system is designed to maintain power and oxygen transfer across the full size range. This helps maintain stable process conditions and reduce the risk of batch loss, typically valued at around €1,000 per m³.

High levels of automation further simplify operation. Self-adjusting control functions help stabilize conditions as processes evolve, reducing the need for manual intervention. Combined with predefined operating strategies and integrated data monitoring, this enables operators to run processes more efficiently and with greater visibility.

Available in sizes from 10 to 50,000 liters, all Tetra Pak Bioreactor RF units use the same design platform, control logic and operating philosophy. This consistency simplifies operator training and day-to-day operation across sites and production scales. The modular configuration also allows producers to adapt alarm thresholds, impellers and configurations as process needs evolve, without adding unnecessary system complexity..
