The new Nutrex 7 Series was built on more than 40 years of Bühler extrusion expertise and designed in line with EHEDG hygienic design guidelines, it focuses on improving food and feed safety, production flexibility, cleanability, and process stability. Its hygienic stainless-steel architecture, wet-cleanable systems, and validated cleaning concepts help reduce contamination risks while supporting audit-ready production. Cleaning times can be reduced by up to 50%, helping minimize downtime and improve equipment availability.
The system’s modular, scalable platform supports flexible layouts and makes it easier to adapt to new products, capacity changes, and regulatory requirements. For operators, intuitive controls, guided workflows, clear visualization, and automated functions simplify daily use, reduce dependency on specialized expertise, and shorten training time.
Process performance is enhanced by a hygienic two-stage preconditioner, which improves control of moisture, temperature, and residence time. This supports better product homogeneity, more stable extrusion, and up to 50% lower mechanical load on the extruder. The patented cyclone cutting process further improves cutting consistency, visibility, hygienic product handling, and uptime.
The Nutrex 7 Series also includes a future-ready automation platform with a 24-inch wet-cleanable HMI, real-time process visualization, user-defined KPIs, browser-based operation, and integrated food safety features.
Overall, Nutrex 7 Series is positioned as a cleaner, smarter, and more flexible extrusion solution that helps producers improve efficiency, maintain consistent quality, and prepare for future production demands.
