Nutrex 7 Series is our next-generation twin-screw extrusion platform for the food and feed industry. Designed according to EHEDG hygienic design guidelines, delivering highest food and feed safety standards - backed by over 40 years of proven technology.
The Nutrex 7 Series is designed according to EHEDG hygienic design guidelines, with stainless-steel construction, wet cleanable systems, and validated cleaning concepts enabling a cleaning time reduction of up to -50 %. Hygiene is embedded in the machine architecture – not added through procedures – reducing contamination risks, audit pressure, and total cost of ownership.
The Nutrex extrusion machine control adapts to your process - not the other way around. This unified, hygienic machine-to-plant automation platform features a 24″ wet-cleanable HMI with a new real-time process visualization, intuitive operator interface, user defined KPIs, browser-based operation, and built-in food safety. Ready for today's demands and tomorrow's growth.
The hygienic two-stage preconditioning ensures defined moisture, temperature and residence time – improving homogeneity, reducing extruder torque and enabling stable, energy efficient extrusion with up to 50% lower mechanical load. The patented cleaning lance concept achieves highest levels of hygiene and enables effective internal cleaning.
The new patented cyclone cutting process delivers stable cutting patterns, high visibility and hygienic product handling. Designed for safety, fast cleaning and consistent quality, it reduces deposits, wear and downtime while supporting reliable downstream processing.
Nutrex 7 Series builds on 40 years of Bühler twin-screw extrusion DNA. It combines unchanged, proven process geometry with a completely new machine design – delivering familiar process behavior, recipe compatibility and fast scale up, ensuring continuously high levels of end-product quality.
As the first prototype customer of the Nutrex 7 Series extrusion system, we were closely involved in the development process. The collaboration with Bühler was pleasant and effective. We were particularly impressed by the easy integration into our existing line as well as the significantly simplified handling. The intuitive control system makes day-to-day operation noticeably easier.
