ISSUE FOCUS 44 FEED & ADDITIVE MAGAZINE March 2026 due, enable fast cleaning, and reduce carryover risk through proven hygienic design details. 3. Traceability and recipe logic: Use MES functions (traceability, recipe sequencing) to reduce cross-contamination risk in daily operation. 4. Conditioning control: Manage not only temperature and time, but also moisture - because moisture strongly influences hygienization performance. 5. Digital control for stability: Use automation and real-time data to reduce variability, manual interventions, and downtime. CONCLUSION Feed safety is increasingly shaped by a combination of stricter requirements, more variable raw materials, and more sensitive bioactive ingredients. In this environment, consistent results depend on more than individual machines. The strongest safety outcomes come from integrated solutions: hygienic equipment design, validated cleaning and sorting, controlled conditioning, and digital systems that stabilize production and support traceability. With advanced cleaning and sorting, hygienically designed machines and plants, and automation and digital services that enable precise control (especially of moisture), modern processing technologies can help feed mills raise their safety level while protecting throughput and product quality. About Gero Zimmermann After completing his doctorate in electrical engineering, Gero Zimmermann held various technical management positions at a global manufacturer of electronic components and systems. Since joining Bühler in 2011, he has played a key role in the development, industrial implementation, and business development of modern processing technologies for the animal feed industry. His particular focus is on sustainability and digitalization, helping to ensure the industry’s longterm competitiveness. Photo: Bühler Group
