NEWS FEED & ADDITIVE MAGAZINE October 2025 9 International technology group Andritz launched its latest extrusion innovation – the ExMax S1021 – at the VICTAM LATAM event, held from September 16-18, 2025, in São Paulo, Brazil. Andritz highlights that the new extruder responds to the growing demand for safer, more sustainable pet food and aqua feed by helping producers achieve consistently high-quality nutrition, improved food safety, and greater efficiency, while reducing operating costs and unplanned downtime. Developed in collaboration with industry producers, the ExMax S1021 reportedly combines a hygienic design with advanced automation to make production cleaner, more reliable and easier to control, while minimizing waste. “The ExMax S1021 is not just about capacity – it’s about giving producers greater control, cleaner operations, and consistently higher product quality,” said Danny Cummins, Head of Product Management at Andritz Feed & Biofuel. “Producers worldwide are under pressure to deliver safer, more sustainable feed at lower cost. This technology is designed to meet these demands and help them remain competitive in fast-growing markets like those in Latin America.” The ExMax S1021 features the patented DensiFlex™ system, which automates control of cooking and expansion to ensure product uniformity. Its hygienic, stainless-steel design simplifies cleaning and minimizes the risk of cross-contamination — two key concerns for producers of pet food and aqua feed, Andritz remarks.

Aker QRILL Company states that this is the first study on the impact of QRILL Aqua from a commercial-scale field trial during the seawater transfer period. The seawater transfer period is a known bottleneck in salmon farming, marked by appetite suppression, osmoregulation stress, increased disease risk, and higher mortality rates. Industry figures show that a large share of losses occur during the first months at sea, creating both economic and fish welfare concerns. “By combining Skretting’s feed expertise with QRILL Aqua’s proven nutritional benefits, we were able to test under real farming conditions. This is a strong example of how collaboration can advance solutions for the industry,” expresses Kjetil Berge, R&D Leader, Skretting. The 116-day trial, conducted at a commercial salmon farm in Harstad, Norway, compared a commercial diet containing 15% fishmeal to one in which 10% krill meal (QRILL Aqua) was used, thereby reducing the fishmeal by one-third. The study reports that salmon fed the QRILL Aqua diet: • Consumed 3% more feed, • Achieved 22% lower mortality, • Exhibited 4.8% higher growth.
