Andritz showcased ExMax S1021, its latest extrusion innovation, at Victam LATAM 2025. The new extruder responds to the growing demand for safer, more sustainable pet food and aqua feed, the company points out.
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.”
BUILT FOR TODAY’S CHALLENGES
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.
Key benefits have been explained as including:
Food safety: Stainless steel hygienic design for faster cleaning and compliance with safety standards.
Product consistency: Patented DensiFlex™ system for precise density control, faster startup and shutdown.
Flexibility: Capable of processing a wide variety of feed formulations with ease.
Reduced downtime: Curved knife housing with automatic adjustment to minimize residue buildup.
