Twin screw extruder for pet and aquatic feed
Achieve exceptional cooking precision with our twin screw extruder, designed to enhance product consistency and expand ingredient possibilities through innovative steam injection and reduced mechanical energy dependency.

Processes Complex Food and Feed Formulations
The Thermal Twin Twin Screw Extruder from Wenger revolutionizes the production of textured vegetable proteins, meat analogs, and diverse aquatic feeds through its enhanced steam injection capabilities. Utilizing angled steam injector ports, it ensures up to four times more steam is evenly distributed, achieving a 14:1 thermal to mechanical energy ratio, crucial for consistent cooking processes. Ideal for applications like soy protein chunks and pet kibble with fresh meat inclusion, it efficiently handles various formulations with reduced wear and energy costs. The machine supports a range of capacities, controlled through a PLC system, allowing seamless integration into automated production lines. Available in stainless steel for food safety compliance, it minimizes maintenance with a hygienic design featuring minimal seams and dust-tight structures. Customize this extruder with ancillary equipment like the High Intensity Preconditioner to optimize hydration and mixing, supported by Wenger’s robust engineering network.
