Twin screw extruder for pet and aquatic feed
Creating high-quality pet food or aquatic feed requires advanced extrusion techniques to ensure optimal cooking, texture, and ingredient integration. Challenges include achieving consistent cook rates, reducing wear costs, and incorporating higher levels of meat or slurry in the recipes.
Increase steam injection and product innovation
The Thermal Twin from Wenger is a twin screw extruder designed to remove product barriers through enhanced steam injection. With angled steam injector ports oriented in the direction of material flow, it allows for up to four times more steam injection into extrusion zones, evenly distributed over the barrel length. This results in a thermal to mechanical energy ratio of 14:1 and operating costs comparable to single screw technology. The extruder achieves more than 90% cook rates consistently, improving upon values in the 80s typically seen with conventional extruders without changing product density or palatability. Suitable for both pet food and aquatic feed, the extruder supports high fresh meat inclusion, semi-moist product production, and flexible ingredient options. Available in models TT-760 and TT-3630, with capacities up to 10,000 kg/hr.
