Extruder for aquatic feed production
Efficiently produce a wide range of aquatic and pet feed with precise control over pellet sizes and densities, ensuring optimal nutrition retention and water stability for demanding aquaculture environments.

Produces Consistent Aquatic and Pet Feed Pellets
The AquaFLEX™ Twin Screw Extruder, part of Wenger’s FLEX™ series, is engineered for manufacturers in the aquatic and pet feed industries requiring precise control over pellet size, density, and nutritional retention. This system employs twin screw technology to address the challenge of producing small-sized pellets that maintain high-density characteristics. The AquaFLEX™ excels at versatility, producing floating, sinking, and slow-sinking feed for a variety of species, including shrimp, salmon, and trout.
With the capability to process up to 13,000 kg/hr and pellet sizes ranging from 0.6mm to 10mm or more, the AquaFLEX™ combines high throughput with superior flexibility. Designed for automated, continuous operations, it integrates seamlessly into production lines, offering customization through Wenger’s High Shear Conditioner, High Intensity Preconditioner, and other supportive systems. By optimizing motor speeds, it ensures energy-efficient operation, while its stainless steel construction provides robust, corrosion-resistant durability. Ideal for facilities demanding high-volume, reliable feed production, this extruder ensures compliance with industry standards and supports easy maintenance with features like a CIP system for efficient cleaning processes.
