HERM MACHINERY
The H Series Twin-Screw Feed Extruder is engineered to produce a wide variety of floating, sinking, and slow-sinking aquatic feeds. Designed to handle complex and demanding formulations, it produces high-quality feed pellets for species like California seabass and grouper. With the ability to process small particle sizes down to 0.6mm and handle low-starch, high-protein, and high-fat recipes, this extruder is a perfect choice for modern, high-performance aquaculture.
The system can be equipped with vacuum extraction, pressure density control technologies, and a fully automated control system to ensure operational stability and consistent product quality.
