Extruders for aqua feed production

When producing aqua feed, it is essential to consider the feed characteristics for the specific species of fish and shell fish. ANDRITZ offers unique, high-capacity extrusion lines for the production of all kinds of feed for fish and shell fish. The ANDRITZ extruders ensure that the feed has the right physical properties – giving it the correct sinking attributes according to where in the water the feed should be accessed.

ANDRITZ single screw extruders represent state-of-the-art technology, ensuring high quality aqua feed at minimum operating costs.

The patented ANDRITZ ECS is a reliable system for accurate control of expansion for any extruded product. The ECS controls sinking speed accuracy and efficiency regardless of formulation, raw material quality, and operator skills. The ECS controls the density of the extrudates externally from the extruder.


The Flextex system controls the starch cooking in the extrusion process. The required product density is maintained by means of on-line control of the specific mechanical energy.
