How is extruded feed produced?

MIXING & MILLING

Various raw materials are mixed and ground to a fine meal which feeds the extrusion installation.

CONDITIONING

The flour is humidified, injected with steam and kneaded until it becomes viscous.

EXTRUSION ...

The hot dough is mechanically forced through the tiny holes in the die-plate so long strands are formed.

... AND CUTTING

Just after the die rotating knives cut the strands into pellets of the desired dimensions.

DRYING

The pellets are dried using hot air.

COATING

After drying, the granules may optionally be coated with oils and / or other desired fluids.

COOLING

The pellets are cooled by means of ventilation with the aid of ambient air.

CRUMBLING

Optionally, the grain is crumbled to the desired size so as to provide fish larvae of feed with an adjusted grain size.

PACKAGING

Finally, the pellets are stored in silos before being delivered in bulk or bags.

The above steps explain the extrusion process. This schematic representation is, of course, a simplification of the real process.
