Design of fishfeed lines (Farmed and ornamental fish)

Cooking-extrusion to produce fish feed has made many advances.

Thanks to the expansion of the material leaving the die , it is possible to reduce the density of the feed and thus leave space for the addition of fat.

The needs of aquaculturists are different if they are marine fish, freshwater fish, shrimp, age of fish, etc.

The choice of coating (batch, continuous, vacuum or atmospheric) will depend on the target species.

TGC EXTRUSION will be able to advise you to define your production line adapted to your aquaculture and fish food.

For example, the control of density is a key point for defining the behaviour in the water of food (floating, flowing).

Cutting feed out of the system is another critical point. It must be perfect to generate as few fines as possible. This is why we have created a specific granulator knife that ensures perfect alignment between the cutting plane and the die.


Drying is a key step to ensure a good preservation of the product, the choice of the right machine is therefore essential, new energy solutions arrive to limit the financial impact.

The techniques of coating, thanks to the use of vacuum allows a better incorporation of oils. A sequential coating can be made with several ingredients (a main oil in the centre of the pellet and others in the periphery).  But this technique also promotes the addition of micro-ingredients (probiotics, appetites, etc.).

Technical coating solutions limit the oil release effect.

The quality of the flour grinding is another crucial point for obtaining a better gelatinization of the starch, to limit the presence of fines, to ensure the production of micro pellets.
