There are many factors to discuss on extrusion of fish feeds and as an option chicken feeds. Floating need approx 20 % starch normally and enough shear and pressure in the extruder to achieve expansion. More shear and more pressure equals to greater floatability and pellet strength. Preconditioning prepares the material for the extruder and too much water, which can act like oil which reduces expa ...

Water stability can achieve if you have good particle size from grinding process another hand you still need good binding/ cooking of both conditioner and extrusion. Don’t forget your formulation needs minimum starch around 10% as well.

I would like to add a few more comments regarding making sinking vs floating fish feed. 1. Floating or sinking pellets are dependent on the formulation. Both the type of starch and inclusion rate of starch will make a shaped fish feed float. Generally, sinking pellets incorporate less starch and higher fat, with post-fat application likely. 2. Additionally, the type of die plate used will help wit ...
