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 ...

When we are pelleting the ingredients with steam, the digestibility of dry matter is improving and lowering the aflatoxin level.So visible the good quality results.

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 ...

The presentation of Jürgen is very valuable for those who have pelleting systems in their feed mills. In addition that he is talking about interesting technical issues, he talks about issues that we often take as a fact and do not bother to go into details. The way the presentation was made, allowed a lot of interaction between the participants, even sharing experiences from their plants. Some of ...

Denis; Extrude Fish Feed is one of the most difficult application for an extruder/expander due to the nature of the ingredients and also due to the configuration of the worms on the main shaft and the restriction applied on the extruder's discharge at the die plate. Most of my experience extruding Feed or Cereals have been made using single screw units. Seems like you are having trouble getting ...
