Khaled Itani, I am referring to the aqua-durability, or the ability of the pellet to stay intact once it's been fed in the water. To go a little more in detail, a desirable fish pellet should be durable enough to remain floating and absorb water, but not change its shape (i.e. disintegrate) after being in the water for a couple of hours. This is important because not all fish will eat right away. ...

If so I had never seen a very extended cooking time inside any extruder. For your reference Extrusion/Cooking time is between 20-30 seconds, also the Extrusion/Cooking temperatures you are mentioning are pretty high and above the standards. I'm afraid that ...

Ingredients segregation is a problem that will directly affect the balancing on the formula and at the same time animal performance in the field. Segregation takes place in the mixer and is caused mainly for excess or lack of mixing time. There are other factors that might be involved like bulk density of the ingredients, non-uniform particle size reduction, addition of liquids, sequence of ingre ...

Many thanks Joe about the topic !!, Joe Kearns is my friend and he has more than 42 years working with Wenger selling Extruders and Dryers for petfood and aquafeed, so he really can manage this Forum in a technical approach. Extrusion cooking systems, I will speak in particuar to single screw extrusion as well twin screw extrusion. Both machines must be fed with a specific formulation regarding ...
