Pelleting is the process of converting finely ground mash feed into dense, free flowing pellets or capsules. In this in-depth article we look at the art and science of pelleting. Learn how the industry started, how pellets are made, and what ingredients and aids you need to produce high quality pellets.

Next to protein, starch is one of the primary ingredients used in animal feed. However, starches from different sources offer a range of functional properties that need to be considered. Not only from a nutritional perspective but also from a technological aspect.

Fines segregation can be particularly bad when liquids such as fat and enzymes are applied post-pelleting because a higher percentage will be absorbed by the fines. Also, minerals tend to bind poorly to feed and may make up a greater proportion of the fines.

 Modern birds grow faster when pellet quality is good. They spend less time eating and more time resting. Quality pellets also prevent segregation and allow the birds to get the nutritional package that is designed for them.

Borregaard recommends the New Holmen Pellet Tester, as it provides a more rigorous test and accurately predicts the degradation that pellets experience during transport and handling.

It is well known that various raw materials have a different effect both on pellet quality and throughput. Therefore, changes in formulations might dictate adjustments in operating conditions, like steam pressure, meal temperature, energy input, inclusion of pellet binders etc. It is well known that various raw materials have a different effect both on pellet quality and throughput.
