‘The above proposed mechanisms are useful to study the structural integrity of pellets.
Which of the different above mentioned effects is the most causative factor for pellet
integrity, depends on the combination of raw materials used and the different
operating/processing variables during pelleting, cooling and storage. All these variables
affect pellet integrity, the magnitude of the different binding mechanisms being dependent
on the type of feed produced with its constituents and physical properties.
For quality control reasons, pellet quality devices have been developed to measure
pellet integrity and, again, these devices can be further used to examine the effects of
diet formulation and of process operation conditions on quality of pelleted animal feeds.
