Introduction Feed pelleting can be defined as conversion of finely ground mash feed into dense, free flowing pellets or capsules, in a process involves steam injection (moisture & heat) and mechanical pressure. There are several advantages for feeding broilers on pelleted rather than mash feed. The main advantage is the improved bird performance (improved feed intake, weight gain and feed...
With regard to cooling, how do you think it effects PDI?
Example, suppose feed is conditioned with steam at 75deg for 30sec pelletted and then cooled to within 6 degrees of ambient. What difference does it make if ambient is 18deg or 28deg?
30 sec conditioning is too low a time
Now a days it is recommended for 120 seconds
for better conditioning and better gelatinisation
to have compact pellet

Inclusion of binding agents (e.g. water (simplest binder), lignin sulphonate, hemicelluloses extract, gelatin, etc.) and/or surfactants can increase pellet quality, pellet throughput, and lower power consumption.

I totally agree with Dr.Farahat. Pellet binder plays a very important role in improving pellet integrity and reducing dust.
