Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature. The moisture, temperature, and time involved combine to impart a sticky surface to starch-containing ingredients which, when subsequently dried, improved pellet hardness and water stability.

In the conditioning process, moisture content is increased before the groats pass through a kiln where they are heated using dry heat radiators to a temperature of approximately 215 degrees F. During the heating process, steam inactivates enzymes present in raw grain, the groats are given a roasted nutty flavor, starch gelatinization occurs, and moisture level is reduced to a point acceptable ...
