Surfactant Addition
Recent studies have indicated that the incorporation of
food-grade surfactants added to the meal can enhance
the overall conditioning of the feed. The surfactant reduces
the surface tension of the water, thus allowing a much
faster permeation of the feed particles during the conditioning
process. Moisture serves as the conduit for heat
transfer into the feed particles, therefore, if the moisture
permeates the feed at a faster rate, heat transfers to the
feed in the pelleting conditioner faster. |
