Zusammenfassung:	A method of treating granules with a coating utilizing an apparatus having a feed chute, a diffuser mounted adjacent the feed chute, a spray nozzle, and an exit chute having a deflector disposed below the diffuser and spray nozzle. The method comprises the steps of: feeding the granules into the feed chute; intersecting the granules with an angled wall of the diffuser to create a curtain of granules falling about a base of the diffuser; spraying the coating from the spray nozzle downwardly away from the diffuser toward the deflector of the exit chute in a predetermined conical pattern; and intersecting the granules with the deflector to redirect the granules into the conical pattern of the coating for treating each of the granules with the coating. The subject invention provides a method of efficiently treating a large throughput of granules with an appropriate amount of coating.
