If an air blast is useful for that sort of thing, what can I do to use
the air more efficiently.

No direct experience, just a comment from the peanut gallery. I don't think
this air would need to go through your dryer, just use one of those water
trap/pressure regulators at your mill installed just after a low spot with a
drain valve.
