I'm very suprised by this - I usually find just a few minutes on the bench
under an anglepoise lamp is sufficient to dry my pellets.  Its especially
fast if you remove the ethanol, give a v. quick respin and suck off the
last little bit.

I'd be cagey of blowing 'house air' over my pellets - there's no telling
what kind of gunge is in the pipes :-).  I did used to suck air over
pellets (without actually touching the pellet) using a vacuum aspirator to
dry them more quickly - maybe that would work for you?
