I'm low-tech..
I just spread em out on a coffee filter, write the date and what they are on the filter and stick under my grow lights. (not close, like 6" away)
In about a day or two they are perfectly dry and not fried. Never had any mold yet.
Hell, nature has been drying out seeds for millennia with air-drying.
Then I just fold/roll up the thing into a bindle, secure with a twist-tie or small rubber band and stick into a baggie with a note as to what they are. Seems to work well.
