using a dryer

when using an herb dryer, what is the process to assure quality?
tase and appearence wise.

Honostly I don't know the awnser to this one in whole. But I do know that by allowing your buds to dry traditionally (no dryer) the chlorophil dies and is expelled. Excess chlorophil is the cause of that "grassy" taste.. But again I'm no expert when it comes to drying it by machines.
