I don't generally bother with PLA. I store my filament in gallon ziplock bags with desiccant, and that keeps PLA plenty dry for a year or more. Everything else I dry ahead of time.
But not for 12hrs. I have one of these and it will dry anything in 4hrs or less.
Dry it 4-6 hours at 65-70°C.
Food dehydrator that goes to 90°C for nylon. You don't want any bigger. These things heat the room.
