I have a 5 level food dehydrator that I commandeered for brass drying. If my brass was decapped prior to wet tumbling then I normally set it in the medium setting for 45 minutes. That has always been sufficient to dry the brass, even with all 5 racks filled.
I pre-cleaned a lot of 300 Blackout and 9mm brass in Ultrasonic cleaner. I didn't decap before hand as I prefer to re-size at the same time. I set these cases into the dehydrator for 1 1/2 hours, and despite this, I still had some wetness when I popped the primers. I'm guessing another 30 minutes, 2 hours total, would have take care of it.
Thus, it depends on whether you wet tumbled your cases with or without primers.
My only issue with using a food dehydrator for drying brass is the gaps in the trays is perfectly sized for 380ACP and .223 Rem or 300 Blackout to fall through. I've considered buying a screen window repair kit to line the trays, but it hasn't been a big enough pain (yet) to go through with the expense.
The nice thing about the food dehydrator is after blowing hot air over the brass, 5 or 10 minutes on air only setting cools them right down for immediate handling.
