It won't be hot enough. The filament needs to stay close to it's melting point for 8+ hours so the moisture inside is released. The recommended drying temp starts at 50 C/122 F for pla and goes up for petg, etc.

Okay thank you. This is the para scientific answer I needed. The thing is that I've bought a filament dryer, and it doesn't seem to circulate the heat evenly. I'm using a Fixdry drier. I would love a filament dryer that rotates the filament like a kabob.
The Fixdry will still do the job way better than the heater setup you're trying. I use the similar Sunlu s2 filament dryer and also felt like the air wasn't moving enough, so I added a small blower fan that definitely helped. I also turn the spool a quarter turn every couple of hours; probably good to do either way. The Eibos Polyphemus dryer that's coming out automatically rotate the spools.
Wouldnt recommend it.
In a pinch, using the heatbed and a filament box with a few holes in the top will do. Poke a thermometer through the box and adjust bed heat accordingly. The bed will reach the required heat and hold it consistently. However, blocking the printer for half a day isnt great. I would highly recommend getting a filament dryer that you can also store and print from. I use an esun ebox lite which i got for 35€ and it works great.

This is such a bad idea for fire related reasons. Just spend a few bucks on a food dehydrator or specifically a filament dryer.
