Here is one of next years back logged designs, intended to purge alcohol from shallow dishes, using rapid air exchange, with or without heat.
The attached design doesn't include space for a hot plate, as it is designed around existing filters, but it could be made taller to include one.
I've used fans to rapidly evaporate away Iso and Hexane, and it works well, but can introduce dust in a dusty environment.
It is but from two pieces of plywood, with wooden columns separating the two, and filters on all four sides.
Poly Propylene filters develop an electrostatic charge with air movement, which improves their efficiency, so I like to use them.
