Just wondering what the best way to make a synth blend is.

Currently I dissolve the chems with acetone, mix that with some damiana and stir until crumbly dry, then lay it out on a baking try for a good few hours.

Was wondering if there's a way of keeping the mixture moving while the acetone evaporates without me having to stir it, takes like 30-60 mins. Maybe a slow rotation blender or mini concrete like thing?
