Have a read of this:
Extracting DMT with ethanol, vinegar and sodium carbonate. It should be possible to substitute the ethanol with acetone.
To speed up the drying of the sodium carbonate paste, use anhydrous sodium carbonate. This is retail available in some locations, and can be made very easily by heating sodium bicarbonate either in the oven at 200°C or in a stainless steel pan until it stops "levitating" and no more water vapour is being given off.
Mixing acetone and vinegar would be of little consequence but that shouldn't happen anyhow if you've neutralised all the vinegar with sodium carbonate.
Freebase DMT is exceedingly soluble in acetone so there's no need to heat. Indeed, heat will just cause the acetone to evaporate - room temperature is fine. Do bear in mind that acetone is somewhat hygroscopic though.
I'd do at least 3 pulls just to be sure. While the acetone dissolves the DMT very well, it's hard to get the solvent residue out of the solid matrix without using suction. Use extra pulls to get most of the remnants and be mindful of the proportion of solvent holdup to guide you in this.
I look forward to hearing exactly how you proceed with this and of course what the results are.
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
