Making a binary solvent with heptane/naptha and limo wont work to freeze precipitate. Dmt is far too soluble in limo for that to work, even if you used a high amount of naptha/heptane relative to the limo.
If you want to speed the process up and not evap the limo, salt it out with an acidic water and evap it for full spectrum (jimjam) impure salts. What acid you use is irrelevant, and store bought distilled vinegar works very well. Then freebase those salts with lime or sodium carbonate by making a paste with a bit of water, let it dry and pull with warm heptane/naptha & freeze X. Then you get to re-use the limo, get clean solid xtyals, and don't have to wait ages for the limo to evap and get very impure orange smelling freebase oil. You can recover the non-naptha/heptane soluble alkaloids with a bit or dry acetone or iso (if you can get some) after pulling several times with naptha/heptane. So you get white/off white crystals, and the jimjam oil separately.
Evaporating limo to get freebase imho, is the worst possible way to go about it. It will take forever to evap, and limo most of the time does not evap cleanly like naptha/heptane would. It will smell/taste like oranges, and have gunk from the limo in it. Far easier to salt out, base it ala a mini drytek and re-x. This is my preferred method to get xtyals as it uses a fraction of the naptha required if you were using it (naptha) as your np to pull from the basified mhrb solution.
For future extractions consider this method, as it allows you to reuse the same limo several times over, and theres no solvent evaporating meaning no fumes and no unnecessary waste.

In a society in which nearly everybody is dominated by somebody else's mind or by a disembodied mind, it becomes increasingly difficult to learn the truth about the activities of governments and corporations, about the quality or value of products, or about the health of one's own place and economy.
In such a society, also, our private economies will depend less upon the private ownership of real, usable property, and more upon property that is institutional and abstract, beyond individual control, such as money, insurance policies, certificates of deposit, stocks, etc. And as our private economies become more abstract, the mutual, free helps and pleasures of family and community life will be supplanted by a kind of displaced citizenship and by commerce with impersonal and self-interested suppliers...
The great enemy of freedom is the alignment of political power with wealth. This alignment destroys the commonwealth - that is, the natural wealth of localities and the local economies of household, neighborhood, and community - and so destroys democracy, of which the commonwealth is the foundation and practical means.” - Wendell Berry
