Winterizing after an RSO extraction?

I'm wondering if this process makes sense. Looking for some input.

Start by taking your material and do a conventional RSO extraction using ethanol as the solvent, to be safe.

After the filtration step, instead of distilling the ethanol out, take and put it in the freezer for at least 24 hours. Some additional ethanol may need to be added up to a maximum of 10/1.

Vacuum the frozen slurry with a Büchner funnel to remove the fats, lipids and any remaining plant matter.

Rotovac/distill the solution to remove (most of) the ethanol. Test result by dipping paper clip into solution and lighting with a match. If it sparks, let the solution sit in an open dish to evaporate fully. Repeat frame test.

Final result is then safe for direct injection into vape cartridges and about as pure as one can get.

Comments, suggestions.

RSO is meant for eating.. dont know why you would put it in a vape cartridge with all that extra clorophyll.. THC should be distilled off and purified if any alcohol based extract is to be vaped..

Define RSO. Lots of different versions out besides his original soxhleting in naphtha, including soxhleting in alcohol, but the thing they have in common is their attempts at a full plant extract.

It is absolutely true that it is a poor choice for vaporization due to harshness, and when extracted with alcohol the high chlorophyll even gives some folks severe gastric distress when eaten.

The question was does the process make sense, not the idea.

Some folks are sure that full extract is best for medical reasons, and I'm not here to debate it with them, just help them find out for themselves.
