I recently purchased a Source Turbo to use up all the trim and larf I've been saving in my freezer.
Essentially it's a vacuum chamber with a heated cup, and a slanted glass lid that allows the condensate to drip off separate. A block of ice is placed on the lid to provide a cold surface that collects the vapor.
The vacuum lowers the boiling point of the liquid.
Everclear is available in my area, and I used that as my solvent.
I used a half gallon mason jar filled with dried trim. I allowed this to completely dry, I don't want any water in my solution. Both were kept in the freezer overnight.
The alcohol was poured into the jar, enough to cover, shook, and returned to the freezer for a 5 minutes. I repeated this.
The reason to keep this cold is to minimize the chlorophyll and other undesirables from entering the solution.
I strained it all through a wire strainer, doused it quickly again with fresh alcohol, and strained again. You want to get the plant mass out quickly.
This is where I lost the most alcohol, because some stays in the plant mass and never drains
Afterwards I strained twice through a paper towel. Towels are appx 3 micron, but vary considerably. The resulting liquid was yellow.
I filled the crucible and started it up. It self shut after a 2 hour run, reducing the liquid to about 10% of original. Light brown translucent
I topped it up and ran it again. At this point it became apparent that the provided 6" cake pan was barely enough ice for 1 run. I've since purchased some 6x3 round layer cake pans for additional ice.
This eventually reduced to a thick brown liquid that I spread out on a silicone mat, and stuck in the freezer.
My return has been about 10% using trim and larf. I started with 2 liters of alcohol, and after making 25+ grams of extract, have only 1 liter left. Some spills, some is lost in the filter paper, but most is lost in the soak.
I'm looking at getting a Buchner funnel, and finer filter to see if I can get lighter extract.
