Ya'll brothers and sisters looking for support extracting or winterizing with ethanol, will be delighted with Extract Craft's recent offering of their Source Turbo, vacuum assisted ethanol recovery system.
It is a counter top vacuum assisted refluxing still, about the size of a blender, that uses vacuum to reduce the temperature necessary to boil away the ethanol, so as to preserve more of the monoterpenes, as well as reduce changes in their properties.
Hee, hee, hee, they sent us a unit to torture and our preliminary testing supports their enthusiasm. Eloquentsolution just happened to have several choices of winterized BHO handy, so we selected about 150 ml from a mixed flower extraction for the trial.
After wiping down the internal surfaces with 190 proof ethanol to remove any contamination, we filtered the winterized solution to be recovered, and poured it into the boiling cup, before setting the lid in place, and placing a pan of ice water on top.
We closed the vacuum valve and started the machine, and started the timer.
Because the machine may be operating at different altitudes, it is necessary to tell it what altitude it is at, by a series of button pushes, explained in detail in accompanying literature. I cleverly misread the destructions, so we ran the device the way it came out of the box, as opposed to optimizing conditions, but it worked anyway.
After marveling at how much watching a pot boil resembles watching grass grow, we retreated to the dabbing and philosophical discussion room and engaged in product testing while the Source Turbo did its thang.
At 1 hr:59 minutes, Eloquentsolution stopped the process, weighted the yield at 9.9 grams, and decanted it for later testing.
More experiments planned, but as for later testing, I'm pleased to report that my own personal anecdotal tests were positive. Still the light sweet taste of ethanol in this batch, and it is about the same consistency as our Clear extract, but as we didn't finish it off in a thin film, that is to be expected.
Two thoughts on the subject. The first is that at that level, ethanol is not insalubrious, and imparts a pleasant sweet taste, so some will choose to consume it in that state.
The second is that it is unwelcome at detectable levels, so added vacuum and heating is required. FDA sets limits for residual ethanol at 5000 ppm or 50 mg per day.
