Greetings to all good folk:
I have joined the R&D brigade and am trying to learn extraction.
I have read thru most of the longer threads so I hope I won't sound like a fool. (ie, question easily answered on post 417 in BHO lovers thread etc etc).
If I do, please be patient with me.
I have a 1 pound BVV extractor, bi directional with water jacket on the honey pot and recovery pot. I have done 14 runs and building my database of material and process data. I have had results all over the map.
I have had runs that came out with a 17% (80g) yield that was golden yellow clear shatter that made peoples mouths drop and stunned that it was not winterized. (Fourth run: To quote Jeremy Clarkson, "How hard can this be.") This from my own trim that I make sure is only sugar trim from second trim, over six months old. Only get runs like this off my own material,
I have had runs that came out 3% (15g) of blackpool (look, not the city) consistency from purchased trim of Fire OG.
I have also ran fresh trim (days old off a machine trimmer) that yielded well (12%, 55 g) but had the blackpool consistency.
PROCESS:
I stick trim in freezer, and keep it there anywhere from 1 day to weeks. Then stack dewax column with material, tamping down with a 2" dowl, not packed completely hard but definitely compressed. Then stick spool into freezer over night or weekend.
I assemble my system and pull it down to -30 with vac pump
I use rice DI to pack the spool and the inlet condenser coil from Solvent tank (n-Butane). Let sit for 20 minutes, to chill down the spool even further.
Inject fluid into bottom of spool and fill chamber. Let solvent sit in spool for 20 minutes. Re-valve to top fill and let discharge flow into chamber pot. When chamber is filled with liquid (about 1/2 inch from bottom of discharge pipe), I shut valve, fill the top spool with liquid again and let that sit for Approx 30 min while the first "blast" is recovered by my TRS-21. TRS-21 has a filter on intake and then goes into another condenser coil which is filled with ice, and changed frequently.
I have a re-purposed Sous vide machine running at a 31 C set point to heat my water. Using a 290 GPH maxi jet I run that water thru the lower portion of the water jacketed honey pot.
When Almost empty, I discharge the 2nd blast and let that run into recovery pot. When I get to -10 psi, I shut down pull honey pot, pour onto parchment paper and stick in Vac oven at -27 and 93 F.
So that is it, for now. I have to run. Any and all help & information is greatly appreciated.
And, of course, would love to hear from that great spirit animal of this forum. Lupus gris.
