just wanted to clear up some gaps in my understanding on how to make crude. This is my planned process as follows.
Use Bucket Tek Dry Ice + EtOH extraction (the one posted by dustin) to first separate the cannabinoids and terpenes from the trim/flower
Next, I’ll do a carbon scrub with CBleach as, again, outlined by Dustin in another post.
After finishing the carbon scrub and filtering through silica over a filter funnel, have I completed basically all of the steps required to make crude that is ready to be given to a toll processor to convert to distillate?
Yeah, you have the main outline, with the exception of evaporating the alchol. Then there is the task of drying it, and maintaining/storeing it.You will proably need a centifuge as well for recovering your etoh from the biomass.
Hi thanks for the response.
So basically at the end of the process I should be evaporating and recovering the solvent with a centifuge?
And by drying and maintain/storing are you talking about the crude? How exactly should I go about doing these things?
after inital maceration with your extraction solvent you will need to seporate the plant matter from the tincture. Large centifuge style “salad spinners” are used to spin dry the biomass. From there the “tincure” will need to be filtered and then evaporated. This will seporate the resin from the solvent. If your extraction solvent has picked up h20 you will need to dehydrate it.
Ahh okay makes sense. I’m looking at salad spinners and I think I’ll get the Panda spinner. Do you know if any modifications are required to make a panda spinner ready for spinning salad right out of the box?
U dont need anything else for the panda besides a funnel to catch the draining ethanol from the bottom. I would stitch together a mesh bag to throw your “salad” into so that its easy to get everything out of the panda when its done with the cycle.
looks good, you coud skip the c-bleach step. I dont know any crude processors that bleach their product. You might save some $ and fit in with the crowd! Let the distillation lab do the heavy lifting! you would be essentally providing dewaxed bleached crude, when other are providing crude that isn’t. This is especially true for bho crude labs. Make your price reflect your effort, don’t cut your throat to undersell the competition
I dunno about you guys but when I let my dry ice sublimate there is always some nasty hairs and dirt and stuff left behind. If you know when you are going to wash I have had really good luck just keeping the trim and ethanol in the chest freezer for 3 or 4 days. I winterized with dry ice after that and the #1 whatman filter caught nothing (looked almost brand new). I did run it through syringe filters (quite painfully) which did catch stuff and made the extract cleaner looking. Honestly if you have a lab that is going to process you might increase the yield extracting at like -10 or -20 vs -80 but I’m pretty new so just speculation.
Before you make that leap I’d advise you to get 2 sets of normal bubble bags (5 gal), get the 8 count. Then use the 73 and 90 micron bags and fill each with 1.5-2 lbs of milled trim. When pulling the bag out make sure to spin the top and get as much etho back into the pot before going into the panda. Keep the bags spun and the 2 two bags fit on each other. Run the bags for a minute in the panda, then stop it. The other 2 bags are filled and put in the pot. Pour back from the panda and restart it. Set timer for new bags, 10 min. This gives you 4 bags to work with, so while 2 are spinning you soak the other 2. This leads to continuous work. I use machine trim and put 9-12lbs through a 5 gal and lose very little etho.
Edit: i do this at -20c and keep my trim frozen from harvest. Same with the etho.
Oh yeah dry ice is really dirty stuff, i personally never mix the two. I usually put the material and alcochol in the freezer for 2 days then while im extracting i put the material and alcohol in a dry ice chest for 20 min before extracting in a dry ice/iso slurry sleeved column.
Just from seeing what gets left in my covered cold traps from repleneshing alot of dry ice, i definitly didnt want to get all that narly shit in my extract
Well, a carbon scrub filtered through celite 545 was what I meant. I should have been more specific. I personally never get chlorophyll out with just celite, but some carbon thrown into solution before filtering has worked great. Are you able to remove chlorophyll from your tincture with just celite?
