I don't consider organic grape seed alcohol the same as other solvents. Resting on a technicality I know, but it wouldn't damage the rosin and still remains in the "organic" spectrum if the product were to be judged by current food and drug standards. I get it though, folks like the one step organic oil process and anything additional becomes suspect.
I use Everclear for lots of extractions. I understand that it's not like other solvents because it's Food Grade. I'm not sure if it would be considered Rosin after the refining process, though. I've read that flavor is lost once you try to refine it further with alcohol. I used a 120u bag to press the above, so I know that I could go down further than that. Normally with hash, plant material is stuck at the 160 level if anywhere. It's gotta be a lot smaller for Rosin, because my recent presses with 90u still had something, but not as much.
Interested to see what you come up with. I can see where you'd lose quite a bit of terpenes in the wash/evap process. That's a definite drawback.
Picked up some goodies the other day! They'll be coming along soon enough! Dr Who Cut: Dark Heart Cheese: Dark Heart Afgooey: Grapestomper:
Been browsing. Can you give a guy a lead on which plate heaters to try? Looking at a few and some seem pretty sketchy. The more DIY the better. I already have some old 6x6 aluminum bar stock so just looking for a heater/thermocouple kit.
http://www.cencalrosin.com/~shop/dual-enail-controller/386493/ This can be used for plates or enails. Mine came with 3x5 dual controlled plates, but you could find thermocouples for it. This is just the base for $144.49. This is where I got my plates for much cheaper than elsewhere, though.
Ok....been doing my homework and putting together the buy list for parts. Then I find reports of test labs finding heat + pressure + terpines are stripping the non-stick surface from parchment and leaving the residue in the rosin. You hear anything about this Disco?
I haven't heard much about it other than the youtube video I saw. I'll have to look into it more. I'd imagine non-silcone based parchment paper would be what we would want to start using. PFTE is what I just found in a search for alternatives, and that's used in medical devices that get implanted.
Is parchment paper all made the same way? According to wiki they just soak paper pulp in sulfuric acid or zinc chloride which causes the pulp to gel. The dried gel is the non stick surface. I wonder what chemicals if any remain to get passed to resin during the hot press?
Bingo! As long as the coating made it so none of the oils were remaining on the plates, I've been thinking the collection res is the way to go!
There are some papers that don't have the silicon coating, but I've read that a lot of them do. As far as Teflon goes, it's supposed to be inert, and can be heated up to 500F before it has issues. Rosin temps are anywhere from 120-220F, so it wouldn't be heated super high.
The problem with teflon is that over time, it comes off. Adding fire to teflon is a big no-no. It makes phosgene.
