While DK is sharing the pictures of the process, I actually built the unit. I don't have a running total of what it took to build it. Most of the pieces were made by hand. Some of which was very tedious. The most expensive part would be the recovery pump which I scored for free thanks to a good friend. The unit is VERY stout and weighs an estimated 70LBS.
I think that some people are missing the point on of the price of butane. With a vent to atmosphere extractor, you put your few cans through it and your wad is spent. This setup holds about 3.5 cans in its tank. When I run that through once it's about even with a vent to atmosphere setup. However as I cycle the system I can put that 3.5 cans through the material as many times as I choose. Say I cycle it 3 times then that is the equivalant of blowing 10.5 cans into the atmosphere. What's the point? You may ask... well here we put high grade material, often whole plants minus the fan leaves and stems, into the extractor and are quite determined to get as much return of oil as possible. That is where the vapor recovery system really shines.
Another point worth mentioning is the fact that the recovery system pulls a vacuum on the extractor as it reclaims the butane vapor. That vacuum allows the butane to boil out of the oil easier and requires less of a purge on the finished oil. The vacuum also allows the butane to boil into vapor at a lower temperature and considering how cold the unit gets during the process, that is a plus. I noted that GW is incorporating a heater into his setup, I simply use a heat gun to knock the frost off and assist the last bit of liquid to boil off.
The cycle time starts at about an hour for one cycle. With 2 or 3 cycles it can go over two hours. A lot of the time spent is pulling the vacuum on extractor after the cycle. Cycle times can be shortened considerably if you dont spend as much time pulling the vacuum. The flip side is that there will be a lot more purging necessary and more loss of butane in the oil.
Like I alluded to before, we don't run fan leaves and stems. Our focus is on making the best oils around and the best oils aren't made from the trash. An average QP will fill our extraction tube approximately 80-85% and can yield from 10G to almost 30G depending on the quality of material being extracted.
To answer someone's previous question, butane boils at 31 degrees F at atmospheric pressure.
Thanks for the Pro Tip!!!!
Along with the sculpting tools you recommended in GW's thread detailing how to build an Active Recovery Butane Extraction System, you have given me a few more tools in my scraping arsenal...
Where's the new thread for this if there is one? Also are there any other threads you used to help you make this? I can't afford buying kits as I'm broke but I think I could slowly put something together. I have a few pounds worth of plant that I just can't deal with trimming from arthritis and this would store nicely in a freezer.
Any one at all that has some related links on building these sorts of things or the obvious higher quality one in this thread please respond. I desperately need to deal with some hang dried plants.
