Sweetleaf V2 closed loop system

[A6 Grower]

Sorry, guess i misunderstood. Now that i re read i think i see what your saying...

I was just saying that the high tasting and runny oil has more flavor the shattery low flavor oil you mention probably because of the higher terp %. This was what i noticed with the oil ive had tested, hard shatter had low terp %s and the softer sap had higher terp %'s I usually dont de-wax with a buchner as i run with dry ice and no heat to avoid picking up most waxes.

I'm just transitioning into closed loop extraction so I have had a lot of time in the current paradigm of knowledge to alter my extractions while still fully dissolved. The only benefit of open extraction. If you keep everything cold enough who's to say you can't crack the collection pot early enough, bucher filter the product, put back in the collection and recover the solvent?

What you have explained is a great way to introduce oxygen into your butane supply. That is a disaster waiting to happen.

You can bro, and some do, reporting marvelous results, but from a safety standpoint, we prefer to keep the system closed and the butane away from oxygen at all times.

Besides the safety standpoint, clearly cost per gram is lower if you recover more of your butane at a reasonable cost. We can recover to -26" with our pumps and see no reason to open the system in order to de-wax in situ.

If you don't like the self refrigerating aspect of the Mk VII, you can always chill an upper chamber or heat exchanger with dry ice or liquid nitrogen, vis a vis running the diaphragm pump and evaporating butane to produce the required subzero temperatures.

Not to forget or belabor the point noted by A6, that it is easy to not pick up most of the wax in the first place by extracting with -50C butane. Not only does it make a big difference, it minimizes how much, if any requires subsequent removal.

It does slow down extraction, but with a recycling system, that isn't much of an issue.

.... Obviously you haven't dewaxed very much, the lipid that CAUSES oil to shatter can be precipitated out of the solution very easily through excess low temperature, then separated with a buchner inadvertantly, leaving you with sap

Which is the process and affect I am referring to

Which one?

Also, the obvious question is what molar concentration does this have be to have that effect? And relative to what element?

im confused on where sweatleaf is located now. it seems canna farms moved to CO. are there still reps in cali or was there a fall out between the owners?

 

[Sextracts]

There somewhere in Cali, I just ran into them at the Norcal secret cup and I was very impressed. I was with the guys from Bhogart when I went to there booth, and even they though the welds were very nice. All electro polished real nice looking systems, the only problem being that the system is being used to dewax so its tied for most of the day on one run, and you would need multiple large systems to do anything of any scale, and the price point just isn't right.

 

[analogcricket]

im confused. i heard canna farms moved to CO with sweat leaf.

also, why does it take all day for one run to dewax?

 

[Sextracts]

they did, but the company has reps here in cali, and because it takes at least 2-4 hours for your fats and lipids to fall out of solution fully and have heard of some people dewaxing all night and recovering in the morning for the most effectiveness, although seems overkill to me.

If your butane is chilled to around -70, it does not even pick up much fats and lipids, according to GW....

 

[Pure777Extracts]

I tried freezing my butane and column, and Im not sure what happened but on the second flood butane would not flow and gas was leaking out the butane supply valve handle as if the column froze and would not allow butane in? Any help would be appreciated.

 

[analogcricket]

loving the built in inline and really wanna get a sweetleaf but why are some people complaining about the seals failing and claiming that the inline setup is dangerous and only working half the time. i was reading on IG that someone ran for a month and abandoned it completely due to performance reasons.

Mmm Terpppp

Mmm Terpppp

Ahh Sweet Leaf. They have a nice line of products. Good people too. I met them at the Denver cup. Best of luck to SL!!!

This comment sold me on a Terpp MK IVC. I loved my MK III and now with the larger capacity of GW's MK IV and inline DI chamber, I am sold. Beautiful machines, SweetLeaf... But Im afraid they grew too big for their shoes. Im going with the sure thing.

I'm with Regis, why not make a separate "Cryo Chamber" with a reclaim port to draw a vac on the liquid solution, then when it's cold enough from evaporation dump through lab filter in to reclaim? Seems solid, no DI needed.

That was my theory on the Mk VII, and was based on optical thermocouple readings on a wick sitting in pool of butane evaporating in the wind, but in practice on the Mk V's, I don't have enough pumping capacity to drop the temperature far enough without adding additional cooling.

My latest scheme is to use liquid N2 for the purpose, and save the wear and tear on the pumps.

How cold?

What line sizes?

Any water in your butane?

The secondary dewaxing chamber has been a project I was chasing down but had to put aside since the season is upon us.

Jcoltrane took one of the sleeved spools I had made and ran with it. While the initial trial n ERROR was tedious and frustrating we've acknowledged the major problems have been identified.


The biggest problems were.....
One, the weight of the spool and trying t man handle it. I originally designed it, to soak in the dry ice sleeve, then flip and filter/drain in to a vac'd 12" spool, which we would then recover the solvent from.
Secondly the filters apparently got clogged and stopped the entire process.

Jcoltrane threw some extra ports on it, a few legs and let her run free. Here are some pics



My next step is to take GW's advice and implement sock filters, that can grade the filtration. It would be nice to have this mounted on a frame but my concerns were the waxes coagulating and freezing the the bottom filters ball valves ect. Hence the flipping and dumping idea.
GW this is what I was talking about on friday......

Hopefully some brothers here can provide some input or ideas to get this thing operational, I've got a few lying around.....

Yes, this project was frustracting as hell ... but I will provail!!! I want to say thanks to Perm for letting me roll w/ the idea. It is so nice to work with extractors that help eachother work through idea's and theroy's. I learned more from hitting brick walls while surrounded by supportive people, than anything else.

I agree, the sock fliter is key ... more space between each grade of filter would be good too, and maybe more surface area of filter.

Once again, THANK YOU PERM!!! You kick ass

 

[Chonkski]

Ohhhhhhh my!


This is just about exactly what I was building!!!!! Thank you guys so much for sharing, along with mentioning the trials! I will always return info! Although, I haven't had the chance to even order the rest of the parts.

I had to put it aside for the same reason......... tis the season.

I can't explain my awestruck right now, it's almost envy because I wish I was there to see the test run so bad!

Any water in your butane?

3/8, Must of been water, What is the most common way moisture gets in the system?

Great work! That basically what I was trying to build that as well, I took my old mkiii lid and cut off the dump port so I could just fill it in the 6x12 and set aside in dry ice over night the flip on to my 12x12 for filtering and recovery. I was going for something like the bhogart polisher for filter design. It looks like the use a 1.5" to 3" and then there 3" filter stack. What size filters did you use?

Hee, hee, hee, good experiment! As PC and I discussed, a low micron sock filter will remove the bulk of the precipitated wax and give more surface area, to reduce blinding.

I'm currently looking at a sock filter, followed by a sock filter full of 5 micron glass beads for inline filtration.
