Terpenation at Terpene Station

[FatherEarth]

Veg,

what "gas blend " are you going to be running?

 

[FatherEarth]

A crystal update. So I dug up some samples from past extractions and did a microscope exam on each. Surprisingly I found crystal formations in all of them. Crystals in varying stages of development, slow evap'd extracts showing the largest and most formed crystals. Im in the middle of a few experiments right now after they are complete I will post some data and pics.

One other thing worth noting is that the older extracts that had been jarred for a month or so also had mold growth within the oil if it was at all pliable or a bit gooey it was contaminated. Make sure you are fully drying your oils before storage. Luckily my samples arent my stash, I only keep a gram or so of each for later reference just in case problems arise I still have a record of the batch.

Respectfully,


FE

K need help here. Did an open container soak with whole buds the other day with ethanol winterization. Came out amazing.

In comes the problem. Did another one, same method, only this time with 80% buds that were ground up and 20% rerun ground up as well. One other difference is I evaporated my winterization wash in the sun. So I'm now wondering....was it the buds being ground up or me evaporating in the sun that caused my product to come out SUPER dark and very stoney?

I am going to try 70% n-Butane to 30% propane.

 

[FatherEarth]

I would say its ground material making it dark. Sunlight will turn the chlorophyll an amber color. If you want every last morsel from the bud( good and bad) then grind them.

 

[FatherEarth]

Veg,
What are the benefits of this 'blend'?
How much will that 30% effect your PSI? I know when you dont burp your tank after filling with cans the PSI gets kind of ridiculous and seems like it would be overall stress with the sudden bursts of pressure every time you open a valve. Also makes an annoying whistle..lol

GW, did you ever figure out if the MKIII could handle straight propane?

Wouldn't freezing the extracts for long term storage prevent mold growth? I've been freezing bud for years to preserve potency. I've been freezing my batches of oil over the last few weeks, but I haven't seen how oil holds up after a few years in the freezer.

Grinding bud will produce a darker extract, as will using heat.

The Mk IIIA will run straight propane and makes a gorgeous light extract, though the yield was lower and it takes about twice as long to recover.

We just ran experiments with the recovery tank sitting in denatured alcohol and dry ice, which dramatically reduced recovery time for the butane, and plan to re-run the propane experiments using dry ice.

 

[FatherEarth]

Denatured alc and Dry Ice eh? Can you explain what that does? I assume a super cold bath?? Thanks GW

Ran my terp with material in it for the first time, froze up so hard that I had to use hot water to get it to finish. I guess 50* F isn't a good temperature to be terpenating at.

 

[Veg N Out]

If I shut the "IN" port on the appion before shut down, will it evacuate all the butane left in the recovery pump and vapor line?

I haven't figured out how to keep it from spewing the liquid butane in the line going to valve #4 and to the condensate line when I'm shutting it down. It's not a lot, but I'd like to recover as much as possible.

Thanks for any guidance.

FE -

I haven't tried any blended gas yet, only gas from lighter cans

we run our terp with the storage tank in dry ice (-40 to -60) and no heat on the base of the terp. things definitely ice up, but it produces a more pure product with less waxes and what not. it can take upwards of 15-30 sec to fill the column. we then vac till about -12 on the last run and pour off the oil into a pan. you can use a heat gun to warm a spot on the side of the base to remove the frost and then have it blow cool air on the same area to see where the butane truly is in the base. that way you don't waste a bunch of butane. it takes us about 45 min to do 5 cycles and get ready to pour. if we do two columns, the second run can take upwards of an hour.

to clear your line going to valve 4, simply close the know on your storage tank and then leave 4 open when you are purging at the end of your cycles. i normally wait till the column is completely dumped before i introduce new butane from the line. once you get into the negative pressure, you can close 4 and undo that hose while they system is still purging.

 

[mr. durden]

condensate line?

 

[Veg N Out]

condensate line?

The line marked "out" on my appion.

Let the in side pull air from atmosphere and run for about 20 seconds

I pulled 13 grams from a tube full of trim, was fluffy white awesomeness and I applied a little too much heat to it and it got a bit amber. Overall I'm really happy and about to run 2 more tubes.

One thing that's happening is my system isn't running at very high pressure, is this because I'm not heating the recovery pot and only icing down the refrigerant recovery tank?

On the above run , butane began to escape past the top clamp so I shut the appion down, dumped the tube, and continued with the run to a successful finish. Am I packing the tube too tight? I put 2 coffee filters down the bottom then begin filling and pack with a 1 3/8 dowel pushing each load down once as hard as I can.

I remember in class we were running at like 40ish PSI , My system is only getting to 20. The refrigerant recovery tank has 7.25lbs of butane in it and I haven't heated the recovery pot , only have the refrigerant tank in a cooler encased in ice.

Before it vented butane vapor out the top tricamp gasket I was in the middle of the final flood, the pressure rocketed from the 20psi it had been running at to 35ish , the entire recovery pot and column began to ice over and that is when vapors came out, i'm assuming because the total volume of the system couldn't hold the volume of butane plus the oil in the pot?

I am using a JB M2 -250B gauge that I zeroed before the run and pumped down to -10hg as instructed by Skunk Pharm in between cycling valves #2 and #4

Thanks

 

[mr. durden]

yeah, not running heat will result in you not having as high a psi.

the top clamp on the tube? if so, maybe you didn't tighten it enough?

how much material are you getting into your tubes? i average about 175g. i'd say 150 is a good number to shoot for if you are grinding your material. i too use a long wood dowel. i use 2 sets of 3 10-12 cup coffee filters each on the top and bottom. i also inserted a finer mesh screen over the one that came with the system, top and bottom. just in case something gets by the coffee filters. better to be safe than sorry.

i'd also bump up your butane to 10 to 12 gallons. you might as well save yourself some time and leave a little butane in your system versus trying to reclaim all of it.

the column will always ice over on your dump. if you are using a 24" column and waiting to dump when the system is at -10, you should have enough room.

i believe that gauge is class a, which is good.

i don't do that 5 min hard vac anymore... especially when doing a cold extraction.

 

[Veg N Out]

It's because I flooded the system with too much tane from being too high running my machine. I did it right the second time and doubled the yield.

 

[mr. durden]

oh gotchya. so you basically flooded longer than however it took to get the return tube cold?

you should just leave some butane in your system and pour it off... you'll have a more stable product to work with
