How to properly use a diamond miner / pressure vessel

Swagelok. I’d reach out to Corlee valve Co

You can get a 30psi prv made from these dudes.

So if you were using distilled whip it would you go with 60psi?

I got a lid coming in cause I’m making a miner cause I don’t wanna risk jars at all and I’m too scared and I’ve fucked up too many times in jars and now I’m like fuck it all I’m making the miner.

So I have made multiple attempts making diamonds using a diamond miner and have had lots of success and alot of fails. From my experience, the more surface area you have to grow diamonds, the better. Our ETS trainer agreed when we asked him months ago and said that surface area was key which is why we started turning our larger miners on its side and rotate it after we get good growth in the first place but wanted to get some other people’s opinions on this. I have also learned putting to big of a run in the miner can effect it negatively - we would usually get facets on the top layer but everything underneath would be smaller grain-like sugar. Having the material just the right amount of thickness makes it better/easier to get nice facets without the grain-like sugar underneath. I would definitely like to know how folks are using miners upright the size of a collection pot and even material columns (the only ones we leave upright are the small bvv ones) and are filling them up with loads of material getting nice facets without the grain like sugar under the top layer. Ive also tried burping to break the diamonds loose but have never had success. They always stay stuck to the sides of the miner. I’ll post some pics of one of the current runs we are mining with some info from the dry erase board to go along. I’ve also learned some strains definitely like to diamond up better then others but idk how big of a role that plays in making chunky stones. Very impressed with this current run of Acid OG though. Seeding definitely helps kickstart the process after burping for a few days. Thanks in advance for all feedback :call_me_hand:

Increasing the surface area may increase the rate of growth, but it also will lead to more nucleation points. More nucleation points will lead to an increased number of small crystals - instead of fewer diamonds of greater size. For this reason, I would advise against starting the growth process with the miner on its side if your goal is big diamonds (or at least don’t leave it on its side very long). I also see that you have water lines for your miner’s jackets… what temperature do you have the heater(s) set to? Sometimes decreasing your temp and slowing down growth a little bit can help with increasing the size of your diamonds.

On another note, burping to break your diamonds loose is much less effective if your diamonds don’t initially form over the crude (trapping the higher level of solvent beneath the crystals). So, starting the miner on its side may also be working against you for your burping strategy to break the diamonds loose

The circulation bath is set to 32c. To get an accurate temp inside miner I would hook multiple miners up and take the sight glass off and use a temp gun to see the actual temp inside miner and they all were approximately 5 degrees below set temp which is why I set it a little warm.
We aren’t trying to get huge stones honestly (right now). We just want actual chunky looking legit diamonds. Which seems to be a hit or miss which mind you we have only tried maybe 15ish strains out 80-100 strains we have in the building, and from what ive gathered each strains acts/crystalizes differently.
I’ve tried burping the small bvv miner we have to “break loose” but still had no luck. We usually use 70bho/30pho for our solvent and seed and charge with compressed nitrogen.

Are you waiting for a complete puck of THCa crystals to form before attempting the burping to break the diamonds loose? Ideally you want your THCa crystals to form a seal over your crude oil, so that when you burp the miner the pressure differential causes that layer of crystal to break so the solvent beneath it can escape

And yes, you are correct. All strains have a unique ratio of cannabinoids & terpenes and therefore will crystallize differently. One answer to more consistent and reliable crystal formation is isolation and recrystallization

Usually once i see a puck all the sauce is sitting on top of the crystals not vice versa.
We actually are going to try the recrystalization using pentane in one of the small miners Monday. Figured it would be safer starting out vs a mason jar. Been reading on it and the pentane just came. I assume it would be best to start on a Monday so I have the rest of the week to gradually drop the temp. I live an hr from the facility and off on the weekends.

You’re more likely to get a puck that seals over top of the sauce if you start with the miner facing right-side-up. And nice, best of luck. The safest place to handle pentane is in your C1D1 booth, but if removing it from the booth a sealed miner is definitely your safest option. If you need some assistance shoot me a pm… I have all of the answers you seek when it comes to recrystallization - in SOP form

I’ve never seen thca form a puck above the mother liquor. Even if I’m using a diamond miner.

Happens for me more often in jars than in miners. And usually not completely above the mother liquor but rather submerged in the mother liquor with some of the mother liquor trapped beneath the puck

That’s a solid write up. I would make some adjustments to parameters and include more information about safety precautions when working with pentane. But that’s a good start for someone not having done recrystallization with pentane previously

It came from here, a link to it!
I think hexane is a neurotoxin, is pentane?

No I do not believe pentane is considered to be a neurotoxin. But if you’re doing this process correctly your diamonds should have 0ppm pentane after your final purge anyway

I was just referring to transdermal shut, but that’s great to know
I know trying to filter it under vacuum can cause it to boil , what else is dangerous about it…
In addition to the fact that you shouldn’t be using your torch when offgassing pentane, and intentional misuse by deliberately concentrating and inhaling can be harmful or fatal

Pentane’s LEL is even lower than propane or butane. It’s very flammable. But because it has a higher boiling point and is liquid at room temp people often handle it with less care than they would their butane or propane

Oh yeah that makes more sense. I was thinking that you were meaning a puck was forming above the HT. Gotcha, carry on haha

It’s flash point is pretty low, too. At 57°f it can make things go boom, very easily. I’ll only play with open pentane in the booth.
