I’m using ethanol- is hot reflux with AC and BC still doable without any other steps?
I have AC granular pieces but also have powder avail as well, my BC is all powdered- I use the AC for some workups/cleanups in the ol synthetic playground that is the other side of my lab.
lol ive been reading them, i must of skipped over the filtering butane through a buchner part but i did see the filter stack remediation tek now that you mention it. ive been focused more on lab tek than extraction for the past couple of months. been an extraction tech for over 4yrs, i run a custom built CLS, i know alittle bit lol. it would be hard for me to implement the filter stack remediation tech on my unit. its cool to hear the crazy shit you artists are doing that i would have never thought of though. so much useful info and informative people on here, i really apreciate all the shared knowlege. for real!
Also are there other clays out there that will do the job? There is a boatload here and a wide variety as we were formerly producing face masks and other topical clays.
oh and you cant search t5 in the search bar, its too short.
Seconded! This forum is a wealth of information and great folks helping each other out - kinda hard to find a community like this in any industry, let alone green.
just wrote out a new winterization and filtering protocol this morning but i will give it a look 
Have you been under a rock the past few weeks? Lol check out that crc thread
even more knowledge!!! fuck yes
Oh, yeah, definitely dont filter through a buchner with butane lol. Various chemical properties of butane allow the extract to interact more favorably with the t5, your best bet for filtering it over t5 in a buchner is probably heptane, ethanol works as a carrier for picking up water solubles but not much else.
nah not under a rock, just trying to deal with isomerization problems, color problems, % problems. mostly trying to get our lab on track, as i am the only one doing any active research about fixing our issues instead of walking around with my head up my ass making assumtions like these fools i work with lol
Makes sense… i didnt really like the t5 or ac with celite funneled … and that was when waxplug was only letting out small hints… i tried few different combos before he dropped b80 and celite as his go to…
What is the exact process of swelling the bentonite clay? Anyone have any videos or literature?
Would be cool to be able to buy any old food grade bentonite and prepare the clay at home.
It seems that the most common way to activate the clay is to mix it into an organic acid, allow it it to react for some amount of time (24 hours in this literature), followed by removing and heating the clay to 200C to dry it out. It is then ground to appropriate size. This literature says that various acids can be used, acetic, phosphoric, oxalic, but that oxalic acid creates the most active sites. Doesn’t seem like its too hard to do, as long as you source your starting clay responsibly. here is the article
So I have been offered the following options for bentonite:
-Activated Bentonite
AC Bent Oeno J is a sodium-calcium bentonite,
with extremely low iron content, to be used
especially for the treatment of grape must. It gives
an early and lasting protein stabilization in the must
stage and could be fermented together with the wine
easily.
Main characteristics
• Best protein absorption action from the beginning
• Remains in the must during fermentation.
• Easy and quick dispersion
• Low inert matter content
• Deposit volumes reduced to a minimum
• Extreme low iron and arsenic content
The high quality of the bentonite used ensures
protein stabilization and proper clarification.
The low iron content doesn’t lead to an additional
blue finishing demand.
-Bentonite for ultra filtration
AC BE N T O E NO UF is a sodium-calcium bentonite,
with the following characteristics:
• good deproteinising action
• easy dispersion
• low inert matter content
• deposit volumes reduced to a minimum
• the smell and taste of the wine are
not affected
-Natural Sodium Bentonite
Didn’t get more information on this
It’s from a company that supplies the food and wine industry.
The information doc which I received for 2 of the variants doesn’t mention anything about the PH, so I’m not sure about that.
Does anyone have any idea which one will be most applicable for to use as a adsorbent to remove water solubles?
The end product is crude.
This is the way.
Any acid works, it is just important to control the pH and not going below pH 4 (or not to far for no too long, followed by convenient washing).
But what is difficult in this process is recollecting the clay at the end. At small scale, centriguation works well, but high force are needed to separate well the clay from the solution.
I think I have described the big lines of the process in this thread.
But this is starting with a spent activated bentonite.
If starting from the natural one,one needs to get rid of the accessory minerals as well (bentonites are generally 70-80% clay). There are various methods, including physical and chemical treatments. In addition to saline and acid treatment, reducer and oxidants may also be used to get rid of oxides or organics and carbonates…
At small scale, a “simple” elutriation is, I think, the best method (and very underground in that topic). This is not difficult at all, and not tedious. It is also only physical. Still, I only did small scale (system for 10-20g/week) for month, running parallel systems. I find it much superior that iterative centrifugation or simple sedimentation to get pure clay minerals, efficiently, and with much less work (once set, it kinda works alone in the background). This is something still to be developed at mid-large scale…
It depends also on what is in the starting bentonite. There are different sorts. One should prefer to start from Fe poor and clay rich ones. The Wyoming type (not necessary from Wyoming, the greek ones are similar) seems to be the best candidates.
Howe much T5 should i use for a 1 end 1/2 2 pond rune???
Could you try to say that again?
Is he talking about a volvo on a drag strip ?
1 T5 and 3 bar boost should do a 1/2 2 pond run.
