Sorry I donāt understand that term versus filtration scrub, unless that means mixing 5%wt AC / wt Oleoresin in solution and letting it āsoakā in the solvent/solute?
If yesā¦ then no, i didnāt scrub. Hahahahha!
Maybe your source of ac was the issue try using other adsorbentsā¦I do all my scrubbing really cold and it does look like it helped a lil but not too effectiveā¦maybe other adsorbents will work better than ac
Well hereās an excerpt from the link you posted:
" Important bleaching or adsorption criteria are quantity of activated earth, dosage, time, mixing, temperature, and atmospheric pressure and vacuum [5]. The primary function of the bleaching process is to remove peroxides and secondary oxidation products. In addition pigments and any trace of gums and soaps from refining are removed [5]. The bleaching process is actually performed under steam/nitrogen blanket, vacuum, or in an open vessel. The vacuum provides advantages, like low temperature drying of oils, moisture removal from clay, and avoidance of contact with oxygen of the air [6]. This is because the activated clay may act as a catalyst for oxidation in the presence of oxygen at elevated temperatures. The resulting oxidation products lead to degeneration and short shelf life of the final products. Generally bleaching process is carried out at contact temperature in the range of 80ā120Ā°C and contact time ranging from 20ā40 minutes under vacuum."
I found charcoal didnāt make as much a difference if not heated with media to filter. Summits s.o.p is to mix charcoal to 10:1 solution. Heat and filter over silicate, I wouldnāt excpect just filtering over room temp carbon would do anything for color.
What your saying is counter intuitive to something that is accepted as a fact which is the notion that temperatures play a significant role in the effectiveness of the adsorption process, this is true no matter what adsorbent your using. Which is why when you read about the actual application of bleaching earth on an ndustrial scale such as in edible oil refinement they will typically mix the oil with bleaching earth and heat the mixture while mixing.
Your saying you donāt mix the clay with your butane/bho, you donāt do any kind of stirring or mixing to help the clay particles do their job and you also do your filtration at subzero temps. On top of that your getting more color reduction than people are getting by doing everything they can to increase efficiency of adsorption i.e. heating/stirring a solution of alcohol/bho/clay.
Youāve got to be lying about something.
Whoa whoa whoa, please ditch the negativityā¦ There are a lot of partial statements in the grand scheme of things, and any points of consideration are valued. I understand a novel of āprerecsā, are technically required before any statement, and Iāll definately post results of any process that works well.
I donāt mind wading thru info, and suggestions, and will gladly pay forward any improvement I get.
Letās chill on neg talk and assumption por favor.
Hahahahahahh! ā¦or inquire WHY a cold scrub is getting a blessing from the God of Colorā¦ I think @anon42519203 says dryness is super ultra importantā¦ my AC (CarbChem) was fresh from the bucket sealedā¦ maybe more too itā¦
Next stepā¦
Running a 75C scrub with 5%wt AC to elim AC from the possible solutions, then onto other mediaā¦ will post updated trial here in a few.
Using 1, 2, 3 filter papers from Summitā¦ seem to be fast and great at keeping particles out of the filtered side. A def for the performance. In my short experience, performing exactly as advertised thru their Hock!
