Tamisium extractor

Hey guys, I was wondering if anybody out there has experience using a Tamisium extractor. Picked up the half pound model from a friend of a friend for a good price. I've used it a few times and keep getting very dark extraction. The tane and material has always been frozen as well as the extractor itself, around -7f. I purge in vac oven for 72 hours at 90f under full vac. Extract is stable to touch and snaps at Room temperature, just can't get that honey color. The beginning material is not dark although it is very dry. The tane tank empties in about 5 minutes so i dont think its a situation where the tane is in contact with material too long. Ive been using approx 3 pnds of tane to .5 pnds of material, could this be the problem. Any suggestions would be greatly appreciated. Thanks.

I have one of those and never had anything but golden honey. You seem to be doing everything right from your explanation. Mine really worked pretty flawlessly. I wish i could be of more help. The only thing I didn't do is freeze anything first. But that shouldn't matter imo.
Try another strain....that may make the difference. I used ice water and hot water for the reclaim part.

I've had one since 2008 and love it, always golden honey here too, and I dont freeze anything but the recovery tank when its time.
Tami for the win!

Thanks guys. I'm thinking it was a loading ratio prob. The Tami website says 4 to 1. I had 150 grams and was pushing thru 1200+ of tane. I'll try again 2moro and update. Is there a Tami forum somewhere out there anyone knows of? Thanks again.

No I don't know of forum. but maybe you found one by the time I responded here. I actually gave up using my Tami as it as just too slow for the small amount it made. Sitting in a box now. I actually have 2 of them collecting dust.

Well, 2 more runs and still dark. I did 1 with fresh picked that I froze for 2 days. All runs have been done at sub zero terms. The fresh stuff I left as whole nugs trying to mitigate chlorophyll. I feel like there is a contaminate somewhere. I scaled my loading ratio down to 4/1. Using new butane, r600, from ecogreen. I notice its golden in the tami but as soon as i pull a vaccum it gets dark. I use a Bogart 1.9 Vac oven and pull it down to 29/30ish at 90f. I just can't see what the vac oven would be doing to make it dark. Am I pulling vacuum to quickly, Should I let it dry for a while before I pull a vacuum. I have friends with closed loops that are running the same material that have no problem with color. I think I'll try a Buchner funnel. Can I run it through the Bucher funell while still in suspension in butane or do I need to purge then dilute in ethynol? Would 99.9 iso work, as I have some lying around. I should also mention that 1 slab I pull a vacuum and with no heat and the results were the same.

Ya you wold maybe have to conclude that the tane is contaminated...good your using fresh. I've never had a Buckner funnel but it would need to a closed system wouldn't it? You could try to winterize it i supposed. I'm not the most knowledgeable guy on this subject. I'm sure the more expert guys will chime in with some help info.
I do believe shatter gets darker at times depending on the strain I've heard.
Does this happen on every strain? Maybe the new butane will solve this.
What i do know is my tasi always made golden oil.

I thought you only extracted from dry material, am i wrong?

I've only used dry material yes.

To me it would stand to reason that the water in fresh wet weed would carry the chlorophyll down into the extract making it darker because chlorophyll is soluble in water...

Yeah, idk. Freezing should trap water. Fresh or dried same color. I'm wondering if I'm recovering to fast. It's passive so I'll I'll put Tami into warm water causing butane to boil and creating pressure diff between Tami and recovery tank. I'll pull a vaccum on Tami next time and see if that helps.

Non polar Butane isn't prone to extracting polar C-55 chlorophyll without water present, but it will extract the olive brown non polar C-55 pheophytin that chlorophyll turns into once it dries and deprotonates.

Best to have some water present and frozen to keep the solvent away from the chlorophyll and the non polar C-40 beta Carotene, as well as the water soluble C-15 anthro cyanin plant pigments.

One secret to bragging quality extracts, is frozen material and -30/50C LPG. With a pumped system, we use a 50/50% blend at that temperature.

Try less heat on the collection pot and lower temperatures on the recovery tank. Try an alcohol dry ice bath. At -50C, you should pull a vacuum.

That's why I spent more effort developing systems with a pump. Even though passive isn't very fast, they sure are slow on finish............

Tami does make a nice system, which I've run along side my own, and found no issues with either. I've also run the ASME BVV system, as well as their Mini passive extractor, with equally good results.

Passive works and is a good way to get into a relatively inexpensive system for personal use.

A subtlety, but chlorophyll is actually insoluble in water, but because the ion in its head makes it hydrophilic, while it has a hydrophobic tail, it will clump into micelles and be transported by the water.

Pheophytin has no ion and is hydrophobic, but can be extracted with non polar solvents.

You can extract from fresh cut if you do it at low enough temperature. We have our prettiest extract with the best aromatics when we extract after about 5 days or so hanging, so that the small twigs snap.

The aromatics are still there, the chlorophyll is still chlorophyll, and there is enough water ice present to tie up the stuff inside the plant cells, including the water soluble anthocyanin plant pigments.

This was a great topic. I've really learned a lot. I've tried extracting before using cheap korean brand and I failed. I didn't get the golden honey extract. Now, I am afraid to extract again. My money was just wasted. After reading this topic, it makes me feel like doing it again but using a great extractor. thanks

@Buzz I'll sell you my TE-700.

@Fade, thanks for the tips. I've learned a lot reading your posts. Much appreciation for those that give time and knowledge.

Try winterizing with everclear to clean darker oil. I'm not very knowledgeable on the subject but there are plenty of videos on how to do it
