DIY-Tobacco-NET

Hi all

I will use this place to introduce myself.
I am from Croatia, gave up smoking cigarettes 3 months ago, started vaping with commercial e liquids, mostly tobacco, , soon after started diy ejuiceing, bought some aroma, tried some NET recently, it was BlackNote Quartet, I liked it , ordered some NET from La Tabaccheria from Italy, Latakia, Virginia, Perique, Kentucky and Oriental...all very strong but bold somehow....did try some mixes as well.
I have found those concentrates to be to sweet compared to BlackNote which is sweet as well but other, different more likable sweet taste.
Than I have found DIY NET forum posts with some information and then more and more so decided to try myself.
My first attempt came out of freezer yesterday and I am vaping it right now.
It is Partagas Serie D No.4 cigar which was extracted with heated ethanol 12 /freezer 48 hours method.
For filtering I bought 20 years old, not too much used, centrifuge, very dirty but perfectly functioning, 6000rev closed bucket, hinged Megafuge 1 for which I still wait tubes to do first sedimentation.

Now to the point, in my jars, at the moment:
Pipe Tobaccos I managed to get here are:

Savinelli; Black Cavendish
Ashton SmoothSailing
Mac Baren Original Choice and Vanilla Classic
Borkum Riff Bronze

Jars are in Crock pot at the moment...for few more hours.

Looks like you are on your way to making some fine extractions ! Be sure to clean that centrifuge very well. Hot soapy water and lots of it, also some diluted Bleach (Chlorine/Sodium hypochlorite type). Many used centrifuges have been used in medical labs, so cleaning them is mandatory.

Well,, keep us updated with the results of your projects. And, be sure to try a PG only extraction. It takes longer than alcohol extractions, but the flavor profile is much broader.

And, be sure to try a PG only extraction.

I agree with Peter_Ramish there. I tried ethanol extraction method. It works well on certain pipe tobacco blends, especially cased and top coated blends. As for cigars and single leaf varietals, or non-cased tobaccos, PG extracts had a better flavor in my opinion. Although it does take longer.

I am also working on several VG/Ethanol extracts to compare with PG extracts, but I am letting them sit for a year before I filter them and compare them. The first round will be ready in August of this year.

I look forward to seeing how everything works for you.

Hi all
It is nice to have you here to share..

My first centrifuge run was a major disaster.
I loaded 12 tubes and let it run for 70 minutes....first 40min on 4500rev and than 30 on 5500rev.
When I opened the lid I found most of the tubes to be broken, partly deformed from heat.

For next run I will try 4000rev max, less loaded(I loaded them up to the top), it seems that max speed for swinging bucket closed rotor is less than for fix one.

Funny thing, even those few that survived the run, I found no visible deposit at the bottom of the tube?

Will keep you updated

Wow, sounds like a mess. Never tried a centrifuge myself. I think at some point I may give it a try. In the meantime I will be using a glass filter funnel under vacuum. Kind of like this: https://www.ebay.com/itm/500ml-Filtrati ... SwkEFd8zyh

I just haven't decided at what micron level I want to filter or at what temperature. I may split the extracts further and experiment with different filtration methods, see which one results in the cleanest extract without compromising flavor.

Hope your next batch goes better. Peter_Ramish is pretty well versed with centrifuges. I'm sure he'll have insight.

I have never heard of anything like that. Something is mechanically wrong with the machine. It sounds like the rotor is missing parts of the bearing carriage that aligns the swinging buckets, therefor allowing them to crash into each other. Dose this centrifuge, when running, make any unusual noise? A properly running centrifuge should make no noise other than a smooth fan sound. -And the heat you mention? There should be no source or cause of heat that melts the tubes !!! So your result is most unusual to say the least.

Spoke to Megafuge service guy from Zagreb...he thinks that speed and time should be reduced for given PPtubes, than to tray to swap tubes for free standing conical type where there is a protruding ring at the base to reduce the force from conical tip.
Rotor is perfectly balanced, dead silent when unloaded, slight vibration at point in revs when swinging buckets starts to get back down by gravity.
When properly loaded still OK, little to zero vibration....from its sound there was no reason to think anything is out of normal for me.

This type of rotor is closed and has no ventilation, temperature rise is provoked from air resistance to rotor housing while spinning .
Is there a way to attach image direct to post?
If so, I can send few.

Will keep you updated

Hi all

My centrifuge was in quarantined area but now it is free to go.
I made another run, without cover for better cooling, 4500rev for 1/2 hour and as with first attempt there was no deposit(pellet) at the bottom of tube at all.
I am concluding that ethyl alcohol macerated tobacco extract, when filtered(twice) after freezing for 3 days in deep freezer trough coffee filter, does not contain particles whose density is higher than solution which may be sediment-ed with mine centrifuge at this revs.
Even the first run, which was at max 6000revs for more then hour did not produce any pellet.

Now, for PG or VG macerat, which I plan (PG only this time), I think centrifuge sedimentation will show it's strength.

Opinion?

Thanks

Not sure why you would pre filter then centrifuge. I use the centrifuge so that i can avoid mechnical filtration. Also extended macceration techniques will create more debris than the short times I think you are using. I use both extended maceration times, and ultra sonic destruction of cell walls. Both those techniques create a lot of debris that must be later removed.
