Copper Scrubbers

Postby CaymanRumBaron » Wed Apr 21, 2010 9:24 am

Hi all,

Ive seen on here that many people use copper pot scrubbers as a packing for thier reflux stills.

How do you guys pack it with the scrubbers? Do you just wedge the scrubber into the column or do you unravel the scrubber and roll it up and then put it into the column? Also do you guys preclean before the first use or clean the scrubbers after use?

I have a 2" X 40" SS column with a screen on the bottom, how many scrubbers would you guys recommend? I think they are a standard size everywhere, like 2.5" X 1".

I tried putting 3 (bottom, middle and top) into my column as they come out of the package (no unraveling, unrolling or anything) and my column would not heat up at all, atleast not at the top where the themometer is. I think it was packed too tight.

Nowhere here sells any rolls of copper mesh that I see on this site as a alternative to the pot scrubbers so that is out.

Thanks Mud but as I said, I cant get that stuff any where around here. All thats around here is pot scrubbers and marbles. That the cons of living on a island in the caribbean.

If the scrubbers are pure copper, they should work fine, just find a way to unfold them and re-roll into a circle like shown from Brewhaus, stuff your column up to the reflux section and try to breathe through it. If you get plenty of air, the vapors should have no problem making the trip. MM

Thanks for the info Mud,

I have about 8 of um so I think that should be enough to do a test run and I definitely try the breath test before I put the column on the boiler.

Thanks again

CaymanRumBaron, you need to pack the entire lower column, from the boiler to the top of the column, with only a small open space below the condenser head...

I slip mine into place using an arrow shaft and never let them pack too tightly... Properly seated and tensioned there will be more friction between the scrubber and the column wall than between the scrubber and the arrow shaft, allowing easy shaft removal...

thats funny Rad, I use an old arrow shaft to shove 'em down there too.

I use 6 of the copper ones in the 24" tower, evenly spaced, so I recon there's about an inch or so between each one . Works like a charm.

Amphora could probably send you mesh if you want it.

I've used stainless steel scrubbers for years. No problems.

Rad and NcHooch,

Do you guys pack them in the form they come from the shop or do you unroll them and reroll them?

I unrolled one and they unroll like a condom (pretty sure we all know how one looks) with a little knot on top. All together about 10" long and 3" wide.

I am just gonna unroll and reroll them into 3" versions of the proper mesh ones. So 9 or 10 of them @ 3" long with 1" spacing should do the job for a 40" column. Might leave out the last one to give a little space between the inlet to the liebig condensor and the last scrubber.

I just stuff em in right out of the box, like I said though, I try to keep em equally spaced through the column.

Unrolled they are actually the same thing as that copper mesh just roll them into a loose cylinder.

You can almost certainly find bulk copper mesh on your island, it's also called copper gauze.
People use it in resin fabrication like carbon fiber and fiberglass, and it's primary purpose is as a stuffing material for pest control... its used to fill rat holes.
Go see the exterminator.

I saw some shiny new copper pot scrubbers in the Dollar Store. At $1.00 for 3 they looked too good to be true….Until I checked them with a magnet. And, of course, they were too good to be true. Made in China – I should have known better. I’ll stick with Brewhaus or Mile Hi in future.

Penny wise – pound foolish (my Grannie would have said).

Hi guys, I think I understand the benefits of stuffing the column with to increase the proof of your runs, but from what I understand using copper also removes sulfides as the vapor rises through the column. Can you still achieve the sulfide removal if you basically soak your finished product in a container with the copper mesh after the run? Sorry if the question sounds silly, but I'm trying to figure out if the benefit of copper only exists with vapor, or is if will provide the same sulfide extraction after the run. Any help is appreciated.

The sulfur compounds are most readily removed when in vapor form... You can experiment and post your findings but I doubt that removal would be effective by adding copper to cooled liquid spirits...

Would something like this be a better approach?

Not without knowing the complete MSDS for that product... Considering how you would be ingesting the final product you need to be 100% certain that you won't be poisoning yourself... Never roll the dice without knowing the odds are in your favor unless you are willing to accept the potential risks and live, or die, with them...

I understand. I looked over the documentation on the product here, http://www.morebeer.com/images/file.php?file_id=4692, before asking. It looks like it is currently used in the wine making process to remove sulfides so I wasn't sure if it would translate for us as well.
I think I'll give the copper mesh a try first. Thanks for the input and help.

The issue that I would have is the difference in the %ABV between wine and distilled spirits... We know that copper in the vapor path is effective and doesn't require additional steps... With wine its use is pretty much the only viable option for salvaging tainted product...

You could always contact the manufacturer if you'd like a more definitive answer regarding its use with high proof spirits... :idea:
