Leaving ethanol in the filter

Post by samleeds »

In the past I always flushed the water out of the filter and chucked it when the ethanol appeared, then after filtering I would chase the ethanol out by using fresh ro water which stayed in the filter so as not to dry it out. My new filter is pretty big, so could I leave the ethanol in it, so I don't need to prat around with flushing. Ive got plenty of ethanol to work with so leaving a litre or so in the filter wouldn't hurt me, but when it comes round time to filter another batch in a month or so, can I still use the ethanol that has been sitting in the carbon in the filter. If that's ok I can just fill the reservoir and filter and mix, filter and mix and so on.

I always flush with water and throw carbon then use fresh next time

The amount of carbon in my filter will do 60 litres. I meant if I only put through 20 litres, can the ethanol stay there till i get another batch to run which is usually 2 weeks

I don't see why not. If the carbon was going to taint the alcohol
in any way, you wouldn't put it in there in the first place.

On that score, I am agnostic and the angels dont get anything as my filter is airtight and sealed both ends. lol.

I simply run my Essencia half a dozen times or so, and then switch the carbon.
It is a personal choice.

Ed. Absolutely... Why are you flushing with water? This is introducing a problem.

If you have enough neutral to leave your essencia charged, then you will lose a little to the angels.

Interesting... I just got a SS filter, the big stainless one. Takes 500gm of carbon, and so far has made a big difference to the couple of runs I have put through it. I was wondering how much I could filter thru it before changing the carbon, and I also thought of keeping some ethanol in it to stop it drying out. If I flushed it it's just introducing more water into the ethanol, and also me needing to produce more RO water to flush with. So far getting some good clean tasting and clean smelling neutral out of it. Reasonably pleased apart from the price.

I use a freshly charged Z filter and put a max of 50 litres through it (at about the 40% area).

It uses about 300ml of carbon, so then it gets removed and the filter recharged.

The "spent" carbon is the rinsed repeatedly in boiling water (as per Gert Strand's - Carbon filter ebook. When there's no smell of spirit left, it's dried out on a baking tray in a low oven, then once dry it goes back into my carbon stash.

Seems to work well

I'm just catching up on this thread, interesting for me because in my AS days I did use the filter. Then you read more & more about using carbon, some folks say "if you do the job correct, you don't need to filter". I've read Gert's book and to a layman like me it makes sense, I do have a bag of carbon in the cupboard, and I did a run with a small homemade filter just the other month.

I watched George on youtube make a tube filter, and he seems to make a lot of sense about filtering likker. I have a 4" SS section in the garage, heaven only knows how I came by it, I can't remember buying it. The other week while doing a spirit run I came across it, then a bulb went off in the old grey matter....I use a 2"x 4"x 2" torpedo, use one side of the torpedo down to 2", reduce to 15mm, add a tap to control flow and ally hoop one filter tube.

I managed to finish this tube filter, I'll need to fit some sort of bracket and maybe fix it to the wall?? The photo is in 2 shots, job to get it all in without being too far away then there's no detail. The SS section is 12" x 4" tall, then there's about another 12".

Sorry, Moss didn't intend to give you a coronary, it was the way on the old site to save space. I'll upload in the future mate.

Please don’t misunderstand me - the initial shock was soon over.
I just wanted to point out that we are a bit looser about this kind of thing. It is easier to use our server and as long as our members are as generous as they are now, we can continue to make it easier.

Just looked at the images again and they display better when they are included in the post anyway 😎

Leaving the last few posts on one side;
That is one of the prettiest filters I have seen.
Nice one Ice.

Just as an aside, but related topic....

How much spirit (max) would you filter through 500gm of Activated Carbon?
Sort of average / ball park figure would be fine.
Reason is, just sorted a tall filter of about 1.5" dia, and it takes about 500gm of carbon, and don't want to waste it unnecessarily.

If I remember correctly in the above video any tube under 2"dia will not work properly??? the liquid runs down the inside wall of the filter and doesn't work as well. He also tells you how much likker can be treated with a certain amount of carbon.

Well I think my "Z" filter holds about 300gm per charge. I try to aim for 10 ltr batches as that's the reservoir bucket holds. I find I get good results for about 40 litres (and that's running the spirit through twice). I make sure that the spirit is IRO 40% ABV, but I don't worry about being exact, just as long as it's 40% minimum (highest I've run through the filter unit is about 45%).

Equally, once I consider the carbon "spent" I use Gert Strands method to clean it up for reuse (once I get no smell of spirit from it, I dry it out in a low oven temp, then it just goes back into the bag of dry stuff for reuse - means I only get a new bag once a year).......

But as with anything like this YMMV..........
