Adding a 2nd Thumper

Postby Biker Mark » Wed May 03, 2017 4:28 am

I'm adding a 2nd Thump Keg to my rig, and was wondering about the cleaning process.
With a new still I know to do a vingear run, then a water run, then a sacrificial alcohol run, but is this ALL needed for just a thumper?
I don't want to lose my seasoning on my entire still, but I know I have to get the new piece cleaned properly.
Any way to clean just a thumper?

With the newly added thumper, did you add any new piping? Are there solder joints which have not yet been cleaned through a sac run?

A good cleaning protocol won't adversely affect your boiler, primary thumper, piping, etc. Sometimes it is simply better "safe than sorry" to run a new protocol. Otherwise, it's a "crap shoot"....in more ways than one!

That's what I figured.
I'll just have to get a couple ferments going and run the cleaning process while they're working off.

Thanks.

If you build it with unions and small enough sections you could manually clean the Flux and stuff out.

I'm about to add another full size keg as my thumper and have a 7.75 gal keg just sitting there sooo... here comes another build for a double thumper.

Wash/mash/must in main boiler, muck and stuff in 1st thumper and low wines in the small 2nd thumper.
Damn I have alot of work to do.

I'll use all 1" unions for all the connections to keep it modular to fit any needs that arise.

Good luck BM and post pics.

I like to use bottle brushes from local home brew store. i cut the loop off the end, chuck it into a drill, insert it into the new copper/solder joint with some dish soap and scrub the hell out of it. Rinse with hot water.

It's the vinegar in my boiler that I was trying to avoid.
What if I fill the boiler with water, and put vinegar in my current thump keg and the new thump keg?
I bet that would work.
Then water run in all, then sac run.

Yes, a new 6" pipe between the 2 thumpers.
And solder joints, it's a copper thumper.
I see you're point.

Thanks ss.

If you run on propane you could do the vinegar with just the thumper and piping to atmosphere then hook everything up for sac run. Thats how i did mine. Electric wouldnt work though.

I like it!
One thing I do see some concerns over is the smaller diameter of your tubing, I'd hate to see you blow a cap by clogging up with some grains in there.

Other than that I love the all copper, thanks for the pics :thumbup:

This! If there were no other changes I'd just load the first thumper with water/vinegar and sacrificial for the cleaning runs.

The tubing is actually 3/8ths all the way from the end of the arm to the money spout.

Pic just looks like it reduces.

Might be wrong. I thought 1/2" was the minimum recommended.

The end of the arm is 3/8", the in/out on both thumpers is 3/8", and the worm is 3/8".

Didn't make sense to up size tubing just to reduce at each piece of hardware.

Do you not get smearing with the copper line drooping in the middle as the pic shows?

I would think not as it's going to the first thumper and still has 2 of them to work through.
I wouldn't do that personally but it's not hurting anything, maybe it's bent like that to make the still work in that specific location.?

I love that little still btw, I'd love to have a small setup like that for kitchen use but I'd use 1" all the way then reduce to 1/2" ID worm. Just because I don't clear washes that well or strain out and bits and pieces get in my boiler and I have more of a chance of clogging.

Very little if any.
Its not as severe of a bend as the pic seems. And the 3/8ths has never been a problem, since I only run cleared washes.

I do ferment on the grain, but I strain and clear for a few days after fermentation is complete before racking to my boiler.
Its a pretty efficient little rig, and I use flexible copper line because I set up in several different locations and need the flexibility of changing the setup from time to time.

I do alot of Rye, and the 2 thumpers come in handy for that as well.
I run water or feints in my boiler, and put the Rye mash in the thumpers to avoid scorching since Rye doesn't seem to ever completely clear.
