inline thumper on a 4"column

[BIG D]

Hey, just reread my last post, I meant 7 liters @ 65% (once watered down to oaking strength)...

That is golden man. My wife just bought a $250 handbag (with my blessing!) For me to be able to work the thumper into the budget - although, the line: "its a gift for us" did NOT work. Lol.

Have you found any difference to flavour while using it? Better? Worse?

I find with the extra heads and tails compression I can make it piss like a race horse and in turn more flavour is passed over , however if I setup for a neutral run I load the thumper and then just run it slow and the results are equally as pleasing. :handgestures-thumbupleft:

When you run an inline thumper what happens what's in the thumper at the end of the run :?

Not a great deal mate just a bit of real low proof tails I only strip to 20% after my last cut.

Thanks heaps for your knowledge, Big D - this thread is THE reason I'm getting one.

Big D,

How'd you go with running 4600w (after reflux)? All good?

[BIG D]

Yeah mate all good I reflux at just over 2400w and then I wind up the power to overcome the rc leaving the water at full flow. :handgestures-thumbupleft:

Is that running 'power management'?

Since getting a controller I've often wondered what it would be like to run like this.

[Atreu]

So how did you know to stop at 4600? What would happen if you went to 4800w?

Sure is give it a try. :handgestures-thumbupleft:

The bath depth on the 1st plate starts to get a little high.

Power management works quite well when using the thumper, another thing to consider is because you're not returning distillate to the boiler it will be boiling at close to 100c once all the distillate is held in the thumper ;-)

[Professor Green]

It's a slightly crazy idea I know but could you put macerated botanicals in the thumper? Just seems like a good spot for them where they could continue to infuse with the hot spirit but not get burnt by direct heat like they can do when placed straight into the boiler.

Cheers,
Prof. Green

Hi Big D,
Sorry for all the questions, I'm just really trying to understand what you're saying. :oops:

So, increasing the power to much will fill the thumper faster than the distillate can be taken off, therefore it'll drain back to the boiler, slowing things down, yeah?

If that's the case, the idea then, is to fill the thumper to just under the top of the downcomer, and give it just enough power to keep the bath level at the same height, while the takeoff rate increases... Thats the balance we're looking for... Am I on the right track?

Sorry mate I was referring to the first plate above the thumper. :D

I find once i fill my thumper I then power up and take off as quick as i can (overpower the rc, thats on full flow), usually 6-7ltrs hour until my abv drops below say 91% and my thumper level drops then i power down and reflux again, repeat if you don't have enough capacity to get all your alc into the still. I do this until the thumper starts to fog for me usually twice, then you know your pretty much done. This is just my experience with my thumper anyway.

Nice one meat! :handgestures-thumbupleft: Any pics of inside cap/riser?

ive been waiting for that. :text-lol: :clap: nice

thump plate (600x800).jpg

Bottom plate.

Riser 2 1/4" SS
Cap 3" copper on right.
drain is 3/4" with a 1" funnel, j-trap extends up the riser.- drain depth can be changed higher or lower if running 1-2 plates.
3/4" drain at the bottom to be used with triclamp tap.(left)

top plate to completed.

Im trying to figure out just what you guys are saying

So have it on an average distilling power, i havent got a rig like yours so im going to do an example like 2.4kW. then have in full reflux until there is only alc in the column including thumper. Then when you want to collect you power it up a few kW and maintain full reflux water flow but the extra power pushes the vapor through? and you power up until you get the 6 or so L/h?
How long do you need to do full reflux for to get the water out and separate the fractions better?
Is this correct and is this a flavored wash or neutral?

The flow rates sound really good for a 4" rig with a thumper
