Doubling distillate volume with equal sized thumper?

Postby telefonica » Sun Apr 14, 2019 1:20 pm

I have a converted 15.5 gal keg that I use as a boiler for my pot still. Recently, I've been considering adding another 15.5 gal keg as a thumper. Is my understanding correct that I could effectively double my output by doing so? Essentially, my stripping run would be 10 gal of wash in both my main and thumper, and my spirit run would be low wines equally split between my main and thumper? By doing so, I'd be doubling my output?

That's not how it got the name "doubler", correct? My understanding was that it got that name because it would increase (or possibly double) the ABV.

Thanks!

More or less, yes.
To heat up the thumper the boiler has to transport a certain volume to the thumper. This enhances both the volume and the ABV in the thumper, so the ABV leaving the thumper is higher than the ABV leaving the boiler, and the thumper will also be more filled.
Truckinbutch uses a boiler and thumper that are both 15 gallons, if I am correct. I use a boiler and thumper of 10 liters. Among other uses for running 15 liters of wash: 8 in the boiler, 7 in the thumper. Less low wines of a higher ABV in one run.

A preheater gives you multiple strips with only one wait for heat up.

I ferment 30 gallon AG batches . That normally yields me 12.5 gallons of clear yield for my gas fired boiler . Straining and squeezing the remaining mash will yield approximately 12.5 gallons of cloudy mash for my thumper . Do a couple of strip runs of that and you have enough for a large spirit run where you do your cuts and blending .
Don't forget to cut what you rerun to below 40% before running .

Don't drink water , fish fornicate in it .
