Neutraliser ABV
![Post Post](./styles/proFormell/imageset/icon_post_target.gif)
Got my shiny new Neutraliser a few months ago, I've done 3 or 4 gens of CFW,WBAB,BWKO,& Rum all on 4 plates - all is good with the world.
But when I try to run it with 5 plates and the packed section to get a neutral, the ABV starts a litle low at 93% then starts to gradually dercrease down to 85% or so before the wet cardboard smell of tails becomes pronounced. Reading on this forum, I was expecting 94-95% all the way into tails.
I did call Allan, he suggested that I repack the column, which I've done, I now have 2.6kg of copper in 4 'sausages' very tightly wedged in.
I've been over it with a mirror - no leaks. I've tried several washes (TPW,FFV & Kale) same results. The estimated yield and the resulting yield seem to be about right.
Prior to todays run the still was stripped down and cleaned, shiny copper and stainless.
Todays run of 57L of Kale (OG1065,FG995) @ 9% should have given me around 4.9L@100%.Brought to boil with 2 x 2400W, then 1x2400w.
After 200ml of FS, I collected in 16 x 250ml jars @ 1.8L/hr (ABV from 93 -->85%) then stripped to 20%, RC off and 3600W
The cooling water went from 15 - 17.5degC.
Total collected (including 3L of tails at 32%) at 100% ABV=4.7L, so pretty close to what was expected.
Previous neutral washes have been similar, but if I try to run at 2L/hour, the same thing happens with the ABV but there's definate smearing in the distillate.
Any one got any ideas on what I'm doing wrong ?
