Howdy,
I reckon a thumper combined with plates is a cool setup. It adds functionality we don't have on platers:
Use wash, molasses, syrups, flavoured extracts for rums, or even dissolved DME/LME for UJSMs is something we can't do on platers and it would add lovely complexity to tastes imho. So there's something here of value for Whisky guys as well and that's a bonus.
Solids like citrus etc as well but these could be done on platers. Actually liquids could be gravity fed into a gin basket at a controlled rate something to think about!
Water in thumper to clean spirit seems common as does playing with low wines and it's impact on tails/hearts during the run.
It also addresses my main concern with pot and thumper in that its not soley responsible for gaining abv to achieve a single run. From reading seems most say it's not = to 2x distillations more like 1.5 so guess that questions answered.
Seems inline thumpers as a parasitic boiler won't over tax the main boiler and require only minimal heat increases to drive. I see some play with insulating to achieve different flavour profiles as well maintaining a higher temp in the thumper...good ideas and experience around this point.
A plain pot with a thumper to achieve single runs/ well not for mine but would love to hear from those that do and some confirmation that it can be achieved in a single run. Which clearly leads into the style of rum preferred I guess. I would expect a pot/thumper product to be heavier possibly smeary?
While we're on this thread how the hell do you bleed of fores and heads from a sealed thumper system?
Yeh and mac that picture whilst nice on the eye does it have an internal vapour return from thumper to off take path?
Just in terms of advancing the art/throwing it out there... I was wanting to use a bit of glasser design so 2 solid plates, glass single segment, 8 1cm dia rods for stiffer construction - only 4 using wing nut lock downs, 4"/100mm or 2"/50mm input then a diffuser, 2", external inclined capped feed to feed in fluids/flavourings, a off take so I can see what's going on... more than happy to hear comment here.
