use still as HLT?

Recommended Posts

where space is at a premium do you foresee using a still to heat up water an issue? then pump it to the Mash tun? I am realyl short on space and wnated to avoid having a HLT if at all possible.

I am planning on using unmalted winter wheat and enzymes

  • Heat water in still
  • Pump to mash tun
  • run mashing protocol
  • sparge and pump to fermenter
  • ferment
  • pump to still
  • stripping run

I will use a jacketed mash tun, but how would that avoid pumping? surely i have to remove the wort off the grain to ferment it? (if not distilling on the grain)

But yes, mashing out then fermenting and distilling on the grain would certainly save a lot of hassle.

Trouble is the target still is only 100l, has an internal element and no agitator. Also, I am planning on fermenting 400l of wash, to give me 3 x 100l (or so) stripping runs that could then be combined to 1 spirit run.

I know a local brewery that uses multiple tankless water heaters in series to get to hot enough water for mashing malt for a 5bbl mash tun.

Also consider distilling on-grain.  You're making vodka not single malt. 

Otherwise, yes you can use your still as hot liquor tank.

Actually if it's no detriment I could ferment 300l on the grain, and transfer to my 300l pot still. Strip on the grain. Then spirit run on my 100l vodka column.

Thoughts?

Is stripping with grain, dead yeast etc. acceptable?

We strip on-grain, as most distillers do with the exception of some single malt distillers, then do a spirit run to make cuts all on our pot still.

We then redistill the finish in our vodka still.  

This approach makes your vodka super clean.

makes my life soo much simpler! awesome. I was having trouble getting a mash tun to my spec. It will be much easier to find just an insulated FV to handle the mash and ferment.

Follow up question, and forgive my lack of knowledge on this subject. Wouldn't making cuts on the 2nd pot run make those cuts quite wide? whereas if you make them on a stabilized vodka column the cuts might be tighter?

I wouldn't strip on grain if you are using a still with submerged electric elements and no agitation. Both the distillate and the still will be a scorched mess.

Change of plan, I'll strip with My 300l pot still which is baine Marie and has an agitator

Heat up times with the baine marie may be painful, but it's definitely preferable to the alternative. Are you too far along to run the still on low pressure steam?

Not only too far along I don't want the hassle of the system inspection nor the cost. Plus I don't have the space. See my other thread for my floor plan

making cuts slows down the run because you have to worry about smearing. The operating premise is strip first really fast, then fractionate in your finishing runs. If you have a column and know how to run it it is exponentially faster to vent off methanol and fores in your column run and work with less heads fro your fractionating run. If you don't know what I mean from that sentence alone just save it for a few years you'll get there. I will not go into that statement if you can't figure it out now your not ready for it.

 

It seems you re very green. Maybe instead of trying to make things go fast, you learn the basics first.

I have run a column with SPP before and when well equalised I did have good compression on the fores and heads.

I was merely questioning the sense behind making cuts on a pot still on a previous comment, i think we agree the best place for cuts is a column of some description.

Continuous column and batch column are no where even close to the same in operating premises, pardon me if I'm over assuming but your column doesn't even have vents so you can't do what I said so we cannot agree. Our disagreement is a fault of semantics: column on a batch distillation system is still a pot still even if you're running a packed column on it. The premise of stripping is a batch distillation premise/function, even though some people do have continuously run stripping columns. Stripping from a batch perspective works really well in the craft model because depending on who you are and what you're working with you can turn two strips a day, so if you had four fermenters it could actually take less time (taking into account actual shift work, working days, and turn over) to strip twice a day and run it all in one finishing run then to fractionate every run individually. Most people wouldn't be able to even get 4 fractioning runs off grain in a week I think they'd go bananas because they'd have like no yield. Come to think of it none of my lecture has even mentioned positive effect on yield of stripping and finishing wines vs fractionating on grain run. As the amount of water in your batch decreases so does your tails purgatory. A pot still is a pot still is a pot still. A column powered by the individual heating of a single batch is a pot still. I think the name most often used for the pots with the 4-5 plates on them and a depgh is a "hybrid potstill." Continuous columns, in short known as columns, are continuously fed wash and work very differently than a hybrid pot.
