roof not tall enough

I've already cut a hole in the ceiling for my column
Next time when adding another section to the column, I'll have to cut a hole in the roof.
I'm thinking about installing a fake chimney on the roof, for the column to stick up in :lol:

Too bad it's not the bottom that's too low :lol:

Like it! I did something similar when I took a ceiling tile down. I think I'd get in trouble though if I cut a hole in the family room floor :lol: roof would be easier lol

Ya know, a similar idea came to me when setting up downstairs. I'd have to install a 'hatch' in the bedroom floor, but then column height would not be the problem. The missus would be my new issue!

Maybe you could stick it through the wall and people would think it was a stove pipe or downpipe or waste pipe, case it in a plastic pipe or whatever....
Maybe....

Just stick it ontop the shed and call it a folded monopole antenna :wink:
On a side note I've got to get a remote thermometer.

I guess I'm lucky. If I need more height to run my 3" CCVM I simply move it outside on the deck on Wednesdays & Sundays when the neighbors are in church. All day affair for them. :D

A) That's a freaking awesome setup
b) Why not do a split column? Pretty common with the big guys.

Wished you'd have suggested that earlier. I've already started excavating :roll:
All jokes aside, I've been thinking about a split column. and how to return the reflux

http://www.kothe-distilling.com/newsite/stills/vodka" onclick="window.open(this.href);return false;" rel="nofollow <-- fairly typical split column setup

You don't. Defleg at the top of each tower. Once the vapor passes the first column the second column is essentially a new start. I've see Continuous Columns that have an overflow/downcomer type return to the kettle at the bottom of the second column. I'm not sure how you would maintain the equilibrium in any case. I see a lot of opportunity to flood the columns without a return.

If you're serious about it I can ask some of the pros I know.

Seems that alot of distillers run multiple thumpers which could save height. Here is a couple ideas I've had.

1. Use a low height, wide boiler with steam or electric heat to save height by eliminating a propane burner which Is like 10inches or so.

2. Use 2 shorty columns have a pot still head on your boiler plumb to column 1 (no dephlag) running to #2 column which has dephlag. The height should be #1 lower than the #2 and #1 taller than the boiler max fill height so the recoil lines from the columns are gravity fed.

In the past, I've run a packed column on a thumper.
I might make a short fat thumper. That would gain me almost 24"
In this pic, is the "water tank" a thumper :?:

just need a P trap on the returns. return below liquid level in the boiler.

I was considering a trap door that in hidden by a rug in the spare bedroom, it is a dame good idea for fellas like me who are height poor downstairs and don’t own a shed....

I email the only person I know that runs a split column but he never got back to me.

You can control the heat in a column with it. That water does not mix with the vapor afaik. I'm not sure of operationally how it's used.

A cross flow condenser setup horizontally might give you the extra room you need. It would also give you an easy lm option.

First, all you home hobbyists, please take your stills outside of the house. There is a reason why no legal still can be placed in a building containing a dwelling or attached in any way whatsoever to a dwelling. 95% ABV (distillate out of a good rectifying column) produces a vapor that can ignite at fairly low temperatures. Let's not burn down the house. And all you home hobbyists in the U.S., no it is not legal to distill at home. Those NZ units are legal for other activities, but not for making liquor, so maintain discretion if you insist on being a bootlegger. My guess, if you are caught with a functional unit inside a home you will be prosecuted both for making illegal hooch and for violating fire safety code and endangering your family. In house distilling is just foolish. Take it to an outbuilding.
Secondly, with regards to false chimneys and such, if you are meeting all building standards you can not have anything supported from the roof without a building permit. If you have an anal building codes department they will require you to have an architect design any cupola, chimney, or whatever. You can put a chimney vent through a roof without a building permit. Buy the largest one you can find and run the column up through the center of your legal vent. I suggest you wrap the column with a plastic tarp that hangs down over the sides of the roof vent to prevent water leaking through the roof.
I am starting my commercial distillery on a shoestring, so I have one boiler and two columns, one for stripping and one for rectifying. I built a freestanding support for the rectifying column that sits on the concrete floor. I disconnect the rectifier from the boiler and lift it up on the free-standing support, slide the boiler out from under, then attach the stripping column whenever I want to strip. The top of the rectifying column is five feet above the roofline. It is a pain in the ass to climb up on the roof to start, monitor, and end a rectifying run, but affordable.
Please review specs on spontaneous combustion of vapor of alcohol at various proofs and keep yourself safe. Following good practice, my distillate is maintained at proof only until the run has completed and I have a legal gauge, then it gets diluted to around 50% ABV. If I was running illegally, I would start with a gallon of water in the collection pot and add water as the run progressed to keep the proof low. Vapor pressure inside an enclosed building is always a concern. Something as benign as a dropped pot spilling a run all over the floor could result in a spontaneous ignition. (Add water immediate to dilute if you spill high ABV distillate)

Just as an FYI, most of the people in this thread are experienced distillers with years of experience. We fully understand the safety aspects of our rigs: flash temps, ventilation, etc. It's not our first rodeo.

On the other hand, and not to be ornery:

Rodeos are bloody dangerous....

Take a count though of how many professional stills have made head lines vs. hobbiest. And there are far more hobbiest stillers than professional.

Perhaps more professionals should spend time listening to the safety voice on this forum before they go and buy one to play with.

I disagree with the statement that because it's inside it's more dangerous. Inside or out, if you are letting 94% vapor leak, you are already not paying attention to the beliefs of this forum's safety stance. Electric inside before gas outside, imo.

Never leave your still.

Eaglecliffs, how did you get a ttb permit being that your column is 5ft above your roof line? I assume if it's above your roof line your distilling outside and that's kinda of a no go with the ttb.

As for commercial distilleries have accidents there have been a few recently. I'll bet there are plenty of home distillers screwing up but a fire with a 5 gallon still doesn't make the news, a 100 gallon still gets some attention.
