Re: Finished Stills and Current Builds

Here's a pic of my updated VM still. 4" copper packed column 8" high over a 6" Pro-Cap plate with 2" gate valve takeoff and 9kw of power to blast through stripping or spirit runs. Should produce 2-3 gallons of azeo an hour with a little extra packing. Boiler holds about 18 gallons total and runnable...

A little re-torted

Hey members! Here's my project of the past few years finally shaping up and ready to produce. I'll let the pics do the talking 😉

Re: Fasten your seatbelts. Let's build the Mashimizer !

Let me recommend to swap your idea of a 10" manway, to a 12" tri clamp tri clamp and cap if you can afford it, for hookups to your column down the road.

Re: Finished Stills and Current Builds

This is my first time silver soldering the stainless and I'm glad I finally attempted it. The guy who welds my kegs...

Re: 4 Barrel Gatling Condenser

1. For a 5 way manifold (1 2" input, 4 1" outputs) I was considering getting a 1.5"*1.5"*2" T.C. tee and then branch off the 1.5" tees to two 1"*1"*1.5" tees that would connect to the liebig. This should preserve the vapor path. Can anybody think of a better method? Build a copper plenum (box) out ...

Re: 4 Barrel Gatling Condenser

I'm not pushing anywhere near the power to require such a large vapor path. Only 2000-3000 watts. This is a luxury build, not a necessity. I want the large vapor path to be able to pull off at a lower RR, so that if I want to run something with more flavor than the neutral my VM produces, I can run ...

4 Barrel Gatling Condenser

I've been looking for a way to get a 2" vapor path for my VM column so I can run at a minimum Reflux Ratio of 1:1. Considered buying a 2" shotgun but the area in the vapor tubes is less than 2 square inches, so the minimum size would need to be a 3 or even 4" shotgun. Well these are way more expensi...

bronctoad, it's 11 11/16" ID and 12 5/16" OD. Danespirit, I'm familiar with HETP's and their relation to purity, and the column diameters' relation to take-off. I may move up to a 4" VM column with some plates beneath it, but I want to get a better idea of this beast before upgrading. I made this VM...

Re: Finished Stills and Current Builds

That's the idea, but will it work better with a 6" AND a 4" plate under the column? I've read that the plate feeds it with higher % alcohol vapor, and kind of axts as a buffer to slow vapor speed when applying more power. So with that logic two would charge the column with roughly 85%.I'm just conce...

OK so I ran a mash of cheap vodka watered down to 5 gallons at 20% through my VM head. I packed the column with 22" of this packing with a S.S. scrubber taking up 5" underneath to hold the copper packing in place. When I got into the hearts, I opened the take-off valve wide open, yielding me a r.r. ...

Thanks Mlk man. I can't take any credit for the welds though. I have them all done at a shop. Costs me a little bit per weld, but i can get 3 of em done for less than a roll of Harris Sta-brite 8, so I've avoided trying Bellybuster's method for soldering stainless.

Re: SPP Alternative: Copper Helical Packing

After flattening out the copper tubing to a ribbon, I put one end in a vise and the other end was tightened into a drill chuck and just let it spin until it made a tight spiral, tighter than pictured. I then backed it up just enough to create the small opening in the spiral. This was done in large s...

Re: SPP Alternative: Copper Helical Packing

Didn't really consider that as it would be too similar to raschig rings and may not yield any better HETP's than the mesh I've been using. My thought is that the small gap in between the spiral section will hold water due to it's surface tension, as long as it is not back spread too far apart. Also,...

And yes the VM has it's own coil. 3/8 CSST wrapped in a double helix about 8" long. While the rest of the Boka was just made, that copper coil was one of the first I made, and the last from copper. Copper coils are beautiful pieces of work, but they are too much of a PITA for me to make only to put ...

The 2.5 kW does work well, I just wanted overkill since before I had been using a 1500 watt element on a full keg. Put a foul taste in my mouth about sitting around waiting for it to heat up. Even though takeoff can be slow with the VM, I'm patient since I know that's a matter of quality. And at tha...

All this time and I still don't have a controller! One is 4500 watts and the other is 5500 but until I get a controller, I'm just running them on 110, giving me a total of 2500 watts.

Re: SPP Alternative: Copper Helical Packing

Playing around with it, if it is close to horizontal, the void in the center can hold 6-8 drips of water. I'm thinking maybe due these spirals actually having a solid surface for water to sit on, unlike the wire surface in SPP and mesh, it may increase contact time between vapor and condensate. If n...
