Re: Another VM Head - Comments Criticisms??!?!

Don't take it personaly. Its just that so many men have been there and done that, before both you and I, that most ideas have been tried, in one way or another. The internet has been able to bring a lot of these ideas together. You can easily learn from the mistakes of others, without cost. Can sav...

Re: Another VM Head - Comments Criticisms??!?!

Ok, I take the hint . 'Back in your box newbie' :oops:. Probably best if I leave this thread there then. Since originally posting I have found (and been directed) to a lot of discussions and construction techniques on proportioning VM heads (including this design). I am happy to say in the end this ...

Re: Another VM Head - Comments Criticisms??!?!

No in principle problem with the idea of a proportioning valve, but it is tricky to actually build a valve like that from scratch. And the correct link to my drawing file is: http://homedistiller.org/forum/download/file.php?id=7370 Thanks Hookline that's a very worthy document! I suppose you end up...

Re: Another VM Head - Comments Criticisms??!?!

I have to agree with the added complexity issue... I also don't understand the the thinking behind a 10:1 reflux ratio being the ideal... Considering how you can attain 95% ABV with a few as 4 HETP's, although it takes a lot more work to reach 96.5% ABV, that ratio shouldn't be considered a carved ...

Re: Another VM Head - Comments Criticisms??!?!

I think the fixed 10% slit theory for 10%/90% is flawed... Path of least resistance comes to mind immediately but there are more issues that I don't have time to delve into right now... Thanks Rad, Yeah the slit was probably not my best thought. As I said to Bushman it was designed to deal with som...

Re: Another VM Head - Comments Criticisms??!?!

What issues are you referring to with a coil and liebig condensers? I believe you are making it way to complicated with 2 coils and through research we have improved on an offset head design which yours is a variation of. Also I do not understand how your inserted pipe valve with orifice is going t...

Another VM Head - Comments Criticisms??!?!

Hi all, yes another newbie throwing out a new idea for a VM head. Hopefully the drawing is fairly self explanatory. The idea being that the reflux ratio is controlled by an inserted 'pipe valve' with a 10% orifice. Turning the pipe valve allows you to select full reflux (ie product condenser closed)...

Re: LM with Flow Independent reflux ratio?!?!

Hi coaster, I'll have to look up the VM/LM options. As I mentioned to rad I suppose I was trying to better understand the theory by asking whether a constant ratio split of reflux condensate (if it could be done) would be equivalent outcome to a VM. Rad has mentioned the column equilibrium issue whi...

Re: LM with Flow Independent reflux ratio?!?!

Thanks rad14701, Hmmn I might have to get my head around RLM a bit more as from what I understand this simply puts the reflux into a constant rate instead of the product. Hence at initial take off product is highest and dimishes over time. Doesn't this suggest a change in ratio over time? I notice y...

LM with Flow Independent reflux ratio?!?!

OK so I am new to the world of distillation but I have taken the advice for this forum and read and re-read article after article. And I probably have a lot more reading to go so please feel free to send me back to reading if need be! :) Looking at reflux designs and from what I have read (emphasise...
