Re: Flash Distillation
- Max (and Joe),
When you sat "stripping" it sounds like you mean stripping all the volatiles from a mixture of volatiles and non-volatiles, as opposed to the distiller's use of "stripping" as collecting most of the volatiles (and leaving much of the water) from a mixture of volatiles and non-volatiles? The former is what I found described in my research. I was ok with that, but it was of no use to a beverage distiller.
Actually from your background I'm interested in what you have to say about flash distillation, for a couple of reasons. What you are saying does not appear to violate any of the physcial laws that have been issues earlier, and that you also predict the accumulation of ethanol/water mixture in the condensation chamber when spray emergy is reduced. My skull-modeling also predicted that.
I'm really not against closing our minds to "new" ideas, but I need to see them backed up by references, experience, or physics. Otherwise, it just drives the forum nuts.
Thanks for your input, Max.

If you try to lower the temperature in such a way to separate water from ethanol you will have a pool of water/ethanol building in the bottom of your vessel. Once you are "there", if the time spent distilling is your major concern, then you have to pose this question to yourself: "Is there a better/cheaper way to accomplish this ?"

- I just wanted to tell someone since I dropped the flash distillation subject on Distillers.
I figured out how to use it for stripping, and how to use it for making cuts. It will cost around $1,000 to build though. Now the subject is officially dead for me.

Message from Management to "last2blast"
Your posting privileges have been demoted to "moderated".Reason:
Due to excessive badgering by you of both the Y!D forums, re your "new distilling idea".Whether it works or not, isn't the issue.
Harassment is the issue. Harping on unfounded and untested notions is the issue.You've had more than a fair hearing in BOTH groups. Now it's time for you to "put up, or shut up". When you are ready with the results, post 'em. Mods will see if you're contributing to the distilling topic, or just continuing to blow steam. Your post will be dealt with on that score.Footnote:Part of The Charter for this group states..."It is a 'given' that you are familiar with basic distilling."I strongly urge you to get educated re Distillation before you continue. Else you're gonna do yourself a mischief.
