:Howard, I don't know much about freeze drying. From what little I do know (i.e., freeze a water-containing perishable item, reduce the pressure and add heat to sublime the frozen water directly into a vapor), it is really basically different from flash vaporization. You might think of flash evaporation as the induced rapid evaporation of any liquid or any liquid mixture ... whereas freeze drying is the induced rapid freezing and sublimation of water. Freeze drying really deserves an article of its own. The most mention I think it should have in this article is to include it in the Related Links subpage, which I will do. As for nominating the article for approval, that is up to your discretion.

I was the originator of the WP article. I have gone over it completely to make it into a CZ article. Milton Beychok 12:32, 4 July 2008 (CDT)
Approval?
I had vaguely thought this was already done.
On rereading, a question. Your explanation that spray drying is different but related is quite reasonable. At that related level, however, what about freeze drying/lyophilization? It's something I've done mostly in lab and microbiological pilot plant scale, but is it not at least loosely related? Is there a parallel between the sublimation of ice in vacuo to the other changes of state here? Howard C. Berkowitz 20:55, 1 March 2009 (UTC)
