Seems a fair summary.  :)

I'm not sure I understand which specific honey-drying process
you are describing.  The only processes I know of are the
"low-end" processes that a beekeeper might use:

a) "Thick Film of Honey", where a shallow tray is filled with
   honey, and one dehumidifies the air to draw moisture out of
   the honey.  Takes lots of floor space, and difficult to keep
   clean and dust free.

b) "Vacuum/Flash Heat", where the (partial) vacuum lowers the
   "boiling point" of the honey, and the flash heater, heating
   the honey to some "reasonable" temperature that is hoped to
   not hurt your HMF or diastase numbers) boils off some
   percentage of the water content.  Very cool, but not cheap.

b) "Thin Film of Honey", where one creates maximum surface area
   for minimum amounts of honey, and dehumidifies the surrounding
   air. (The rotating disks in a tank approach seems to me to be
   a great use for all those LP records that have been replaced
   by identical CDs, but I have yet to build one.)  More cool, in
   that one need not heat the honey at all, not much floor space,
   and no need to sustain a vacuum, so this is clearly the way to
   go for anyone who does not have a multi-million dollar "plant".

None of these processes will "filter out" anything, and while the
ones using heat will certainly evaporate out some volatiles, I can't
imagine any of them creating "non-honey".

So which process are you thinking of?
Some sort of very fancy catalytic process?
