(note; i'm copying this to the BioDiesel list since no-one else has yet
on the chance that there's anyone there that's not here and might want
to participate.)
interesting theories, Luther. i guess i just don't seem to see any
of the problems you allude to being possible.
notes: i was taught to position the re-entry flow so as to create
and maintain a good swirling action in the mix tank; seems to work
pretty effectively.
i was also taught to try to make sure the methanol/methoxide is well
mixed before use, and to trickle-feed it by gravity into the pump;
reaction is immediately and dramatically visible in the clear tubing
downstream from the pump, and i don't see any reason to believe it can't
continue in the swirling of the reaction tank.
reaction time doesn't seem to be much of a factor for most home
brewers i know; it's already a sort of 'set-and-forget' timed process at
each stage anyway.
what advantages are you seeing to the sealed/stirred reactor type
you mention? to be fair, could you also address what downsides there
might be (aside from its additional complexity) and what kinds of costs
are associated with it?
cheers/73!
