- Oct 2, 2002Hello Motie
What your are trying to do is a little different than my original idea.
I wish you the best of luck. To spell out my idea, I know where I can
purchase two popane tanks, a 500 and a 1000 gallon tanks that were
damaged in a grass fire. Plus I have 2 very good 1000 gallon popane
tanks that could be used as vacuum storage that I don't use. The plan
calls for cutting off one end on each of the damaged tanks. Welding
them together to make a single 1500 gallon tanks. Cut out a access hole
on top and make a clamp on lip to cover. Grain could be augured in
through this hole as well a maled barley. Water would be pumped in to
fill the tanks and then inject steam to cook the mash. After cooking
circulate the wort through a heat exchanger to cool it down to yeast
temp and then pitch the yeast. As I said it is getting colder here
everyday so any radiator with a fan on it would work quite well. When
fermented, apply vacuum, suck off any alcohol that happens to be in
there. Drain the fermenter and then apply vacuum again this time to dry
the spent grains so they will store longer. A removeable lid on the
bottom ( same as the top) to dump out the dry spent grains. All DDG&S's
would still be in the dry spent grains. Probably give the cooker a good
cleaning and augur in more grain. Simple and easy, no fancy machinery,
low initial cost. Boilers are simple to make as well and a condenser
would also be very easy to build. Only real expense would be a vacuum
pump capable of pulling the vacuum needed. Use a good yeast and add lots
of it and I could turn this thing over once a week.
A 1500 gallon fermenter with a 14% wort would produce 210 gallon of fuel
alcohol. Us a higher alcohol yeast and get it up to 18% and I would
have 270 gallon of 100 proof fuel with no drying needed. Find some
gasoline with no water in it and I'm ready to make some gasohol.
On the question of whether or not I would need to up the vacuum or heat
as the percent alcohol in the wort comes down, consider this. A reflux
still will heat up slowly until you start removing the fore shots. As
they disminish the still will heat up until you start removing the
ethanol. Their it will stall out until the ethanol has been removed
(the more heat you apply the faster the evaporating ethanol will carry
it off) When it runs out of ethanol it will start heating up as it
starts to remove the higher alcohols. It will do this heat and stall
thing until you start getting water. Would this not be the same for the
vacuum still. If the vacuum and temp where held at the same levels would
it not just stop producing ethanol. I would think that for fuel alcohol
the foreshots and the tailings would burn just as good as the ethanol.
If anyone knows any different I would appreciate hearing what you know.
So, tell me what you think, am I completely off my rocker here
