On large scale, I have heard of centrifuge being highly effective- the grains are all thrown to the outside of the spin, where a strainer catches them. Weyerbacher employs such a technique.
for homebrew quantity, when I helped my housemate Jim brew yesterday, we used grain in 1-pound grainsocks, and then crushed the socks between two steel pie pans of equal size, first by hand and then by means of a pot of diameter equal to the inner diameter of the pie- liquid losses were minimal and there was no additional particle bits added to the wort. The only limitation is that the grain bags must have no more than a pound each, which makes stirring a bit difficult, and I suppose diffuses less to the water than if the grain was free floating.
I think I have a good 17KW Gas burner that we can use for the next batch as Heat source. I'le have to dig up a propane cyl and see if it fires up correctaly still, its a turky fryer style, one-big-pot burner.
I think I have a Heat-pipe cooling rig at work that will work well as a wort chiller if I can get it, nifty contraption, uses a big radaitor fin on one end to bring prety much anything connected to the other end to room temp in a hurry, no power or running water, and no moving parts. If I cant get that one out of scrap I can build one as long as I rmember.
still not a good filter, but a few more tools for the shed.
that would be awesome. There was a slight innovation made in the wort-chilling, that being the small pot I have fits inside the large pot, which I filled with ice-water and syphoned out/replaced every 20 minutes, your device sounds like it will be much faster.
