Ok guys, I will admit that my other hobby (being an ubergeek) is bleeding through here and most of this is just mental masturbation. That said:
If it ever had a purpose, the husk seperator would actually not be that difficult to do. Simply dropping the grain through an updraft with sufficient lift for the husk, but insufficient lift for the grains. The husks would fly out the top, the grains would fall out the bottom.
As for sparging: What if you sparged huskless grain in a LT that could not allow a stuck sparge? I'm thinking a tub like a washing machine on spin cycle. The hot sparge water sprays forth in a mist from nozzles where the spindle should be and sprays at a rate perfect for the sparge. Everything that runs out is wort, and NO liquid remains in the grains. Thoughts?
