That type of filter will remove almost none of the yeast solids (but will strip out the corn). UJSM (especially the first run or 2), can handle a little extra time IF kept under air lock.
When I run mine, it is on about a 1 week cycle (with 2 batches going). I do 3 days or so in primary, then siphon off into a carboy, add cooled backset and fire up the primary again. The carboy will sit for 3 days or so (to clear some), then into the still. When I drop that into the still I wash the yeast dregs, and put the new 3 day old primary into the carboy (and restart the primary). Then strip distill, and cycle again.
Thus, I have 2 runs going in tandom, and both get about a week of time to do their magic. The final wash is done fairly well, and somewhat clear (not perfectly clear, but 80% clear).
That is just my method, others can certainly do things differently, and still have great results. With this sour mash method, it really is hard to screw it up.
Hillbilly Rebel: Unless you are one of the people on this site who are legalling distilling, keep a low profile, don't tell, don't sell.
