Recently I have had trouble with stuck sparges. When I used my 10 gal. Igloo cooler M.T. I never had a problem with a stuck sparge. Now I have gone to an all electric brewing system and my M.T. now is a 20 gal. Blichman with mash plate. Ever since I switched to this new M.T. I have had stuck sparges on a regular basis. I adjusted my mill to .042 gap, thinking a courser grind would help, but not really. I really don't want the added expense to add rice hulls to every batch of brew. It doesn't matter what type of beer I brew, or grain I use. The sparge is pretty well stuck right from the time I open the valve to recirculate the first runnings. My sparge water is at 180 degs. I always wind up blowing back through the valve mutiple times to get the sparge to start, something I really hate to do. Any suggestions would be appreciated. Thanks!
