I *&^%$#@ HATE stuck mashes!

The problem is related to a shit crush. My system works great about 99% of the time, unless I happen to purchase malt for a certain supplier. Too much flour gums up the whole bed, and doesn't allow for drainage.

Apparently there are also benefits when continuous sparging as the reduced stiring results in less air being knocked out the grain causing it to float better.

Is a floating grain bed beneficial? I've always knocked the air out of the mash so that it sinks when sparging and forms a filter bed.

I think the theory is that not knocking all the air out of the grain will ensure that it doesn't pack down too hard on the fb/manifold causing it to block.
