Recirculate throughout mash

I place milled grain in my mash tun, underlet, then begin recirculating thru my RIMS. As the mash progresses it get clearer and clearer.

I do not know why your mash does not clear by the end of your mash. Possible your milling too fine creating too much flour?  Just spitballing.

I don’t know what it means to “underlet.”

I’m trying to accomplish two things with this post:

1. Figure out why my grain bed settles the way it does - terrible drawing below.  I know the reason I have particulate passing through the pump is the grain bed is very thin at the edges of the MLT.

2. Determine if the mash-in technique described in my original post is common or not, and find out from someone who has done it how reliable it is.

Again, use a grant. If you are pulling on the grain bed with the pump that is most likely the problem.

Or just put a valve and throttle on pump out.
