Most impressed, my initial experiments were with a inner pot with a mesh bottom.
I tried 7 mesh (7holes per inch) and twenty mesh the. 7# let a lot of grain matter through and the 20# restricted the flow to a slow trickle.
Neither mesh permitted a flow rate like that in your video, the inner pot just over flowed into the outer vessel.
The level of wort in the outer pot was only 25 to 50mm below the level in the inner pot
One big difference is that I was only returning at the top, I didn't have a return to the bottom.
Do you think that the lack of a bottom return might be the issue?
Is there anything special about your grain crush?
Were is the bottom return positioned relative to the base of the pot?
And of course are there any pictures of the return/outer pot?
I feel some experiments coming on!
