I've been following this thread and am very interested in the way the Braumeister works. A 10 Bar pump is very powerful - if I have the conversion right, 10 Bar equates to about 102 meters (or 334.6 feet) of head, or 145 psi.
This is more than 26 times more pressure than the March809, which has 12.1 feet of head, or 5.25 psi.
Is there anything I have wrong here - is it correct that the Braumeister is using a much, much more powerful pump that the March809?
The other question I have is for all Braumeister owners out there. I've seen the video, and it's pretty clear that the very top surface of the grain has been pressing against the 'false' top' in the grain tube. What is not so clear to me is whether the entire grain bed is also getting pressed against the false top during recirculation or not (just a small surface layer).
For those of you that have removed your grain tube and emptied it, is the grain bed compressed into a compact patty or loose? Any other evidence of whether the bulk of the grain is pushing down on the false bottom or pressing up against the false top during recirculation ? Has anyone ever halted recirculation mid-way (for stuck mash or whatever reason), removed the false top and stirred the grain bed? And if so, I would appreciate a description of what the grainbed was like and where it was located - was it compacted (maybe even into a compressed patty) or was it loose? Was it up high near the false top or down low near the false bottom?
I have no idea what is happening to the grainbed inside the mashtube when liquor powered by that powerful of a pump is being forced up into the bottom of the grainbed, and would appreciate any insight the Braumeister owners out there could provide...
