Hi all,
I assume most HERMS units use the March pump, rated at 21 L/min. From what I read most HERMS users talk about recirculation rates of 2-3 L/m.
1) Is 2-3 L/m recirculation rate about right?
2) If so, is this done by throttling the pump inlet or outlet?
Last, is there any benefit to continuing to recirculate while sparging? On the one hand I see the benefit of mixing the sparge water with the mash more completely, but on the other hand, does this make the process more of a batch sparge and lead to lower yield? I've attached a diagram of what I'm talking about:
I'd be keen to hear peoples thoughts.
Thanks,
Adam L
