I've been toying with the idea of doing what I call an Inverted HERMS (iHERMS? lol).
You recirculate your mash liquid but it does not go though the HLT. It just recirculates from the bottom of the MLT to the top. There is a coil in the MLT that hot water is pumped through.
My theory here is that it would provide more equal heating of the mash and allow for better step ups in temperature in the mash.
It would require an additional pump for the hot water, but not necessarily food grade if the water was heated separately from your HLT. (If using your HLT as the water source then you would want a food grade pump).
Has anyone done this? Thoughts?
I probably won't get around to doing this for a while. I've already spent to much on things lately.
