I am trying to get a better understand of the proper way to go about my equipment and advance settings dialed in.
My setup - 3 vessel all grain Rims. Boil kettle 20 gallon Blichman G1 Mash tun 20 gallon Blichman G1 w/ Blichman false bottom, HLT 15 gallon Blichman G1. HLT and BK are gas fired. 2 chugger pumps and 5,500 ULWD heating element ( running on 120V so +/- 1,400 watts) for rims tube.
I have measured my true dead space ( unrecoverable water left under false bottom) = .1 gallon. I have .5 gallons of recoverable mash dead space ( pump, lines, rims tube).
Process- Mash in recirculate for 60 min. and drain to BK. Add sparge water, stir, recirculate 10 -15 to clarify and ramp temp to 168 for mash out and drain to BK - AT THIS POINT I would like to hit my pre-boil volume - I do not want to go and chase the last .5 gallon that will still be in my rims tube and lines leading into MT ( I know I could pump additional water from my HLT thru the lines to push the wort into the MT before draining but prefer not to.)
SO my question is - Do I need to change my dead space to include this .5 gallons ( so it would now be .6 gallons) that is left in the system and at the same time decrease my recoverable dead space to 0 ? If I do this will it effect my water to grain ratio in the mash ( I believe the purpose of the recoverable mash dead space is to help keep your water/grain ratio in proportion).
Question 2 -
to compensate for the above scenario I have been increasing my grain absorption number . If I make the above changes should I go back to the standard .96 fl oz/oz and use an excel sheet to track and adjust absorption and adjust accordingly?
Thoughts comments will be appreciated.
