Okay, here's my way of setting up a Batch Sparge Schedule in BeerToolsPro:
First, go to “Display>Schedule” and Create a “New>Mash In”. Call it “Mash In”.
Double click on the new step or hit “Edit” and... Enter your “Target Temp” and “Infusion Rate” and the program will do the rest of the math.I set the “Vessel” to my mash tun because the volume displayed in the main window is the total mash tun volume.
Create a “New>Rest”. Call it “Saccharification Rest”. Hit “Edit”. You should only need to enter the “Duration Time”.
Create a “New>Infusion”. Call it “Mash Out”. Hit “Edit”. Set the “Target Temp” and play around with the “Infusion Rate” until you get something you like. Hit “OK” and reopen the window, this will sometimes refresh after you close the window (seems to have a bit of a glitch and needs a “lock” box, but it works.) The Final Volume” displayed in the main window is the total volume of liquid and grain, so you know if it will fit in your tun. Adjust accordingly, this seems the scetchiest part of this process, so far.
Create a “New>Collect”. Call it “First Runnings”. Hit “Edit”. I set the “Vessel” to “Boil Kettle”, because the “Final Volume” displayed in the main window will, from now on, be the volume collected to boil. Set the “Sparge Volume” to “0” and it will display the Runoff in this and the main window. The tricky part here is to then set the “Residual”. Either set it to 0 to get the total unabsorbed volume, or set it to the void volume of your tun. Hit “OK” and the volume in your main window will display your first runnings.
Create a “New>Collect”. Call It “Sparge 1”. Set “Sparge Temp”, “Sparge Volume”, and “Residual”. The sparge runoff will display in this window. Hit “OK”. the total collected volume will display in the main window.
Add another “New>Collect” if you, like me, want to do a “Sparge 2”. Edit accordingly.
You can then go back and manipulate the volumes until you get roughly equal runoffs if you want to optimize your proccedure, but watch those “Residual Volumes”, they’ll change as you change “Sparge Volume”, and you have to reset them or you’ll get screwy “Final Volumes.”
I hope I remembered everything and this gets you started.
There might be a way to use Infusion step as sparge steps, I'm just passing on the method that worked for me and fit the way I think about these things. I used this Saturday and hit all my numbers almost spot-on.
