I have a brew stand that you can see here...
I have always used infusion mashing, but would love to build a simple RIMS. Here is my idea.
I use my Keggle and 55k BTU burner to heat up 5-8 gallons of water to say 190F.
I use my immersion chiller as the circulting device for my wort.
I connect my ball valve outlet from my MLT to a March pump to give motive flow to the wort.
I attach a thermostat device to my March pump, that reads through the wall of my MLT, to control the circulation of the wort.
When I am finished mashing I can pump the 5-8 gallons of water in my keggle, that was used for RIMS to fly sparge my mash.
My empty keggle now recieves my sweet wort, ready to boil.
Does this sound right??
