So I would consider myself an intermediate brewer making a slow transition into the advanced realm and I am having some issues with my mash tun.. I have a three tier "brewing sculpture" that I made out of wood. It isn't perfect but all in all I am very happy with it. On the top tier I have my 10 gallon brew pot/mash tun complete with a ball valve spigot and thermometer installed into the side, this sits on top of a burner, on the second tier I have my 10 gallon converted orange Rubbermaid lauter-tun with a false bottom, and finally on the bottom tier I have my 10 gallon converted HLT. When I brew, I mash in up top in the brew pot and when everything is converted I transfer the mash to the lauter tun and you know the rest... When I was designing this system I pictured the mash being transfered to the lauter tun from the brew pot via the ball valve spigot but I have realized that the mash tends to be too thick to even flow through the ball valve and I am forced to pick this hot and heavy piece of steel up and pout it all directly into the lauter tun which of course adds oxygen to the mash which is undesirable. Does anyone have any suggestions as to what I should/can do to remedy this problem? I was thinking about shopping around for a wider ball valve or to attach a hose filled with water to the end of the ball valve to create somewhat of a siphoning action to help pull the wort from the pot down into the lauter tun. Anyway, any suggestions would be greatly appreciated. Cheers.
