Garfield when I do my AG I use my mashtun to do the conversion then EVERYTHING goes into my 60 litre fermenter which is sealed up with water in the airlock to cool down and when it's about 30C I start with making the yeast bomb.
After the first ferment is finished and cleared I made a 30 micron filter to go on the end of my 1/2" siphon line so none of grain can go thru the line , I do find by placing the filer about 1-1/2" above the base of the fermenter does allow a full charge of my 50 litre keg boiler and when I get to 40 litre mark to keep the siphon going the output goes into a cube as the final 5 litres of my boiler to get a full boiler charge is the same height as the fermenter :angry-banghead:
Then i add 10 litres of water to the fermenter or a tad more to ensure all the grains are under water to prevent them drying out and when I fill the fermenter for the generation the spent grain floats so that is removed and new grain replaced.
so how did your heat exchange project work out mate as I do have a few idea's that are totally out the square that could work to cool the water and on a hot day cool the area too. For background info just think Koolgardie Fridge :handgestures-thumbupleft: The output water is sprayed over some hessian sacks with a decent fan blowing thru the sacks OK it may be a slow process but with 2 olive drums tby the time the second is too warm the water from the first one will be cool enough to use.
