Pretty cool device. I wouldn't have expected something like this to increase efficiency.

Nice call on the ice cream motor....I heard that distinct making ice cream noise that only those motors make. Good idea

Nice job! Ever since seeing The Pol put one of these in an igloo I've always thought about incorporating one in my system. This might push me over the edge

The ice cream maker motor works perfect and is just the right speed. The shaft is made from a sanke keg stem. The paddles are plastic spatulas. I'll post some pictures of it taken appart a little later. I've brewed two batches in this setup and got 85% efficiency each time. Before I got around 70%.

Post back and let us know what the beer tastes like. I've heard several times that as efficiency rises too far, so does tannin extraction.

There's not a direct correlation, as you can get high efficiency without extracting tannins, but yes, that certainly can be a big side-effect of the race for higher and higher efficiency if not done properly
