Finally ran a batch of unwashed bio through the centrifuge. Maintained about 80 - 100 psi and saw a bit of mist (evaporation of residual moisture?). Fuel ended up quite clear and clean looking. Did the 27-3 test on it, which I have not done to washed bio, so no comparison on that yet. I got a tiny bit of settling from that test, so now will run a 27-3 on some washed bio and check that out. Any advice on testing? I typically just do a visual (sparkling clear bio) and possibly a sizzle test.
