Todd- Great reply thanks. And thanks to others that responded. You are describing nearly what I have been thinking about. I was envisioning maybe a gravity fed for the coarse matter and then into a heated barrel with a conical bottom with a bung a couple of inches above the coned tip. I only wonder about the availability or ease of manufacture of that fine of a filter... Also I was thinking of forcing air into the barrell to pump instead of an impeller pump.
