Cleaning oil with a centrifuge

Melvin Martin discusses the process and results of cleaning vegetable oil for fuel using a cream separator as a centrifuge. He's busy on a multi stage custom unit to be able to clean the oil in one pass after boiling to dewater.

I am very pleased with how clean it makes the oil. The finest dirt it takes out is so fine it’s like grease. I probably could fool you into thinking it was dirty wheel bearing grease. I ran 750 gallons of centrifuged oil through a 0.5 micron Greasel (Golden Fuels) filter bag. It didn’t so much as discolor the filter.
