O.K. I am new to biodiesel and new to the forum. I am a small business owner with a few diesel vehicles. I have been dealing with the same diesel prices as everyone else, and have really been thinking about biodiesl. I am really interested in building my own processor, and have been researching the processing procedure. I thought about buying the biopro, but cant put out the money. I have a few reastuarants that i can get my oil, but am still affraid of the shortage that could become. So since I am a plumber and can always get my hands on water heaters really easy, i have been trying to figure out a way of making my own processor. I am a decent welder and up to the challange of building my own. I was thinking of a fifty gallon water heater as a pre heater, then making a processor out of fifty five gallon drums like the murphy machines. I would use there plans for the processor and wash tank. I would like to have multiple wash tanks to be able to process more during the wash cycle, and then the drying cycle i am still not sure on that process. I have been reading various web sites, and most are dealers of processors. I really need a homebrewers input on my questions, not a salesmen. what would be you suggestions. Thanks for your input.
