NOVELTY - An integrated biodiesel processor comprises a main reaction tank (12) for storing materials to be processed and within which the reactions take place to form a biodiesel product, and a secondary tank (13, 14) integrated with the main reaction tank for storing first set of reactants to be released into the main reaction tank to cause a first reaction.    USE - For producing biodiesel, especially methyl esters, by a process involving acid catalyzed esterification followed by base catalyzed transesterification.    ADVANTAGE - Integration of main reaction tank and secondary tank allows for a more compact configuration, a cleaner appearance, and the reduction of external plumbing. In the event of plumbing failure, reactants would be contained within the machine, rather than spilling externally. Because it is contained internally, plumbing is also less susceptible to failure due to being hit, punctured, or jarred by an external force.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for biodiesel production by storing oil comprising triglycerides and free fatty acids inside a main reaction tank; storing methanol inside a first tank internal to the main reaction tank; storing methanol and base catalyst inside a second tank internal to the main reaction tank; reacting methanol stored in first tank with sulfuric acid and the oil stored in the main reaction tank to form methyl ester and triglycerides; reacting methanol and sodium hydroxide stored in second tank with the methyl ester and triglycerides stored in main reaction tank to form glycerol, methyl ester and trace contaminants; removing glycerin from the main reaction tank, leaving fuel containing methyl ester and trace contaminants inside the main reaction tank; and washing the fuel to remove the trace contaminants from the methyl ester, leaving a final biodiesel product.
