NOVELTY - Automated, mobile biodiesel production facility (A) (100) comprises: a shear mixer (305) operatively connected to a feedstock feed pump, a reactant feed pump and a residence vessel (315); a centrifuge (310) operatively connected to a centrifuge pump, which is operatively connected to the residence vessel; and a control unit (320).    USE - (A) is useful for producing biodiesel and a heavy-phase product, where the biodiesel comprises alkyl esters, which are methyl esters, ethyl esters or propyl esters (all claimed).    ADVANTAGE - (A) is capable of producing 5000 (preferably 14000) U.S. gallons of biodiesel in 24 hours without the need for additional power as the generator burns some of the biodiesel produced. The reaction product self-converts to a residence product at ambient pressure and temperature. The feedstock and the reactant are mixed at a ratio of 4:1 (vol/vol), such that there is no need to provide additional heat or pressure to the feedstock, reactants, or reaction mixtures in order to produce the biodiesel. The heavy phase product comprises less than 5 (preferably less than 2) wt/wt.% of the sum of the feedstock and the reactant mixture.    DETAILED DESCRIPTION - Automated, mobile biodiesel production facility (A) (100) comprises: a shear mixer (305) operatively connected to a feedstock feed pump, a reactant feed pump and a residence vessel (315); a centrifuge (310) operatively connected to a centrifuge pump, which is operatively connected to the residence vessel; and a control unit (320). The feedstock feed pump is capable of pumping a feedstock from a feedstock container to the shear mixer. The reactant feed pump is capable of pumping a reactant from a reactant container to the shear mixer. The shear mixer is capable of mixing the feedstock and the reactant to create a reaction product. The residence vessel is capable of holding the reaction product while it self-converts to a residence product. The centrifuge feed pump is capable of pumping the residence product from the residence vessel to the centrifuge, which is capable of separating a biodiesel and a heavy-phase product from the residence product. The control unit is capable of controlling the shear mixer, the centrifuge, the feedstock feed pump, the reactant feed pump and the centrifuge feed pump to create the biodiesel and the heavy phase product from the feedstock and the reactant. An INDEPENDENT CLAIM is also included for a method of producing biodiesel and a heavy-phase product in (A) comprising: mixing a feedstock and a reactant to create a reaction product; holding the reaction product in the residence vessel while it self-converts to a residence product; and separating the biodiesel and the heavy-phase product from the residence product.
