The present invention provides a continuous flow method of producing methyl esters and glycerin from triglycerides. Reaction of methoxide with triglycerides produces glycerin and methyl esters, the methyl esters useful as a biodiesel fuel. The present invention takes advantage of the differences in density of triglycerides, glycerol and methyl esters while providing a method of dealing with the unfavorable density of methoxide to achieve reaction separation of the desired products by a countercurrent mechanism. Reactants are injected into a central zone in a biodiesel reactor. Lighter methyl esters rise to the top of the reactor, while higher density glycerol settles to the bottom of the reactor. Ports at the top and bottom facilitate continuous collection of products. The reactor is continually charged with fresh reactant as products are removed, such that a continuous flow system producing biodiesel is provided.
