A method and a device for the production of biodiesel are disclosed. A suitable bio-feedstock may be exposed to microwave energy during a mixing process, a separation process, and a wash process. A synergistic effect of the microwave energy and centrifugal separation may be used in a continuous process for producing biodiesel. The biodiesel may be produced from the feedstock in a continuous flow path. The microwave energy may enhance the reaction of the feedstock and catalyst to provide a mixture of an ester and glycerin, and the microwave energy may enhance the separation of the ester and the glycerin in a centrifuge. Finally, the microwave energy may enhance the wash process of the ester in a centrifuge to purify the ester to produce a usable biodiesel.
