NOVELTY - The device for producing biodiesel, comprises a microwave device to provide microwave energy to a chamber, a reaction vessel (50) positioned within the microwave chamber (20), a first separation apparatus in communication with the reaction vessel and positioned within the chamber, and a second mixing and separation apparatus in communication with the first separation apparatus and positioned within the chamber. The reaction vessel includes static mixers. The first separation apparatus comprises a first centrifuge (60) for initial separation of an ester and glycerin.    USE - The device is useful for producing biodiesel, which is useful as an alternative for petroleum-based diesel fuel in automobiles or other vehicles.    ADVANTAGE - The device is a large scale batch or continuous system thus rapidly producing biodiesel with less in-process feedstock and reagent inventory, and is highly portable.    DETAILED DESCRIPTION - The device for producing biodiesel, comprises a microwave device to provide microwave energy to a chamber, a reaction vessel (50) positioned within the microwave chamber (20), a first separation apparatus in communication with the reaction vessel and positioned within the chamber, and a second mixing and separation apparatus in communication with the first separation apparatus and positioned within the chamber. The reaction vessel includes static mixers. The first separation apparatus comprises a first centrifuge (60) for initial separation of an ester and glycerin. The first centrifuge comprises a first outlet for a first denser material and a second outlet in communication with the second mixing and separation apparatus, and removes the first denser material from the chamber. The second mixing and separation apparatus is a second centrifuge having an inlet in communication with an outlet of the first centrifuge, an inlet for a washing agent and first outlet for first denser material. The second centrifuge removes the first denser material from the second centrifuge and the chamber, and comprises a second outlet, a housing, a rotor disposed within the housing, an annular region defined by an inner wall of the housing and an outer wall of the rotor and in communication with a first and a second inlet, and a chamber disposed within the rotor and configured to separate the first material from a second denser material. The reaction vessel, the first separation apparatus and the second mixing and separation apparatus are transparent to microwave energy and mutually configured in a continuous flow path, and comprise a polymer, a plastic, a water-free ceramic, a quartz, a carbon fiber or a glass. The biodiesel production device has a weight and volume of less than 200 pounds and nine cubic feets respectively. The continuous flow path is configured to produce 1-12 gallons per hour of biodiesel, and to accommodate an in-process inventory of 1-5 gallons. The second mixing and separation apparatus comprises two mixing and separation apparatuses configured in a series. An INDEPENDENT CLAIM is included for a method of producing biodiesel.
