NOVELTY - The automated anaerobic digester comprises a bio-fuels vessel and a heat exchanger. The bio-fuels vessel comprises a square or rectangular copper vessel, a stirrer, openings, and a sensor and manure bag provided at an end of an outlet tube. The copper vessel includes a dome formed on a top of the vessel, a gas outlet provided at a center of dome and connected to a gas filling bottle having pressure meter, and an auxiliary outlet, which diverts gas flow at pressure and fills the bottle. The stirrer is fixed at a center base of the vessel, and is moved by motor.    USE - The automated anaerobic digester is useful for producing bio-fuels (claimed) from human excreta and kitchen waste.    ADVANTAGE - The automated anaerobic digester produces the bio-fuels with high yield.    DETAILED DESCRIPTION - The automated anaerobic digester comprises a bio-fuels vessel and a heat exchanger. The bio-fuels vessel comprises a square or rectangular copper vessel, a stirrer, openings, and a sensor and manure bag provided at an end of an outlet tube. The copper vessel includes a dome formed on a top of the vessel, a gas outlet provided at a center of dome and connected to a gas filling bottle having pressure meter, and an auxiliary outlet, which diverts gas flow at pressure and fills the bottle. The stirrer is fixed at a center base of the vessel, and is moved by motor in a clockwise and a counterclockwise direction. An inlet of the vessel is connected to a 60 degrees bent PVC pipe. The outlets of copper vessels are coupled to a u-type bent outlet tube. The sensor intimates at filling of bag by buzzer. The heat exchanger includes a temperature controller, and an insulation body made of plastic and rook wool. The copper vessel is welded with hollow aluminum tubes, which work as heat exchanger. A function of heat exchanger is maintained at a temperature of 55 degrees C. The aluminum tube has an inlet through which hot water is passed within the tubes, and an outlet through which the hot water is removed from a hot water tank. The temperature controller comprises a solenoid valve, a heat pump, a vessel temperature sensor for sensing a temperature of less than 55 degrees C. During the flow of hot water, heat from water is transferred to the vessel. The inlet of the vessel is closed when the temperature of the reaches to 55 degrees C.
