NOVELTY - Processing kitchen waste using device comprises crushing kitchen waste into slurry and then introducing in methane producing reactor and diluting using water to designed thickness, circulating anaerobic digestion liquid phase, performing hydrolysis acidification stage and methane production stage in an intermittent operation mode, introducing the slurry into a hydrolysis acidification reactor through a feeding pump after diluting and discharging the feed liquid through hydrolysis acidification reactor outlet, and controlling retention time for 9 days.    USE - The method is useful for processing kitchen waste (claimed).    ADVANTAGE - The method is capable of effectively processing the kitchen waste with high stability.    DETAILED DESCRIPTION - Processing kitchen waste using device comprises (a) crushing kitchen waste into slurry and then introducing in methane producing reactor and diluting using water to designed thickness, and circulating anaerobic digestion liquid phase, (b) performing hydrolysis acidification stage and methane production stage in an intermittent operation mode, introducing the slurry into a hydrolysis acidification reactor through a feeding pump after diluting and discharging the feed liquid through hydrolysis acidification reactor outlet, and controlling retention time for 9 days, (c) of introducing kitchen garbage through a liquid circulating pump I into anaerobic digestion process at the speed of 100 ml/minutes and then recycling using hydrolysis acidification reactor, (d) performing intermittent operation mode of the anaerobic digestion liquid, discharging anaerobic digestion liquid phase into hydrolysis acidification reactor and then introducing into methane production reactor through the feeding pump, discharging the liquid through methane production reactor outlet by liquid circulating pump II at a speed of 50 ml/minutes, again feeding the liquid into hydrolysis acidification reactor and methane production reactor, where the an upper phase liquid of the is recycled and stirred, and (e) introducing the liquid of methane generating reactor into a gas metering device for reading gas quantity.
