Device for producing carbon source by using kitchen garbage

The utility model provides a device for producing a carbon source by using kitchen garbage, which comprises a crusher for crushing the kitchen garbage to form slurry; the extruding machine is used for extruding the slurry to form slurry; the three-phase centrifugal machine is used for carrying out three-phase separation on the slurry formed by extrusion so as to separate solid-phase solid residues, oil-phase grease and liquid-phase slurry; the fermentation tank is used for fermenting slurry which is subjected to three-phase centrifugation and is inoculated with a lactic acid bacteria seed solution; and the centrifugal dehydrator is used for carrying out solid-liquid separation on substances generated by fermentation to form centrifugate compounded with organic matters. According to the device for producing the carbon source by utilizing the kitchen garbage, provided by the utility model, the efficient lactic acid bacteria seed liquid is introduced, so that the fermentation process is stable, directional lacti
