A manual A cleaning spray gun is provided to facilitate manual cleaning of the device. A Forma wheel is installed at the bottom of the shell 1 to facilitate short-distance movement of the device. The chain plate unit 2 performs the initial solid-liquid separation on the food waste entering through the first feed port 101 on the shell 1, and then the solid phase is sent to the shredding unit 3 for crushing. The crushed solid-phase food waste enters the solid-liquid separation unit 4, and is subjected to secondary solid-liquid separation by extrusion. The separated solid phase is discharged from the discharging unit 6; the liquid phase initially separated by the chain plate unit 2 and the liquid phase secondarily separated by the solid-liquid separation unit 4 are both discharged into the oil-water separation unit 5, and the separated oil phase is discharged through the oil discharge port 5018.
