In a typical family home, the invention is positioned in the sink and performs the following operations: when generated food waste is put into a hopper and injected into a cylinder which is the concave part of a grinder, a rotor formed with a screw on the outer surface thereof and mounted within the cylinder is rotated by a shaft of a driving motor and a belt connected to a pulley formed on a shaft seal of the rotor, and the injected food waste moves to the outer surface of the rotor by the centrifugal force generated by the rotated rotor and permeates between an outer wall of the rotor and an inner wall of the cylinder, and then the food waste is smashed a series of first and second times due to repeated collisions on the inner wall of the cylinder and the outer wall of the rotor; as the firstly and secondarily smashed food waste is injected into a screw groove formed between screw threads which are the grinding means of a circular rotation body mounted on a lower end of the rotor, if said firstly and secondarily smashed food waste is inserted into a plurality of gaps formed between a plurality of protrusions of a circular fixing body mounted on the lower end of the screw threads of the circular rotation body, the firstly and secondarily smashed food waste formed between the screw threads and the square protrusions is ground by the screw threads of the circular rotation body that is rotated with the rotor; and the ground food waste is dropped into the plurality of gaps formed between the protrusions, so that the ground food waste is collected by blades rotated within a waste bin mounted on a lower end of the circular fixing body, and then the collected food waste is discharged to a discharge pipe coupled with the waste bin and is discharged to the septic tank through a septic tank connection pipe. Since the food waste is handled in a pulverized state, it is rarely difficult to process the food waste with the sludge in the septic tank, thereby greatly reducing various disposal stages of the food waste and reducing costs necessary for the disposal stages. Consequently, the invention provides ease of handling food waste.
