The invention discloses a feeding sensing system of kitchen waste separation equipment and the separation equipment. The feeding sensing system comprises a photoelectric sensor, a screw conveyor, a U-shaped grating groove for accommodating the screw conveyor, a casing for accommodating the U-shaped grating groove as well as a feeding basin opening formed in the top of the casing, wherein inclined plates are arranged on the periphery of the feeding basin opening, the higher end of each inclined plate is connected with the casing, and the lower end of the inclined plate is connected with the top of the side wall of the U-shaped grating groove; the side wall of the U-shaped grating groove is a vertical wall parallel to a rotating shaft of the screw conveyor; the photoelectric sensor is mounted on the casing and can emit optoelectronic signals into the U-shaped grating groove through grating holes in the side wall of the U-shaped grating groove. The key point of the feeding sensing system is that by means of the special mounting position of the photoelectric sensor, the problem about validity of correlation between sensor signals and kitchen waste accumulating actions is solved, and the condition of failure of signal actions due to splashing pollution of the kitchen waste and sensor covering with residues is avoided. The invention further discloses the kitchen waste separation equipment provided with the feeding sensing system.
