The invention relates to the technical field of environmental protection, in particular to kitchen garbage cleaning equipment. The kitchen garbage cleaning equipment comprises a garbage collecting tower, a centrifugal dehydrating device, a sorting table, a garbage raking machine, a rotary-cutting crusher, a tunnel drying machine, a winnowing device, a vibratory separating and screening device, a rack, a conveying belt, a hoister, a cleaning device, a garbage shoveling and conveying device and power equipment. Kitchen garbage is minced and broken in a garbage collecting tower to remove water byextrusion, after centrifugal dehydrating is carried out, large packing objects and the like are sorted through intelligent equipment, and strip-shaped thin-film plastic packing objects and residual packing ropes are sorted out by the garbage raking machine; then secondary mincing and breakage and hot-air drying are carried out until the garbage is loose; then small packing objects and light plastics and foams are removed by winnowing; and finally, light plastic blocks and heavy objects such as glass, metal and bricks are separated by a vibrating sieve, available kitchen garbage is obtained, the circumstances that harmful garbage such as plastic packing objects enter a kitchen garbage recycling system again are reduced effectively, and ecological benefit and economic benefit of utilizationof the kitchen garbage are increased.
