The invention discloses duck egg washing, screening and air-drying equipment and relates to the technical field of agricultural product processing. The duck egg washing, screening and air-drying equipment comprises a control box, a rack, a washing device, a screening device and an air-drying device. The washing device comprises a first spiral conveying mechanism, a high-pressure water inflow pipe, a water storage tank and a booster pump; a feeding port is formed in one end of the first spiral conveying mechanism; water spray pipes connected with the high-pressure water inflow pipe are evenly distributed on a shell of the first spiral conveying mechanism; a water drainage pipe at the lower portion of the first spiral conveying mechanism is connected with the sewage side of the water storage tank; clean water of the clean water side of the water storage tank is conveyed to the high-pressure water inflow pipe through the booster pump; and a filter screen is arranged between the sewage side and the clean water side of the water storage tank in a spaced manner. The screening device comprises a lattice rotary disc and a baffle which are arranged below an outlet of the first spiral conveying mechanism and on one side of the first spiral conveying mechanism respectively, and a collection basket is arranged below the lattice rotary disc. The air-drying device comprises a second spiral conveying mechanism and an air feeding pipe, air nozzles connected with the air feeding pipe are evenly distributed on a shell of the second spiral conveying mechanism, and an outlet of the second spiral conveying mechanism is connected with a conveyor belt. By the adoption of the duck egg washing, screening and air-drying equipment, work efficiency is improved, and labor intensity is relieved.
