Hot air circulation and self-dedusting type sterilizing device for fresh eggs

The utility model relates to a fresh eggshell surface wind-heat sterilizing device with hot air circulation and self-dedusting functions and belongs to the technical field of common equipment for egg cleaning. The wind-heat sterilizing device is capable of effectively separating chicken feathers, excrement, dust and other impurities in a circulation air duct and discharging the impurities out of the circulation air duct to keep the air duct clean and unobstructed. The device is characterized in that an axial-flow fan is adopted in a high-temperature wind-heat sterilizing area for air supply, a straight tube type electric heating radiant tube is adopted for providing heat, a temperature sensor acquires temperature data in real time and transmits the temperature data to an PLC, an air deflector adjusts the air direction and air quantity, and repeated and circulated utilization of clean hot air in the air duct is achieved with the assistance of devices including a high-temperature-resisting heat insulation circulation air duct, a cyclone dust collector and an air return pump. An air supply port of a natural air cooling area is arranged at the tail end of a fresh egg conveying chain to conduct countercurrent blowing on eggs to be cooled, so that hot air carrying the heat of eggs is sent to an air supply port of the high-temperature wind-head sterilizing area while the eggs are cooled, and energy-saving hot air supplement is realized.
