The present invention discloses a processing technology of preserved meat, belonging to the technical field of food processing. The processing technology of the preserved meat comprises the followingsteps: step one, raw material processing is conducted; step two, pickling is conducted; step three, washing is conducted; and step four, smoking is conducted; during the smoking, a smoking device is used; the smoking device comprises a combustion chamber, a smoking chamber and two water pumps; a smoke inlet pipeline is arranged for communication of the combustion chamber and the smoking chamber; the outside of the smoke inlet pipeline externally sleeves with two heat exchange mechanisms; each heat exchange mechanism comprises a sleeve cylinder, a water inlet pipe and a water outlet pipe; the water inlet pipe and the water outlet pipe both communicate with the sleeve cylinder; the water outlet pipe communicates with the water pump; the heat exchange mechanisms comprise the first heat exchange mechanism and the second heat exchange mechanism arranged successively from left to right; activated carbon is arranged in the smoke inlet pipeline between the first heat exchange mechanism and second heat exchange mechanism; fuel is placed in the combustion chamber to be ignited; and then drained pork is placed in the smoking chamber to be smoked for 7-10 d; and step five, fermenting is conducted. The scheme can effectively reduce benzopyrene on the surface of the preserved meat.
