The layered circulating air-curing machine comprises a rack; a gear motor assembly, a tobacco taking frame assembly, a top-layer track, a tobacco falling frame assembly, a tobacco feeding trolley and a ground track arranged on the rack; a circulating unit frame located in the rack; an air-curing circulating unit located in the circulating unit frame; and an electrical controller used for realizing automatic operation control; the gear motor assembly, the air-curing circulating unit, the tobacco taking frame assembly, the tobacco feeding trolley and the tobacco falling frame assembly are electrically connected with the electrical controller respectively; the gear motor assembly is installed at one end of the rack; and a plurality of air-curing circulating units are mounted in the circulating unit frame in a layered manner. The air-curing circulating units independently perform ferris wheel type operation and ascend layer by layer in the circulating unit frame for air-curing till the top layer is reached, and the air-curing requirement is met. According to the invention, ventilation among the tobacco leaves is guaranteed, the quality of the aired cigar tobacco leaves is good, and the working efficiency is improved.
