The air energy heat pump flue-cured tobacco moisture regaining unit comprises a curing barn, a heat exchange chamber is fixedly arranged on one side of the curing barn, and a quick humidifying assembly is arranged at the top of an inner cavity of the heat exchange chamber and comprises a water tank;shielding nets A are fixedly nested in the centers of the two sides of the water tank; an exhaust pipe A is fixedly connected to the center of the side, close to the curing barn, of the water tank, an exhaust pipe B is fixedly connected to the center of the side, away from the curing barn, of the water tank, and the exhaust pipe A and the exhaust pipe B are located on the outer side of the shielding net A. Hot water generated in the working process of the unit is reasonably utilized, meanwhile, the heating resistor and the flow guide fan are matched, the hot water is continuously input into the curing barn to conduct moisture regaining treatment on dried tobacco leaves after being changed into water vapor, the operation time is short while labor losses are reduced, the moisture regaining treatment efficiency is effectively improved, therefore, the placing time of the tobacco leaves in the curing barn is shortened, and the tobacco leaf curing efficiency of the curing barn is improved.
