The invention discloses a frequency conversion flue-cured tobacco heat pump dual-power barn, which comprises a flue-cured tobacco room, a heating room, a heat pump unit, and a biomass fuel furnace. The return air outlet, the heating room is provided with a diversion wall facing the return air outlet, the heat pump evaporator of the heat pump unit is installed directly opposite the vent, the heat exchange device is installed above the heat pump evaporator, and the diversion fan is installed above the heat exchange device. The heat pump condenser of the heat pump unit is arranged at the air inlet, a biomass fuel furnace and a control device are arranged in the heating room, and a monitoring system connected to the control device is arranged in the flue-cured tobacco room. The present invention realizes automatic control through a control device, can precisely control temperature changes, and has high heat utilization efficiency. Compared with other curing methods, the curing cost is low and energy-saving, and the loss of tobacco leaf curing modulation is reduced, and the yellowing of tobacco leaves is coordinated with color fixing. Drying is matched with aroma, and the goal of roasting tobacco leaves to be yellow, dry and fragrant is achieved.
