The invention discloses a ginkgo leaf high-temperature kill-out and rapid drying device and method. The device comprises a shell, a heating device, a microwave generator, a PLC control device and a power source device. A feeding cavity, a drying cavity and a device cavity are formed in the shell, the feeding cavity is formed in the lowermost end of the interior of the shell, and the drying cavityis formed in the shell and located in the upper portion of the feeding cavity. The device cavity is formed in the uppermost end of the interior of the shell, the interior of the feeding cavity is provided with a negative draught fan device and a feeding bin, and a discharging outlet is formed in the right end of the feeding cavity. The PLC control device is connected with a used electric appliancedevice, and the power source device is arranged at the lower right end of the feeding cavity and provides a power source for the electric appliance device. The method comprises the steps of feeding;dehumidifying and drying; drying by a draught fan; microwave drying; and discharging. According to the ginkgo leaf high-temperature kill-out and rapid drying device and method, the treatment process is more efficient and safer.
