Embodiment 1
[0030] (1) Select plump, green and slightly yellow fresh yellow flower buds that are harvested within 4 hours, remove the flower stalks of the day lily, and rinse them with running water.
[0031] (2) Drain the rinsed day lily with a vibrating dehydration sieve until there is no water dripping, and spread it evenly on a special microwave tray with a thickness of 4cm, and cover it with a layer of insulating cloth.
[0032] (3) Push the material tray into the 2450MHz microwave heating equipment to de-enzyme the daylily. The de-enzyme conditions are: microwave heating power 20kW, microwave action time 80s, and then use a centrifugal blower with a wind speed of 3m / s to cool down to room temperature .
[0033] (4) Push the daylily that has been heated by microwave and cooled to normal temperature into 2450MHz microwave drying and dehydration equipment for a dehydration treatment. A centrifugal blower with a wind speed of 3m / s is used to cool down to room temperature.

Embodiment 3
[0046] (1) Select plump, green and slightly yellow fresh yellow flower buds that are harvested within 4 hours, remove the flower stalks of the day lily, and rinse them with running water.
[0047] (2) Drain the rinsed day lily with a vibrating dehydration sieve until there is no water dripping, and spread it evenly on a special microwave tray with a thickness of 4.5 cm, and cover it with a layer of insulating cloth.
[0048] (3) Push the material tray into the 2450MHz microwave heating equipment to de-enzyme the daylily. The de-enzyme conditions are: microwave heating power 20kW, microwave action time 90s, and then use a centrifugal blower with a wind speed of 4m / s to cool down to room temperature .
[0049] (4) Push the daylily that has been heated by microwave and cooled to normal temperature into 2450MHz microwave drying and dehydration equipment for one dehydration treatment. A centrifugal blower with a wind speed of 4m / s is used to cool down to room temperature.
