1. Oven drying method, use a large box to soak fresh osmanthus in mineral water (half a pound of fresh osmanthus). Take out the sweet-scented osmanthus and rinse it with mineral water several times to control the moisture, and manually sort out the dead flowers, peduncles, etc. Put it in the oven to dry, take it out and let it cool.

2. Using the microwave drying method, remove the dead flowers and pedicels from the fresh osmanthus, wash them with clean water to control the moisture. Find a piece of clean gauze, pour the osmanthus on the gauze, and prepare to bake it in the microwave. Bake it twice in the microwave on medium heat, the first time is 3 minutes. After cooling, bake it the second time on medium heat, the time is 2 minutes. This kind of dried sweet-scented osmanthus has the best color, and is just right for old and tender ones.

3. Use the quicklime drying method to remove impurities from the picked fresh osmanthus, but do not wash the osmanthus with water. If you have to wash it before you feel relieved, you can rinse the fresh osmanthus with a flower sprinkler, and then use a hair dryer to dry it after purifying the water. Never put the osmanthus to dry in the sun.
