The present invention discloses a preparation method of dry bird's nests. The method successively comprises the following steps: S1, 20%-50% of fresh water is absorbed by a method of soaking or multiple spraying; S2, a nutrient preparation at 40-50 DEG C is given to the bird's nests by a soaking or spraying method; S3, the bird's nests are kept in a closed environment with a high humidity at a relative humidity of 90% or more without being soaked in water, an environment temperature is maintained at 40-55 DEG C and an operating time is 20-40 min; S4, impurities in the bird's nests are removed and washed clean; S5, the washed clean bird's nests are put at 10-20 DEG C and under a device environment at a relative humidity of 70%-85%; S6, the bird's nests are changed to be put under the device environment at a relative humidity of 30%-50%; and S7, the S5 is repeated until the drying is completed. The dry bird's nests prepared by the preparation method are clean and free from impurities and have a puffing effect with a higher multiplying power due to stable bird's nest colloids.
