Generally, the bird's nest should be soaked for about 2 hours.

1. Bird's Nest with Different Yan Ages

Bird's Nest with Different Yan Ages has different foaming time. In the nest built by new Yan, Yan Zhan Yan Si is thin, and its body thickness is relatively thin, so it absorbs water quickly and foams quickly, and it can be soaked in cold water for 2 hours. The old swallowtail is big, the swallowtail is thick, and the overall thickness of the swallowtail is more than 1 cm. This kind of bird's nest will take longer to foam, and the cold water will take about 3 hours.

2. Different plucking processes

Generally speaking, the time for soaking the bird's nest with dry plucking/semi-dry plucking process is 2 hours, and the bird's nest with wet plucking can be soaked in about 1 hour.

3. Different parts of the bird's nest

The timid swallows are thin, which can be completely soaked in 1-2 hours. The size of the broken swallow is very small, and it can be soaked in 1-2 hours. The swallow's horn plays the role of fixing the bird's nest, so the texture is harder, and the corresponding soaking time will be longer, about 3 hours, so the swallow's horn should be torn halfway when the whole bird's nest is soaked.

the method of soaking the bird's nest

1. boiling water: also known as soaking, boiling and stewing (it is considered to be used only in emergency).

The bird's nest granules are soaked in boiling water, and the soaking rate of water is developed by raising the temperature and heating, so as to promote the bird's nest granules to fully expand, so as to achieve the effect that it cannot be reached by rising water at normal temperature.

when making bird's nest, the water and articles that have swelled the bird's nest should be cleaned to avoid oil stains, otherwise it will endanger the quality of hair making. The foaming rate is the key parameter to consider the quality of bird's nest. The foaming rate is also the most essential feature to consider the quality of bird's nest.

2, cold water hair: also known as soaking hair, bleaching hair (or warm water hair), the temperature is generally around 3℃, at normal temperature in summer and warm water in winter.

soak the bird's nest in cold water (considered as mineral water) for two hours, pick it up and remove the fluff and residue, then change the water in the fish tank and soak it continuously. At this time, pull the bird's nest a little, especially the bird's nest, and soak it continuously for 6-8 hours until it is swollen and malleable.
