The reason why sticky bean bags collapse when steamed is because of the principle of thermal expansion and cold contraction. Just after steaming, the lid was opened, which led to the rapid entry of cold air outside the pot, and the sticky bean curd suddenly cooled down.

When the bean bag is steamed in the pot, the temperature is very high, and the bean bag is full of hot air, so the bean bag is very bulging. The lid suddenly opened, the cold air outside quickly entered, and the bean bag suddenly became cold. Because heat expands and contracts, it will contract. Don't open the lid after the flameout. Wait two minutes for the temperature in the pot to drop slowly. When the temperature difference between inside and outside is small, it will be much better to open the lid again.

Tip: When steaming sticky bean bags, be sure to steam them in cold water. The steaming time is generally 15 to 20 minutes. The specific time should be adjusted according to the filling situation and the size and quantity of sticky bean bags. 20 minutes is the time to boil the water from the pot!
