Popcorn is a puffed food made from corn, ghee and sugar. It tastes sweeter. First discovered in the Inca Empire, popcorn is one of the oldest snacks in the world. Become a food that children and young people like to eat.

The principle of popcorn.

During the heating process, the temperature in the container increases continuously, and the gas pressure in the container also increases continuously. When the temperature rises to a certain level, the rice grains will gradually soften, and most of the moisture in the rice grains will turn into water vapor.

Due to the high temperature, the pressure of the water vapor is great, causing the softened rice grains to expand.

As the temperature increases and the pressure increases, when the pressure is 9 times higher than atmospheric pressure, the corn husk will burst, and then the starch and steam inside will burst as the inner and outer pressures tend to balance.

In this way, popcorn is produced.
