Hot Air Puffing Machine

Popcorn is made by putting corn, shortening, and sugar into a popcorn machine. The production process involves taking an appropriate amount of corn and putting it into a popcorn pot, then placing the popcorn pot on the stove and continuously rotating it to heat it evenly. Then you can burst delicious popcorn.During the heating process, the temperature inside the pot continues to rise, and the pressure of the gas inside the pot also increases accordingly. When the temperature rises to a certain level, most of the moisture inside the rice grains will turn into water vapor. Due to high temperature, the pressure of water vapor is very high, causing the softened rice grains to expand. When the pressure inside the pot rises to 4-5 atmospheres, the top cover of the popcorn pot suddenly opens, and the gas inside the pot rapidly expands. The rapid decrease in pressure leads to an increase in the pressure difference between the inside and outside of the rice grains, resulting in a rapid expansion of high-pressure water vapor inside the rice grains. The rice grains immediately burst and turned into popcorn.
