The temperature and pressure in the rice popsicle furnace increase, and the water in the rice grains becomes soft under the high temperature.
After the iron furnace is turned on, the pressure drops instantly, forming a huge pressure difference between the inside and outside of the rice grains. Because the skin of the rice grains is relatively dense, the rice grains expand violently and become popcorn.
Many inventions follow this principle, such as removing the hard shells of pine nuts, peeling sunflower seeds, and even decomposing artificial diamonds along the cracks invisible to the naked eye, cleaning filters that cannot be disassembled, Crystal sugar turns into powder etc. According to statistics, there are more than 200 invention patents completed in this way in different fields and at different times.
