How Puffed Rice Candy is Made

The material of Mixiang is rice, which is put into a pressure furnace and heated by a rolling pressure furnace. During the heating process, the water in the rice grains is heated in the pressure cooker, but the volume cannot be increased. When the pressure furnace is opened, the pressure in the furnace is suddenly released, the water in the rice grains instantly turns into gas, and the internal high-pressure gas is too late to release, so the explosion produces an explosion sound.
