Put the grain into the bulking machine. With the heating and pressurization, the moisture in the grain is overheated and the grain itself becomes soft. When it reaches a certain high pressure, open the lid of the expander, and the high pressure will soon become normal pressure. At this time, the overheated water in the grain suddenly vaporizes and explodes violently, and the water molecules can expand by about 2000 times. The huge expansion pressure not only destroys the external morphology of particles, but also destroys the internal molecular structure of particles.
