Influence of drying chamber, energy consumption, and quality characterization of corn with graphene far infrared dryer

This study used a graphene far infrared dryer to experimentally evaluate the two varieties of corn (ZD88 and RP909) at three varying temperatures (35, 45, and 55 degrees C) to analyze the drying process. The experimental finding showed that ZD88 observed a minimum energy consumption of 2.93 kWh at 55 degrees C. The ZD88 at 35 degrees C did not show any effect on the structure on the surface of the corn grains with a higher RC of 43.85%. The RP909 showed the starch granules formed an amorphous granular structure on the surface with a lower RC of 37.45% at 55 degrees C. The color parameter values showed an L* and b* decrease, while the a* values increased. ZD88 and RP909 observed an A-type peak pattern crystal structure. Therefore, this innovative graphene far infrared drying system could be a promising solution to enhance food industrial applications and improve corn characteristics.
