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 °C) to analyze the drying process. The experimental finding showed that ZD88 observed a minimum energy consumption of 2.93 kWh at 55 °C. The ZD88 at 35 °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 °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.
