Infrared drying technology is widely used due to its fast drying rate and low energy consumption. Graphene has a high electrothermal conversion rate and can be used as a new heat source for far-infrared drying equipment, improving drying efficiency and reducing energy consumption. This study aims to investigate the drying kinetics of graphene far-infrared paddy drying equipment, as well as the optimal combination of distances between radiations, drying temperature, drying time, air volume, etc. The experimental results show that the best effect is achieved when the irradiation temperature is 60 ℃,, the radiation distance was 30 mm, the grain flow rate was 7 kg/min, and the air velocity in the dehumidification section was 8.5 m/s. By analyzing the dynamics and energy of the drying process, a basis is provided for formulating drying strategies to achieve the development of new drying machinery. This study is of great significance in promoting the level of mechanized grain drying, promoting high yield and harvest, and ensuring food security.
