▎ 摘　　要

NOVELTY - Grain circulation dryer based on graphene far-infrared heating, comprises grain storage components arranged above first far-infrared heating component from top to bottom along the height direction. A grain material in the collecting hopper is conveyed to the top of the lift through a screw conveyor and a hoist, and then the grain flow direction controller is used to adjust whether the grain material enters the discharge pipe and is discharged from the dryer or enters the grain storage component to be dried again. A far-infrared heating assembly includes a first outer wall heat preservation plate and multiple graphene far-infrared radiation plates. The ventilating and dehumidifying assembly includes a centrifugal fan and multiple air ducts arranged vertically at intervals. Each air duct is provided with a number of ventilation holes, and a number of second vertical passages are formed between each duct, and grain materials fall into the second vertical passage. USE - Used as grain circulation dryer based on graphene far-infrared heating. ADVANTAGE - The dryer emits infrared rays at a low temperature after being energized, adjusts the surface temperature of the emission source precisely at 40-80degrees Celsius, improves the drying quality and efficiency, and reduces the production cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for grain circulation drying method based on graphene far infrared heating.
