During the air flow process, the vertical fan and the powerful fan cooperate to ensure the smoothness of air flow. The automatic tea-frying device can drive the rotating rod to rotate when the rotating motor of the frying assembly is driven, so that the stirring blade, the frying plate and the rubber shovel plate rotate. The rotation of the inclined rubber shovel plate, combined with the blowing of air, can better scoop up and turn the tea leaves.
