    Abstract: A hulling apparatus that can improve hulling efficiency and hulling roll durability. A first air nozzle and a second air nozzle to cool surfaces of hulling rolls by blowing compressed air thereto are provided at a vicinity of the hulling rolls of the hulling apparatus. Consequently, a hardness of a rubber layer at the surfaces of the hulling rolls can be prevented from being lowered. Thus, hulling efficiency and hulling roll durability can be improved.
