AIR-COOLING PELLET MANUFACTURING APPARATUS AND AIR-COOLING PELLET MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an air-cooling pellet manufacturing apparatus which can cool a pellet with blower air stably adjusted to target humidity at which dew condensation does not give a harmful effect.;SOLUTION: An air-cooling pellet manufacturing apparatus comprises: a blower 1 which generates blower air; a blower air transport pipeline 2 whose one end is connected to the blower 1; a mist supply device 3 which has a mist supply part provided in the blower air transport pipeline 2 and supplies water at a mist amount adjustable from the mist supply part; a pellet cooling part 7 which is connected to the other end side of the blower air transport pipeline 2 and to which a pellet before cooling processing is supplied; a humidity detection part 12 which detects relative humidity of the blower air in a region closer to the pellet cooling part 7 side than the mist supply part in the blower air transport pipeline 2; and a mist supply control part 20 which adjusts the mist amount in the mist supply part in accordance with the relative humidity detected by the humidity detection part 12.;COPYRIGHT: (C)2015,JPO&INPIT
