PROBLEM TO BE SOLVED: To feed a dried/heated powder to a required powder receiving device while certainly preventing reduction of its temperature. SOLUTION: The bucket elevator 1 is provided with a casing 2 vertically installed while providing a material throwing port 4 on a lower casing 2a and providing a chute 5 on an upper casing 2c; and a plurality of buckets mounted to a chain laid on sprockets arranged at an upper part of the upper casing 2c and a lower part of the lower casing 2a in the casing 2 and circulated/moved in a vertical direction. Electric heaters H1, H3, H4 are mounted to an outer periphery of the lower casing 2a of the casing 2 and a lower surface 5a of the chute 5. Reduction of the temperature of the powder in the bucket upwardly conveyed is prevented by heating of air in the casing 2 by the electric heaters H1, H3, H4. COPYRIGHT: (C)2007,JPO&INPIT
