FLUIDIZED LAYER DRYING MACHINE AND DRYING METHOD OF WET RAW MATERIAL USING FLUIDIZED BED DRYING MACHINE

摘要

PROBLEM TO BE SOLVED: To prevent clogging due to wet raw material input from a charge chute to a gas dispersing plate of a fluidized layer drying machine.;SOLUTION: In the fluidized bed drying machine 3, the wet raw material is charged from the charge chute 8, high temperature gas is blown from the lower side of the gas dispersing plate 5 as a heat source-cum-fluidizing gas, and a fluidized bed 9 is formed on the gas dispersing plate 5 to dry the wet raw material. A flow velocity of the heat source-cum-fluidizing gas blown in from the lower side of the gas dispersing plate 5 of the immediate below part of the charge chute 8 is provided faster than the flow velocity of the heat source-cum-fluidizing gas blown in from the lower side of the gas dispersing plate 5 other than the immediate below part of the charge chute 8.;COPYRIGHT: (C)2011,JPO&INPIT
