Document Type and Number:
Japanese Patent JP3581729
Kind Code:
B2
Abstract:
A fluidized bed equipment for drying or cooling of powder according to the present invention comprises an air dispersing floor plate (2) having numerous openings (22) for dispersion of fluidizing air, a fluidizing air chamber (3) below the air dispersing floor plate, a fluidizing chamber (4) for powder above the air dispersing floor plate, and a heat transfer unit (11) composed of a plurality of rectangular heat transfer metal plates (10) disposed vertically and in parallel on the upper side of the air dispersing floor plate (2), said metal plate being provided internally with horizontal passage (5) having inlet pipe (8) and outlet pipe (9) for a heat transfer medium at each end. Ultra fine or ultra low density powder can be dried or cooled with an extremely high heat efficiency, especially even a fine powder having the maximum areal air velocity of not higher than 20cm/s which is recognized as impossible for being processed by conventional fluidized bed drying or cooling equipments can be treated efficiently.
