Drying of a Dilute Suspension in a Revolving Flow Fluidized Bed of Inert Particles

摘要: Abstract Revolving air flow was generated by oblique holes on distribution board in a fluidized bed dryer. Such revolving shows large scale velocity fluctuation radial as well tangential directions. This turbulent of can fluidize the inert particles with superior performance than vibrated bed. The is simpler fabrication and easier operation. For two types tested, 4 mm glass beads 4 mm × 5 mm Teflon cylindrical extrudates, volumetric heat transfer coefficients were found to increase liquid feed flowrate but decrease inlet temperature, height static bed, concentration. gives an coefficient 1 kW/m3 K, represents 15–25% enhancement from ordinary operated at 60 mm, diameter 140 mm, superficial 3.5 m/s, (Soya milk) ...
