Task Calculation of the drying apparatus

Task Calculation of the drying apparatus

G kg / h of grain is dried in a fluidized bed dryer. L kg/h of air with a temperature of 60 °C is consumed for drying ( = 1 kg/m3; = 21.1×10-6 Pa×s). Determine the boundaries of the existence of a fluidized bed Wps and Wun, the number of fluidization KW and select the main dimensions of the device D and Nap. The particles have a spherical shape. Drying time τ = 1 h.
Grain: buckwheat, G = 221kg/h, L = 14550 kg/h, 1.22 g / cm3; Particle diameter
dh = 4.5-5.5 mm
