Discussion with Reviewers Revjewer I: Why have you not used the following , easier 215way to calculate Umr? I) Determine the sphericity,¢, from geometric considerations; 2) calculate Em1 from Equation 6;and 3) directly solve equation for Um1 noting that t.P/L~(lE:mr)(pp-p)g and that one of the roots of the quad ratic is negative and therefore unrealistic. AY..!b.2.r§: Our method is an alternative to the one described above which assumes that the bed is compactly packed. However at Umr compactness is lost, as a result of this we believe our method to be more accurate. H. Arastoooour: The technique of ci rculating fluidized bedshas not been examined in great depth. A significant amountof work has also been done in fluid ized beds including jet,with or without draft tube.Authors: We have looked at the literature concerningci rculating fluidi sed beds and the use of jets in fluidizedbeds. It was felt that while these techniques have greatpo ten tial in chemical processing, they have limitedapplications in food processing industries.
