OPTIMIZATION OF LEATHER DRYING PROCESS

摘要

In this paper, a mathematical model of synthetic leather drying for removing the organicsolvent is proposed. The model proposed adequately describes the real processes. Toimprove the accuracy of calculated moisture distributions a velocity correction factor(VCF) introduced into the calculations. The VCF reflects the fact that some of the airflowing through the bed does not participate very effectively in drying, since it ischannelled into low-density areas of the inhomogeneous bed. The present paperdiscusses the results of experiments to test the deductions that increased rates of dryingand better agreement between predicted and experimental moisture distributions in thedrying bed can be obtained by using higher air velocities.
