Yield and Particle Morphology of Spray Dried Salts: Fractional Factorial Design

摘要

The yield of the spray drier has been correlated with the various system parameters namely inlet temperature, aspirator speed, feed flow rate, salt-concentration, atomization rate and molecular weight of salt on the basis of dimensional analysis approach. Attempt has also been taken to design the experiments by Fractional Factorial Design method for both cases i.e. for the blank solution (water) and for the salt solution. The results thus obtained through these developed correlations (by Dimensional Analysis and Fractional Factorial Design) have been validated with the results obtained by ANN-approach and finally the findings obtained from all the approaches have been compared with the experimentally observed values. Attempt was also made to study the particle morphology through the Scanning Electron Microscope.
