Abstract

The methodology for the optimization of the drying parameters on solar drying of copra was investigated and studied in this paper. This paper investigates the influence of the process parameters like initial mass, inclination angle and time period on the output parameters such as weight reduction rate and moisture content. This investigation was carried out through taguchi methodology and grey relational analysis. Based on the analysis, optimum levels of parameters were determined and the same to validate through the confirmation test. The confirmation results reveals that, there is considerable improvement in weight reduction rate, moisture content and grey relational grade were improved by 37.36%, 32.28% and 32.94 % respectively. It is observed that the machining performance can be effectively improved with respect to initial parametric setting.
