“Design Modification and Optimization of Soap Stamping - Tableting Machine:- Alicha, Esidene A

ABSTRACT

The machine comprises an automated soap stamping and tableting module, the operational parameters evaluated were conveying speed, stamping and tableting speed, and time of operation while the tableting efficiency, throughput and specific energy consumption of the machine constitutes the responses or performance parameters. Response surface analysis was employed and the initial linear models developed augmented to quadratic models when it was established using the analysis of variance (ANOVA) and residual plots to estimate the performance of the soap stamping and tableting machine. The developed quadratic models was used to optimize the performance of the soap stamping and tableting machine using the Doptimality approach to establish the optimal factor settings of the soap stamping and tableting machine rounding up to the nearest whole number values are 351rpm, 21rpm, and 55 minutes for the conveying speed, stamping and tableting speed and time of operation respectively. The optimal response at these factor settings was 91.3%, 636kg/hr and 3l.lkJ/kg at an optimality rate of 73%, 99.9% and 100% for the tableting efficiency, throughput and specific energy consumption respectively with an overall D-optimality value of 96%.
