Development and performance evaluation of portable liquid soap making machine for small and medium scale industry

The project work entails design, fabrication and testing of a 15 litres semi-automatic liquid soap making machine for small and medium scale industry using cold process method. A survey carried out on conventional method (the local method) showed that the conventional method consumes time, energy, has low output and efficiency and is hazardous to health. The fabricated machine consists of four major components which are gear mechanism, four cylindrical chambers, agitators (impellers) and an electric motor. After evaluating its performance, the machine produced had a mixing and time efficiency of 93% and 92.2% respectively as compared to the conventional method which had a mixing and time efficiency of 81.7% and 36.7% respectively. Results obtained from the performance evaluation indicated that the machine saves time and energy, reduces material wastage, reduces hazards and hence; is far more efficient than the conventional method.Keywords: Fabrication, performance, liquid soap, machine, conventional method, efficienc
