DESIGN OF A SMALL-SCALE STARCH PROCESSING PLANT
This study presents the design, fabrication, and performance evaluation of a small-scale starch processing plant using cassava as feedstock. The research was motivated by Nigeria�s heavy reliance on imported starch despite abundant local cassava production and the high cost of existing industrial equipment. The plant was designed to integrate key processing stages including cleaning and peeling, grating, sieving, sedimentation, drying, and milling. Standard engineering design principles were applied in selecting appropriate materials and components, with an emphasis on durability, affordability, and local availability. A cassava grating machine was fabricated as a pilot unit, powered by a 2.0 Hp electric motor and constructed using stainless steel for food-contact parts and mild steel for the frame. Performance tests indicated an average throughput capacity of 280 kg/hr, with an overall efficiency of 91%. Comparative cost analysis showed the fabricated machine to be over 30% cheaper than imported alternatives of similar capacity. The findings demonstrate that small-scale, locally fabricated starch processing equipment can provide an effective solution to Nigeria�s starch production gap, reducing import dependence and promoting industrial self-reliance. It is recommended that future work focuses on automation of the processing line and integration of multiple operations under a single power source to further improve efficiency and scalability.
