The quest for a drudge-free and sustainable technology that will be acceptable by the small and medium scale groundnut oil processors motivated the current study. An existing groundnut roasting, de-skinning, winnowing and kneading machines were modified by re-designing the various components involved and a suitable milling machine was also extensively designed and constructed. Detail drawing of the modified existing machines and developed milling machine were carried out using pro E engineering drawing software before constructing the machines. The constructed unit machines were assembled to form an integrated machine and the performance of the machine reported by previous studies reveals reduced drudgery involved in the groundnut extraction process. More so, the entire cost incurred in the construction of the machine (N173, 543.50), the extraction efficiency and yield recorded reveals that the developed machine has suggested a sustainable technology for the small and medium scale groundnut oil processors.
