Design and Fabrication of Cashew Nut De-Shelling Machine

This research project is about designing a cashew nut sheller intended to semi-automatically process the sun-dried cashew nuts of our benefactor in Bataan. The first part of this research covers numerous information about the cashew nut production, cashew nut specification, pre-treatment methods, transversal cutting of cashew nuts. The researchers then classified the hazards in manual cashew nut shelling, which led to the development of the scheme to be used in this study. The concepts were applied for the assembly of a machine that can do most of the shelling process. Data gathering through queries, series of trials, and a survey were completed in order to evaluate the different aspects of the cashew nut sheller, the optimal working placement of the blades, length of the v-guide, and the efficiency of the cutting. The performance of the machine was evaluated using the quantitative and qualitative data collected from both testing and survey respectively.
