This document proposes the development of a multi-bean sheller machine. It begins with an introduction to the background and current problems with shelling multiple types of beans: the long production time, high labor costs, and ability to only shell one bean type at a time. It then presents the perceived solution of a multi-bean sheller machine that can shell at least four different bean types. The objectives are then outlined as designing and fabricating a prototype that can test shelling different bean types more efficiently than manual labor. The document provides examples of existing single-bean sheller machines and outlines the proposed scope and limitations of the new multi-bean sheller, such as being able to shell 1-2 kg of mixed beans per
