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

7. General Objectives
This study aims to develop a prototype that unshell four
different type of beans.
Specifically, this study aims to:
1. Design a prototype multi-bean sheller.
2. Fabricate the prototype , as designed with the following
parts:
a) 1-hp dc motor
b) Belt and pulley e) chassis
c) blower f) Rotating Sheller
d) Collector basin g) Shaft h)sieving screen
Objectives of the Study
8. 1. To fabricate as design
2 To test the capability of the machine to shell the different types
of beans.
3. To improve the production time.
4. To evaluate the aesthetics, and the efficiency of the
machine.
Objectives of the Study
9. Scope and Limitations
• The machine could handle 1-2 kilograms of beans per
batch.
• The machine uses a 1-hp dc motor, 10 inches diameter and
20 inches length of the screen frame.
• Easy to operate.
• It is a one man operated machine.
• Must be mounted on a flat surface.
• The subjected product is dry.
• Can shell different sizes of bean at the same time.
