Project and Seminar Material for Mechanical Engineering ME


A machine for corn Sheller is highly and greatly needed for consistence of usage of corn in local and international levels.

With regards to this indispensable need, a corn-shelling machine is designed which operates to remove the corn grains and leaving the cobs intact.

In attainment to this design objective and aims, a proper considerations was given to the machinability factor which includes, installation, simplication, durability, choice material operational efficiently serviceability of the masculine low costing and prolonged life span when operates with utilization with minimal down fine

The design details are given includes such items as materials and their characteristics. Adaptation methodology the parts relation with the whole device and the effect of the finished product upon which an inquisitive mind can make collection of fact in future which related to this project.

Chapter One


We have participated indeed in mass shelling of corn using the most primitive. Cumbersome and difficult method of hand shelling, which encourages time consuming, and human stressfulness. Corn otherwise known as “Oka” in Igbo tribe is mostly used seed across all the tribe in country today. It is widely used in homes, hotels and schools for eating and seeding process (when dried). It is therefore hardly to see any Nigerian who has not tested it in one way or the other.

Now, since it is very imperative for dieting inclusively, it can be refined to form varieties of food supplementary diet such as making of Akamu (pap), semuviter corn powder, corn mill etc.

Today, in our industrial sectors such as ceramics and biscuit industry, it is widely used for making of biscuit, flouring for baking of bread, and corn Mill. Infect to summers all these, junked food that are baked in supermarket today are mostly involves corn in making them.

In the light of this as technology advances forward, on introduction of this machine (Sheller) made manifest and come into existence which is more stressless, easy to operate, low costing and time reduction with high degree of production volume and efficiency modifications have also been made it possible to be manually and electro – mechanical operated types depending on the choice of design and the speed of shaft required

Today, with the aid of this, it has created availability of corn Sheller (steeling machine) even in the market which indeed removed our difficulties and impossibilities when using and engaging with the modern method of design.

1.1 Purpose Of Construction

This project is meant to achieve the following purpose

  1. To design and fabricate corn sheller which easy to operate with high degree of efficiency
  2. To design and fabricate a machine (corn Sheller) that would save time and cost, with high degree of production volume.
  3. To design and construct a corn Sheller that would not have much breaking effect of grains, leaving the cob’s intact during the process.
  4. To design and constrict a corn Sheller that is economical and have little or no complication in maintenance
  5. To design and construct a corn Sheller with high percentage at local technology
  6. To design and construct a machine that is cost effective and manual stress reduction

1.2 Importance And Specification Of The Project

The importance attached to this design is the facilitation and the production of voluminous corn Sheller without much time and without recounting much breakage of the grains of the corn in shortest possible time

The specification was obtained considering the items or component used and the hopper and barrel dimensions put into consideration as well.

The sign parameter for corn Sheller machine are.
