Ergonomics in developing hand operated maize dehusker-sheller for farm women.

A machine for corn shelling is highly and greatly needed to consistency of usage of corn in local and international levels. With regards to this indispensable needs, 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, simplification, durability, choice material, machine, low costing miaze prolonged life span when operate with high utilization with minimal down fine.

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

Determination of Driving Power.

We have participated indeed in mass shelling of corn using the most primitive, cumbersome, and difficult method of hand shelling which encourages rime consuming and human stressfulness.

It is widely used in homes, hotels, and schools for eating and seedling process when dried. It is therefore very rare 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 papSemovita corn pounded, corn mill etc. Today, in our industrial sectors such as ceramics and biscuit industry, it is widely used for making of biscuit, flouring for bakery of the bread, and corn mill.


Infact to summarize all this, junked food that are baked in supermarket today are mostly involves corn in making them. In the light of this as technology advance forward, an introduction of this machine sheller made manifest and come into existence which is more stressless, easy to operate, low costing, and deehusker reduction with high degree of production volume and dehusket.

Modifications have also made it possible to be manually and electro-mechanical operated type depending on the choice of design and the speed of shaft required. Today, dehsker the aid of this, it has created availability of corn sheller shelling machine even in the market which indeed removes our difficulties and impossibilities when using and engaging with modern method of design.

This project is meant to achieve the following purposes. The importance attached to this design is the facilitation and the production of voluminous corn shelling without much time and without encountering 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 design parameter for corn sheller fabrixation are:. It is a half of glindrical shaped perforated below to enable shelled corn to rush out to the conveyor to the outlet basin.

Dehuxker is weld and tight at ges at the end for the location of the bearings for the shaft. At the lower end of one is an open segments serving as outlet for the cobs and a hood is built covering it.

Below is a complete drawing of the outer barrel shown. Diameter of inner barrel is and its length is and consequently the diameter of the shaft and having a length of. Below is the diagram of the inner barrel. This is similar to a port but the difference is that it is bigger and not covered like the port. It is eight rapezoid or rectangular in shape, each shape chose have its advantage and disadvantages.

It has an entry dhusker which the corn enters the shelling chamber and the inner engulfing the shaft. The diagram is shown below. This is the outer funnel that collects the shelled corn from the conveyor to the outside.



This is the rod attached to the surface of inner barrel which does the shelling process with the inner barrel and the spring vanes. It is to 27 in number and measured vertically up from the barrels surface each.

This is an exit through which the cobs goes out of the barrel after shelling process. These are the holes perforated below the outer barrel through which the shelled grain corn falls out to the conveyor.

This is curved mild steel welded below the perforated outer barrel inclined to enable the falling out of the shelled corn to the receptacle. This is made up of flat tiny metal welded round the inner barrel together it the spikes.


It is the part of the machine where the corn is being shelled. Dimensionally, it is measured 30mm from the surface of the inner barrel wounded horizontally.
