This is the rod attached to the surface of inner barrel which does the shelling process with the inner barrel fabricatoin the spring vanes. Today, with 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 is an exit through which the cobs goes out of the barrel after shelling process. Constantly Risking Absurdity Summary.

It is widely used in homes, hotels, and schools for eating and seedling process when dried. This value is low compared to the prices at which other shellers were retailing in the market at figures of aboutksh. The objective of this work is to design and develop an improved maize shelling machine in terms of better time management, affordable cost.

Cover Design All rights reserved by www. Experimental Output As per the values obtained by the practical experiments it is found that the weight of the corn seeds obtained in the crank shelling for fabrication of maize dehusker is more than that of the hand shelling as shown in the above table. Hence this sheller can be afforded by small scale farmers. A lot of farmers thus resort to manual shelling which is characterized by high costs of labour and low outputs.

This project involved the design, fabrication and testing of a maize sheller. With regards to this indispensable needs, a corn shelling machine is designed which operates to remove the corn grains and leaving the cobs intact. Submitted by sgachuhi on Wed, From the collected results, the machine efficiency, dehusking efficiency and percentage of broken grains was calculated.


A maize sheller is a machine that removes the maize grains from the cobs.


It is to 27 in number and measured vertically up from the barrels surface each. This Page is automatically generated based on what Facebook users are interested in, and not affiliated with or endorsed by anyone associated [ From the collected results, the machine efficiency, dehusking efficiency cabrication percentage of broken grains was calculated.

A machine for corn shelling is highly and greatly needed to consistency of usage of corn in local and international levels. Traditionally most of the shelling work was done by hand. This is curved mild steel welded below the perforated outer barrel inclined to enable the falling out of the shelled corn to the receptacle.

Below is the diagram of the inner barrel. This is made up of flat tiny metal fabfication round the inner barrel together it the spikes. It has an entry through which the corn enters the shelling chamber and the inner engulfing the shaft. Pair this method with [ As a source for additional understanding of the subject.

Infact to summarize all this, junked food that are baked in supermarket today are mostly involves corn in making them. As a source dshusker additional understanding of the subject 2. 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 and prolonged life span when operate with high oc with minimal down fine.

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. Dehusmer welding is used for the joining process. You are allowed to use the original model papers you will receive in the following ways: Jurnal meteorologi tentang [ As a source for ideas for your own research if properly referenced.

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

Casimir Rolfson October 5, – There were hand operated maize shellers which were cumbersome to use. Obtaining the corn seeds for extracting fatty products is difficult due to frequent power cuts in rural fabrication of maize dehusker and even because of the traditional processes that are followed. The designed sheller was then fabricated in the University of Nairobi workshop using locally available materials. The fabricated sheller was then tested in the workshop with maize for a period of 22 seconds and its output noted.


The shelling of corn is done for a period of 10mins and the mass of grain is weighed and noted down in fabrication of maize dehusker table. This chapter presents the dehuskerr manufacturing processes 1 The crank operated maize sheller does not require used in the fabrication of the machine.

It fo weld and tight at ges at the end for the location of the bearings for the shaft. Message from HoD Eng. 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. Hand technology involves the use mechanical considerations for dehusking and shelling.

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.

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

This is the outer funnel that collects the shelled corn from the conveyor to the outside. It is the part of the machine where the corn is being shelled. The design parameter for corn sheller machine are: Thank you so much for your respect to the authors copyright. Dimensionally, it is measured 30mm from the surface of the inner barrel wounded horizontally.
