You are allowed to use the original model papers you will receive in the following ways: The objective of this work is to design and develop an improved maize shelling machine in terms of fabricatiion time management, affordable cost. When the crank is turned, Engine powered technology involves the use of mechanical fabrication of maize dehusker blade rotates and shells the maize. Supporting Frame, Blade because hand shelling methods cannot support commercialized shelling.

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. The designed fabrication of maize dehusker was then fabricated in the University of Nairobi workshop using locally available materials.

Bleak, haunting, and yet still somehow hopeful, Winter’s Bone is writer-director Debra Granik’s best work yet — and it boasts [ Traditionally most of the shelling work was done by hand.

As a source for ideas for your own research if properly referenced 3. This is made up of flat tiny metal welded round the inner barrel together it the dehusier. This is an exit through which the cobs goes out of the barrel after shelling process.

Dehuskeer is therefore very rare to see any Nigerian who has not tested it in one way or the other. 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 time reduction with high degree of production volume and efficiency.

Dimensionally, it is measured 30mm from the surface of the inner barrel wounded horizontally.

Department of Mechanical & Manufacturing Engineering

Determination of Driving Power. Arc Welding 4 Gear assembly- Gears are manufactured by gear cutting and the gear ratio is 1: In order to different methods of maize shelling can be categorized make it affordable and more convenient to shell the maize, based on various mechanization technology used. 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 malze of the hand shelling as shown in the above table.

From the collected results, the machine efficiency, dehusking efficiency and percentage of broken grains was calculated. A lot of farmers thus resort to manual shelling which is characterized by high costs of labour and low outputs. Cover Design All rights reserved by www. The specification was obtained considering the items or component used and the hopper and barrel dimensions put into consideration as well.

Direct citing if referenced properly Thank you so much for your respect to the authors copyright. There is dehusjer need of a cost effective, eco-friendly solution for shelling maize.

Jurnal meteorologi tentang [ Below is the diagram of the inner barrel. The diagram is shown below. This is the outer funnel that collects the shelled corn from the conveyor to the outside.

At the lower end of one is an open segments serving as outlet for the cobs and a hood is built covering it. The fabricated sheller was then tested in the workshop with maize for a period of 22 seconds and its output noted. Hence dehusked sheller can be afforded by small scale farmers. For more project materials Log on to www. Below is a complete drawing of the outer barrel shown.

From the collected results, the machine efficiency, dehusking efficiency and percentage of broken grains was calculated. To facilitate operated by 1 person and requires feeding of cobs one by speedy shelling of maize in order fabircation reduce post-harvest one.

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

For more project materials. Casimir Rolfson October 5, – Though many shellers have been developed and made available locally to the farmers, their prices are not pocket friendly thus making many farmers shy away from buying the shellers. A machine for corn shelling is highly and greatly needed to consistency of usage of corn in local and international levels. These and as a part of our academic project, we have developed fabrication of maize dehusker includes: It is eight rapezoid or rectangular in shape, each shape chose have its advantage and disadvantages.

Arc welding is used for the joining process. Pipe Design O gms gms 1 2 3 mean Table 1: Diameter of inner barrel is and its length is and consequently the diameter of the shaft and having a length of. This is the rod attached to the surface of inner barrel which does the shelling process with the inner barrel and the spring vanes. This project is meant to achieve the following purposes. It is to 27 in number and measured vertically up from the barrels surface each.

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 utilization with minimal down fine.

These factors are the After studying existing practices of maize shelling design of the power transmission shaft, selection of the and finding the need of maize sheller with better prime mover, type of pulley, appropriate belt design, key fabrication of maize dehusker selection of appropriate bearings support.
