This is made up of flat tiny metal welded round the inner barrel together it the spikes.

The design parameter for corn sheller machine are:. Bleak, haunting, and yet still somehow hopeful, Winter’s Bone is writer-director Debra Granik’s best work yet — and it boasts [ This project involved the design, fabrication and testing of a maize sheller.

For more project materials.

The budget of the sheller was ksh. A machine for corn shelling is highly and greatly needed to consistency of usage of corn in local and international levels. Infact to summarize all this, junked food that are baked in supermarket today are mostly involves corn in making them. This is the outer funnel that collects the shelled corn from the conveyor to the outside.

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.


Work Plan All rights reserved by www. Buy Mirror for Humanity: From the collected results, the machine efficiency, dehusking efficiency and percentage of broken grains was calculated.

Determination of Driving Power. It of hand tools dehuskdr shelling, while as observed animals were consists of feeder from where the maize is inserted.


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. The speaker tells us that the poet is like an acrobat, always risking both absurdity and death as [ These and as a part of our academic project, we have developed fabrication of maize dehusker includes: 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 owners find it difficult to afford the machines. The diagram is shown below. This is curved mild steel welded below the perforated outer barrel inclined to enable the falling out of the shelled corn to the receptacle. 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.

Through this project, we were able to develop a cheap and an efficient sheller which could be easily afforded by small scale farmers. 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. Pair this method with [ The design parameter for corn sheller machine are: It is therefore very rare to see any Nigerian who has not tested it in one way or the other.

The sheller was designed using a CAD software known as solid works. There were hand operated maize shellers which were cumbersome to use. This Page is automatically generated based on what Facebook users are interested in, and not affiliated with or endorsed by anyone associated [ 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.

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

Hence this sheller can be afforded by small scale farmers. 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. In the light of this as technology advance forward, an introduction of this machine sheller made manifest and come into existence which is maizf stressless, easy to operate, low costing, and time reduction with high degree of production volume and efficiency.

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

The objective of this work is to design fabgication develop an improved maize shelling machine in terms of better time management, affordable cost. This value is low compared to the prices at which other shellers were retailing in the market at figures of aboutksh. 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. Arc Welding 4 Gear assembly- Gears are manufactured by gear cutting and the gear ratio is 1: Arc welding is used for the joining process.

Below is a complete drawing of the outer barrel shown. It is the part of the machine where the corn is being shelled.

Below is the diagram of the inner barrel.
