Re-design and manufacture a neem seeds thresher for effective threshing of neem seeds.

Abstract

Neem seeds are one of the most sources of oil for both local and industrial use. Mostly it is always threshed manually either by pounding or by the use of stone to remove the kernels from the seeds. Threshing Neem Seeds by the method of pounding or crushing with stone normally contaminate the grains with debris and also crush the seeds when in contact with the ground during crushing with the stone. Grains are also lost due to scattering during crushing and pounding processes, thus reducing the quality of the seeds. This process is slow and tedious hence the output per man per hour is very low. It is on this view that this project is designed to provide a clean and quality Neem Seeds and reduce the labour intensive during threshing. This study will helps to thresh neem seeds fast, effective and efficient. Besides, the cost in threshing Neem Seeds is reduced and the efficiency of the threshing is improved. A manual/motorized threshing machine is thus manufactured to curtail the above mentioned situations. Hence with the presence of this machine, Neem Seeds can be thresh with ease and with a great output per day and quality seed . This artifact is designed to meet all ergonomic purposes the common material to be used for the manufacturing is mild steel because it is affordable and easy to weld. However the fan blade should made to have enough air when revolving. This will help to blow the shells very easily from the kernels during the threshing process.
