Design, Fabrication And Performance Evaluation Of A Rice De-Stoning Machine:- Uche Solomon U

ABSTRACT

 A Rice de-stoning machine was fabricated in this study using locally sourced standard materials. The machine is developed to solve the problem associated with rice processing, particularly the removal ofstones and other impurities. This research was carried out to modify existing rice destoner for the purpose of increasing its capacity, efficiency and further reducing the cost implications from the already existing mechanisms. A 0.5HP vibratory motor motor with a speed of 2840 r min-1 was intended to power the destoning machine and Galvanized steel was used majorly for the fabrication of component parts for ease of machining, assembling, maintenance and affordability. The efficiency in separating and de-stoning rice was assessed, along with the amount ofimpurities remaining after separation. The total cost of producing one unit of the rice de-stoning machine is Four hundred and Fifty Thousand Naira only.(M450,540
