Abstract
This paper reveals design of a rice de-stoner for separating stones from rice based on their different properties. It has a sieve with opening based on the size of rice grain to separate the rice from the stones larger than it and also a second sieve which allows sands and stones smaller than the rice only. Both sieves are vibrated, powered by a 0.50kW DC and rotational speed of 700rpm electric motor. The de-stoner has the efficiency of 80% and mass flow rate of 2.10 kg/s which is equivalent to 7.50t/hr capacity. The design of the de-stoner was carried out economically. A machine of this nature can be manufactured for small entrepreneurs and rural level applications in the developing countries, due to its low cost of and easy production and maintenance, where rice is locally produced for better quality and quantity.
