ABSTRACT
The need to dehull seeds such as maize, beans, etc for further processing for various food products has become imperative. Thus, this work aimed at developing and fabricating a dry bean seed de-hulling machine using abrasive disc design concept. The de-hulling mechanisms utilizes eight abrasive discs attached to the shaft in the de-hulling chamber of the machine. The de-hulling machine was specifically developed for dry bean seed processing however, could also work for other seed such as maize, soya beans and guinea corn. The chaffs leave the machine through a slot created under the polishing chamber while the de-hulled seed fall through the seed outlet under the action of gravity into a bowl or sack placed under the polishing chamber. Preliminary evaluation revealed that the machine had output capacity of 1.04 ton per hour with overall efficiency of 83.60 %.
