Abstract

DESIGN OF A PNEUMATICALLY OPERATED MAIZE GRINDER

Fatoki, Francis Tekenate*, Isaac, Okwu Elemchuku and Leol, Anthony Kpegele

ABSTRACT

This research is centred on the design of a pneumatically operated maize processor. It serves as a shift from over reliance on the Nigerian National power grid and fossil fuel generators which have been the major ways for processing agricultural products in Nigeria. This study also analyses pneumatic machine operations and how it can be fused into agricultural use. A set of rotor blades in a cylindrical housing is connected to a shaft at an angle that if pressurised air (13bar, 33.86CFM) impinges on the blade tips. This causes the blades to rotate. This subsequent rotation is the production of mechanical energy generated from the action of the compressed air, which is then used to run a belt and pulley system connected to the grinding bits of the maize processor assembly for work to be done. The sum cost of operation is considerable low given that air is the source of fuel. The Volumetric Efficiency of this pneumatically operated maize grinder obtained is 90.76%.
