ABSTRACT
This Machine is design and fabricate as a prerequisite for the award of a Higher National Diploma.
We sketch different designs which after consideration of many factors like the machine efficiency, the cost of materials e.t.c before we finally embark on this machine.The machine major component are the shaft, the inner barrel, the outer barrel, the conveyor, the tray etc.The machine is build with very strong and well selected materials which enhances the performance of the machine. The machine efficiency is above 80% but less than 100%. The output of the machine is above average so it satisfies the purpose of which it is design.
