DEVELOPMENT OF A VARIABLE SIZE NUT CRACKER CIGR Journal
Ogundare, Adebayo; Ojolo, Sunday.
In this work, a variable size nut cracking machine has been designed and constructed to improve the efficiency of shelling operation of quite a number of nuts. The machine is designed to be adaptable to the cracking requirements of some number of nuts, whose shell can be processed to brittleness. The machine performs two operations, shelling of the nut and separation of the shell from the nut. The machine comprises of a hopper, rectangular box housing the cracking drum and compression plate, and a two stage agitated separating tray (to sort the nut from the shell), all supported by a frame. The cracking drum, which is driven by a v-belt connected to an electric motor, also provide the agitation to the separating tray via a v-belt connected a cam mounted...

Plug Flow Analysis for the Design of the Compaction Region of a Tapered Screw Extruder Biomass Briquetting Machine CIGR Journal
Orisaleye, Ifeoluwa; Ojolo, Sunday.
The study of compaction or solids conveying in a screw extruder has been carried out majorly on the straight screws using the plug flow analysis. Despite this, the analysis of the straight screw appears to be complex as contained in existing literatures based on the force and torque balance. The tapered screw, which is considered to be an effective option for biomass compaction, introduces greater complications because the geometry is constantly changing. In this study, a method based on the traction and retardation mechanism of friction is developed for a fully unwound screw channel utilizing only the force balances. The procedure has been used to carry out a parametric analysis of the tapered screw extruder for a screw press biomass briquetting machine....
