CONSTRUCTION OF A JUICE EXTRACTOR MACHINE
ABSTRACT
This project (construction of a simple size reduction machine) it was constructed locally with the use of local materials and tools in I. M. T. mechanical engineering workshop. The various parts of the equipment were constructed separately using mild steel before finally coupled.
During the construction, the conveyors and its housing where first constructed. It consists of a shaft with helical rod wound round it. The paper was measured out and welded from a mild steel sheet of length of 320mm by 60mm with a thickness of 1 mm and it has the following dimension:
Height of hopper- 160mm
Upper part of the hopper – 140mm diameter
Lower part of the hopper – 100mm diameter
The conveyor was fixed into its housing and welded to the shaft. The grinding chamber was 0welded separately and coupled to the grinding discs. The pressure screw fabricated was welded to the hopper. The U channel was joined to the base stand by welding and existing setup the bearing pulley and the manual handle were all coupled.
It was filled to smoothen the sharp edge and finally painted for corrosion resistance.
After the construction work test run was carried out using the grains of wet maize and dried maize. The result shows a greater efficiency in using wet maize.
