ABSTRACT

This paper presents the development of a modified manually operated fruit juice extractor. The modifications were made by developing a power cylinder which can be opened for washing operation and other activities without disassembling the whole system, introducing a U-shaped container to serve as collection chamber, increasing the number of perforations through which the juice drain into the collection chamber and reducing the machines’ cost of production. To develop the open-able power cylinder, the stainless steel pipe used for constructing it was sectioned horizontally into two equal parts and angle irons were welded to the edges to prevent leakage and keep the sectioned parts joined. To reduce the cost of production, the machine was produced by the reutilization of locally available materials. When tested for fresh water melon, orange and pineapple fruits, results showed that the average juice yields were 70.05%, 58.16% and 60.20% respectively. The extraction efficiencies were 75.82%, 73.08% and 73.75% respectively. The extraction losses were 1.5%, 4.0% and 1.7% respectively. The machine is simple to operate, easy to maintain and cheap to construct. The cost of producing the machine was N19,850 which makes it affordable for small scale farmers and industries in rural communities.
