This study focuses on the design, development, and performance evaluation of a motorized multi-fruit juice extraction machine constructed using locally available materials. The machine comprises two major sections: a chopping unit and an extraction unit, along with additional components such as feed hoppers, an auger conveyor housed in a cylindrical barrel, a juice sieve, and a waste outlet. It is powered by a 1.5 hp electric motor and was constructed at a cost of N170,520. During the performance tests on pineapple, orange, and cashew fruits, statistical analyses using split-plot and Nested experimental designs revealed that extraction speed and feed rate significantly influenced juice yield, with p-values of 0.0148 and 0.0018, respectively. Moreover, the extraction speed had a pronounced effect on extraction efficiency (p-value = 0.0080), while the type of fruit had minimal influence. The model validation using ANOVA and diagnostic plots confirmed the assumptions of normality, the absence of outliers, and constant variance. This affordable, locally fabricated machine offers a practical solution for small- to medium-scale fruit juice extraction, reducing the need for costly imported equipment and enhancing juice production efficiency in local communities.
