A Development and Evaluation of a Multipurpose Fruit Pulping Machine
Keywords:
Extraction efficiency, extraction loss, fruit, juice yield, pulping machineAbstract
A multipurpose fruit pulping machine was designed, constructed and evaluated for performance using oranges, watermelon, pineapple, and tangerine. The machine was fabricated using locally available construction materials. The essential components of the machine include a feeding hopper, top cover, worm shaft, juice sieve, juice collector, waste outlet, transmission belt, main frame, pulleys and bearings. In operation, the worm shaft conveys, crushes, presses and squeezes the fruit to extract the juice. The juice extracted is filtered through the juice sieve into the juice collector while the residual waste is discharged through the waste outlet. The design analysis of the components provided the data that were used in the sizing, fabrication and assembling of the machine. Performance tests were carried out using oranges, watermelon, pineapple, and tangerine that were introduced into the machine. The performance indicators considered were percentage juice yield, extraction efficiency and extraction loss. Results showed that pineapple was leading in juice extraction efficiency (91.2%, followed by watermelon (90.5%). Further, it was found that watermelon was leading in juice yield (85.1%) and the last was tangerine (69.1%). The results also demonstrated that watermelon (2.9%) was observed to have the highest juice extraction loss, and the orange (2.3%) was the least. Powered by a 3Hp single-phase electric motor, the machine has a capacity of 1.24M3/h. The machine is simple to operate and maintain, therefore it is recommended for smallholder and local fruit juice processors.
