Design Fabrications Prototype The fabrication of a prototype papaya pickled Atchara extractor machine is a crucial development in the food processing industry, as it aims to streamline the extraction process of this popular Filipino condiment. Atchara is a traditional pickled side dish made from green papaya, carrots, and other vegetables, and its preparation typically involves time-consuming manual labor. With the increasing demand for Atchara in the market, there is a need for an efficient and cost-effective extraction machine to meet this demand. A manually operated juice extractor was designed and fabricated using locally sourced materials. The extractor consists of a base table, column support, lifting flatform, cylinder holder, plunger plate, cylinder housing and power by bottled hydraulic jack unit. The development process followed the ADDIE model, ensuring a systematic approach to design and implementation. The performance of the extractor machine was evaluated based on three key metrics: throughput capacity, extraction rate, and extraction efficiency. The results of the performance tests indicated that the extractor machine had a throughput capacity ranging from 0.886 kg/min to 3.111 kg/min, demonstrating its ability to process a significant amount of papaya. The extraction rates were measured at 0.304 kg/min and 0.2 kg/min, equivalent to 5.07 g/s and 3.34 g/s, respectively, showcasing the machine's efficiency in extracting pulp from the papaya. Furthermore, the extraction efficiency of the machine was found to be between 24.0% and 93.3%, with a mean efficiency of 67.32%. These results highlight the effectiveness of the extractor machine in extracting pulp from papaya while maintaining a high level of efficiency. Overall, the study demonstrates the feasibility and performance of the fabricated prototype papaya pickled atchara extractor machine for commercial applications. 2025-12-03T10:01:33Z 2025-12-03T10:01:33Z 2025 journal article Ronaldo C.
