| dc.description.abstract | Fermented Plant Juice (FPJ), a potent organic fertilizer made from young plant parts and fast-growing crops, can significantly boost agricultural productivity. Its potential is further heightened by the Philippine Republic Act 10068, encouraging the use of indigenous materials like FPJ in organic farming. However, current manual extraction methods are inefficient and limit large-scale adoption. This study addresses this challenge by developing a screw-type extractor machine for FPJ specifically from soybean and squash refuge. The machine aimed to: increase juice recovery: Manual methods often yield low juice recovery, hindering overall fertilizer production. Reduce labor input: Manual extraction is physically demanding and time-consuming, creating bottlenecks in processing. Improve efficiency and output: A machine-based approach promises faster extraction, higher juice yield and increased production capacity. The extractor, constructed from readily available materials, consists of live key components: feeding hopper, extraction chamber, juice and meat outlet, transmission assembly, main frame. The screw shaft’s rotational speed was the primary variable investigated during performance testing. Compared to manual methods, the extractor significantly improved juice recovery, reaching up to 84.41% at the optimal speed of 15 rpm. Extraction efficiency also exceeded the minimum PAES requirement, highlighting the machine’s effectiveness. Notably, slower speeds yielded higher juice recovery at the expense of extraction rate. With an estimated payback period of 178 days under continuous operation, the extractor offers substantial economic benefits. The daily operating cost is relatively low, and the produced fermented solution is cost-effective. Overall, this study successfully developed a practical and efficient extractor for FPJ from crop refuge. This innovation has the potential to revolutionize organic fertilizer production, promote agricultural sustainability and drive further advancements in this field. Future research could: explore optimized designs for different crop types and larger-scale production and investigate the effectiveness of the extracted FPJ as a fertilizer for various crops. | |
