摘要

Sugarcane juice extraction remains essential for accessing the nutritional and economic value of sugarcane; however, inefficiencies, hygiene concerns, and mechanical limitations in current extractor technologies hinder widespread advancement, especially among small-scale producers. This review investigates the historical development, classification, mechanical design, and performance of sugarcane juice extractors, aiming to bridge existing knowledge gaps in machine types, structural components, and extraction efficiency. The study categorizes extractors by power source (manual, animal-driven, motorized), mechanical design (roller, screw press, hydraulic press, cutter-expeller), and scale of operation, identifying three-roller systems and cutter-expeller designs as leading in efficiency. Key findings include the influence of roller surface modifications, drive mechanisms, and automation on juice yield and safety, with cutter-expeller systems achieving up to 98% efficiency. Waste valorization strategies and sustainability aspects, such as the use of stainless steel and renewable energy integration, are emphasized. Conclusively, this study not only consolidates insights into existing extractor technologies but also proposes pathways for future innovations that are efficient, sustainable, and accessible to both industrial and small-scale users.
