Abstract: A manually operated juice extractor was designed, constructed and evaluated 2005 at the Department of Agricultural Engineering, Federal college of Agriculture, Akure, Ondo State Nigeria. In Nigeria, fruit juices are obtained through hand pressing and electrically operated extractors. The hand pressing method is always tedious and time consuming. That of electrically operated is simple but the epileptic power supply is a limiting factor for its use. This manually operated juice extractor was designed and constructed to save time, improve efficiency, increase capacity and reduction in spoilage and waste. Performance evaluation was carried out with the production of orange and pineapple juices. The results showed that the machine produced efficiencies of 83.86 and 85.38% and extraction capacities recorded were 1.29 kg h 1 and 1.23 kg h 1 for orange and pineapple juices.
