Development and Evaluation of a Hand Operated Fruit Juice Extractor

Abstract

A hand operated jack friut juice extrator was developed. It was fabricated with a metallic cylinderical container perforated at the bottom with 2.38 mm size holes. The hole to hole distance was maintained to 3.18 mm. A round plate was made and attached to a handle to move up and down inside the container. Four fruits and vegetable such as pineapple, tomato, lemon, and jack fruit were chosen for performance test of the extractor. The juice yields (%) for pineapple, tomato, lemon and jackfruit were found 58%, 52.8%, 22.8% and 45%, respectively. The cost of fabrication of the extractor was Tk. 150 only. The device may be very useful for extraction of juice of other similar fruits and vegetables.
