Maximum juice yield of 64.6 % extraction efficiency of 68.2 % and corresponding extraction loss of 7.05 % respectively were obtained from the 16 slice lengths orange fruit. The juice yield, extraction loss and extraction efficiency were determined by standard formula and methods. The fruits were washed and weights (1 kg, 1.5kg and 2 kg respectively) of fruit slice (8 and 16 slices) were then processed using the extractor to extract the juice. I designed, constructed and evaluated the performance of the extractor in the laboratory using orange fruits. These products are essential for human and animal growth, aid metabolic activities and improve health standards. Incidentally, there is an increasing demand for fruits juices among people of all age groups due to the vitamins, mineral and fiber contents. Several varieties of juicy fruits are available in abundant quantities in many parts of Nigeria, most especially during the harvesting seasons. This skin can also be used in manufacturing of sandals and belts. The maximum deformation of the prototype to be 4.05x 10-5 mm and stress on the prototype while peeling the jackfruit is given by 5.75 x 105 N/m2.The waste skin can now be used as manure in agriculture. In this work stage-I is designed and analyzed its structural stability in Ansys 18.1 and a prototype is developed. Thus the fruits are separated from the thick outer surface in a tray kept below. The stem is in the shape of a bell and so that the fruits don’t get damaged much. Now the cylindrical blade is pushed down slowly and the fruits around the stem are cut. The skinless jackfruit is made to rotate by means of motor. In this blade a sliding attachment is given so that it can slide up and down by means of human power. The second stage consists of a semi cylindrical blade which is attached at the top of jackfruit below the motor. The fruit is now ready for the second stage where the stem of the fruit is taken out from it. In the first section the outer skin of the jackfruit is peeled using a movable blade which is attached with a spring which proceeds up and down by means of rotation from the motor. The main objective of this project is to construct an economical machine to reduce human efforts in extracting the fruits from the stem of a jackfruit. This machine is devised to extract the fruits from a jackfruit in a better way without involving heavy human work. Many researchers have developed peeling machines for fruits. The removal of the fruits from its shell is a very much effort consuming process. Jackfruit is a fruit with thicker outer skin and a hard shell.
