Abstract/ Executive Summary:

Bangladesh produced 1.0 million ton jackfruit and price of jackfruit remain very low during harvesting season. The unripe fruits could be used in vegetable curries and pickles. If we can increase consumption of immature jackfruit, mature fruit loss could be reduced. Main problem of such consumption was difficulty in peeling. The main aim of the research was to develop a jackfruit peeler and to solve the problems. A power operated jackfruit peeler was designed and fabricated in the workshop of FMP Engineering Division of BARI Gazipur during 2017-18. The peeler was modified to improve the performance during 2018-19. The peeler was made with locally available materials. The peeler is electric power operated machine where power transmitted to the cutting blades and jackfruit was rotated. Mechanical peeling was done with two phases: in first phase minimum thickness was peeled and optimum peeling was done in second phase. Capacity of the mechanical peeling was 3.7, 3 and 6 times higher than the manual peeling for unripe jackfruit, papaya and sweet guard, respectively. The experiment will be conducted in the following year to evaluate the performance of the peeler for different fruits and vegetables.

Keywords: Jackfruit, Peeler, performance

Location: FMPE Division workshop, BARI, Gazipur

Start Date: 00-00-2017

End Date: 00-00-2019

Program Area: Farm Mechanization

Commodity: Peeler, Jackfruit

Objectives:

To design and fabricate a power operated jackfruit peeler
To test performance the power operated jackfruit peeler

Methodology:

The power operated jackfruit peeler was designed and a drawing was created with AutoCAD software. A schematic diagram of the jackfruit peeler is shown. Then the power operated fruit peeler was fabricated in the workshop of FMP Engineering Division of BARI Gazipur during 2017-18. The fabrication of the peeler was done in the workshop with locally available materials. The machine had main frame, fruit holder, peeling blade and safety cover. The function of fruit holder is to hold the fruit. The fruit holder was rotating with the motor power when the cutting process was carried out. The peeling blade was used for peeling the skin of the fruit. The switch function is to control the process and the safety cover was used for protect the user while the machine operates. Power transmission: The jackfruit peeler was operated with 0.37 kW AC single phase electric motor. Speed of the motor rotation was 1400rpm. Finally, the speed of the fruit base was 60 rpm. Modification: The peeler was modified during 2018-19 to improve the peeling performance. The base cover was shortened to go down the cutter blade up to the end. This modification helped to peel the fruit completely. The fruit holder was modified with hook to hold the fruit tightly. Main modification was done in the blade holder and the blade design. The blade holder was straight before which was modified with curved holder. The blade was modified to change the peeling thickness based on fruit size. Working Principle of the Slicer: The peeler is power operated machine and power transmitted to the blades through the screw shaft. Fruit setting was done manually. A jackfruit was place on the fruit holder and make fixed tighten by screw shaft. The cutter was placed in side position. The cutter was adjusted according to diameter of the jackfruit. Switch of the electric motor was started which will allow the jackfruit to rotate. With the rotation of the jackfruit the cutter was gradually go down and peeling was occurred. Thickness of cutting slice could be changed.

Achievement/Findings:

A mechanical power operated jackfruit peeler was redesigned with some modification and fabricated at FMPE Division of BARI, Gazipur. Capacity of the mechanical peeling was much higher than that of manual peeling. Critical aspects of this machine are the hygienic factor and the mechanical components. The experiment will be conducted in the following year to evaluate the performance of the peeler for different fruits and vegetables.
