Design and construction of a motorised potato chipper.

Abstract

This project report describes the design and fabrication of a portable motorized potato chipper aimed at reducing labour, saving time and increasing productivity of potato chipping, in semi and urban-centres of Uganda where the demand for potato chips is on increase. Component parts of the potato chipper were designed, fabricated and assembled into portable prototype. In comparison with hand chipping Capacity of 24 kg/h and yielding non-uniform chips, the prototype was tested giving an average production capacity of 339.Kg/hr with an efficiency of 93%, and able to chip potatoes to uniform square cross-sections of 10mm x 10mm. The calculated rate of return is 9.5% in only 11 days to recover the initial investment. Keywords: Potato Chipper, Design, Fabrication, Motorized Operation.
