The traditional method of slicing and shredding of vegetables involved a lot of physical labor and material wastes. Therefore, in order to improve the processing method and enhance its hygienic level, there is the need of mechanization of the slicing method. For last few years, researchers are putting their efforts in developing technically feasible and economically viable multipurpose vegetable slicer-cum shredder. The existing slicers and shredder are not meeting the actual requirement of small scale processing unit and there is need to develop equipment in which both unit operations (slicing and shredding), can be taken place. Therefore, a need was felt to design equipment to slice/shred various vegetables at a small scale level. The known amount of peeled product was sliced / shredded at four different rpm and three replications were made. The machine performance was evaluated with regard to the capacity, roundness of sliced vegetables, breakage per cent and wastage during processing. On 500 rpm, maximum performance efficiency (86.33 per cent), slicing efficiency (85.67per cent), capacity (94.33 kg/h), and effective capacity (81 kg/h) was observed and on the other hand minimum mechanical loss (5 per cent) and breakage per cent (14.33 per cent) was observed. Potato slices for producing chips have 0.92 RI. The cost benefit ratio for processing of potatoes was found to be 2.28 with a paybperiod of 4 years.
