Abstract

The main aim of the present study is to design, fabricate and evaluate a slicing machine for potato chips to be used in small and medium production units locally available materials like stainless steel and mild steel were used in fabrication. The obtained results indicated that the machine productivity increased from 256.021 to 387.670, 201.879 to 448.670 and 250.070 to 392.290 kg h-1 with increasing potato size from small to large, slice thickness from 1.0 to 2.5 mm and slice thickness from 1.0 to 2.5 mm, respectively. The uniformity index increased from 76.598 to 83.372, 73.472 to 87.103 and 73.615 to 86.422% with increasing potato size from small to large, slice thickness from 1.0 to 2.5 mm and slicer thickness from 1.0 to 2.5 mm, respectively. The cutting efficiency increased from 87.582 to 93.305 and 89.531 to 92.209 % with increasing potato size from small to large, slice thickness from 1.0 to 2.5 mm, respectively, while it decreased from 92.325 to 89.829% with increasing cutting speed from 250 to 550 rpm, respectively. The specific energy consumption decreased from 2.446 to 1.663, 3.042 to 1.464 and 2.608 to 1.578 W.h kg-1 with increasing potato size from small to large, slice thickness from 1.0 to 2.5 mm and cutting speed from 250 to 550 rpm, respectively.The total cost of slicing machine decreased from 0.085 to 0.055, 0.102 to 0.044 and 0.091 to 0.054 LE kg-1 with increasing potato size from small to large, slice thickness from 1.0 to 2.5 mm and cutting speed from 250 to 550 rpm, respectively.
