This banana slicer mainly consists of feeders for round slicing, cutter, power transmission mechanism, base support and frame. A power operated rotary banana slicer suitable for small scale processing was designed and developed based on engi-neering properties of banana varieties, namely Nendran and Dwarf Cavendish. Design and development of power operated banana slicer for small scale food processing industries. Sonawane S.P., Sharma G.P., Pandya A.C., 2011.

The result of the study shows that the machine can slice root and tuber crops satisfactorily with slices ranging from 8 mm to 9 mm thickness were obtained. The machine is therefore observed to perform best at the optimum operating speed of 41 rpm for all the crops selected except carrot. A throughput capacity of 135.7 kg/h at a speed of 41 rpm and efficiency of 96% was obtained for yam. Best result for small and medium size grade of onion we achieved at speed of 41 rpm with capacities and efficiencies of 44.6 kg/h, 71.6 kg/h, 91.7% and 96.4% respectively. Medium and large size samples gave good result for potato at a speed of 41 rpm with capacities and efficiencies of 72.8 kg/h, 88.9 kg/h, 97.9% and 94.8% respectively. A speed of 46 rpm was found to favour the slicing of large size crops only, while a throughput capacity of 48.9 kg/h and efficiency of 95.4% were obtained for carrot. The parameters that were investigated were slicing efficiency and throughput capacity. The performance of the machine was evaluated in slicing four selected crops (carrot, potato, onion and yam), grouped into three sizes (small, medium and large) at five machine speeds of 39 rpm, 41 rpm, 43 rpm, 46 rpm and 48 rpm respectively. The machine is powered by a three-phase, 1400 rpm, and 2 kW electric motor. The major components of the machine include the hopper, mainframe, conveying disc, slicing unit, slicing shaft, idler shaft, pulley, bearing, electric motor base and outlet. It was also observed that the machine could slice onion bulbs, carrots and Irish potatoes satisfactorily with slice thicknesses ranging from 5mm to 6mm.Ī multi-crop slicing machine was designed, fabricated and evaluated for performance. The throughput capacities developed by the slicer were affected by slicing speeds and ranged from 20.52-44.28 kg/hr. Results showed that the highest mean slicing efficiency of 87.6% was attained from the machine when slicing small-sized Irish potatoes at rotational speed of 58 rpm while the lowest mean slicing efficiency of 60.7% was attained from the machine when slicing medium-sized onion bulbs at rotational speed of 69 rpm. The parameters investigated were slicing efficiency and throughput capacity. The performance of the machine was evaluated using three selected crops (onion bulbs, carrots, and Irish potatoes) grouped into small-sized samples (22.62-33.14 mm) and medium-sized samples (33.35-49.9) at four machine speeds of 53, 58, 62, and 69 rpm. The machine was powered by a 0.25hp, single phase electric motor.

A slicing machine, equipped with two slicing blades was designed, fabricated and evaluated for performance. Slicing machine is useful for farmers in chopping of fodder and for crop processing industries in slicing of vegetables in readiness for other processing activities. Type: Research The purpose of this study was to develop an efficient and ergonomically safe slicing machine that is affordable to a small scale farmer.
