Thus, the operation and maintenance is quite easy. The shredding processing machine is made up of simple components that can be easily assembled. The performance test evaluation shows that the machine driven by a 1hp electric motor has an average performance cutting time of 30.2seconds for a full hopper volume of 2319.8cm3 which is equivalent to 78.87kg of vegetables with an efficiency of 89.35% and a throughput capacity of 9400.48kg/h. The vegetable shredding machine which works on shear principle was designed and fabricated using locally sourced materials from the opinion of new idea and tested. Shredding of vegetables is a process of cutting vegetables into thin slices or pieces using a sharp knife, food processor or grater. In an attempt to add value to vegetables before domestically using them, a motorized electric- driven machine has been developed in order to circumvent the challenges of time consumption, contamination and injuries associated with the manual process of shredding vegetables using sharp knife. With the growing world population, the need for vegetables due to its economic importance, nutritional value and viability cannot be overemphasized. The device match the need of the oil bean processors and with adequate maintenance and/or management, it would ameliorate the difficulties involved in oil bean processing and, therefore boost the farmers' production. The bill of engineering measurement and evaluation revealed that the machine was fabricated at a total cost of ₦91,353.00. The machine was tested for performance and it recorded an efficiency of 96.64% with minimal damage of the product. Factors such as physical and mechanical properties of oil bean seeds, mechanical properties of construction materials, mach inability or deformability of construction materials, wear resistance, availability of power and cost of materials were considered in the fabrication of the device. The design was based on the engineering standard and specifications. 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.Ī hand fed African oil bean slicing machine which would be affordable, simple to operate and easy to maintain by local and/or small scale farmers and processors was designed and fabricated with locally available materials. 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. h-1.Ī multi-crop slicing machine was designed, fabricated and evaluated for performance. This machine has sliced efficiency of about 90.46% with effective capacity of 648.21 kg. The results of the test carried out showed that the time required to slice equal length of Aloe vera with the machine is 24 times less than the manual process. The machine is simple in construction, easy to operate and does not require special skill. The performance evaluation of the machine was evaluated under three belt conveyor speed (0.251, 0.188 and 0.125 m. This machine mainly consist of belt conveyor, feed and conveyor roller, chain sprockets, knives, power transmission mechanism and frame. The design and development of Aloe vera leaf slicing machine is to solve the aforementioned problems. Presently, manual slicing is most commonly followed in Indian Aloe industries, which is time consuming, tedious, unhygienic, expensive and sometimes hazardous. In the manufacturing of whole leaf Aloe Vera powder, slicing is one of the important unit operations after trimming. Aloe Vera has a number of uses and mainly they are used as a food preservative and herbal medicine. The Aloe plant belongs to a member of the family Liliaceae, which comprises more than 360 different species.
