An Innovative Design and Development of A Cassava Peeling Machine

The study was the design and development of a cassava peeling machine to reduce drudgery and improve the productivity of cassava processing into various foods. The cassava peeling machine consists of the peeling drum (with both knife and abrasive embedded), conveyor, electric motor, and speed reducer. The machine was designed using solid work software. The peeler was evaluated with cassava root length of about 300mm. The speed range of 90-120rpm was used to test the performance of the peeler. The average capacity of the developed machine was 450kg/h, with a peeling efficiency of 90%. The root loss of 5% and peel retention of 5% were obtained during machine test. The various shapes of cassava roots do not affect the machine's functionality as it functions well on the different shapes and sizes of cassava roots. Results also show that the machine is affordable and efficient and is recommended to improve the processing productivity of cassava food products. It is therefore, recommended that further research be carried out on cassava roots geometry and thickness to further improve the peeling efficiency of the machine. Modelling of the cassava peeling process should be studied, taking into consideration the physical parameters; towards identifying any flaw that needs improvement in the present design. More research should be carried on the utilization of alternative sources of energy like solar to power the machine at a minimal energy cost

Development of a Reciprocating Motion Cassava Slicing Machine

The development of cassava reciprocating slicing machine was achieved using locally sourced materials that is affordable and effective. Although hand slicing is the cheapest form of slicing operation, but it has posed to be labour intensive, time-wasting, and hazardous. This necessitated the design and development of a cassava slicing machine. The machine's capacity for boiled and unboiled cassava root was calculated as 22.8kg/hr, with an average slicing time of 0.005hr for boiled and 0.00455hr for unboiled cassava root. The machine has low labour requirements and power consumption. The cassava reciprocating slicing machine use electric motor of 0.75kw (1hp) rating, with a speed of 99rpm. The machine is made with stainless steel for the slicing section and other components with mild steel and has an overall efficiency of 91.05%. The machine reduces drudgery and also enhances mass production of cassava chips, implying more profit
