Abstract
Cassava (Manihot esculenta crantz) is one of the alternative sources for low cost carbohydrates and is considered as one of the major crops in the Philippines, Nigeria and Brazil. It is a perishable root crop and easily deteriorates. Hence, the processing of the cassava after harvest is necessary to extend the shelf life of root tubers. This study is therefore on the design and construction of an effective labour less motorized machine of 970mm × 770mm × 1380mm in dimension for the frame, the barrel is 600mm in diameter and 920mm long with a total volume of 0.260m3 for the peeling operation of cassava tubers in rural areas. Locally available materials such as hard wood (mansonia) is used for the barrel, mild steel for the frame were used in constructing the machine. The machine was tested for soaked and un-soaked cassava, 20kg feed per loading per trial. During testing, the maximum length of tubers to feed is 150mm for peeling and the largest diameter of tuber peeled is 70mm. The average peeling efficiency was 80.1%
