Design of an Improve Cassava Peeling Machine
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
All the unit operations involved in the post-harvest processing of cassava such as grating, drying, milling, pressing, sieving, molding, extrusion and frying have been mechanized successfully. However, cassava peeling remains the only unsuccessfully mechanized process which has constituted a bottleneck to the commercial processing and industrialization of cassava tuber utilization. This project work is aimed at developing an improved cassava peeling machine with a minimal loss of useful flesh. The principal parts of this design work includes a hopper, electric motor, shafts, bearings, wire brushes, and a Vbelt attached to the pulley that rotates the shafts embedded with wire brushes. A ten consecutive tests were carried with a total number of ninety-three (93) cassava tubers used. However, out of the ninety-three cassava tubers used for the test, six broken cassava tubers were recorded. The percentage mass of peel (%) by manual and machine, peeling efficiency (%), percentage of broken and unbroken cassava tubers were calculated for. The results showed that the machine is 85% efficient and a minimum percentage peels recorded. Also, the percentage of broken cassava tubers recorded was 5% and this simply means 95% of cassava tubers used for the test were successfully peel without any breakage. To know the actual percentage peel removed by machine and manual, the mass of cassava tubers and mass of peel removed both manually and by machine were used. The results analysis showed that 13.13% was obtained for manual peeling and 15% for machine peeling. Therefore, the machine is expected to cause minimum useful flesh loss.
