Development of Candlenut Shell Carbonization Tool Using a Vertical Multi Chambers

Candlenut shell, a solid waste from the process of taking candlenut seeds, is potentially able to improve the quality of the life of rural community by converting it to charcoals. It seems that the local people has difficulty to produce the charcoals from the candlenut shell. The aims of the research are to produce a carbonization tool using energy derived from the candlenut shells and to determine the tool's capacity. The tool was designed by utilizing Autodesk Inventor 2018 software. The result shows that the tool has three vertical O60cm x 30cm chambers that facilitate the carbonization process. The main components are a metal drum, a reservoir, two chamber barriers, and an exhaust pipe. It is also found that the best result of the tool is to process 24kg of the shell with 7.75 hours of processing time. Thus, the tool can carbonize the candlenut shell without any additional energy and the production of the charcoals is raised three times in one day.
