DRYING PERFORMANCE OF JACKFRUIT DODOL USING RICE HUSK ENERGY ON HOUSEHOLD IN LOMBOK, INDONESIA

Abstract

Rice husk is a cheap fuel source and it is abundantly available in Indonesia. The heat exchanger mechanism was used in other to, the dried material was not contaminated by the combustion gases. The drying system consists of three components which include the furnace, heat exchanger pipe, and drying chamber. The heat exchanger pipe connects the furnace with the drying chamber and transfers the heat generated from rice husk burning to the drying chamber. The drying chamber was the section for drying the jackfruit dodol. It consists of 4 shelves and is equipped with an exhaust fan. The results showed capable that the dryer decreases moisture faster than conventional methods. The moisture content of jackfruit dodol reduced from 29% to 23.7% within 600 minutes and the average drying chamber efficiency was 25.3%.
