Aplikasi Oven Pengering Biji Pala Dengan Memanfaatkan Udara Panas Tungku Pembakaran

Abstract

The nutmeg dryer oven is a dryer with a capacity of 5 kg which functions to dry the nutmeg seeds by utilizing hot air from the furnace at a temperature range of 60-80 ⁰C. The purpose of this study is to design and manufacture nutmeg dryers to use hot air from the furnace. The methodology used includes the design, manufacturing and testing of tools. From the results of the study conducted for 5 hours the following temperatures were obtained; in the first hour the temperature in the oven room is 75 ⁰C in the 60^th minute, in the second hour the temperature in the oven room is 80 ⁰C in the 30^th and 55^th minutes, in the third hour the maximum temperature in the oven is 80 ⁰C in the 30^th minute and 45^th minutes, at the fourth hour the oven room temperature is 80⁰C at the 40^th and 50^th minutes and at the fifth hour the oven room temperature is at 80⁰C at the 45^th and 55^th minutes. From the test results of drying the nutmeg seeds using this drying oven, the nutmeg seed dryness level is around ± 9.15% and this corresponds to the nutmeg seeds on the market which is 8% - 11%. This oven is also very economical in terms of fuel use and drying time which only takes ± 5 hours.
